Updated on January 7, 2019

Marisa is an educator and researcher. She has a great interest in healthy foods and health journalism.

Antioxidants help the body combat disease. Studies have shown that a diet rich in a variety of antioxidants may help lengthen lifespan. A review of mice on a diet rich in catalase, an antioxidant-rich enzyme, had an 18% increase in lifespan.

What are antioxidants?

First, let's look at oxidation.

  • Oxidation is a chemical reaction.
  • Oxidation produces free radicals.
  • Free radicals damage cells.
  • The damaged cells promote unhealthy tissues, may lead to cancer, induce disorders and can speed the effects of aging.


  • Antioxidants can slow and at times completely stop oxidation.


  • Antioxidants are used in patients suffering from brain injuries, including strokes — the antioxidants aid in preventing additional oxidative stress on brain tissue.
  • Antioxidant research has provided positive outcomes in the treatment and potential prevention of Alzheimer's and Parkinson's Disease.
  • Blueberries, for example, have been found to improve our health in a variety of ways significantly. Specifically with cognition, retinal health, cardiac health, and weight control.

What are antioxidants? Antioxidants are a variety of vitamins, minerals, enzymes and general nutrients found in plant and some animal food products.

Some antioxidants include:

  • Vitamin C
  • Vitamin E
  • Beta-carotene or Carotenoids: lycopene, carotenes, lutein
  • Polyphenlic: resveratrol, flavenoids
  • Selenium
  • Catechins

Aging begins when we are born. Although we cannot turn back the hands of time to our youth, we can improve our lives through a healthy lifestyle.

Diet and Aging

Aging, of course, happens daily. Aside from the changes found in our physical appearance: gray hair, yellowing teeth, wrinkled skin, vision problems and brittle bones, the body also begins to lose useful functions in the brain and heart. As we age, we tend to develop and become more susceptible to arthritis, osteoporosis, memory loss, heart disease, fluctuations of blood pressure and even cancer. These problems together with a broader waistline can induce a diagnosis of metabolic syndrome.

The years of an unhealthy diet can begin to take a toll, and as our body loses resiliency, we start to see cases of inflammation and a weakened immune system.

Before you throw your hands up in the air and succumb to unhealthy aging, there are some alternatives. Although were are not granted the time traveling luxury of starting all over again, we can begin each day with a healthy lifestyle and diet.

Antioxidants: Foods or Supplements?

We can all benefit from taking a multivitamin. However, a diet rich in all of our necessary nutrients is best. Although it is not always easy to attain all of the nutrients, we can begin to include these antioxidant-rich foods in our diet and supplement as needed. Always consult a physician about your consumption of supplements.

Incidentally, the American Heart Association does not recommend using antioxidant supplements. Instead, the AHA suggests a diet rich in a variety of healthy foods found in the primary food groups.

If mineral deficiencies are a concern, you may want to look into the following information on the effects of mineral deficiencies.

These include:

  • Potassium Deficiency: Potassium Rich Foods
  • Magnesium Deficiency: Magnesium Rich Foods
  • Calcium Deficiency: Calcium-Rich Foods

Foods with antioxidants

Note, some foods may be on more than one list due to the variety of properties they hold. Here is a partial list of many foods containing antioxidants.

Vitamin C: citrus, blueberries, elderberry, mixed berries, green leafy vegetables, guava, kiwi, tomatoes, peppers, and broccoli.

Flavonoids (anthocyanins, resveratrol, and catechins): apples, blueberries, cherries, cranberries, elderberry, grapes, raspberries, and strawberries. Green teas and matcha provide catechins.

Vitamin E: A variety of nuts and seeds, almonds, peanuts, and walnuts. Avocados and green leafy vegetables are also rich in vitamin E. Don't forget olives and wheat germ.

Beta-carotene: cantaloupe, carrots, mangoes, papaya, pumpkin, spinach, squash, and sweet potatoes. These are great for skin care too!

Carotenoids (lutein and lycopene): carrots, tomatoes, kale, passion fruit, and spinach.

Selenium: Usually found in a variety of proteins. Consider lean meats when selecting beef, pork, poultry or seafood. Selenium is in mushrooms and whole grains.

Antioxidants and Aging

Green Tea and Longevity

The health benefits of green tea can significantly improve life expectancy. Green tea has powerful cancer-fighting antioxidants and ingredients, which will enhance memory, cognition, cardiovascular health, and brain function.


Stress is known to affect the aging process negatively. Consider adding relaxation techniques and moderate exercise to your lifestyle. It will improve serotonin levels, help you sleep better and develop your overall feelings of well being. Plus, stress can age your appearance. Lighten those pesky wrinkles with a radiant smile and a breath of fresh air.

Suggested Foods for Reducing the Signs of Aging

Here is a general grouping of foods we should include in our daily diets.

Water: Necessary for hydration of the body and aids in flushing away toxins. Regular water consumption also improves complexion and radiance.

Yogurt: Yogurt is an excellent probiotic. Probiotics help maintain healthy digestion and adds beneficial bacteria to the digestive tract. Yogurt also provides the body with calcium.

Whole Grains: Fiber is a vital diet element. It provides bulk to stave off hunger, improves digestion, helps lower cholesterol and aids in controlling blood sugar.

Legumes: A variety of beans are a great source of protein, magnesium, and potassium. All of these are low in cholesterol and contain blood pressure lowering nutrients. Legumes are also rich in fiber and low in calories.

Nuts: Nuts are the perfect healthy snack or salad topper. They provide vitamin B and selenium. Plus, the fats found in nuts aid in maintaining skin structure and resiliency. So if sagging skin s driving you nuts, why not eat them instead? Use caution though; nuts are high in calories.

Fish and Flax: Fish and flax are both rich in omega-3. These essential fatty acids aid in mental, retinal and cardiac health. Fish should be oily cold water fish.
