Do Any Foods Contain Immunoglobulin?

Immunoglobulins are antibodies that are the immune system's response to foreign bacteria and viruses. These proteins are found in your blood and help protect your body against cancer cell growth and other conditions. People who lack antibodies may develop an immunoglobulin deficiency syndrome. Since immunoglobulins are made by white blood cells in the body, there are technically not foods that "contain" them; however, there are certain foods you can eat that can help you maintain a healthy immune system, which will make you more likely to have a healthy level of immunoglobulins in your body.

Fruits and Vegetables

Fruits and vegetables are among to best food to eat to help protect your immune system, and build up the level of immunoglobulins in your body. Diets that are high in fruits and vegetables improve immune system functioning. Choose fruits such as apples, pears, raspberries, blueberries, bananas, avocados, peaches and citrus fruits. Choose vegetables like spinach, tomatoes, broccoli, cauliflower, okra, onions, carrots and kale.

Whole grains can also help you maintain a healthy immune system, which can make you more likely to have a healthy level of immunoglobulins. A diet that improves immune-system function includes whole grains such as whole wheat and whole grain bread and cereal; brown rice; whole wheat pasta; barley; orzo; quinoa; and millet. It's important to understand the distinction between a "whole grain" and a "refined grain." Refined grains are those that are milled and stripped of many of their nutritional benefits. White bread, white flour, and white pasta are examples of refined grains. Whole grains, on the other hand, are minimally processed, and still contain most of their key vitamins and nutrients.


Several nutritional supplements may help build the immune system, leading to a healthy level of immunoglobulins. Some of these supplements are garlic, fatty acids like flax seed oils and fish oils, sea vegetables like kelp, zinc, and vitamins A and C, which are antioxidants that help increase immune function.

Certain drinks can help increase your immunoglobulin levels too. Drinks made from green tea and barley can help cleanse your body by providing chlorophyll and other vital nutrients that can repair the tissues in your body. There are some drinks, on the other hand, that can have the opposite effect. Alcohol, coffee and other caffeinated drinks are examples of these.
