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. (13, 14)
To date, studies have confirmed that chronic inflammation contribute to factors that increase your risk of developing cancer, including DNA mutations and cancer cell growth. Research has confirmed that the antioxidants in dark chocolate have a strong ability to fight the DNA damage that could lead to cancer development, as well as reduce certain inflammation enzymes that could encourage its growth (12).
So, if you have been working out for a couple of weeks or are preparing yourself for a marathon soon, you would probably need something that will increase your endurance and help you workout or practice for a longer period. In that case, what could be better than chocolate milk? This will take good care of your body, boost strength and energy and help you give a hundred percent!

Herbert's blood sugar was measured on seven different days before and during the challenge. Her average before was 6.0 and while consuming zero sugar it was 5.4. Catsicas says, "It seems cutting sugar out of the diet significantly improves average blood glucose levels. Maintaining lower blood glucose levels is beneficial as it places less stress on the beta cells in the pancreas to produce insulin.
Cacao contains more than 300 compounds, including protein, fat, carbohydrates, fiber, iron, zinc, copper, calcium and magnesium, according to a Natural News article. “Magnesium helps to build strong bones and is a muscle relaxant associated with feelings of calmness,” the report adds. “Cacao is also high in sulfur, which helps form strong nails and hair.”
Certain vitamins and minerals support healthy blood sugar levels. Magnesium in leafy green vegetables and nuts, for instance, can improve insulin sensitivity. Eating a whole, unprocessed foods diet can provide these nutrients to optimize immune function. A multivitamin-mineral (available for men, women, and kids) can cover the nutrient bases you might not be getting from food.
The body can cope with some free radicals and needs them to function effectively. However, the damage caused by an overload of free radicals over time may become irreversible and lead to certain diseases, including heart disease, liver disease and some cancers (such as oral, oesophageal, stomach and bowel cancers). Oxidation can be accelerated by stress, cigarette smoking, alcohol, sunlight, pollution and other factors.
Some nutrients are destroyed in the process of making chocolate available for the general market. Make sure the chocolate you buy is within the healthy range. Check the label: Chocolate with a 60 percent or higher cocoa content is packed full of nutrients and antioxidants. Often called bittersweet, it has minimal sugar. The best way to get all the nutrients from chocolate is simply to use unsweetened cocoa nibs. The bitter, crunchy, seed-like snack isn't the best-tasting treat, but its nutritional profile makes it worthwhile.
"I'm a terrible sleeper and I can function on little sleep," says Herbert. Before the challenge she slept an average of seven hours per night and during the experiment her average dropped to 6.1 hours. "I don't think the challenge itself made a difference to my sleeping pattern, but it did take more time to prepare healthy, sugarless food. That's probably why I slept less during the challenge." 
Juicy and tart Montmorency cherries are your best source of the antioxidant melatonin. Other cherries have it, too, but Montmorency has the most. Melatonin protects the skin against ultraviolet radiation. Researchers have discovered that this powerful little nutrient also helps repair sunburned skin, since 
it stimulates new skin-cell growth. Cherries are also packed with vitamin C, which is needed to build collagen—your skin’s natural “scaffolding” and a wrinkle preventer. Here are some more foods proven to fight wrinkles (and two you should avoid).
The category includes 52 products, including European, Scandinavian and American products. The variation in antioxidant content in dinner and dessert products for infants varies from 0.02 to 1.25 mmol/100 g. Interestingly, human breast milk (49 samples from Norwegian mothers) has a mean content of 2.0 mmol/100 g. In addition, the category includes two Norwegian dog rose products for infants with antioxidant contents of 6.7 and 18.5 mmol/100 g.

"The bottom line is the same: eat more fruits and veggies," says Ronald L. Prior, Ph.D., a chemist and nutritionist with the USDA's Arkansas Children's Nutrition Center in Little Rock, Ark., and lead author of the study. "This study confirms that those foods are full of benefits, particularly those with higher levels of antioxidants. Nuts and spices are also good sources."
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.
Initial studies have been carried out to examine the association between intake of antioxidant rich foods and their health effects [67,70]. Some of these studies describe a beneficial effect on oxidative stress related chronic diseases, e.g. from intake of nuts [49,69], pomegranates [71-73], tomatoes [6], coffee [74], tea [54,75,76], red wine [77-79] and cocoa [56]. The highly reactive and bioactive phytochemical antioxidants are postulated to in part explain the protective effect of plant foods. An optimal mixture of different antioxidants with complementary mechanisms of action and different redox potentials is postulated to work in synergistic interactions. Still, it is not likely that all antioxidant-rich foods are good sources and that all antioxidants provided in the diet are bioactive. Bioavailability differs greatly from one phytochemical to another [26,27,80], so the most antioxidant rich foods in our diet are not necessarily those leading to the highest concentrations of active metabolites in target tissues. The antioxidants obtained from foods include many different molecular compounds and families with different chemical and biological properties that may affect absorption, transport and excretion, cellular uptake and metabolism, and eventually their effects on oxidative stress in various cellular compartments [24]. Biochemically active phytochemicals found in plant-based foods also have many powerful biological properties which are not necessarily correlated with their antioxidant capacity, including acting as inducers of antioxidant defense mechanisms in vivo or as gene expression modulators. Thus a food low in antioxidant content may have beneficial health effects due to other food components or phytochemicals executing bioactivity through other mechanisms.
Unlike sugar, salt also appears beneficial to our brain. Indeed, sodium helps to move vitamin C into the brain, whereas glucose competes with its uptake. Sugar also depletes the body of B vitamins, including thiamine, which is extremely important for brain health. This suggests that consuming salt is indeed good, and even necessary, for brain health whereas overconsuming sugar wreaks havoc.
So how do antioxidants improve our health? Consider that your cells are constantly producing a variety of harmful chemicals called free radicals. In addition, your body is also exposed to free radicals in the environment—cigarette smoke, air pollution, and sunlight, for example. These free radicals trigger a process called “oxidative stress,” which damages cells. Oxidative stress is implicated in the aging process and also in many chronic diseases, from cancer to cardiovascular diseases, and from diabetes to dementia.
Currently, there are no government guidelines for consumers on how many antioxidants to consume and what kind of antioxidants to consume in their daily diet, as is the case with vitamins and minerals. A major barrier to such guidelines is a lack of consensus among nutrition researchers on uniform antioxidant measurements. Scientists will soon attempt to develop such a consensus at the First International Congress on Antioxidant Methods, held June 16-18 at the Caribe Royale Hotel and Conference Center in Orlando, Fla., with the ultimate goal of developing better nutritional data for consumers. ACS is the principal sponsor of the meeting.
But before you run out and stock up on chocolate bars, it’s important to note that you’d have to eat about seven bars a day to ingest the 138 milligrams of epicatechin given to the study participants. A healthy portion of dark chocolate is about 1.5 ounces. However, the results do suggest an important link between the compound and memory-loss. Certain supplements contain healthy doses of epicatechin, and the antioxidant can also be found naturally in apples, blackberries, and green tea. 
An excerpt of the 425 spices and herbs analyzed in our study are presented in Table ​Table5.5. The study includes spices and herbs from 59 different manufacturers or countries. Twenty seven single products are in the range 100 to 465 mmol/100 g, but the variation is from 0.08 mmol/100 g in raw garlic paste procured in Japan, to 465 mmol/100 g in dried and ground clove purchased in Norway. Sorted by antioxidant content, clove has the highest mean antioxidant value, followed by peppermint, allspice, cinnamon, oregano, thyme, sage, rosemary, saffron and estragon, all dried and ground, with mean values ranging from 44 to 277 mmol/100 g. When analyzed in fresh samples compared to dried, oregano, rosemary and thyme have lower values, in the range of 2.2 to 5.6 mmol/100 g. This is also true for basil, chives, dill and parsley. In addition to common spices and culinary herbs, we have also analyzed other herbs, like birch leaves, wild marjoram and wood cranesbill among others. Details on all herbs can be found in Additional file 1, the Antioxidant Food Table.
Efforts to mimic nature’s antioxidants have largely failed. In fact, some antioxidant supplements, such as vitamin E and beta-carotene, are even harmful to health in large doses. The National Center for Complementary and Integrative Health (NCCIH) recommends, “Do not use antioxidant supplements to replace a healthy diet or conventional medical care, or as a reason to postpone seeing a healthcare provider about a medical problem. If you are considering a dietary supplement, first get information on it from reliable sources.” Dietary supplements contain active ingredients, so always check for interactions with your medications.
A recent study published in Hypertension showed that performance on cognitive tests significantly improved in elderly individuals with mild cognitive impairment if they consumed a daily cocoa drink containing high levels of flavanols for eight weeks, compared to those who consumed a low-flavanol cocoa drink. (Flavonols are a member of the polyphenol family—compounds found in natural plant food sources that have antioxidant properties.) Because dark chocolate contains more cocoa solids than other types of chocolate, it naturally contains more flavanols.
There is not necessarily a direct relationship between the antioxidant content of a food sample consumed and the subsequent antioxidant activity in the target cell. Factors influencing the bioavailability of phytochemical antioxidants, include the food matrix, absorption and metabolism [24-27]. Also, the methods measuring total antioxidant capacity do not identify single antioxidant compounds, and they are therefore of limited use when investigating the mechanisms involved. This is however, not the scope of this article. With the present study, food samples with high antioxidant content are identified, but further investigation into each individual food and phytochemical antioxidant compound is needed to identify those which may have biological relevance and the mechanisms involved.
The first high antioxidant foods that probably come to mind is probably fruits and vegetables, and for good reason! They rich in antioxidants and other healthy food components, such as slow release carbohydrates, protein and fiber. Here are the top 15 antioxidant fruits and vegetables commonly available in the U.S. Figures reflect antioxidant content in millimoles (mmol) per 100 g.
Glutathione is considered the body’s most important antioxidant because it’s found within the cells and helps boost activities of other antioxidants or vitamins. Glutathione is a peptide consisting of three key amino acids that plays several vital roles in the body, including helping with protein use, creation of enzymes, detoxification, digestion of fats and destruction of cancer cells.
If you have diabetes, too much sugar can lead to kidney damage. The kidneys play an important role in filtering your blood sugar. Once blood sugar levels reach a certain amount, the kidneys start to let excess sugar into your urine. If left uncontrolled, diabetes can damage the kidneys, which prevents them from doing their job in filtering out waste in your blood. This can lead to kidney failure.
Really good point above, Tanya. As a physician I recommend that many patients use supplements (carefully selected–I like ConsumerLab.com and Labdoor.com–they test for purity and contaminants of numerous brands out there), but I also warn lots of patients, especially as those taking blood thinners (e.g., Coumadin or possibly Xarelto) NOT to use hemp/CBD/Medical THC or turmeric because those natural products could interact with their blood thinners (and even some anti platelet medications like Plavix & Aspirin) to cause a dangerous hemorrhage. Also, not to take things in excess, even if ‘natural,’ because our liver and kidneys still have to metabolise them–so have your doctor monitor the function of both organ systems at least yearly. Always good to be informed when adding integrative medicine to our daily regimens.

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.
Sugar and refined carbohydrates are considered 'empty calories', mainly because they don't contain any useful nutrients. Some foods high in sugar are heavily processed, and the sweet stuff is added to make them more palatable and desirable. It's these foods that are not always easy to spot the sugar in, and often those that are marketed as 'healthy', or low in fat which can be the worst offenders. In some cases, ready meals could contain up to 12 teaspoons of sugar per portion, a can of cola houses six and a bowl of dry Bran Flakes has three.
Oxidative stress is believed to play a central role in the pathogenesis of neurodegenerative diseases, but a nutrient-dense diet seems to lower one’s risk. The Journal of the American Medical Association of Neurology reports that higher intake of foods rich in antioxidants, such as vitamin C and vitamin E, may modestly reduce long-term risk of dementia and Alzheimer’s. (10)

The variation in antioxidant content in dinner and dessert products for infants varies from 0.02 to 1.25 mmol/100 g. Interestingly, human breast milk (49 samples from Norwegian mothers) has a mean content of 2.0 mmol/100 g.

A study published in International Journal of Cardiology had subjects either consume a daily dose of flavonoid-rich dark chocolate or non-flavonoid white chocolate for two weeks. The results showed that flavonoid-rich dark chocolate intake significantly improved heart circulation in healthy adults. On the other hand, white chocolate with zero flavonoids to brag about had no positive health effects on the subjects. (6)
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.”
“Given chocolate’s rich supply of flavonoids, researchers have also investigated whether it may play a role in cancer prevention. The studies in cancer prevention are still emerging. A recent review of studies on the cancer protective properties of cocoa concluded that the evidence is limited but suggestive. More rigorous studies should be conducted on chocolates’ cancer protective role, concluded the author, because it provides ‘strong antioxidant effects in combination with a pleasurable eating experience.'”

Protects against sun –The flavonols can protect against sun-induced damage, improve blood flow to the skin and increase skin density and hydration. If you are out in the sun, dark chocolate can reduce your possibilities of getting sun burned or just help not to burn your skin as much. And if you were to get sun burned, it can help you heal quicker.
No, it’s not your imagination; some research supports the idea that chocolate really can boost your mood. It’s the fatty acids that do the trick, and dark chocolate contains two saturated fatty acids — palmitic and stearic acids — in addition to its health-boosting flavonoids. More research needs to be done, DuBost says, but studies have found that chocolate in particular can make you feel happier and improve your mood. The theory is that chocolate stimulates the neural activity in the regions of the brain associated with pleasure and reward, she says.
A recent study by Swedish researchers found that women who ate high amounts of chocolate — about two candy bars per week — had a 20 percent lower risk of stroke. In a similar study, British researchers also found that people who ate more chocolate were 30 percent less likely to have a stroke. However, researchers added that more study is needed to determine the exact amount and types of flavonoid-rich chocolates that would be most help lessen stroke risk.
