Antioxidants help stave off a host of health problems – but figuring out how much you’re getting can be tricky
Antioxidants counteract harmful oxidants, preventing oxidative stress linked to diseases such as cancer and Alzheimer’s. Whole foods, rich in antioxidants like carotenoids and flavonoids, are more beneficial than supplements. A diverse diet featuring colorful fruits and vegetables—such as blueberries, artichokes, and dark greens—can help maintain health by providing necessary antioxidants.

When it comes to describing what an antioxidant is, it’s all in the name: Antioxidants counter oxidants.
And that’s a good thing. Oxidants can damage the structure and function of the chemicals in your body critical to life – like the proteins and lipids within your cells, and your DNA, which stores genetic information. A special class of oxidants, free radicals, are even more reactive and dangerous.
As an assistant professor of nutrition, I’ve studied the long-standing research showing how the imbalances in antioxidants and oxidants lead to oxidative stress, which is linked to cancer, diabetes, cardiovascular disease and dementia and Alzheimer’s disease. In fact, a primary cause of aging is the damage accumulated across of a lifetime of oxidative stress.
Simply put: To help prevent oxidative stress, people need to eat foods with antioxidants and limit their exposure to oxidants, particularly free radicals.
The research: Food, not supplements
There’s no way for any of us to avoid some oxidative stress. Just metabolism – the processes in your body that keep you alive, such as breathing, digestion and maintaining body temperature – are a source of oxidants and free radicals. Inflammation, pollution and radiation are other sources.
As a result, everyone needs antioxidants. There are many different types: enzymes, minerals, vitamins and phytochemicals.
Two types of phytochemicals deserve special mention: carotenoids and flavonoids. Carotenoids are pigments, with the colors yellow, orange and red; they contain the antioxidants beta-carotene, lycopene and lutein. Some flavonoids, called anthocyanins, are pigments that give foods a blue, red or purple color.
Although your body produces some of these antioxidants, you can get them from the foods you eat, and they’re better for you than supplements.
In fact, researchers found that antioxidant supplements did not reduce deaths, and some supplements in excessive amounts contribute to oxidative stress, and may even increase the risk of dying.
It should be pointed out that in most of these studies, only one or two antioxidants were given, and often in amounts far greater than the recommended daily value. One study, for example, gave participants only vitamin A, and at an amount more than 60 times an adult’s recommended intake. https://www.youtube.com/embed/uqQLpXQqMGo?wmode=transparent&start=0 A synopsis of the study that measured the antioxidant content of more than 3,000 foods.
Foods rich in antioxidants
In contrast, increased antioxidant intake from whole foods is related to decreased risk of death. And although antioxidant supplementation didn’t reduce cancer rates in smokers, the antioxidants in whole foods did.
But measuring antioxidants in foods is complicated. Extensive laboratory testing is required, and too many foods exist to test them all anyway. Even individual food items that are the same exact variety of food – such as two Gala apples – can have different amounts of antioxidants. Where the food was grown and harvested, how it was processed and how it was stored during transportation and while in the supermarket are factors. The variety of the food also matters – the many different types of apples, for instance, can have different amounts of antioxidants.
Nonetheless, in 2018, researchers quantified the antioxidant content of more than 3,100 foods – the first antioxidant database. Each food’s antioxidant capacity was determined by the amount of oxidants neutralized by a given amount of food. The researchers measured this capacity in millimoles per 100 grams, or about 4 ounces.
For fruits easily found in the grocery store, the database shows blueberries have the most antioxidants – just over 9 millimoles per 4 ounces. The same serving of pomegranates and blackberries each have about 6.5 millimoles.
For common vegetables, cooked artichoke has 4.54 millimoles per 4 ounces; red kale, 4.09 millimoles; cooked red cabbage, 2.15; and orange bell pepper, 1.94.
Coffee has 2.5 millimoles per 4 ounces; green tea has 1.5; whole walnuts, just over 13; whole pecans, about 9.7; and sunflower seeds, just over 5. Herbs and spices have a lot: clove has 465 millimoles per 4 ounces; rosemary has 67; and thyme, about 64. But keep in mind that those enormous numbers are based on a quarter-pound. Still, just a normal sprinkle packs a powerful nutritional punch.
Other tips
Other ways to choose antioxidant-rich foods: Read the nutrition facts label and look for antioxidant vitamins and minerals – vitamins A, C, E, D, B2, B3 and B9, and the minerals selenium, zinc and manganese.
Just know the label has a drawback. Food producers and manufacturers are not required to list every nutrient of the food on the label. In fact, the only vitamins and minerals required by law are sodium, potassium, calcium, iron and vitamin D.
Also, focus on eating the rainbow. Colorful foods are often higher in antioxidants, like blue corn. Many darker foods are rich in antioxidants, too, like dark chocolate, black barley and dark leafy vegetables, such as kale and Swiss chard.
Although heat can degrade oxidants, that mostly occurs during the storage and transportation of the food. In some cases, cooking may increase the food’s antioxidant capacity, as with leafy green vegetables.
Keep in mind that while blueberries, red kale and pecans are great, their antioxidant profile will be different than that of other fruits, vegetables and nuts. That’s why diversity is the key: To increase the power of antioxidants, choose a variety of fresh, flavorful, colorful and, ideally, local foods.

4 Daily Brain Health Habits for Better Cognition
Daily Brain Health Habits: Your brain works hard for you, so it’s only fair to return the favor by practicing simple everyday habits to keep this important organ strong and thriving. Start by tweaking your daily routine to focus on these four habits and eating nourishing recipes like California Grape and Sardine Avocado Toast.
4 Daily Brain Health Habits for Better Cognition
(Feature Impact) Your brain works hard for you, so it’s only fair to return the favor by practicing simple everyday habits to keep this important organ strong and thriving.
Start by tweaking your daily routine to focus on these four habits.
Prioritize Sleep
Getting quality sleep is vital for proper brain function. If you find you’ve slipped into the habit of staying up later than you should or notice your sleep being disrupted during the night, those are signs to revisit your sleep hygiene practices. Start by establishing a regular bedtime and wake-up time that will give you the recommended 7-9 hours of sleep. Turn your bedroom into a comfortable refuge from the world – keep it cool and dark, and set up fans or noise machines if you need them to quiet your mind. Avoid consuming caffeine or alcohol too close to bedtime and try switching to a book instead of a screen when it’s time to wind down.
Eat Smart
Just like the rest of the body, the brain is nourished by food. Some of its favorite foods are options rich in healthy fats like fish, avocado, olive oil and nuts, as well as vegetables like leafy greens, which offer carotenoids, and fruits such as grapes, which deliver antioxidants and other polyphenols.
Combine several of these powerful brain-boosting foods at once with this California Grape and Sardine Avocado Toast recipe. The fish is rich in omega-3 fatty acids and the avocado offers a boost of healthy unsaturated fat, while the grapes add protective dietary flavonols, which may help promote anti-inflammatory and beneficial antioxidant activity.
A study published in the scientific journal “Neurology” found a higher intake of certain flavonols – including three naturally found in grapes – is associated with a 48% decreased risk of developing Alzheimer dementia.
Get Moving
Adding even more proof that what’s good for your body is good for your mind, getting regular exercise is one of the best things you can do for your brain. Motivate yourself by choosing a form of movement you genuinely enjoy, whether it’s a daily walk on a nearby nature trail, a dance class, a bike ride or a heart-pumping workout video.
Challenge Your Mind
Don’t forget to give your brain its own workout, too. Doing something mentally stimulating every day is a great way to keep yourself sharp, and there are plenty of ideas to choose from. Try learning a new language, picking up a musical instrument, playing a mind-engaging card or board game, doing a puzzle, reading a book or immersing yourself in a creative writing or art project. The options are nearly endless, and if you want to make your brain extra happy, you can snack on handfuls of grapes as you enjoy your hobby.
