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 , coffee , tea [54,75,76], red wine [77-79] and cocoa . 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 . 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.
…Consumption of processed foods (which are laced with sugar) cost the American public more than $54 billion in dental bills each year, so the dental industry reaps huge profits from the programmed addiction of the public to sugar products. …Today we have a nation that is addicted to sugar. In 1915, the national average of sugar consumption (per year) was around 15 to 20 pounds per person. Today the average person consumes his/her weight in sugar, plus over 20 pounds of corn syrup. To add more horrors to these facts there are some people that use no sweets and some who use much less than the average figure, which means that there is a percentage of the population that consume a great deal more refined sugar than their body weight. The human body cannot tolerate this large amount of refined carbohydrates. The vital organs in the body are actually damaged by this gross intake of sugar.
Can't remember where you put your keys or why you walked into a particular room? Chocolate may help: Recent research suggests that antioxidants called flavanols found in cocoa can helpimprove function in the area of the brain responsible for this type of age-related memory loss. Participants in the study were placed on a special diet high in raw cocoa flavanols called epicatechin. At the end of the three-month period they scored significantly higher on memory tests than the control group.
Plants are humanity's greatest ally in the fight against climate change. Plants soak up carbon dioxide and turn it into leaves and branches. The more trees humans plant, the less heat-trapping carbon pollution in the air. Unfortunately, plants require a lot of water and land, so much that humans might need a new to find a new ally to help draw down all that carbon.
People with high levels of sugar consumption are much more likely to become obese or overweight, no matter what age — even children. In fact, children who drink a serving of sugar-sweetened beverage daily have a 60 percent greater chance of become obese. This sets your child up for a lifetime of being overweight or obese — plus, all of the potential health
They work to protect the cells by damage caused by oxidants. Oxidants, on the other hand, are free radicals that your body produces to defend itself against bacteria and viruses. When they become too many in number, they may start attacking and harming the cells and even put us at the risk of serious diseases like heart trouble and cancer. You may also encounter oxidants from the external environment from pollutants, smoke or alcohol. Antioxidants help the body by neutralising and removing these oxidants from your bloodstream.
While we all like to indulge once in a while, foods that quickly affect blood sugar contribute to a greater risk of obesity, heart disease, and diabetes.1 Emerging research also suggests connections between these high-glycemic diets and various forms of cancer.2,3,4 These effects are often a result of added sugars working in your body, so be sure to read those nutrition labels.
Fish provides powerful omega-3 fatty acids. Evidence suggests that omega-3s, particularly those coming from fish, may help prevent inflammatory diseases, such as coronary heart disease. Although all fish have some omega-3s, the stars include sardines, salmon, oysters, mackerel, tuna steak, wild rainbow trout, shark steak, albacore tuna, and herring.
What about heavy metals? In recent years there has been press about Lead and Cadmium levels in chocolate. This has nothing to do with manufacturing, but the presence of these metals in soils where cacao is grown. To keep in context, dietary cadmium exposure can come from all kinds of foods – cereals, vegetables, nuts, etc. Given the small volumes of dark chocolate that we eat, cadmium in chocolate should not be viewed as a major concern.
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.
The research included information that animal studies have found the hippocampus, which is an area in the brain associated with memory, may be affected by refined sugar. Two studies were conducted in the published report. In the first study, participants that self-reported eating a high-sugar diet had poorer performance on hippocampal related memory tasks. In the second study, the results were replicated. The second study also revealed that the effect of high sugar consumption on memory appears to be directly related to the hippocampal region and no other areas which may also affect memory, such as the prefrontal cortex.
But these benefits could have an even bigger impact: Flavonoids foundin dark chocolate may someday be useful in potentially treating neurodegenerative diseases such as Alzheimer’s. One study in the Journal of Alzheimer’s Disease found an association between eating chocolate and reduced risk of cognitive decline, perhaps due to protective effects of the cocoa flavanols.
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.
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.
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.
One of the effects of sugar on the body is that it could make your depression worse, according to research. “I like to tell my patients there’s a truth to the saying, ‘You are what you eat,’” says psychologist Deborah Serani, PsyD, award-winning author of Depression in Later Life. “High levels of sugar in the form of simple carbohydrates leads to spikes and crashes in glucose levels, which can worsen mood, increase irritability, agitation, irregular sleeping, and increase inflammation.” Instead, munch on lean protein, complex carbs, and foods with omega-3s, folate, and B vitamins.
My kids typically make good food choices on their own and have become rather adventurous eaters since they aren’t restricted or expected to only consume chicken fingers or hamburgers when we aren’t at home. For instance, my two year old loves broccoli, olives, sardines and other healthy foods. Make the good foods readily available and make the unhealthy ones few and far between…
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.
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.
Fructose—the sugar that naturally occurs in fruit and is a component, with glucose, of high fructose corn syrup (HFCS) and table sugar—lights up the brain's reward center, says pediatric endocrinologist Robert Lustig, MD, of UCSF Benioff Children's Hospital in San Francisco. But over time, a diet packed with fructose (especially from HFCS) can make it tougher to learn and remember, animal research suggests. To stay in peak mental shape, try sticking with savory snacks.

Your dark chocolate of choice should also be made from cocoa butter, not palm and/or coconut oils. Also look out for any hydrogenated or partially hydrogenated oils in the ingredient list. Now that huge commercial chocolate makers are responding to the love of dark chocolate and making their own versions, you have to be careful. A label that reads “dark chocolate” doesn’t automatically make it a healthy choice. The healthiest or best dark chocolate is made from cacao or cocoa that’s organic, minimally processed and definitely not dutched.
Prevent diabetes – Dark chocolate reduces insulin resistance. In a small Italian study, participants who ate a candy bar’s worth of dark chocolate once a day for 15 days saw their potential for insulin resistance drop by nearly half. The flavonoids, which are the antioxidants in dark chocolate, create a gas called nitric oxide that helps control insulin sensitivity.
The "glycemic index" is a measure of how a given food affects blood-glucose levels, with each food being assigned a numbered rating. The lower the rating, the slower the absorption and digestion process, which provides a more gradual, healthier infusion of sugars into the bloodstream. On the other hand, a high rating means that blood-glucose levels are increased quickly, which stimulates the pancreas to secrete insulin to drop blood-sugar levels. These rapid fluctuations of blood-sugar levels are not healthy because of the stress they place on the body.
Sweets can lower levels of the stress hormone cortisol in the near term, research shows. But continue OD'ing on sugary refined carbs and your risk of insulin resistance, which stresses the body from the inside, goes up. To find your calm, sweat instead: "Exercise is the best treatment for stress. It makes you feel good and reduces cortisol," says Dr. Lustig.
“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.”
To melt: Dark chocolate should be heated gradually to prevent scorching. This may be done on a stove top on low heat or in a microwave oven on 50% power. Break chocolate into smaller pieces and place in pan or microwave to heat. Stir continually (or after each minute) to ensure even heating. Drizzle 1-2 tablespoons of melted dark chocolate over oatmeal, yogurt, or fresh fruit for an easy healthful snack.
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)
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 . 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.
