Before you swap refined sugar for artificial sweeteners, you may want to keep reading. Artificial sweeteners also appear to have several negative effects on the brain. Sweeteners, such as aspartame, sucralose, and saccharin, are not healthy alternatives to sugar. These sweeteners are in a variety of foods and drinks, such as diet soda, sugar-free snacks, and energy drinks.
Among dark chocolate’s most researched benefit is its role in preventing heart disease. British researchers analyzed seven studies on chocolate and cardiovascular health involving more than 114,000 people in the United States, Germany, Japan, the Netherlands, and Sweden and found that people who ate more chocolate significantly reduced their risk for heart disease. Researchers concluded that people who ate the most chocolate weekly had a 37 percent lower risk of any heart disease than those who ate the least amounts of dark chocolate.
Dark chocolate makes my list of 15 brain foods to boost focus and memory for good reason. Previous research showed that “acute as well as chronic ingestion of flavanol-rich cocoa is associated with increased blood flow to cerebral gray matter and it has been suggested that cocoa flavanols might be beneficial in conditions with reduced cerebral blood flow, including dementia and stroke.”
Various types of chocolate were analyzed, from milk chocolate to dark chocolate and baking cocoa. The variation of antioxidant content in chocolate ranged from 0.23 in white chocolate to 14.98 mmol/100 g in one individual dark chocolate sample. Mean antioxidant contents increased with increasing content of cocoa in the chocolate product (Pearson correlation r = 0.927, p < 0.001). Chocolate products with cocoa contents of 24-30%, 40-65% and 70-99% had mean antioxidant contents of 1.8, 7.2 and 10.9 mmol/100 g, respectively.

Are you familiar with Dragon’s Blood? (Hint: it is NOT the secret ingredient in Gandalf’s potions.) Also known as Sangre de Grado, this sap from a tree grown in Peru happens to contain the highest antioxidant content of 3,100 foods and beverages measured worldwide. Now before you run to the nearest health food store looking for this special elixir, keep in mind that there are plenty of food items with high antioxidant values.

Evidence that dark chocolate may play a role in cancer prevention is limited but growing. Some preliminary studies on three continents — Europe, Asia, and North America — have shown that people who eat many flavonoids or a lot of antioxidant-rich chocolate develop fewer cancers than those who don’t consume them. Of the many flavonoids in chocolate, two in particular, epicatechin and quercetin, are believed to be responsible for the cancer-fighting properties.

Spinach is one of the richest sources of antioxidants, with one cup containing over 3,600 IU of beta-carotene, which is an antioxidant known for its anti-cancer, anti-aging properties, and heart protecting properties. Spinach also offers an abundance of the antioxidant, lutein, which is beneficial in protecting your eyes from macular degeneration and cataracts.
When it comes to protection against things like cancer or heart disease, overall the medical literature seems conflicting. Although some studies found a positive relationship between antioxidant supplementation and risk reduction, others have not found such positive effects. (15) To be safe, always follow directions carefully and speak with your doctor if you’re unsure of whether or not a supplement is right for you. And to remain your healthiest into older age, aim to reduce free radical load in your body by practicing things like:
Sources of antioxidants in your diet offer much-needed help in counteracting the damage done by things like blue light or sun exposure, a poor diet, smoking or using other drugs, taking medications, toxicity or chemical exposure, even high amounts of stress and other natural factors that increase the risk of age-related problems. In the process of fighting free radical damage, antioxidants protect healthy cells while halting the growth of malignant or cancerous cells.
With this study we present a comprehensive survey of the total antioxidant capacity in foods. Earlier small-scale studies from other laboratories have included from a few up to a few hundred samples [20-22,29-31], and in 2007 the U.S. Department of Agriculture presented the Oxygen Radical Absorbance Capacity (ORAC) of Selected Foods report including 277 food samples [23]. These studies have been done using different antioxidant assays for measuring antioxidant capacity making it difficult to compare whole lists of foods, products and product categories. Still, a food that has a high total antioxidant capacity using one antioxidant assay will most likely also be high using another assay [20-22]. Consequently, the exact value will be different but the ranking of the products will be mainly the same whichever assay is used. In the present extensive study, the same validated method has been used on all samples, resulting in comparable measures, thus enabling us to present a complete picture of the relative antioxidant potential of the samples.
Cranberries are not just another staple on the American Holiday table. They pack some serious antioxidant punch and are also well known for their beneficial effect on preventing urinary tract infections. Try 100% cranberry juice diluted in water or sparkling water for a refreshing, tart drink, or add some unsweetened dried cranberries to your trail mix.
Your diet should include five daily serves of fruit and vegetables. One serve is a medium-sized piece of fruit or a half-cup of cooked vegetables. It is also thought that antioxidants and other protective constituents from vegetables, legumes and fruit need to be consumed regularly from early life to be effective. See your doctor or dietitian for advice.

Many foods have way more sugar than you realize. The USDA’s Dietary Guidelines say no more than 10 percent of your calories should come from added sugar—for a 2,000 calorie diet that’s 200. The American Heart Association is stricter, with a limit of 100 calories for women and 150 for men. “The term ‘added sugars’ indicates sugars that are added to processed and prepared foods, as well as sugars added at the time of consumption,” says Dr. Saltzman. “Most research focuses on these added sugars as potentially harmful.” For example, if you have a Milky Way, which contains 31 grams (124 calories) of added sugar, you’re practically at your limit already. Bottom line? Read nutrition labels to see how much you’re getting. Next, read up on the 40 sneaky names for sugar you may not recognize.
On January 2, a snail named George shriveled up and died in his tank at the University of Hawaii. He was 14 years old, which for a land snail is pretty long in the tooth (or in George's case, radula). But in all of his years, George never sired any offspring. There were simply no mating partners to be found. In fact, George was the last known member of his species, Achatinella apexfulva. And the moment he slimed off this mortal coil, 2019 experienced its first documented extinction.
Eating sugar gives your brain a huge surge of a feel-good chemical called dopamine, which explains why you’re more likely to crave a candy bar at 3 p.m. than an apple or a carrot. Because whole foods like fruits and veggies don’t cause the brain to release as much dopamine, your brain starts to need more and more sugar to get that same feeling of pleasure. This causes those “gotta-have-it” feelings for your after-dinner ice cream that are so hard to tame.
But how much salt should you eat each day? While every guideline and health authority would have you eating no more than one teaspoonful of salt per day, evidence from studies published in the medical literature suggests that most people should eat around 1½ to 2 teaspoons of salt per day. More salt may be needed if you are an avid exerciser and lose salt in sweat or out the urine via coffee intake.
One of the immediate effects of sugar on the body is the release of more insulin, which regulates blood sugar. Soda is the worst culprit, says Vasanti Malik, ScD, a research scientist at the Harvard T.H. Chan School of Public Health. “Sugars in beverages are absorbed very quickly, which results in rapid increases in blood glucose and insulin,” she says. “Over time this can lead to insulin resistance [in which the body needs more and more insulin to be effective], and place an individual on a pathway to adverse metabolic health.” Naturally occurring sugars, as in fruit, don’t have the same negative effects because they’re paired with fiber, which helps slow absorption.
Prior says that the data should prove useful for consumers seeking to include more antioxidants in their diet. But he cautions that total antioxidant capacity of the foods does not necessarily reflect their potential health benefit, which depends on how they are absorbed and utilized in the body. Researchers are still trying to better understand this process, he adds.
It’s important to maintain the balance between antioxidants and oxidants in the body for good health. However, the free radicals or oxidants usually outnumber the antioxidants naturally produced in the body. Therefore, it is important to have a continuous supply of antioxidants from an external source to maintain this balance. Your diet is this external source and it must be packed with good quality antioxidants. This, in turn, provides other benefits like slowing down the signs of ageing, making your skin look youthful and lowering the risk of heart disease. A diet rich in antioxidants is also known to keep your brain active and your gut healthy. Needless to say, all these factors help in improving the quality and length of your life.Here are seven antioxidant rich foods that you must eat regularly and add to your daily diet if you haven’t already:

Vitamin A and C have been connected to a decrease in the appearance of wrinkles and skin dryness. Vitamin C, specifically, is a powerful antioxidant that can help reduce the effect of oxidative damage caused by pollution, stress or poor diet. Vitamin A deficiency has also been linked to skin dryness, scaling and follicular thickening of the skin. Similarly to how free radicals damage surface skin cells, keratinization of the skin, when the epithelial cells lose their moisture and become hard and dry, can occur in the mucous membranes of the respiratory, gastrointestinal tract and urinary tract.
