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).
This tiny powerhouse is rich in beta-carotene, an antioxidant that protects against lung cancer and helps maintain healthy skin, hair, nails, gums, glands, bones, and teeth. It’s also a good source of vitamin E, which may help prevent heart attacks, stokes, and lower the risk of death from bladder cancer. Here are the things every woman should know about bladder cancer.
Dark chocolate contains 50-90% cocoa solids, cocoa butter, and sugar, whereas milk chocolate contains anywhere from 10-50% cocoa solids, cocoa butter, milk in some form, and sugar. Though dark chocolate should not contain milk, there may be traces of milk from cross-contamination during processing, as the same machinery is often used to produce milk and dark chocolate. Lower quality chocolates may also add butter fat, vegetable oils, or artificial colors or flavors. White chocolate does not contain any cocoa solids and is made simply of cocoa butter, sugar, and milk.

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.
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.
Scientists believe when we eat plant foods (luscious dark chocolate comes from the cacao plant) rich in flavonoids and antioxidants, their benefits are passed on to us. Antioxidants protect our cells from damage caused by free radicals, which are unstable oxygen molecules thought to be responsible for aging and some diseases. “When you have too many free radicals in your body, they start to attack your cells, and that can lead, over time, to low-grade inflammation and to some diseases — cancer, heart disease, and Alzheimer’s,” DuBost says.
What do free radicals do exactly, and why are they so destructive? The body uses antioxidants to prevent itself from the damage caused by oxygen. Electrons exist in pairs; free radicals are missing an electron. This is their weapon of sorts. They “react” with just about anything they come into contact with, robbing cells and compounds of one of their electrons. This makes the affected cell or compound unable to function and turns some cells into “electron-seeking muggers,” leading to a chain reaction in the body and the proliferation of free radicals. Free radicals then damage DNA, cellular membranes and enzymes.
Sugar alcohols like xylitol, glycerol, sorbitol, maltitol, mannitol, and erythritol are neither sugars nor alcohols but are becoming increasingly popular as sweeteners. They are incompletely absorbed from your small intestine, for the most part, so they provide fewer calories than sugar but often cause problems with bloating, diarrhea, and flatulence.
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.
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.
“Dr. David Reuben, author of Everything You Always Wanted to Know About Nutrition says, “white refined sugar-is not a food. It is a pure chemical extracted from plant sources, purer in fact than cocaine, which it resembles in many ways. Its true name is sucrose and its chemical formula is C12H22O11. It has 12 carbon atoms, 22 hydrogen atoms, 11 oxygen atoms, and absolutely nothing else to offer.” …The chemical formula for cocaine is C17H21NO4. Sugar’s formula again is C12H22O11. For all practical purposes, the difference is that sugar is missing the “N”, or nitrogen atom.”
Things get a little bumpy when the liver becomes full of glycogen due to excessive refined sugar consumption. When you eat too much sugar, the fructose levels build up, and the liver eventually turns them to fat. That fat can get stuck in the liver, which causes non-alcoholic fatty liver. In other words, excessive sugar consumption can eventually have the same
The samples were classified into 24 different categories covering products from the plant kingdom, products from the animal kingdom and mixed food products. Information about sample processing (raw, cooked, dried etc), if any, was included, along with all sample specifications, i.e. product name, brand name, where the product/sample was procured and country of origin. The product information in the database was collected from the packing of the product, from supplier or purchaser. When this information was not available or the samples were handpicked, only country of origin is presented. Each sample is assigned to only one category. The classification was done according to information from the supplier or purchaser, or according to common traditional use of the food. Some foods may therefore be categorized otherwise in other food cultures. For products in the categories "Herbal/traditional plant medicine" and "Vitamin and dietary Supplements" some products may rightfully be classified as both an herbal medicine and a supplement, but are still assigned to only one category. All berries, fruits, and vegetables were fresh samples unless otherwise noted in the database. The Antioxidant Food Table contains 3139 samples. About 1300 of these samples have been published before [16,17,28] but for comparison and completeness we have included them in the present publication. All individual samples previously published are identified by a comment in the Antioxidant Food Table. The categories and products in the database are presented in alphabetic order. Information about brand names and product trademarks does not imply endorsement by the authors, and are reported as descriptive information for research applications only. The Antioxidant Food Table will in the future be available online as a searchable database. In addition to the products mentioned in this paper, other foods will in the future be analyzed and incorporated into the online version, which will be posted on the University of Oslo's web site.
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.
Many of us take the bait at the word “antioxidant,” buying health and beauty products without knowing exactly how these mysterious compounds actually benefit us. Let's clear that up: “Antioxidants act like little bodyguards to protect our cells from damage that can lead to premature aging and disease,” explains Cynthia Sass, Health’s contributing nutrition editor. They neutralize harmful free radicals, molecules that play a role in cancer, Alzheimer’s, heart disease, and more.
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.
Most of the breakfast cereals have antioxidant content in the range of 0.5 to 2.25 mmol/100 g, while 4 single products are above this range. Among grains and grain products, buckwheat, millet and barley flours are the flours with the highest antioxidant values in our study (Table (Table3),3), while crisp bread and whole meal bread with fiber are the grain products containing most antioxidants. Beans and lentils have mean antioxidant values ranging from 0.1 to 1.97 mmol/100 g. Different types of rice have antioxidant values between 0.01 and 0.36 mmol/100 g.
Flavanols are the main type of flavonoid found in dark chocolate. According to Cleveland Clinic, research has shown that flavanols have a very positive effect on heart health by helping lower blood pressure and improving blood flow to the heart as well as the brain. Dark chocolates flavanols can also help make blood platelets less sticky and able to clot, which reduces the risk of blood clots and stroke. (5)

Another study published in 2015 titled followed the health of over 20,000 people for 11 years. The study concluded that “cumulative evidence suggests that higher chocolate intake is associated with a lower risk of future cardiovascular events” and that “there does not appear to be any evidence to say that chocolate should be avoided in those who are concerned about cardiovascular risk.” Among subjects who consumed the most chocolate, 12 percent developed or died of cardiovascular disease during the study compared to 17.4 percent of those who didn’t eat chocolate. (7) This doesn’t give anyone license to eat a chocolate bar each day, but it’s impressive that this large and lengthy study does appear to show a positive connection between chocolate consumption and heart health.
