Flu Going around? No problem, cultured foods got you covered.
Viruses, yuck . . . my family used to get them a lot. Colds, flus, you name it, we got it. But so did everybody else I knew. It’s normal, right? Well, it’s actually not. Every year at Christmas we would go to my mom’s in Virginia and somebody would inevitably get sick, and then it would spread down through the family. Happened every year and I never knew why until now. Now we rarely, if ever, get sick. And if we do, it feels like the world is coming to an end because we are all so accustomed to being well. It’s supposed to be this way, and once you feel the freedom that comes with not worrying about getting sick, it feels like the chains have fallen off and you are free. Flu shots? Forget about it! I don’t need them. My immune system’s got it covered, and I’m good to go.
Your gut is responsible 80% of your immune system
Boosting your immune system
Here’s where your microbes come in
White blood cells destroy germs as soon as they detect them. However, if a viral infection begins to take hold, they fight back using a more powerful defense with T and B cells. Antibodies are special proteins made by B cells. They bind to a virus to stop it from replicating, and also label viruses so that other blood cells know to destroy them. T cells have different roles to play. Some act as warning bells that raise the alarm when they detect invading viruses. Here’s where your microbes come in . . . certain good bacteria in the gut influence the strength of the immune system by increasing the number of T cells. There are two kinds of T cells: killers and helpers. Killer T cells find and destroy infected cells that have been turned into viruses making communities. Helper T cells don’t fight invaders; instead, they are like a military intelligence system. When a helper T cell sends out a chemical message, its matched killer T cell is alerted that a virus is present and seeks to destroy it. Having lots and lots of good bacteria in the gut increases T cell production and keeps communication among all the cells functioning at optimum levels. Signals from these beneficial microbes are essential for keeping the immune system strong so it can seek and destroy a virus or infection.
Vitamins increase when you ferment foods
On a daily basis, our body uses antioxidant vitamins to boost the immune system. One of the most important antioxidants for this is vitamin C (sometimes known as ascorbic acid). Studies have shown that vitamin C helps reduce cardiovascular disease, coronary heart disease, stroke; and improves prenatal health problems, eye disease, and even skin wrinkling. We don’t have the ability to make this special vitamin in our bodies, so we must obtain vitamin C from the diet. One of the best ways to do this is through cultured foods and especially cultured vegetables. Lactic acid fermentation increases the micronutrient profile of foods. Not only does vitamin C increase when you ferment foods, but many other vitamins too such as A and B vitamins are also increased. 1 All of the essential nutrients boost our body’s ability to fight infections and invaders and keep our adrenals running at optimal levels.
Sugar lowers your immune system by 75%
Let’s say you decide to have a sugary treat. Maybe you decide to have something like a big piece of cake, or some cookies, or a large glass of soda. Any of these would be enough to get your blood sugar to rise. As your blood sugar starts to rise from the sugar and gets to 120 units or above, the white blood cells start to lose their ability to absorb and fight infections.
Your cells think sugar is vitamin C
Vitamin C is used by white blood cells to engulf and absorb viruses and harmful bacteria. White blood cells need to contain 50 times the concentration of vitamin C as would normally be found in the blood around it. Sugar or glucose has a very similar chemical structure to vitamin C; so when you eat sugar, your cells hungrily take in the sugar thinking it is vitamin C. The 50% concentration of vitamin C in your cells starts to drop and your immune system’s ability to fight a virus is reduced by 75%. It can take four to six hours for the vitamin C concentration in the white blood cells to go back to the normal concentration and to be able to function at the highest level again. So it’s not a great idea, and especially if you’re sick, to eat any kind of sugar, because the white blood cells can’t get past the sugar to do their job.
Cultured foods boost your immune system
