Foods to Boost Immune System Function


Foods to Boost Immune System Function …

The immune system has an extremely big responsibility in the body. However, its prime function is to protect the body from infection, viruses, bacteria, and the development of illness and diseases.

In order to achieve a strong immune system requires good nutrition, exercise, and stress management. In addition, a health-promoting lifestyle such as drinking at least eight-8 ounce glasses of clean, pure water a day is necessary.

Water has many vital functions and among them is to transport nutrients and oxygen to our body cells. It also detoxifies the body.

A health-promoting lifestyle also includes not smoking, maintaining a healthy body weight, getting enough sleep, and not consuming excessive amounts of alcohol.

Moreover, experts state that emotional state, environmental toxins, pollution, and excessive use of antibiotics are also factors that affect the immune system.

About Foods to Boost Immune System Function

The first step to ensure your immune system gains the strength it needs to fight the continuous onslaught of foreign invaders involves obtaining all nutrients, which means eating a healthy diet.

In fact, the most frequent cause of a depressed immune system is a nutrient deficiency. Studies have shown that even a deficiency in just one nutrient can profoundly impair the immune system.

A healthy diet is one that is rich in natural foods, such as fruits, vegetables, whole grains, legumes, seeds and nuts. It should also contain an average, 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.

One question that is often asked is do I need to take nutritional supplements if I eat a healthy diet?

We believe that due to the many harsh challenges the immune system is faced with, it needs all the nutritional support it can get. Listed below are some of them.

1. Americans struggle daily trying to consume the daily recommended allowances on fruits and vegetables.

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 proclaim that are body cells contains 400 new toxins that didn't exist 45 years ago!

Now, let's take a look at some of the best immune enhancing nutrients...

Foods to Boost Immune System Function

Beta Carotene

Beta Carotene – Beta Carotene is a compound produced by plants and is converted by the body into vitamin A. Beta Carotene harbors potent antioxidant properties that fight the continuous onslaught of free radicals, which are highly reactive substances that attack and damage cells and, as such, it could lead to premature aging and disease. This compound is noted to stimulate and enhance many immune system processes.

Beta carotene foods to boost immune system:

The richest food sources of beta carotene include pumpkin, sweet potato, carrots, cooked greens, apricots, sweet peppers, kale, turnip greens, broccoli, mango, and squash varieties. The greater the intensity of the color of the fruit or vegetable, the more beta carotene it contains.

Vitamin C

Vitamin C - Vitamin C is thought to boost the immune system by stimulating the production of white blood cells (lymphocytes) and antibodies. In addition, it enhances phagocytes (immune system cells). These actions play a role in fighting infection, protecting against disease-causing organisms, and destroying bacteria and other foreign invaders.

This vitamin is also high in many citrus fruit drinks.

"Thus far, vitamin E has been shown to protect against approximately eighty diseases."

Vegetable oils such as wheat germ oil, sunflower oil, safflower oil, corn oil, and soybean oil are one of the richest sources of vitamin E, followed by nuts and seeds.

Dark, green leafy vegetables are also good food sources of vitamin E, though not as significant as vegetable oils and nuts. When is comes to vegetables - the sweet potato is jammed-packed with vitamin E.

Tips on Selecting Supplements

Make sure that your supplement is produced at a pharmaceutical GMP facility. Such places adhere to the highest manufacturing standards. Dietary supplements are not strictly regulated in the U.S. and, as such, manufacturers do not have to guarantee the safety, effectiveness, or even the true content of their products.

Although supplements should be labeled properly, many aren't, so what's stated on the label may not be in the container. The potency or purity may be inconsistent or misrepresented. Some products tested also contained very harmful contaminates! In fact, according to, the leading provider of independent test results states:

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

This is why it's crucial that you only purchase your supplements from pharmaceutical GMP (Good Manufacturing Practice) compliant facilities. These facilities follow the exact same rigorous standards that pharmaceutical prescription medications must adhere to - thus - it ensures stringent requirements.
