That’s why one bite of ice cream never feels like enough and before you know it, you’re looking at the bottom of a pint. Or why you find McDonald’s french fries so hard to resist—the ingredient list includes both dextrose, an added sugar, and fat in the form of canola oil, corn oil, soybean oil and hydrogenated soybean oil. Dip those fries in ketchup and you’re getting even more sugar—this time high fructose corn syrup.
Studies show that the darker the chocolate, the better. Eat only less-processed chocolate that contains at least 65 percent cacao, recommends Joy DuBost, PhD, RD, an American Dietetic Association spokeswoman. Not only does dark chocolate have a higher concentration of antioxidants than milk chocolate, but milk chocolate is also higher in added sugar and unhealthy fats. Still, the daily dose of antioxidants in dark chocolate doesn’t give you license to indulge in a dessert free-for-all — dark chocolate is still loaded with fat and calories — so eat a max of 1 to 2 ounces a day. If you do, research says you’ll reap these 9 benefits.
Like its parent fruit, dark chocolate is also packed with potent antioxidants and contains various essential nutrients which help you to stay healthy and beautiful. Powerful antioxidants like flavonoids help to avoid cardiovascular disorders and reduce risks of strokes. In addition, it also works to keep your blood cholesterol level and blood pressure in check. Seamless vision is another health benefit offered by this magical ingredient.

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.
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.
I have always loved dark chocolate, and I actually prefer it over other types of chocolate! Because of that, it makes me really excited to hear that there are some health benefits to eating it! It’s interesting how you point out that dark chocolate has antioxidants that stimulate the lining of the arteries so that blood flow can improve. Blood flow is actually something that many people in my family struggle with. I’ll have to suggest they start eating more dark chocolate! I imagine that giving them dark chocolate would be a great gift and also a way to help them out!
Luckily, increasing your daily antioxidant intake is pretty simple; they're found in many of your favorite fruits, nuts, veggies, and even sweets! Wondering where to find the most antioxidants? We combed through a database of more than 3,100 foods, drinks, herbs, and spices (originally compiled and published in Nutrition Journal in 2010) to find the top 10 antioxidant-rich foods (per 100 grams) that you need in your diet.
Let’s not forget about our little ones! When New York City public schools reduced the amount of sugar in their lunches and breakfasts, their academic ranking increased 15.7% (previously, the greatest improvement ever seen had been 1.7%).11 The study also eliminated artificial colors, synthetic flavoring, and two preservatives, showing the importance of natural ingredients for children.
Small-scale studies have indicated for quite some time that regular intake of cocoa can have a positive effect in fighting cardiovascular disease. A more recent study on cocoa's cardiovascular benefits, done in 2006, proved this among a larger study group of 470 men, all tested while consuming different daily doses of cocoa. The conclusions were that cocoa does indeed lower the chances and significance of cardiovascular disease.
Why should I care about antioxidants? The short answers is because healthy pros say so; the longer one is because the higher antioxidant foods and products we welcome into our lives, the more able our bodies are able to stop or delay the damaging of cells. Oxidants — the opposite of anitoxidants –are free radicals naturally produced by our bodies to help fight off viruses and other health-inhibiting invaders. They also occur in our environment via air pollution, smoke, alcohol etc. which can cause an unhealthy buildup in our systems. Oxidant overload can lead to accelerated aging, weakened immunity, and cellular damage linked to disease among other major health hurdles down the line. On the logical flip-side, inviting more antioxidants into our bodies directly combats these adverse effects.

When you consume refined sugar, your sweet taste receptors signal the brain’s reward system in a way that is much more potent than consuming a piece of fruit—your brain lights up like a pinball machine due to the intense release of dopamine. Unfortunately, those sweet taste receptors don’t signal you to stop eating when you’ve had too much sugar. In fact, the more sugar you eat, the more you crave, creating a vicious cycle of sugar dependence. On the other hand, if you eat loads of the other white crystal (salt), your salt taste receptors "flip" and provide you with an aversion signal. In other words, if you consume too much salt in a meal, your body has a built-in safety mechanism causing you to crave less salt later in the day. Your body is extremely smart when it comes to regulating the intake of essential minerals, especially one as important as salt.

The American Heart Association, along with the Mayo Clinic and Cleveland Clinic, recommend getting antioxidants from whole foods and a wide variety of foods. While it’s always ideal, and usually more beneficial, to get antioxidants or other nutrients directly from real food sources, certain types may also be helpful when consumed in supplement form.
Small-scale studies have indicated for quite some time that regular intake of cocoa can have a positive effect in fighting cardiovascular disease. A more recent study on cocoa's cardiovascular benefits, done in 2006, proved this among a larger study group of 470 men, all tested while consuming different daily doses of cocoa. The conclusions were that cocoa does indeed lower the chances and significance of cardiovascular disease.
Just like many of us love to eat chocolate, so does the good bacteria living in your gut, according to a study presented to the American Chemical Society. The nutrients found in chocolate, such as polyphenols, antioxidants, and fiber, aren’t easily digestible, but when good bacteria feeds on the fiber, compounds that are smaller, easily absorbable, and non-inflammatory are released. As a result, inflammation in cardiovascular tissue can be reduced.
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.
One of my favorite benefits of dark chocolate is its free radical fighting ability. Free radicals are unbalanced compounds created by cellular processes in the body, especially those that fight against environmental toxins we’re exposed to on a daily basis. Antioxidants are the compounds that are believed to neutralize free radicals and protect the body from their damage.

Reduces stress –If you are one of those chocolate lovers, you know that feeling of happiness and guilt when you put in your mouth that piece of flavorful candy. Now imagine that same feeling but without the guilt! You can achieve that with dark chocolate because now you know that it is better for your health and has much more benefits than regular or milk chocolate. There has been studies were people that ate dark chocolate showed a decreased amount of stress hormone levels.
No introductions are needed for this highly treasured food that dates back to 2000 BC. At that time, the Maya from Central America, the first connoisseurs of chocolate, drank it as a bitter fermented beverage mixed with spices or wine. Today, the long rows of chocolate squares sitting neatly on your store shelves are the end result of many steps that begin as a cacao pod, larger than the size of your hand. Seeds (or beans) are extracted from the pod and fermented, dried, and roasted into what we recognize as cocoa beans. The shells of the bean are then separated from the meat, or cocoa nibs. The nibs are ground into a liquid called chocolate liquor, and separated from the fatty portion, or cocoa butter. The liquor is further refined to produce the cocoa solids and chocolate that we eat. After removing the nibs, the cocoa bean is ground into cocoa powder that is used in baking or beverages.
Legally, milk chocolate only needs to be at least 10 percent pure chocolate with at least 3.39 percent milk fat and at least 12 percent milk solids. (17)  Studies have shown that the proteins in milk might reduce the absorption of the healthy antioxidants from cocoa. What’s the problem with milk? Milk actually appears to bind itself to the flavonoids in chocolate, making them unavailable to our bodies. (18) This is why milk chocolate is not a good antioxidant source. It’s also why you don’t want to drink milk with your dark chocolate.
Have a big meeting, test or dinner with the in-laws? Eating dark chocolate can give your brain a short-term boost—increasing your alertness—for two to three hours, a University of Nottingham study found. Flavanols, one of dark chocolate’s key components, dilates blood vessels, allowing more oxygen and blood to reach key areas of the brain, which can help you soldier against fatigue and the effects of aging. The study participants consumed a flavanol-rich cocoa drink, but you can eat dark chocolate by itself—or any foods high in flavanols like red wine, green tea and blueberries. 
It is widely accepted that a plant-based diet with high intake of fruits, vegetables, and other nutrient-rich plant foods may reduce the risk of oxidative stress-related diseases [1-6]. Understanding the complex role of diet in such chronic diseases is challenging since a typical diet provides more than 25,000 bioactive food constituents [6], many of which may modify a multitude of processes that are related to these diseases. Because of the complexity of this relationship, it is likely that a comprehensive understanding of the role of these bioactive food components is needed to assess the role of dietary plants in human health and disease development. We suggest that both their numerous individual functions as well as their combined additive or synergistic effects are crucial to their health beneficial effects, thus a food-based research approach is likely to elucidate more health effects than those derived from each individual nutrient. Most bioactive food constituents are derived from plants; those so derived are collectively called phytochemicals. The large majority of these phytochemicals are redox active molecules and therefore defined as antioxidants. Antioxidants can eliminate free radicals and other reactive oxygen and nitrogen species, and these reactive species contribute to most chronic diseases. It is hypothesized that antioxidants originating from foods may work as antioxidants in their own right in vivo, as well as bring about beneficial health effects through other mechanisms, including acting as inducers of mechanisms related to antioxidant defense [7,8], longevity [9,10], cell maintenance and DNA repair [11].
According to Harvard University, a systolic pressure under 120 (the first number) and a diastolic pressure under 80 (the second number) is considered normal. Hypertension, or high blood pressure, is indicated by a systolic pressure of 140 or higher and/or a diastolic pressure of 90 or higher. Before and during the challenge Herbert had normal numbers and there was no reason for concern. 
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.
Sugar addiction – Eating and drinking foods high in sugar can have a drug-like effect on the brain and lead to sugar addiction. According to research published in the Journal of Clinical Nutrition and Metabolic Care, sugar appears to have drug-like effects, which are similar to those caused by addictive drugs. Addiction-like effects may include cravings and a loss of self-control. The research indicates that cravings for sugar may be even stronger than those for certain drugs, such as cocaine.
Due to the higher cocoa content, dark chocolate has a much richer flavor than milk chocolate. The higher the percentage of cocoa, the richer the taste. Cocoa is naturally bitter and very strong-tasting. Chocolate-makers (especially makers of milk chocolate) mellow this flavor by processes, such as alkalizing, fermenting, roasting, and adding milk and/or sugar, all of which can destroy healthy flavanols, alter our ability to use them or negate their health effects all together with unhealthy additives.
