Because you’re not getting any real nutrients when you eat sugar, you may still feel hungry. One Australian study found that higher refined sugar intake was associated with an inability to realize you’re full. Plus, with sweet drinks, “calories from sugar in liquid form are not thought to be satiating, and people are not able to fully account for the calories that were consumed in liquid form with a compensatory reduction in calories at subsequent meals,” Dr. Malik says. So, you may end up eating more calories overall. Here are 50 “healthy” snacks that are secretly bad for you.
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.

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!
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.
The deep red color of cherries is due to high levels of anthocyanins, also found in blueberries, which reduce inflammation and help lower cholesterol. Canned tart or sour cherries and dried sweet cherries both scored higher for antioxidants than the sweet, fresh variety. Tart cherries pack an added bonus: melatonin, which might help regulate sleep cycles.
But there are lesser-known reasons you should indulge in the (bitter)sweet stuff. Dark chocolate has been scientifically proven to keep your brain sharp, your ticker ticking and your skin shielded from the sun’s harmful rays (yes, really). Dark chocolate can be the key to beating that midday slump, accoriding to a new study from Northern Arizona University found.
For a report published in the Journal of Agricultural and Food Chemistry in 2004, scientists from the U.S. Department of Agriculture (USDA) performed what is considered to be the most comprehensive analysis of the antioxidant content of commonly consumed foods. The USDA scientists ranked these foods according to their total antioxidant capacity, which is a measure of the antioxidants' ability to neutralize free radicals.
The new study is more complete and accurate (thanks to updated technology) than previous USDA antioxidant data and includes more foods than the previous study, the researchers say. They analyzed antioxidant levels in over 100 different foods, including fruits and vegetables. In addition, the new study includes data on spices and nuts for the first time.
Antioxidants, such as vitamins C and E, and carotenoids, may help protect cells from damage caused by free radicals. Other naturally occurring antioxidants include flavonoids, tannins, phenols and lignans. Plant-based foods are the best sources. These include fruits, vegetables and their juices, whole-grain products, nuts, seeds, herbs and spices, and even cocoa.
They tested this by giving subjects different cough medicines. One group received common cough medicine with codeine; the second group received a solution of theobromine and the third group was placebo. They were exposed to capsaicin (the chemical responsible for making chili peppers spicy.) Their intention was to see how much capsaicin was required to induce five coughs. Having one's lungs exposed to capsaicin will usually cause even the most hardened chili-head to break into a coughing fit.
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.
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.
Elevated blood glucose harms blood vessels. Blood vessel damage is the major cause of the vascular complications of diabetes, leading to other problems, such as damage to blood vessels in the brain and eyes causing retinopathy. Studies of long-term diabetics show progressive brain damage leading to deficits in learning, memory, motor speed, and other cognitive functions.
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.”
As preventive cardiologist Dr. Suzanne Steinbaum of Lenox Hill Hospital in New York City says, “When looking for a sweet snack, a square of dark chocolate might, in fact, be your healthiest choice!” (2) Let’s look at exactly why this expert medical opinion really does ring true and why a little dark chocolate is more than just a tasty treat — with health benefits of dark chocolate that include protection against disease and improved brain and heart health.
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.
not always easy to spot sugar on the ingredients list, even when it is added. More than 60 names appear on labels, all of which mean sugar was added to the product. It’s no wonder cutting sugar is a challenge. Anything with sugar, syrup or sweetener as part of the name qualifies. Look for “ose” words, such as fructose, glucose and sucrose, for other potential sugar sources. Look for lower-sugar versions of the foods you consume.
Among the fruits, vegetables and nuts analyzed, 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.
Researchers from the University of Copenhagen found that dark chocolate is far more filling, offering more of a feeling of satiety than its lighter-colored sibling. That is, dark chocolate lessens cravings for sweet, salty, and fatty foods. So if indulging in a bit of healthy dark chocolate should not only make it easy for you to stick to the small portion recommended for optimal health, but it should make it easier for you to stick to your diet in general. Jackpot!
Dark chocolate is also called semisweet chocolate while extra dark chocolate is often considered the same as bittersweet, although the ratio of cocoa butter to solids may vary between the varieties. (14) According to the FDA, semisweet chocolate or bittersweet chocolate is a sweet chocolate that contains no less than 35 percent (by weight) of pure cocoa. (15) Semisweet and bittersweet are both commonly used in baking, and although the FDA defines them in the same way, bittersweet chocolate typically has a deeper flavor and less sweetness than semisweet chocolate. (16) Unsweetened or baker’s chocolate is usually almost 100 percent cocoa with no sweetness whatsoever.
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.
Good news for all chocolate lovers! Chocolate is actually quite healthy so no need to feel guilty indulging in your chocolate love every now and then. Dark chocolates and cocoa pack a big antioxidant punch and are rich in flavanols and polyphenols. A popular study conducted by Harvard experts and published in the online Journal Heart suggests that is actually good for your heart especially, the one with 70% cocoa. Too much chocolate can, of course, add to you daily calorific intake so moderation is the key here.
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.
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.
Because refined dietary sugars lack minerals and vitamins, they must draw upon the body's micro-nutrient stores in order to be metabolized into the system. When these storehouses are depleted, metabolization of cholesterol and fatty acid is impeded, contributing to higher blood serum triglycerides, cholesterol, promoting obesity due to higher fatty acid storage around organs and in sub-cutaneous tissue folds.
An unhealthy liver is just one of the many effects of sugar on the body, especially when it’s consumed in large amounts. “Fructose is metabolized in the liver, and consuming too much can lead to the production of fat in the liver, which is another path to adverse metabolic health,” Dr. Malik says. According to the University of California San Francisco, rates of non-alcoholic fatty liver disease, as well as scarring of the liver, have doubled since 1980. Follow these 9 tricks to reverse a sugar binge.
The ORAC scores above are based on weight. This means that it might not be practical to eat high amounts of all of these antioxidant foods. Other high antioxidant foods not listed above, which are still great sources and highly beneficial, include common foods like tomatoes, carrots, pumpkin seeds, sweet potatoes, pomegranates, strawberries, kale, broccoli, grapes or red wine, squash, and wild-caught salmon. Try to consume at least three to four servings daily of these high antioxidant foods (even more is better) for optimal health.
To avoid overindulging in dark chocolate yet obtain the benefits of dark chocolate, it’s a smart idea to eat a little piece by itself after a solid meal or include it in a recipe. If you’re sensitive to caffeine or looking to avoid caffeine entirely, it’s important to know that there are measurable amounts of caffeine in dark chocolate. Caffeine side effects can include nervousness, increased urination, sleeplessness and a rapid heartbeat, all reasons to avoid caffeine overdose.
In moderation (one ounce or less per day), dark chocolate has been shown to improve so many common and chronic health problems. With all of its natural and health-promoting components (like flavonoids, polyphenols and flavanols), dark chocolate is an antioxidant powerhouse and a superfood that’s truly a joy to eat. It’s been shown to boost heart and brain health, along with fight disease — just some of the many benefits of dark chocolate.
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.
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.
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.
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.
Chocolate’s lengthy history is believed to go all the way back to 1900 B.C. This is when the the Aztec civilization believed that cacao seeds were a gift of Quetzalcoatl, the god of wisdom. They used the seeds to prepare a bitter, frothy beverage that also included spices, wine or corn puree. (22) It was very different from today’s super sweet milk chocolate treats but closer to a very minimally processed dark chocolate made from raw cacao.
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.
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.
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.
When you eat excess sugar, the extra insulin in your bloodstream can affect your arteries, part of your body’s circulatory system. It causes their walls to grow faster than normal and get tense, which adds stress to your heart and damages it over time. This can lead to heart disease, heart attacks, and strokes. Research also suggests that eating less sugar can help lower blood pressure, a major risk factor for heart disease. Plus, people who eat a lot of added sugar (where at least 25% of their calories comes from added sugar) are twice as likely to die of heart disease as those whose diets include less than 10% of total calories from added sugar.
Dark chocolate may have something in common with carrots: Researchers from the University of Reading in England tested the eyesight of 30 healthy adults, 18 to 25 years old, after they ate white and dark chocolates. The subjects performed better on vision tests after eating the dark chocolate. It could be that the flavanols in dark chocolate, which improve blood flow to the brain, improve blood flow to the retina as well — and white chocolate doesn’t have nearly the same amount of flavanols as dark chocolate.
There is increasing evidence that antioxidants are more effective when obtained from whole foods, rather than isolated from a food and presented in tablet form – and some supplements can actually increase cancer risk. For instance, vitamin A (beta-carotene) has been associated with a reduced risk of certain cancers, but an increase in others, such as lung cancer in smokers, if vitamin A is purified from foodstuffs.
