Natural Immune System Strengthening

Diet Therapy for Immune System

The causes of most chronic diseases are actually biochemical, and while biochemistry is exceedingly complex, its origins are not. The raw materials for our bodies' biochemicals are nutrients, and the quality and quantity of these biochemicals are based on the quality and quantity of their nutritional raw materials. If you think about it, what we are as people-our hands, our hearts, our ability to think-comes from our diet. The machinery that processes these raw materials is based on genetics, but the materials themselves are dietary. We are most definitely what we eat.

Richard P. Huemer, MD and Jack Challem: The Natural Health Guide to Beating the Supergerms

The type and the quantity of food you consume is very important for your health. Food provides the energy to your body. For a healthy immune system, the food should provide all the nutrients that are essential for good health.

Food contains several complex chemicals, micronutrients, vitamins, minerals and enzymes. For example, a small clove of garlic contains more than two hundred different chemicals. We cannot survive without food. Absence of good quality food impairs our health by shortchanging our biochemistry. The right diet can keep you healthy, prevent infection, and minimize the need for medications.

The fact that diet is very important in developing the body's resistance to infection had been recognized for thousands of years. The ancient scriptures of India documented the association between food and health in 5000 B.C. The medieval church records in England recorded the relationship between crop failures and famine and subsequent epidemics.

According to Richard P. Huemer, MD, author of "The Natural Health Guide to Beating the Supergerms," the consequences of a good or bad diet cannot be understated. Dr. Huemer has shown that HIV-positive men with a high intake of vitamins do not develop full-blown AIDS as quickly as the men who have a low intake of vitamins. Further, patients with AIDS require large doses of micronutrients to achieve and maintain normal levels of these nutrients compared to healthy persons.

Granted, HIV and AIDS are extreme examples of immune dysfunction. But, while HIV may pose the greatest microbial challenge to the immune system, every infection poses several challenges including those presented by biological agents introduced by terrorists.

Infection disturbs the nutrient levels in the body(3). Variations in the diet result in ups and downs in immunity.

It is not too late for you to take steps to strengthen your immune system. That is because:


Ninety-eight percent of the atoms in your body are replaced each year.


The bones in your skeleton regenerate every three months.


The cells of your liver are made new every six weeks. You generate a whole new skin once a month.


Your stomach lining is replaced every five days.

So, if you feed yourself with the right "foods," you can influence the regeneration process. You can help your body back to a healthy state that can fight the external attackers and keep it in "good shape."

Guidelines For A Healthy Diet

Here are some recommendations for healthy eating for a healthy immune system.

Eat a Low-Fat, High-Fiber Diet

Reduce your fat intake. A high-fat diet can lead to cancer, cardiovascular diseases, and diabetes. It is not enough to reduce just the fat intake. You must combine it with a high- fiber intake.

A low-fat, high-fiber diet reduces your risk of degenerative diseases and improves your overall health. Soluble fiber helps move food through your digestive system quickly.

Fresh fruits and vegetables and whole grains are good sources of soluble fiber. Another great source for soluble fiber is psyllium husk. Consume at least 25 grams of dietary fiber per day.

Fruits and Vegetables

Eat at least five to seven servings of fruits and vegetables per day. They are important source of vitamins, minerals, fiber, and phytochemicals. Phytochemicals provide disease-protective effects to the body.


Adequate protein intake is important for proper immune functioning. 
Protein deficiency can adversely affect all facets of immune function. If you are suffering from diseases such as cancer and AIDS, you need to supplement your diet with a high-quality protein (e.g., whey protein, soy protein isolate, and egg protein) at a dosage of 0.8 gram per 2.2 pounds body weight. The protein will help prevent the wasting away (cachexia) associated with these conditions.

Drink Plenty of Water

Water is the body's single most important nutrient. Almost all of the body's functions rely on water. It carries nutrients to the cells; carries waste and toxins away from the cells and out of the body; maintains the body's temperature; and provides protection and cushioning for the joints and organs of the body.

We lose water constantly through physiological processes such as sweating, elimination and breathing. This water needs to be replenished. The body does not keep a reserve of water as it does with other nutrients. So, our need for water is continuous.

Experts recommend that a healthy adult should drink one and a half to two quarts of water per day. Sometimes we need more water because of accelerated loss of water due to heat, excessive sweating, diarrhea, etc. When you feel thirsty, drink water.

Oils and Essential Fatty Acids

Cold, pressed, unrefined nut or seed oil like flax seed, walnut or pumpkin seed oils contain the essential fatty acids omega-6 linoleic acid and omega-3 alpha-linolenic acid. Our bodies need essential fatty acids for many important metabolic functions. Take the oil daily on salads or in other dishes. The oils lose the critical nutrients when they are heated; so make sure you consume it cold.

Studies have shown that when your body is deficient in omega-6 linoleic acid, our immune system gets suppressed. The body converts linoleic acid into Prostaglandins. Prostaglandins are hormone-like substances that stimulate immunity.

Cold-water fish oil from salmon and mackerel is another good source for essential fatty acid.

For best results, eat fish and a salad with a dressing of unrefined, cold-pressed sunflower or walnut oils. The fatty acid of the fish helps ensure the conversion of the oil's linoleic acid to Prostaglandins.

Foods To Be Avoided

There are several foods you should avoid. We will describe them later. The most important food that you need to avoid or minimize is sugar.


Sugar contains no nutrients. Excessive sugar intake can deplete your body of several vitamins and minerals. We recommend that you avoid consumption of any refined food or food products.

Dr. Robert McCracken, a UCLA anthropologist, faults refined sugar for some forms of diabetes, heart disease, stroke, schizophrenia, alcoholism, and even possibly some kinds of cancer(2). He noted that members of certain primitive tribes who consume more saturated fats than Americans, have normal blood cholesterol levels and suffer from fewer diseases than Americans. His research showed that the main difference is that they never touch refined sugar.

Sugar can cause or promote fungal infections, tooth decay, skin rashes, mucus production, and intestinal candidiasis. It encourages the growth of a number of bacteria and fungi. Sugar provides a great growth medium for these microorganisms.

A high intake of sugar adversely affects the immune system. Sugar impairs the ability of white blood cells to sweep up and kill bacteria. It also robs the body of key nutrients such as zinc that is vital for the immune function. 
Sugar affects everyone. But it can have serious consequences for children. Many children, who have a high intake of sugar, suffer from recurrent infections, asthma, and eczema.

What makes sugar so bad? The biggest problem with sugar is that it gets absorbed very fast. Sugar rushes through the stomach wall without being digested, stimulating excess secretion of insulin by the pancreas and causing metabolic imbalances.

Ironically, the insulin secreted to deal with refined sugar causes your blood sugar level to fall. This upsets the biochemical balance in the brain that is responsible for the production of fully 25 percent of the adult body's metabolic activity. The result: your brain begins to malfunction.

Dr. Nancy Appleton, author of "Lick the Sugar Habit" gave 59 reasons why sugar ruins our health:

When you contract an infectious disease, one of the first thing you should do, if possible, is to undergo a short fast. This will help improve the immune function by lowering the blood sugar levels. It is particularly effective during the first twenty-four to forty-eight hours of contracting an acute infectious illness. Fasting will significantly increase the ability of white blood cells to destroy microorganisms. Do not extend the fasting for an excessive period, since eventually the leukocytes' energy sources will become depleted.
