Foods that are rich in antioxidants and probiotics can help activate your immune system to help fight infections such as H.pylori that can cause stomach ulcers.

Antioxidants and Flavonoids

Studies have shown that the prevalence of stomach ulcers increases with age. 70% of stomach ulcers is caused by the bacterium Helicobacter pylori, or H. pylori. Most ulcers caused by H. pylori are completely treatable. But untreated stomach ulcers can lead to more serious problems, like internal bleeding and stomach cancer. 

If your stomach ulcer is caused by an H. pylori infection, foods that are rich in antioxidants may be beneficial. Antioxidants found in bright coloured fruits and vegetables can help activate your immune system and help combat a H. pylori infection. Read our latest article to learn more about stomach ulcers.

Flavonoids are a phytonutrient found in certain fruits such as berries which can help protect the stomach lining by defending the lining of the stomach and allowing ulcers to heal. In one laboratory study, extracts of various berries inhibited the growth of H. pylori. (4) Also probiotics found in fermented foods such as kefir can also help. Studies have shown that probiotics may be helpful in wiping out H. pylori. The best bacteria to help do this includes LactobacillusBifidobacterium, and Saccharomyces.

5 Steps To Support Your Immune System

5 Steps To Support Your Immune System

Supporting the Immune System Koru Nutrition

You aren’t alone right now in trying to find ways to keep you and your family healthy and your immune systems strong. Individuals and families have been stocking up on their vitamin C and other immune boosting supplements. This is a great step, but there are many other things that you can be doing , or not doing, to optimize your immunity.

5 Steps To Support Your Immune System:

#1. Reduce Sugar Consumption

Are you like most folks? Have you found that while in social isolation, you’re tending to over indulge in certain foods? In particular, comfort foods such as chocolate, ice cream, and sweets? Maybe as you search for things to help keep yourself or the kids entertained, you’re baking more frequently, and eating the results?

Although these foods may feel comforting in the moment, and baking can help ease boredom, sugar has a detrimental effect on the immune system.

Sugar can suppress the immune system (by altering the function of specific immune cells, called neutrophils) for up to 5 hours after ingestion. (Sanchez A. et al, 1973) Because the effect lasts for many hours, if you eat sweets several times a day, your immune system may be perpetually operating at a distinct disadvantage (1). In contrast, the ingestion of complex carbohydrates, or starches, has no effect on the immune system.

Sugar triggers low-grade inflammation in the body and inflammation is also an immune suppressant.

Nate Favini, medical lead at Forward (3), reported that it would be misleading to say that we fully understand the relationship between sugar and our immune system. “What we do know is that diabetes appears to be common in people confirmed to have COVID-19,” he noted. “This suggests that having higher levels of sugars in your blood could make it easier to contract COVID-19.”

Studies have found that excessive amounts of sugar, or glucose, in the body can inhibit the absorption of Vitamin C (2). Vitamin C is extremely important for boosting the immune system and fighting off infections. In the 1970s, researchers established that Vitamin C has a similar structure to sugar and therefore can compete for absorption.

As an antioxidant, it is the job of Vitamin C to neutralize free radicals. By consuming sugar with Vitamin C, you are introducing more free radicals that Vitamin C may sacrifice itself to neutralize instead of being available to support your immune system.

#2. Reduce Alcohol Consumption

The Cleveland clinic reported that If you drink every day, or almost every day it can weaken the immune system and make the body more susceptible to infections, such as colds, flu or other illnesses more frequently than people who don’t drink. Many people have increased their alcohol consumption while being restricted to stay at home with social distancing protocols, which is not good for immunity!

Alcohol alters the makeup of your gut microbiome, which is the home to trillions of microorganisms performing several crucial roles for your health, including supporting your immune system. It seems that drinking alcohol may also damage the immune cells that line the intestines, which serve as the first line of defense against bacteria and viruses. By damaging those cells in your intestines, it can make it easier for pathogens to cross into your bloodstream (4).

Plus, excessive drinking reduces the number and function of three important kinds of cells in your immune system–macrophages, T and C cells. Macrophages are the first line of defense against disease. They gobble up anything that’s not supposed to be there, including cancerous cells, and they sound the alarm if pathogens are present. T cells are antibodies to specific pathogens. They are the reason vaccines work and why you can’t get chicken pox twice. Your T cells already know how to kill those specific kinds of viruses. B cells are white blood cells that secrete cytokines that attack bacteria. When B and T cells are suppressed, your immune system is less efficient at identifying and destroying invading pathogens.


#3. Manage Stress

Unfortunately, at this time, people have been losing jobs, are financially strained, trapped in a home or apartment with either no time for themselves or too much time to themselves, wondering if their businesses will last, or trying to juggle home schooling the kids with work.

In short spurts, our stress hormone, cortisol, can boost immunity by limiting inflammation. But over time, your body can get used to having too much cortisol in your blood and this opens the door for more inflammation. This can weaken your immune system, leaving you more vulnerable to viral infections and frequent illnesses.

In addition, stress decreases the body’s lymphocytes — the white blood cells that help fight off infection. The lower your lymphocyte level, the more at risk you are for viruses.

The brain and the immune system are in constant communication in this delicate balance that can be disrupted by any kind of physical or emotional stress. Some experts claim that stress is responsible for as much as 90% of all illnesses and diseases.

#4. Get a Good Night’s Sleep

The Mayo Clinic reported that studies show that people who don’t get quality sleep or enough sleep are more likely to get sick after being exposed to a virus. Lack of sleep can also affect how fast you recover if you do get sick.

During sleep, your immune system releases proteins called cytokines, some of which help promote sleep. Certain cytokines need to increase when you have an infection or inflammation, or when you’re under stress. Sleep deprivation may decrease production of these protective cytokines. In addition, infection-fighting antibodies and cells are reduced during periods when you don’t get enough sleep.

How much sleep do you need to bolster your immune system? The optimal amount of sleep for most adults is 7.5-9 hours of good sleep each night, while teenagers need 9-10 hours of sleep, and school-aged children may need 10 or more hours of sleep per day.

#5. Not Eating Enough Fresh Fruit and Vegetables

Our immune system relies on a number of nutrients to help it function properly and work at its optimal level. Key nutrients include vitamin C, iron, Vitamin D, folate, Vitamin A, selenium and zinc. It is difficult to intake adequate amounts of these nutrients from processed foods, but you will get them from fresh fruits and vegetables. Unfortunately, many North Americans are not getting enough fruits and vegetables into heir diet, nor are they consuming enough variety.

Canadian Community Health Survey (CCHS) indicate 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 (FV) daily. Health Canada recommends a minimum of 7-8 servings of fruits and vegetables a day for adults, and this is rarely achieved.

Unfortunately, with high stress, poor sleep, diseases and illnesses our body’s demand for nutrients becomes higher. This would only be compounded by an already compromised diet with processed foods, pizzas, and frozen dinners; consumption of sugar-laden foods and beverages; and limited intake of fresh fruits and vegetables in the diet. These societal dietary habits put us at huge risk of nutrient deficiencies, and subsequently a compromised immune system, which impacts our ability to help protect ourselves against viruses and infection.

If you are struggling to get enough fruits and vegetables into your diet you can explore supplementing with a whole food supplement which contains 30 fruits and vegetables. Separate studies were conducted on healthcare professionals with direct patient contact, young law school students, an elderly population, and athletic men. The combined results of those studies show that a combination of orchard, vegetable and berry capsules, “Reduces the severity of upper respiratory challenges, reduces missed work days, and increases the number and activity of immune cells circulating in the body”. British Journal of Nutrition (2011) Journal of Nutrition (2007) Medicine & Science in Sports & Exercise (2006) Journal of Nutrition (2006) Integrative Medicine (1999).

We’re all doing our best right now to protect ourselves, our family, and our communities from illness. Reducing sugar consumption, limiting alcohol intake, practicing stress management techniques, getting adequate sleep, and ensuring an adequate intake of fresh fruits and vegetables are five more ways that you can help support your immune system!

    Supporting the Immune System with Vitamin C

    Supporting the Immune System with Vitamin C

    Supporting the Immune System Koru Nutrition

    The world is going through unprecedented times at the moment. Supporting a healthy immune system has never been so crucial for our health and the health of our families. At Koru Nutrition we want to make sure that you have the right information so you can take the steps needed to build a healthy immune system and help protect you and your family.

    Influenza, commonly known as “the flu”, is an infectious disease caused by an influenza virus. Symptoms can be mild to severe. The most common symptoms include: a high fever, runny nose, sore throat, muscle pains, headache, coughing, and feeling tired. These symptoms typically begin two days after exposure to the virus and last about a week. The cough, however, may last for more than two weeks. Right now, we are living in uncertain times with the immergence of the novel coronavirus, COVID-19. Although part of the cold and flu family, the human race has never been exposed to this virus before.

    So is there anything we do to protect ourselves?

    The Under-Rated Power of Vitamin C

    Health food stores and drugstores have been running out of various immune-supportive supplements as people attempt to strengthen and enhance their immunity. Vitamin C is one supplement that has been in high demand.

    But does vitamin C really protect us?

    Vitamin C is found in high concentrations in our white blood cells, but is rapidly depleted during infections resulting in reduced immunity (5,6). Vitamin C helps us to upregulate our immune system, and the scientific literature has extensive research on the ability of vitamin C to support the body in recovery from a variety of viruses (4, 5, 7, 8, 9).

    A vitamin C deficiency results in a weakened immune system and susceptibility to colds and other infections. Since the lining of the respiratory tract also depends heavily on the protection of vitamin C, respiratory infection and other lung-related conditions may also be a symptom of inadequate vitamin C intake(10).

    Research shows that vitamin C in  therapeutic doses  can be very effective at preventing and addressing the common influenza virus, sometimes even after serious complications such as encephalitis have arisen along with many other viral syndromes (4). In spite of this information, vitamin C is still not routinely utilized against this infectious disease, and none of the various forms of vitamin C are included in the formularies of nearly any US hospitals.

    One study on individuals that had cold/flu-like symptoms split participants into 2 groups. The control population were treated with pain relievers and decongestants, whereas those in the test population were treated with hourly doses of 1000 mg of Vitamin C for the first 6 hours and then 3 times daily thereafter. Overall, reported flu and cold symptoms in the group that was administered vitamin C decreased by 85% compared with the control group. (1)

    In the evaluation of vitamin C, administration of extra therapeutic doses at the onset of cold/flu symptoms has found to help reduce illness duration, shorten the time of confinement indoors and relieve the symptoms associated with it, including chest pain (2).

    Unfortunately, because the novel coronavirus has never been seen before, there is little research to date about the impact of vitamin C specifically on the COVID-19 virus. However, because vitamin C has shown success in treating many other viral infections and has a very low risk-profile, it may be one more tool you and your family can use – in addition to social distancing, frequent handwashing, and wearing a facemask and gloves in public – to help protect yourselves.


    Currently, for the immune benefits. Vitamin C supplementation is very safe. There is no documented toxicity level for vitamin C because it is a water-soluble vitamin, which means it is flushed out of the body relatively quickly. Vitamin C is also easily lost with stress, and as mentioned above, is rapidly lost when a person is sick or has an infection.

    Because vitamin C has a laxative effect at higher doses, often health professionals recommending individualized high-doses for their clients will suggest taking it only to bowel tolerance. Vitamin C is best taken with meals to improve absorption.


    Foods High in Vitamin C

    Having a diet high in fruits and vegetables is a great step to not only increase your vitamin C intake, but also your intake of many other immune-supportive antioxidants and nutrients. If you are unable to supplement, or simply want to increase your intake, the chart below outlines some foods that are high in vitamin C. However, if you do have flu-like symptoms vitamin C supplementation is highly recommended.

    Food Amount (mg) Daily value (DV) %
    Bell Peppers (1 cup) 174.8 291%
    Parsley (2 tablespoons) 10 16.6%
    Broccoli (1 cup) 123.4 205.7%
    Strawberries (1 cup) 81.7 136.1%
    Tomatoes (1 cup) 34.4 57.3%
    Lemon juice (¼ cup) 28.1 46.8%
    Oranges (1 fruit) 69.7 116.2%
    Kale (1 cup) 53.3 88.8%
