The protective effect of antioxidants continues to be studied around the world. For instance, men who eat plenty of the antioxidant lycopene (found in tomatoes) may be less likely than other men to develop prostate cancer. Lutein, found in spinach and corn, has been linked to a lower incidence of eye lens degeneration and associated blindness in the elderly. Flavonoids, such as the tea catechins found in green tea, are believed to contribute to the low rates of heart disease in Japan.
Although it’s not conclusively proven to be addictive, sugar does seem to have that effect on the brain. “Energy-dense, sweet-tasting foods may lead to reinforcement of consuming those foods in a part of the brain called the limbic system,” Dr. Saltzman says. “In essence, we are training our brains to like and to want these sweet-tasting foods, and this may lead to increased consumption.” Dr. Malik also says sugar may stimulate the pleasure centers of your brain, similar to the way drugs do. Try these surprising ways to kick your sugar addiction.
It’s not exactly agreed upon who first “discovered” antioxidants. Antioxidants have been dated in medical literature to the early 19th and 20th centuries, but researchers and health experts have been discussing them for much longer. Each antioxidant has its own unique history of discovery. Some, such as vitamin C and vitamin E, were first researched by doctors, such as Henry A. Mattill during the 1920s–1950s, used to explain why animals fed whole foods lived longer and remained healthier. (2)
Editor's Note: USDA scientists analyzed antioxidant levels in more than 100 different foods, including fruits and vegetables. Each food was measured for antioxidant concentration as well as antioxidant capacity per serving size. Cranberries, blueberries, and blackberries ranked highest among the fruits studied. Beans, artichokes, and Russet potatoes were tops among the vegetables. Pecans, walnuts, and hazelnuts ranked highest in the nut category.

In the category "Beverages", 283 products were included, from coffee and tea to beer, wine and lemonades. Dry products like coffee beans and dried tea leaves and powders were also included. The highest antioxidant values in this category were found among the unprocessed tea leaves, tea powders and coffee beans. In Table ​Table22 we present an excerpt of this category and of the analyses of fruit juices. Fifty-four different types of prepared coffee variants procured from 16 different manufacturers showed that the variation in coffees are large, ranging from a minimum of 0.89 mmol/100 g for one type of brewed coffee with milk to 16.33 mmol/100 g for one type of double espresso coffee, the highest antioxidant value of all prepared beverages analyzed in the present study. Other antioxidant rich beverages are red wine, which have a smaller variation of antioxidant content (1.78 to 3.66 mmol/100 g), pomegranate juice, prepared green tea (0.57 to 2.62 mmol/100 g), grape juice, prune juice and black tea (0.75 to 1.21 mmol/100 g) (Table ​(Table2).2). Beer, soft drinks and ginger ale contain the least antioxidants of the beverages in our study, with drinking water completely devoid of antioxidants.
An unhealthy liver is just one of the many effects of sugar on the body, especially when it’s consumed in large amounts.  “Fructose is metabolized in the liver, and consuming too much can lead to the production of fat in the liver, which is another path to adverse metabolic health,” Dr. Malik says. According to the University of California San Francisco, rates of non-alcoholic fatty liver disease, as well as scarring of the liver, have doubled since 1980. Follow these 9 tricks to reverse a sugar binge.
You may want to skip the dessert on date night: Sugar may impact the chain of events needed for an erection. “One common side effect of chronically high levels of sugar in the bloodstream is that it can make men impotent,” explains Brunilda Nazario, MD, WebMD’s associate medical editor. This is because it affects your circulatory system, which controls the blood flow throughout your body and needs to be working properly to get and keep an erection.

The "glycemic index" is a measure of how a given food affects blood-glucose levels, with each food being assigned a numbered rating. The lower the rating, the slower the absorption and digestion process, which provides a more gradual, healthier infusion of sugars into the bloodstream. On the other hand, a high rating means that blood-glucose levels are increased quickly, which stimulates the pancreas to secrete insulin to drop blood-sugar levels. These rapid fluctuations of blood-sugar levels are not healthy because of the stress they place on the body.
You’ve heard about the benefits of antioxidants, and thanks to our antioxidant guide, you’ve learned about what they are and what they do for your body and mind. But which fruits and vegetables are the best sources? Here are the 10 fruits and vegetables that are the top sources of antioxidants. All of them are healthy. All of them are delicious. Best of all, they all make great additions to smoothies!
In the nuts and seeds category we analyzed 90 different products, with antioxidant contents varying from 0.03 mmol/100 g in poppy seeds to 33.3 mmol/100 g in walnuts, with pellicle and purchased with nut shell intact. Pecans with pellicle, sunflower seeds and chestnuts with pellicle, have mean antioxidant content in the range of 4.7 to 8.5 mmol/100 g (Table ​(Table3).3). Walnuts, chestnuts, peanuts, hazelnuts and almonds have higher values when analyzed with the pellicle intact compared to without pellicle.
Just like any other supplement, it doesn’t seem that it’s beneficial or even necessarily safe to consume high doses of antioxidants in supplement form. For example, because during exercise oxygen consumption can increase by a factor of more than 10, taking high doses of antioxidants might interfere with proper exercise recovery. (12) Other research has shown that high-dose antioxidant supplementation may interfere with the cardiovascular benefits of exercise, have negative effects on the body’s natural anti-cancer activities, and affect how the body balances levels of different chemicals and nutrients on its own.

Of all the cruciferous vegetables, broccoli stands out as the most concentrated source of vitamin C, plus it possesss the flavonoids necessary for vitamin C to recycle effectively. Also concentrated in broccoli are the carotenoids lutein, zeaxanthin and beta-carotene. But, the antioxidant which is the real standout in broccoli is indole-3-carbinol, a powerful antioxidant compound and anti-carcinogen found to not only hinder the growth of breast, cervical and prostate cancer, but also has been shown to boost liver function.
It’s helpful to understand a little about how sugar is used by the brain. The carbohydrates you eat, including sugars, are broken down into glucose. Your brain needs glucose to function properly. Unfortunately, many people eat much more sugar than they need. According to the Department of Health and Human Services, the average American eats the equivalent of about 42 teaspoons of sugar a day. That added sugar comes from various sources, such as table sugar, baked goods, and sugary drinks.
