The antioxidants vitamin C, vitamin E and beta-carotene have all been shown to have positive effects on preventing macular degeneration, or age-related vision loss/blindness. Many foods that provide these nutrients also supply antioxidants called lutein and zeaxanthin, nicknamed the eye vitamins, and found in brightly colored foods like fruits and vegetables — especially leafy greens and types that are deep orange or yellow.
The two opposing extracts were essentially left in vivo (outside of the human body) to battle each other. The resulting statistics show that chocolate's antioxidants (at least, in vivo) are extremely effective at reducing free radicals. While they may behave differently in the body, relevant studies also show that chocolate is effective at battling free radicals in vitro.
What Does It All Mean?The antioxidant powerhouses aren’t the ones most people think of. It also means that making little tweaks to the foods we already eat can impact our health in a major way. A daily dose of all-the-kale-you-can-eat will help undo some damaging influence of free radicals, but a casual dash of cinnamon across your fave breakfast bowl will do so much more.
Here’s how to have your most heart-healthy day: Cut the sugar. Studies have shown that the detrimental effects of sugar on the body could be linked to high cholesterol and death from heart disease. “High intake of sugars has been associated with an increase in a type of blood lipid called very low-density lipoprotein (VLDL) that has been associated with risk for cardiovascular disease,” Dr. Saltzman says. Sugar may also decrease HDL, the “good” cholesterol that protects against heart problems, he says. Plus, get ready for high blood pressure. “Insulin resistance may cause hypertension by its effects on the kidney, on the structure and function of arteries, and possibly on centers in the brain that contribute to blood pressure control,” he says.
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.
As we mentioned earlier, dark chocolate is loaded with antioxidant compounds that help fight the DNA damage that causes aging symptoms like wrinkles, graying hair, and disease. In fact, research shows that just a single serving of cacao contains more phenolic antioxidants than most foods and more antioxidants than many Americans get on average per day (5).
Stresses the Liver: “When we eat fructose, it goes to the liver. If liver glycogen is low, such as after a run, the fructose will be used to replenish it (3).However, most people aren’t consuming fructose after a long workout and their livers are already full of glycogen. When this happens, the liver turns the fructose into fat (2). Some of the fat gets shipped out, but part of it remains in the liver. The fat can build up over time and ultimately lead to Non-Alcoholic Fatty Liver Disease (4, 5, 6).”
Sugar does more to your brain that just foster an addiction to the sweet ingredient. Eating large amounts of sugar can affect the brain’s pathways, potentially decreasing the ability to store new information. Sugar can interfere with communication between nerve cells, potentially altering your mood, memory and processing of information. It can feel as if you are in a fog
The aim of the present study was to screen foods to identify total antioxidant capacity of fruits, vegetables, beverages, spices and herbs in addition to common everyday foods. In nutritional epidemiologic and intervention studies, the Antioxidant Food Database may be utilized to identify and rank diets and subjects with regard to antioxidant intake and as a tool in planning dietary antioxidant interventions. The database will be available online at the University of Oslo's web site.
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.
Most of the spices and herbs analyzed have particularly high antioxidant contents. Although spices and herbs contribute little weight on the dinner plate, they may still be important contributors to our antioxidant intake, especially in dietary cultures where spices and herbs are used regularly. We interpret the elevated concentration of antioxidants observed in several dried herbs compared to fresh samples, as a normal consequence of the drying process leaving most of the antioxidants intact in the dried end product. This tendency is also seen in some fruits and their dried counterparts. Thus, dried herbs and fruit are potentially excellent sources of antioxidants.
Choosing the best food sources of antioxidants can go a long way in enhancing your health and fighting disease. A class of compounds found in a wide range of foods (especially plant-derived foods), antioxidants help protect against the damaging effects of free radicals. It's thought that increasing your intake of the best food sources of antioxidants can help fend off a host of major health conditions, such as heart disease, diabetes, Alzheimer's disease, and some forms of cancer.
An ongoing 40-year study on the effects of chocolate on cognitive function was recently finished. The study used data from the beginning of the study and compared it through cross-sectional study. This might not mean that chocolate makes people smarter—perhaps smart people happen to eat chocolate. Regardless, the study also concluded that all the types of intelligence measured previously were increased by chocolate consumption—along with spoken word recall.
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.

For another berry rich in antioxidant power, strawberries are an excellent choice. These berries are another one of the most highly concentrated antioxidant fruits. The antioxidants found in strawberries have been shown to fight carcinogens and LDL, cholesterol that is known to cause heart disease. Strawberries contain, anthocyanins, the antioxidants that protect against cardiovascular diseases. They are also a great source of vitamin C, which protects your body’s cells from free radical damage.
But dark chocolate’s superfood status is likely a bit overblown, says Alan Aragon, M.S., Men’s Health nutrition advisor. “Dark chocolate just happens to have beneficial compounds that favorably influence various health parameters when consumed judiciously.” In this case, judiciously means this: consume in moderation. Since chocolate is energy-dense (read: it’s got 150 to 170 calories per ounce), scarf it down indiscriminately and you’ll easily wind up taking down excess calories and weighing down the scale, he notes.
Flavonoids have been shown to offer significant protection for neurons in your brain and nervous system. Specifically, they reduce neuroinflammation, which has been found to be a major cause of the development of Parkinson’s and Alzheimer’s disease. In addition, their ability to increase cerebral blood flow encourages the growth of new neurons in the hippocampus, which processes memory (13).
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.
