Healthy Ingredient Swap-Outs

Healthy Ingredient Swap-Outs

White flour vs Whole grain flour

It’s a really scary fact is that this is going to be the first generation where we will outlive our kids. Our Western dietary habits are setting our children up for childhood obesity, diabetes and a whole host of diseases and health condition in their future. Children have never been afflicted with more chronic illnesses and conditions than in present day.

Many parents are unknowingly contributing to this trend . It is frightening to think that the food our children are eating are potentially laying the foundation for mental health problems, cancer, heart attacks, strokes… and the list goes on. 

Unfortunately, there are a number of reasons for this…

  • Highly processed foods tend to be cheaper and more available and these processed foods are void or limited in nutrients but loaded with saturated fats, artificial preservatives, colorings and flavourings that are detrimental to our nervous systems, organs and brain function. 
  • Portion sizes have steadily increased over the years. Do you remember as a kid getting the small cookie and now you just need look at the size of the cookies that are available at Starbucks that little kids are being fed that well exceeds their daily quota of sugar.
  • Both parents are now working in most families, and kids have multiple programs and sports after school resulting in not having time to prepare meals and relying on grabbing some fast food on the road.
  • Normalizing of consuming processed foods as a standard and staple meal or food that our children should consume, as opposed to it being a treat or viewed as unhealthy.
  • Marketing of children’s food products confuse parents into thinking it is a healthy food option, when most packaged and prepared foods are not.
  • Lack of education, understanding and knowledge of how impactful the foods that our children consume are in relation to their behaviours, cognition, mental state, physical health and long-term wellness.

It doesn’t have to be overwhelming to make simple changes to your child’s diet and you don’t have to do it all at once. Making small changes over time and making your children a part of the process are two great way to start building healthier family eating habits. You might be surprised of the snowball effect of good, clean, healthy eating with better moods, energy levels, less outbursts, better sleep, weight loss, skin conditions resolving and even better and healthier relationships with one another. 

The number one goal to remember is to eat CLEAN!

Here are some Clean Eating Principles to incorporate:

  1. Eat food that looks like it has been from its original state ie eating a strawberry as oppose to a strawberry roll up (which looks nothing like it’s original form)
  2. Eat 3 meals and 2 snacks a day
  3. Consume fruit and vegetables on a daily basis for fiber, complex carbohydrates and enzymes. Kids minimum requirement is 5 servings a day
  4. Consume whole grains instead of refined white grained products that are processed and chemically charged
  5. For dinner stick to half the plate being vegetables (salad, cooked vegetables, cut up raw vegetables) and ¼ protein (chicken, fish) and ¼ carbohydrates (pasta, rice, sweet potatoes)
  6. Consume healthy fats each day such as avocado’s, fish, nuts, seeds, and coconut oil
  7. Choose lean proteins such as poultry, fish, wild game, non-GMO soy, legumes or hormone free, grass fed beef.
  8. Stick to healthy portion sizes
  9. Drink lots of water ideally 2-3 liters a day and avoid pop, store bought juices, energy drinks and other processed sugar laden drinks
  10. Avoid sugar and artificial sweeteners, sweetened meals with stevia, swerve, xylitol, honey or with fruits such as apple sauce. 

Don’t know where to start?

Here are some healthy switch outs that you can make to your children’s lunches, whether they are craving salty chips or sugary cookies there are healthy alternatives to reduce their sugar-intake and calories and increase their vitamins, minerals, good fats and healthy proteins.

Healthy Lunch Box Challenge

Healthy Lunch Box Challenge

Mother and son preparing lunchbox in kitchen

It has been a long time since our kids were at school and going back to school this year will not be the typical back-to-school experience. With staggered classes, online learning, COVID-19 looming, as well as kids adjusting to a “new normal” after 6 months off, it’s making for a stressful time. 

But putting lunches together should not be stressful! At Koru Nutrition we want to make sure you have the tools and some lunch ideas to help give your child a solid nutritional foundation, whether they are learning from school or at home. Healthy lunches are not only conducive to optimizing their learning experience, but also help to support healthy immune systems! 

 

Lunch Box Goals

#1. Eat the Rainbow

Health Canada recommends that children 11 and under should be consuming 5 servings of fruit and vegetables daily. If your children are 12 to 13 years, they require 6 servings of fruits and vegetables daily, and for teens 14+ females require at least 7 servings of fruits and vegetables daily and males 14+ need 8 servings of fruits and vegetable a day. 

Canadian Community Health Survey (CCHS) indicates that approximately 70% of children aged four to eight years, and 65% aged nine to 13 years, do not consume the recommended minimum five servings of fruits and vegetables daily (11). Fruits and vegetables contain fiber to help regulate the bowels and support a healthy gut flora. They contain a variety of vitamins, minerals, antioxidants, phytonutrients to support brain health, mood, and immune system. So, it is vital that we ensure our kids are getting these foods into their diet—ideally at every meal!

If your kids don’t like vegetables, it is amazing where you can hide them. Check out these “Green Monster Muffins”.

Goal: Incorporate at least one fruit and one vegetable into your child’s lunch box each day.

 

#2. Choose Healthy Carbohydrates

It’s important to avoid the temptation of putting sugar-laden processed treats into our child’s lunch box. Your kid might be happy in the moment, but you are not doing them any favours with their ability to remain focused, learn and maintain a stable mood throughout the day. Blood sugar imbalances can occur leading to behavioural and emotional challenges both during school hours and after school, which can make it tough on everyone.

Complex carbohydrates not only include the fruits and vegetables above, but they also include whole grains, legumes and lentils. Some healthy options include roasted chickpeas, a whole grain sandwich or wrap, whole grain muffin sweetened with apple sauce (not sugar), left over dinner of brown rice or whole grain pasta, brown or basmati rice (not white rice), or vegetable chilli in a thermos. You can even make some healthy sweet treats from these ingredients such as black bean brownies or chickpea blondies. Complex carbohydrates will help fuel your child’s brain during the day.

Goal: Incorporate 1-2 complex carbohydrates into your child’s lunch box.

 

#3. Don’t Forget Good Fats

We can’t emphasize enough the importance of healthy fats in your child’s diet and avoiding the bad fats, such as saturated fats and trans fats, because these bad fats can displace the good fats from your child’s brain. Healthy fats make up 60% of your brain and are critical to support healthy brain function. Research shows that good fats such as omega-3 can help boost memory and cognition and help support a healthy mood. Healthy fats include raw nuts and seeds, nut/seed butters, eggs, coconut oil, ketogenic recipe snacks, raw energy balls, avocado, and olives, although you may need to avoid nut-based products on days your child is at school. The standard western diet does not tend to provide enough healthy fats for our health, but we can change this!

Goal: Incorporate at least one healthy fat into your child’s lunch.

 

#4. Eat Clean & Lean Protein Sources

Protein has many important functions for the body and the brain. It helps to make neurotransmitters to help us focus, stay motived, plan and problem solve. However, so much of our children’s options for protein are highly processed and loaded with hidden sugars, artificial colourings and preservatives that only serve to hinder their brain function and health as opposed to help it. Examples of these “unhelpful” protein foods include processed deli meats, luncheon meats, hotdogs, processed cheeses, and Cheez Whiz.

Alternatively, healthy proteins include a boiled egg, left over dinner such as chicken, steak, salmon, cans of tuna, seeds, chickpeas, hummus, seaweed, quinoa, non GMO soy, plain Greek yoghurt, kefir, hormone free sausages, protein powder etc. 

Goal: Include a healthy protein into your children’s lunch each day.

 

#5. Stay Hydrated

We all hear that we need to drink water, but it helps to know why. Just a 2% drop of hydration can cause fuzzy short-term memory and a 5% drop in water levels in the body can cause 25- 30% loss of energy. But it is important to consider what your child is drinking as most people, including children, are consuming their excess sugar intake from sugar-sweetened beverages. There is no need to pack juice boxes for kids’ lunches as the health benefits of the fruit juice has been lost in processing leaving a sugar-loaded drink with limited nutritional value. Just stick to good old plain water!

Goal: Have a water bottle packed each day for your child. If they are not partial to plain water, you can use stevia-sweetened flavourings or cut up fruit in it. If it is a hot day add in ice cubes. 

 

Putting It All Together

Following these guidelines, will be a great start to help give your child the nutrients and fuel they need to stay focused and engaged in learning as well as support a healthy immune system, which in these current times is just as important.

So, each day in your child’s lunch aim to include:

      • At least one fruit
      • At least one vegetable
      • 1-2 complex carbohydrates
      • A good fat
      • A healthy protein
      • Water

With these nutritional bases covered, not only will you be providing your child with the foundation for optimal physical functioning, but you may find other improvements such as improved mood, less tantrums, better sleep and better interactions with their peers and family members. 

All the best during this back-to-school season, and good luck with your lunch box challenge!

Top 5 Foods To Boost Your Libido

Top 5 Foods To Boost Your Libido

Woman Eating Chocolate

    Lack of libido can create problems for relationships and couple’s ability to feel connected. There can be a number of factors that impact a person’s desire to “get frisky”; including psychological reasons such as stress, depression, and anxiety, medications, self-esteem, and so on. Low libido may also be due to hormones being out of balance, or circulatory problems such as poor blood flow.

    Consuming a diet high in healthy fats, whole fruits and vegetables, and antioxidants is a good start to supporting a healthy libido; and avoiding trans fats and saturated fats, sugar, and processed foods can help too. But are there any foods that can specifically help boost your sex drive and performance?

    Yes!

    Here are our top 5 foods that you might want to incorporate into you and or your partner’s diet to help keep the “fire” going or to get that “spark” started.

    #1. Ginkgo Biloba

    Ginkgo Biloba is a a tree, native to China, that has been grown for thousands of years for a variety of uses. Ginkgo has the ability to improve blood levels of nitric oxide, which improves circulation via the dilation of blood vessels (1).

    As a result, ginkgo biloba may also be useful for treating various symptoms of sexual dysfunction by improving blood flow to those areas of the body.

    Research has been done on the use of ginkgo biloba for antidepressant-induced sexual dysfunction. After consuming 60–120 mg of ginkgo biolba daily both male and female participants said they experienced positive effect on all 4 phases of the sexual response cycle: desire, excitement (erection and lubrication), orgasm, and resolution (afterglow), although effects appeared stronger in female participants (2). This herb can be consumed in capsule, tablet, liquid extract, and dried leaves/tea form (2).

    #2. Eat Chocolate

    Throughout history, chocolate has been a symbol of desire. Not just because of its delicious taste, but because of its power to improve sexual pleasure.

    Dark chocolate increases serotonin and dopamine levels in the brain, making us happy and help put us in the ‘mood’. Chocolate also contains phenylethylamine, which is a compound that we have been shown to produce when we are in love. Given that low mood and stress can be strongly linked with lower sex drive, a few squares of dark chocolate daily is a good way to pump up the passion. Plus, cocoa increases blood flow, which aids in stimulation during sex. 

    As a result, chocolate can produce some aphrodisiac feelings of love and mood-lifting effects. Although the role it plays in boosting a healthy libido may be more psychological than physical (3,4).

    #3 Pistachio Nuts

    Pistachios may have a variety of health benefits, including helping lower blood pressure, control weight and reduce the risk of heart disease (5,6,7).

    Moreover, they may also help reduce symptoms of erectile dysfunction. In one small study, men who consumed 3.5 ounces (100 grams) of pistachio nuts per day for three weeks experienced increased blood flow to the penis and firmer erections (8).

     You can try our Cranberry Pistachio Bark for inspiration!

    #4 Oysters

    Research shared at a 2005 conference of the American Chemical Society that oysters, clams, and scallops contain compounds that raise testosterone and estrogen levels. This is due in part to their vitamin D and zinc levels (9). A boost in healthy hormone production translates into heightened sexual desire in many cases.

    As noted above, oysters are an excellent source of zinc and vitamin D. Six raw oysters contain 32 mg, or 291% of the Daily Value for zinc, and 269 IU or 67% of your Recommended Daily Intake for vitamin D; both of which can help boost testosterone levels, and subsequently aid in blood flow to sexual organs in both genders.

    Don’t care for mollusks? Feast on lobster or crab instead. Both types of shellfish are loaded with zinc too (9).

    #5 Maca

    Maca (Lepidium meyenii) is a root vegetable that mainly grows in the Andes of central Peru. Maca is a cruciferous vegetable related to broccoli, cauliflower, cabbage and kale. It has been used for years to enhance fertility and sex drive.

    A 12-week study noted that 42% of men who took 1,500–3,000 mg of maca daily experienced an increased sex drive (10). Furthermore, in a review of 4 studies in 131 people, taking maca consistently for at least 6 weeks improved sexual desire. It also helped treat mild erectile dysfunction in men (11).

    Additionally, some evidence suggests that maca may help combat the loss in libido that may occur as a side effect of certain antidepressant medications (12).

    Most studies found that taking 1.5–3.5 grams daily for at least 2–12 weeks was sufficient to boost libido (13, 14). You can buy supplements in various forms including powders, capsules, and liquid extracts.

     

    So, eat a whole foods-based diet with lots of fresh fruits and vegetables, incorporating our top 5 foods to boost your libido, to kick your sex drive into overdrive. Feel the love!

    Top 10 Health Benefits of Sex

    Top 10 Health Benefits of Sex

    Ketogenic Meal

    cOutside of the probable immediate pleasure, sexual activity (especially on a regular basis) has some other surprising health benefits! Sexual activity, whether intercourse or masturbation, can offer many benefits to all facets of your life – Including physical, intellectual, emotional, psychological and social advantages.

    So, here are the top 10 health benefits of having sex, whether it is by yourself or with a partner!

     

    #1. Can Improve Your Cardiovascular Health

    One great thing about sex is that it can improve your cardiovascular health by not only lowering your blood pressure but strengthening muscles, burning calories and increasing heart health. Overall, it helps reduce risk of heart disease, stroke and hypertension. (1)

    Individuals with active sex lives tend to exercise more frequently and have better dietary habits than those who are less sexually active. Research shows that physical fitness may also improve sexual performance overall (1). So to support a healthy heart and great sex, remember to exercise regularly.

     

    #2 Burn Calories

    If you are someone that doesn’t like working out at the gym, maybe “working out in the bedroom” might be a better and more fun approach! In a 2013 study, 21 heterosexual couples were asked to wear SenseWear fitness trackers during their lovemaking to determine how many calories were burned. The results concluded that men burn 100 calories during the average sex session (about 25 minutes), while women burn about 69 calories (2). Harvard medical school reported that sex burns about five calories per minute

     

    #3 Reduce Pain

    Believe it or not, sex can help relieve pain. A review of peer‐reviewed literature on the associations between distinct sexual activities and various factors of psychological and physical function found having an orgasm increases blood flow, and releases endorphins and other natural pain-relieving chemicals (3).

    Another study showed how engaging in sexual activity during a headache attack can positively impact headache intensity. The results of the study found: 60 percent reported an improvement during a migraine, 70 percent reported moderate to complete relief during a migraine, 37 percent reported improvement of symptoms in cluster headaches, 91 percent reported moderate to complete relief in cluster headaches (4). So…. in reality the old “oh sorry honey, I have a headache” should maybe be replaced by “Honey, I have a headache, let’s have sex!”

     

    #5. Reduce Risk of Prostate Cancer

    Research shows that there could be relation between regular sex and reduction in prostate cancer. One study found that men who averaged having 4.6 to 7 ejaculations (from sex or on their own) a week were 36% less likely to receive a prostate cancer diagnosis before the age of 70. This is in comparison to men who reported ejaculating 2.3 or fewer times a week on average (5).

     

    #6. Increase Life Expectancy

    For men, sex may even affect their mortality. One study that had a 10-year follow-up reported that men who had frequent orgasms (defined as two or more a week) had a 50 percent lower mortality risk than those who had sex less often (6).

     

    #7. Look Younger

    Research is showing that frequent sexual activity, whether with a partner or alone, can make you look younger. This is partially due to the release of estrogen during sex. Estrogen helps skin stay hydrated by boosting hyaluronic acid. Hyaluronic acid is a clear, gooey substance that is naturally produced by your body. Its main function is to retain water to keep your tissues well lubricated and moist (keeps skin looking young).

    A 1997 study of 3,875 postmenopausal women concluded that estrogen supplementation helped aging women have younger looking skin and also helped maintained skin’s collagen matrix, thickness, elasticity and ability to retain moisture (7).

    Another study found a correlation between frequent sexual activity and looking significantly – up to seven to 12 years – younger (8). 

     

    #8. Improve Memory with Age

    At an older age, sexual activity may affect your well-being and ability to think. Research found that sexually active adults between 50 to 90 years old had better memory. They were also less likely to feel depressed and lonely (9).

    #9 Increase the Bond in a Relationship

    Morning sex can bring you and your partner closer together. How so? Sex produces oxytocin, also known as the “love hormone.” Oxytocin is the chemical in the brain that controls bonding and love. When it’s released during sex, the result is feeling more connected to your partner (10).

     

    #10: Boost Your Immune System

    Reduced stress helps to support a healthy immune system, and sex can be a natural stress reliever due to the endorphins and oxytocin produced. But researchers discovered that sex can support your immunity further by triggering your body’s natural defences against bacteria, viruses, and other germs. So, “get busy” to boost your immune system! (11)

    So, if you needed a few reasons to prioritize sex more often – that wraps up our top 10 health benefits of sex! Which one has you convinced to spend a little more time “in the bedroom”?

    5 Nutrition Strategies for Cancer Prevention

    5 Nutrition Strategies for Cancer Prevention

    Ketogenic Meal

    An estimated 225,800 new cases of cancer and 83,300 deaths from cancer will occur in Canada in 2020. Cancer is the leading cause of death in Canada and is responsible for 30% of all deaths.

    Based on 2015 estimates nearly 1 in 2 Canadians (45% of men and 43% of women) is expected to develop cancer during their lifetime and approximately 1 out of 4 Canadians (26% of men and 23% of women) is expected to die from cancer. (Canada Cancer society)

    Based on research from the New England Medical Journal of 45,000 twins it was identified that 85% of cancers are caused by environmental factors, including diet and lifestyle. Humankind has invented 10 million new chemicals and unwittingly released thousands of these into our environment, many of which are known as carcinogens. In fact, the growth in the incidence of cancer parallels the industrialization and chemicalization of our world, which is why we are likely seeing the ongoing rise of cancer rates over the last century(1) .

    Specific to the impact of nutrition, the World Cancer Research fund indicated that eating the right diet may cut your risk of cancer by up to 40%. The key organs that help to fight off cancer are your liver and your immune system, so nutrition support to help these organs function at their best is important. We also want to help create a terrain within our bodies that is not conducive to cancer growth, which includes having a more alkaline state.

    So, let’s have a look at what dietary changes you can make to help reduce your risk of getting cancer:

    1. Consume at least 7 servings of fruits and vegetables a day

    (ideally organic to reduce chemical exposure).
    You should also include a rainbow of colours to ensure you are consuming a wide-range of cruciferous vegetables daily, such as broccoli, Brussel sprouts, cabbage, cauliflower and kale helps support the liver the key organ in helping to combat cancer.Fruits and vegetables contain antioxidants which extensive research is showing can help treat and prevent cancer. In a scientific review of 206 human and 22 animal studies it was shown that greater fruit and vegetable intake has a protective effect with cancers of the stomach, esophagus, lung, oral cavity, pharaynx, endomedtrium, pancreas and colon (2). We must also consider that cancer thrives in a low-oxygen, acidic environment (Cancer Research Journal 2006) and eating fresh fruits and vegetables, especially dark leafy greens, is great way to help increase the pH levels in the blood which puts the body in a more alkalinize state making it a more difficult environment for cancer cells to grow. Where as grains, coffee and sugars lower pH levels making the body more acidic so these foods should be avoided.

    2. Reduce red meat intake

    This includes beef, pork, lamb and goat and processed meats such as hot dogs, sausages, deli meats. Red meat is acidic to the body which creates an environment conducive to cancer growth. The World Cancer Research Fund recommended if you do eat red meat this should be limited to at most 500 grams a week). One study found that women who ate red meat every day had a 56% increase risk of breast cancer (4). Plus, research shows that people that consume higher amounts of red meat are at greater risk of stomach, pancreatic and breast cancer(3). Red meat consumption in countries that inject growth hormones and other hormones to increase milk supply can increase the risk of hormone-based cancers such as breast and prostate.

    If you are consuming red meat opt for organic, grass-fed beef, lamb or game, as these meats are less inflammatory than their factory-farmed counterparts. Maintaining a focus on lean organic, free-range eggs, poultry and game, wild-caught fish, and vegetable-based proteins is important.

    Processed meats contain N-nitroso compounds (NOCs), which can damage DNA and contribute to cancer development. High cooking temperatures may produce additional carcinogens in meats. You should especially avoid chargrilled meat on the BBQ and frying as this is creates well-known carcinogens and increases the risk of stomach and colorectal cancer. A healthier cooking option is frying foods in a little water as opposed to oils, which often become rancid at high heats.

    3. Avoid sugar.

    Cancer cells usually grow quickly, and multiply at fast rates, which takes a lot of energy – this means they need lots of glucose. Cancer cells thrive on sugar. In fact, individuals with type 2 diabetes have three times the risk of developing cancer. A diet rich in sugary foods and beverages can lead to obesity, which significantly raises your risk of cancer (5). Cancer Research UK reports eating high amounts of sugar over time can cause you to gain weight, and robust scientific evidence shows that being overweight or obese increases the risk of 13 different types of cancer. Obesity is the single biggest preventable cause of cancer after smoking.

    Additionally, sugar is acidic to the body and cancer tends to thrive in acidic environments. Diets high in sugar increase inflammation in your body and may lead to insulin resistance, both of which increase cancer risk (6). A study in over 430,000 people found that added sugar consumption was positively associated with an increased risk of esophageal cancer, pleural cancer and cancer of the small intestine (7).

    4. Limit Alcohol

    Alcohol is one of the top three causes of cancer deaths worldwide. Last year, it is estimated that as many as 10,700 Canadians were diagnosed with cancer linked to their alcohol consumption (Canadian Cancer Society). A survey showed that 60% of Ontario women and 41% of Ontario men exceed the alcohol consumption guidelines recommended by the Canadian Cancer Society.  

    The National Toxicology Program of the US Department of Health and Human Services lists consumption of alcoholic beverages as a known human carcinogen. The evidence indicates that the more alcohol a person drinks—particularly the more alcohol a person drinks regularly over time—the higher his or her risk of developing an alcohol-associated cancer. Both light drinkers (those who have no more than one drink per day) and binge drinkers have an increased risk of some cancers (8-12). 

    Alcohol consumption can increase the risk of mouth and throat, larynx, oesophagus, breast, liver and bowel cancer. The Canadian Cancer Society recommends that women have less than one standard drink per day and men have less than two standard drinks per day.

     

    While there’s no one thing any of us can do (or not do) to ensure with certainty that we don’t develop cancer, there are many diet and lifestyle changes that we can make as individuals in order to give ourselves the best chance possible of a long and healthy life!

    Top 6 Cancer-Preventative Foods

    Top 6 Cancer-Preventative Foods

    Ketogenic Meal

    There is growing research on the power of foods and the impact on preventing, or even addressing, cancer. This is empowering for people who are at risk or who have cancer!

    All of us have “cancerous” cells in our bodies at all times – this is normal. Our bodies are constantly making new cells, and sometimes things go wrong. However, in a healthy body, the number of these cells is small enough that our immune system is able to detect the cancerous cells and destroy them before they have the chance to get out of control. Many of the foods below help to prevent cancer development because they either support the healthy division of new cells (meaning the body makes fewer mistakes), or because they support the immune system in targeting cancer cells, or both!

    Let’s explore our top 6 foods that can help us fight cancer.

    1. Turmeric

    The Indian spice, turmeric, is anti-inflammatory, anti-viral, anti-bacterial, anti-fungal, and can be extremely helpful when it comes to fighting cancer. Studies show that the active compound curcumin, found in turmeric, may help to kill cancer cells and slow tumor growth (1).

    The research on the benefits of curcumin with cancer show that it can help protect against every stage of cancer development including initiation, promotion and progression. Curcumin has been shown to block cancer cells from multiplying, and in killing colon, breast, prostate, and melanoma cancer cells as well as slowing or inhibiting tumor growth (2).

    2009 study found that curcumin can kill many types of cancer cells in multiple ways. Because more than one method is possible, cancer cells are less likely to become curcumin-resistant. Curcumin targets only cancer cells, leaving healthy cells unaffected. This is an important step in potential treatment because chemotherapy drugs kill both healthy cells and cancer cells (3).

    Add some turmeric to your next dinner, take a supplement containing curcumin to experience the benefits of this powerful substance, or make a Golden Milkshake.  Link to recipe

    2. Garlic

    The American Institute of Cancer indicates that there are many ways in which garlic and its compounds may help prevent cancer. Lab studies show that garlic compounds help with DNA repair, slow the growth of cancer cells, decrease inflammation and prevent the formation of carcinogenic substances in the body. A 2019 study further supported the role of garlic in DNA repair in that (at least in the lab) garlic appeared to enhance the expression of tumor suppressor genes.

    Garlic has natural antioxidants and is anti-inflammatory, antibacterial, and antiviral. It contains high levels of sulfur, flavonoids, and selenium all of which are nutrients that support our liver and immune system. Plus, when it is crushed, chopped, or bruised, garlic produces the compound allicin which can help inhibit tumor growth (7).

    Garlic contains allyl sulfur and other compounds that slow or prevent the growth of tumor cells. Allyl sulfur compounds, which occur naturally in garlic and onions, make cells vulnerable to the stress created by products of cell division. Because cancer cells divide very quickly, they generate more stressors than most normal cells. Thus, cancer cells are damaged by the presence of allyl sufur compounds to a much greater extent than normal cells (1).

    After a review of the global research, AICR’s reports found that eating garlic frequently lowers the risk of colorectal cancers and breast cancer, stomach, colon, lung and prostate (2,3,4,5,6).

    Based on the research, eating 2–5 grams (approximately one clove) of fresh garlic per day, or 300 to 1,000 milligrams of garlic extract, reaps benefits.

     3. Green tea

    Green tea is an excellent antioxidant, and studies show the properties of green tea help protect against metastasis of certain kinds of cancer (1). Green tea also contains chemicals called polyphenols that have antioxidant and anti-inflammatory properties. The nutrient EGCG in green tea can help induce cell death in human cancer cells.

    A comprehensive review of observational studies found that women who drank had an approximately 20–30% lower risk of developing breast cancer, one of the most common cancers in women (2). Another study observed that men drinking green tea had a lower risk of advanced prostate cancer (3) and an analysis of 29 studies showed that those drinking green tea were around 42% less likely to develop colorectal cancer (4).

     4. Cruciferous Vegetables

    Cruciferous vegetables include arugula, bok choy, broccoli, Brussels sprouts, cabbage, cauliflower, kale, radish, and turnips.

    All cruciferous vegetables contain glucosinolates, natural substances that break down during chopping, cooking, chewing and digestion into biologically active compounds called isothiocyanates and indoles. In laboratory experiments in rats and mice, these compounds have been found to inhibit cancers of the bladder, breast, colon, liver, lung and stomach. They protect cells from DNA damage by inactivating carcinogens and decreasing inflammation. Plus, they can help inhibit the formation of blood vessels and the migration of tumor cells, two processes that help spread cancer.

    Cruciferous vegetables also contain other protective compounds, including carotenoids, plant pigments that may control abnormal cell growth; vitamin C, which acts as an antioxidant, protecting cells and supporting the immune system; and folate, which may also help to maintain healthy DNA and keep cancer-promoting genes turned off (1).

    One analysis of 35 studies showed that eating more cruciferous vegetables was associated with a lower risk of colorectal and colon cancer (2).

     5. Flax seed

    Lignans are plant compounds that have antioxidant and estrogen properties, both of which can help lower the risk of cancer and improve health (1).

    Some studies have shown that consuming 25 grams of flaxseed a day may reduce tumor growth in breast and prostate cancer. It can also reduce the body’s production of estrogen, so its benefits have been linked to breast cancer prevention. In fact, consuming flaxseed can enhance the effectiveness of tamoxifen, a drug commonly used to prevent breast cancer recurrence (2). 

    The American Institute of Cancer Research reported that in a one month-long trial of about 30 post-menopausal women with newly diagnosed breast cancer, daily flaxseed consumption decreased signs of cancer cell growth. In several studies of healthy women consuming flaxseed daily, estrogen levels decreased or shifted to more of a relatively inactive form, resulting in less estrogen in the form believed to promote breast cancer growth.

    Additionally, according to a Canadian study involving more than 6,000 women, those who eat flax seeds are 18% less likely to develop breast cancer (3). Further studies show benefits with colon, prostate and lung cancer (4,5)

     6. Berries

    The researchers, led by Dr. Minna Rahnasto-Rilla, found that one type of anthocyanin, known as cyanidin, found in wild bilberry, raspberry, and cranberry, appeared to reduce the activity of cancer-causing genes and boost the activity of cancer-stopping genes (1).

    Studies show that several antioxidants in berries, including anthocyanins, ellagic acid, and resveratrol, may reduce cancer risk (2,3,4). Specifically, animal and human studies suggest that berries may protect against cancer of the esophagus, skin, lung, mouth, breast, and colon (5, 6,7,8,9).

    Most berries also contain antioxidants, fiber, and vitamin C which can all support a healthy immune system and liver function which is important to creating a terrain within the body that is not favourable to cancer growth. 

    It’s ideal to consume berries daily, with attention to consuming a variety of different berries. Berries can be put in smoothies, on salads, with plain Greek yoghurt, on oatmeal, or just eaten on their own. Be sure to choose organic to avoid unnecessary exposure to pesticides and other chemicals, which are known carcinogens.
