Foods that Boost Immune System Function


Before we delve into foods that boost immune system function it's important to understand that nutritional biochemistry is very complicated and complex at best.

All nutrients require other nutrients as co-factors, either for activation or function from each of the nutrient categories, vitamins, minerals, and amino acids. For activation, all the nutrients discussed above (vitamins, minerals, and amino acids) require enzymes, and for function, essential fatty acids are also vital.

For example, zinc cannot function without vitamin B6, nor can some enzymes be made without it. The mineral calcium needs vitamin D to be absorbed, and vitamin E interacts with other nutrients such as beta carotene, vitamin C, vitamin A and selenium to help keep your body functioning at its best.

In short, no nutrient is an island all unto itself. As such, eating a healthy diet is essential in you're your quest for foods that boost immune system function.

For optimal immune system health and function, a healthy diet is one that is rich in whole, natural foods, such as fruits, vegetables, grains, beans, seeds, and nuts. It should also contain adequate but not excessive amounts of protein.

In addition, a diet that is low in fat and refined sugars is vital for promoting a strong healthy immune system.

Indeed, we believe eating a healthy diet is the best method in your search for foods that boost immune system function.

Can a healthy diet alone provide you with all the nutrients needed to maintain optimal health and a healthy immune system?

Many naturopath physicians as well as many others feel that it is essential for optimal health that you add to your healthy diet at the very least antioxidant supplements as well as taking a high quality multivitamin and mineral supplement.

2. The nutritional value of our fruits and vegetable has declined significantly due to modern day farming practices.

3. Mass production of our fruits and vegetables has robbed us of even more essential nutrients because premature harvesting does not allow them to reach their natural peak of nutrition. Nowadays, our fruits and vegetables are often picked before they are ripe and allowed to ripen in transit.

4. Experts say that are body cells contains 400 new toxins that didn't exist 45 years ago!

Given these harsh challenges, we believe that you should consider adding a comprehensive multivitamin and mineral supplement to you're daily regimen.

"Testing by shows that one in four supplements in the United States lacks the promised ingredients or has other serious problems."
