Finding Fruits High in Antioxidants

It is popularly known that fruits are a healthy food option, but the specific reasons fruits are good for us are perhaps a little vague to most people. Almost all fruits are high in various vitamins and minerals that our bodies need for energy, effective immune function, and the repair of damaged cells and tissues. Yet there is another category of elements that many fruits contain that have a different purpose: antioxidants. The word may even be familiar to many consumers, but how do antioxidants help us, and what are the best sources of antioxidants?   

What Are Antioxidants?   

In the simplest terms, an antioxidant is any chemical compound that inhibits oxidation, a type of chemical reaction in which a molecule loses electrons. While that doesn’t necessarily seem like a bad thing, oxidation can cause the creation of particles called free radicals; these particles have the potential to damage cells, including the cell membranes and our DNA. This damage happens at the molecular level as the free radicals “steal” electrons from other molecules. Antioxidants, then, prevent this process from happening by essentially giving up their own electrons. 

In the absence of sufficient levels of antioxidants, the body can experience what is known as oxidative stress. This condition is defined as the imbalance between the production of free radicals and the introduction of antioxidants, either through dietary sources or synthesis. When oxidative stress is present in the body, the extra free radicals can cause a wide variety of negative effects in different body systems. This is primarily because changes to the number of electrons in a substance can alter its function in deleterious ways. Below are some examples of conditions that can be caused or worsened by free radicals: 

  • cardiovascular disease brought on by LDL cholesterol buildup in arteries
  • heart disease 
  • high blood pressure
  • numerous types of cancer
  • general aging  
  • Alzheimer’s and other diseases of the central nervous system 
  • type 2 diabetes  
  • macular degeneration, cataracts, and other vision problems 
  • Parkinson’s 
  • rheumatoid arthritis 
  • atherosclerosis

Antioxidant-Rich Fruits 

Though many sources of antioxidants come in dietary supplement form, recent research has indicated that antioxidants are more effective when in the form of actual whole fruits and veggies. In fact, some antioxidant supplements can even have the reverse effect—contributing to the creation of free radicals rather than inhibiting them. The truly best way to incorporate sufficient antioxidant content is through actual dietary sources. 

Even though any compound that counters the production of free radicals from oxidation can be considered an antioxidant, the term is typically reserved for a select number of substances that are naturally found in foods. The antioxidants most familiar to us are classic food label names like vitamin C, vitamin E, and beta-carotene. In truth, though, there are many different types of antioxidants found in food; below are some common examples of antioxidants and the fruits that contain them: 

  • anthocyanins: natural pigments found in blueberries, raspberries, and grapes  
  • carotenoids: natural pigments like beta-carotene found in pumpkins, sweet potatoes, and several types of squash  
  • catechins: polyphenols found in peaches, prunes, and apples (additionally dark chocolate)  
  • flavonoids: examples of phytochemicals found in most plants; examples include berries, tomatoes, grapes, and red wine 
  • lutein and zeaxanthin: two similar compounds found in kiwifruit, zucchini, and various leafy vegetables   
  • lycopene: a type of carotenoid found in tomatoes, watermelon, grapefruit, and papaya  
  • manganese: a diverse mineral with many uses found in blueberries, pineapple, pomegranate, and apples
  • vitamin A: a compound useful in immune system function and maintaining good vision; examples include pumpkin, cantaloupe, apricot, papaya, and mango 
  • vitamin C: also known as ascorbic acid, vitamin C is found in many citrus fruits as well as passion fruit, kiwifruit, cranberries, and strawberries
  • vitamin E: vitamin E is crucial in preventing cell membranes from free radicals, and it is found in many vegetable oils and avocados  

Health Benefits of Antioxidants      

As noted above, the presence of free radicals can have many negative effects on the body and our overall health. The potential damage to our health and body systems can come in the form of cigarette smoke, ultraviolet rays, air pollution, and countless other forces we encounter every day. Research shows that we benefit from having high antioxidant activity in order to counteract oxidative stress, but there are also some limits on what antioxidants can actually do for us. Some food labels, for instance, make bold claims about antioxidant supplements slowing the aging process or curing cancer, but the evidence doesn’t really support such claims.

In reality, having antioxidants as part of a regular, balanced diet is the best way to realize their health benefits. Indeed, part of the reason for a focus on antioxidant content in recent decades is that the lack of them was linked to developing many of the chronic diseases listed earlier. Having a diet that includes antioxidant-rich fruits and vegetables is an important part of a healthy lifestyle. Though some of these foods may even be now considered “superfoods,” they are just one part of an overall healthy way to live.
