Our immune system is a complex army of warriors with different “weapons” patrolling the body to hunt down and kill invading bacteria and viruses. Unfortunately, as we age, it does too, and becomes weaker along with muscles, eyes, and everything else. Fortunately, there are immune boosters in your refrigerator called antioxidants that can keep your disease fighting warriors stronger for longer.
Antioxidants to the Rescue
What exactly is an antioxidant? Our bodies naturally produce free radicals as a result of exposure to environmental toxins like too much sunlight, cigarette smoke, radiation and even some prescription drugs. You also produce free radicals along with inflammation in the body when you exercise, become overly stressed, and as you age. Because free radical molecules are missing an electron, they seek out and capture electrons from other molecules turning them into free radicals, a process known as oxidation.
Antioxidants generously lend molecules missing an electron one of theirs without becoming free radicals themselves, thus halting the destructive chain reaction in the body. Left unchecked free radicals disrupt DNA and cause your cells to become weaker and weaker until they die. They are tiny superhero defenders of youth and vitality.
Antioxidants for What Ails You
Our immune system cells are as susceptible to free radical damage as any other kind of cell, and we need a steady supply to stay healthy. Incorporating antioxidants into your diet helps as an immune booster and assists your immune system to produce strong B and T lymphocytes, phagocytes and neutrophils.
Several of our organs play a key role in the immune system and also need to be constantly generating strong healthy cells to replace those lost to free radicals. Make sure you ingest plenty of antioxidants to boost your immune system to help stave off disease, and even slow down the aging process.

Fortunately, it’s easy to fill up on antioxidants. They are found in many of the healthiest and delicious foods available to us in abundance. Certain antioxidants are not being produced by the body, so you need to get them from you diet. They are:
Resveratrol – found in grapes, many vegetables, dark chocolate (cocoa) and wine. It also helps lower blood pressure, improves circulation, and reduces inflammation in the body.
Carotenoids- give certain foods their bright color like tomatoes (lycopene) and carrots (beta-carotene). They are converted to vitamin A, a powerful antioxidant, in the body.
Xanthophyll – found in kiwis, maize (a kind of corn), grapes, squash and oranges.
Astaxanthin – a marine carotenoid that offers protection from ultraviolet radiation. It also has been found to slow down macular degeneration, reduce your risk of Alzheimer’s disease and dementia, several types of cancer and is a powerful immune booster.
Best Sources of Antioxidants
Healthy and delicious foods can supply most of your antioxidant needs. You might also benefit from an antioxidant supplement to make sure you get adequate amounts daily. Be sure to add to your diet:
- Herbs and spices
- Green tea
- Fruits and vegetables
Fresh, organic produce and tea are your healthiest options, but even frozen foods offer some beneficial immune booster antioxidants.
