As we head into the tail end of summer—whether you’re soaking up the sun by the pool or enjoying a Labor Day cookout—your body is fighting an invisible battle against little molecules called free radicals. These unstable, highly reactive molecules are produced naturally in the body, but they’re also triggered by things like alcohol, tobacco smoke, and too much sun exposure.
In small amounts, free radicals are part of your body’s defense system. But in excess, they can damage cells and may play a role in cancer, heart disease, stroke, arthritis, vision loss, and even brain conditions like Parkinson’s or Alzheimer’s disease.
Here’s the good news: your diet can help. Antioxidants are compounds that protect against and neutralize free radicals. While they don’t slow down aging or guarantee longevity, they may reduce the risk of disease and support healthy aging. The best way to get antioxidants is through a balanced diet full of plant foods, rather than supplements.
Here are some common antioxidants and where to find them:
- Vitamin C – Supports the immune system and helps protect against cell damage. Found in citrus fruits, kiwis, mangoes, bell peppers, broccoli, spinach, and berries.
- Vitamin E – Helps limit free-radical production. Found in plant oils (sunflower, safflower, corn, soybean), avocados, whole grains, nuts, and seeds.
- Carotenoids (beta-carotene, lycopene, lutein) – Linked to cancer protection and eye health. Found in colorful fruits and veggies like sweet potatoes, carrots, pumpkins, tomatoes, watermelon, apricots, and leafy greens.
- Flavonoids (anthocyanins, catechins) – Support heart and brain health. Found in onions, garlic, leafy greens, green tea, and cocoa. (Red wine contains flavonoids too, but alcohol itself creates free radicals, so it’s not the best source.)
You don’t need to overhaul your diet to get more antioxidants—just focus on variety. A colorful plate filled with fruits, vegetables, nuts, and whole grains is one of the simplest ways to give your body the support it needs for healthy aging. Small, consistent choices today can add up to a stronger, healthier tomorrow.
