Antibodies are the body’s defense system; these cells fight sickness and infection wherever they are needed. When a person has a low level of antibodies, it is usually indicative of a medical problem, an infection or a recent treatment, such as chemotherapy. Increasing the level of antibodies in the body can help a person to feel better and get sick less often. There are a few medications that can be taken to increase antibodies, but eating the right foods can have the same effect without the side effects.

Oranges are one of the healthiest foods to eat in order to increase antibodies. Dr. Bill Sears, a physician and professor at the University of California at Irvine states that the high level of vitamin C in oranges increases the production of antibodies in the body and actually stops viruses from entering the body. This may be the reason many people take vitamin C to get over a cold faster. Though it can be taken in a supplement form, it’s better to get vitamin C from oranges because they have other health benefits, including antioxidants and fiber.


The mineral zinc, which is found in turkey meat, can increase antibodies in the body and enhance the ability of the body to fight off infections, according to Dr. Bill Sears. He states on his website that the average adult only needs 15 to 25 mg of zinc every day to keep antibodies high, while three ounces of dark turkey meat has about 3.8 mg. Light meat turkey still contains zinc, but people who need to increase antibodies may want to choose dark meat instead, as it has more zinc.


Garlic can be used in many different ways, not just on pasta. Garlic adds flavor to soups and stews and can even be grilled and eaten raw, a little bit at a time. The reason garlic is so healthy is that it stimulates the body to multiply its own antibodies and also makes them stronger, according to Dr. Bill Sears. Garlic has additional health benefits like protecting against certain types of cancer.


According to the World’s Healthiest Foods website, salmon can help boost antibody levels in two ways. Salmon is rich in dietary protein, which helps to stimulate the immune system and healing in the body. Dr. Bill Sears also states that the omega 3 fatty acids found in salmon can prevent the body from getting infections by increasing antibodies.
