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.
Cherries have been touted as the new wonder fruit, and based on their antioxidant content we can see why! Cherries are rich in the flavonoids, isoqueritrin and queritrin, which act as antioxidants and work to eliminate byproducts of oxidative stress, therefore slowing down the aging process. Cherries are also loaded with Queritrin, a flavonoid believed to be one of the most potent anticancer agents.
You know saturated fats are bad for your heart, but sugar can also have a damaging effect on your cardiac health. A high intake of added sugars seems to increase the risk of cardiovascular disease mortality. One study that took place over 15 years indicated that people who consume 25 percent or more of calories from sugar were more than twice as likely as those who consumed less than 10 percent of calories from sugar to die from heart disease. Simply eating a high-sugar diet significantly increases your risk of heart problems.
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).
Some nutrients are destroyed in the process of making chocolate available for the general market. Make sure the chocolate you buy is within the healthy range. Check the label: Chocolate with a 60 percent or higher cocoa content is packed full of nutrients and antioxidants. Often called bittersweet, it has minimal sugar. The best way to get all the nutrients from chocolate is simply to use unsweetened cocoa nibs. The bitter, crunchy, seed-like snack isn't the best-tasting treat, but its nutritional profile makes it worthwhile.
Another side effect of inflammation: It may make your skin age faster. Sugar attaches to proteins in your bloodstream and creates harmful molecules called “AGEs,” or advanced glycation end products. These molecules do exactly what they sound like they do: age your skin. They have been shown to damage collagen and elastin in your skin -- protein fibers that keep your skin firm and youthful. The result? Wrinkles and saggy skin.
While it’s good for your brain and digestive health, dark chocolate can benefit your heart even more. Research shows that the flavonoids naturally found in chocolate can help lower levels of bad LDL cholesterol. Flavonoids can also significantly decrease systolic blood pressure in healthy older adults. Dark chocolate has also been found to improve insulin resistance and endothelial dysfunction, both of which have a positive effect on the heart. In fact, according to a study published in JAMA Internal Medicine, in individuals who suffered a previous heart attack, eating chocolate twice a week compared with never eating chocolate has been shown to lower the risk of death from heart disease by 66 percent.
Another possible allergen to watch out for in dark chocolate (even organic brands) is soy lecithin, which is commonly added as an emulsifying agent. Soy lecithin does contain trace amounts of soy proteins, and these have been found to include soy allergens. However, soy lecithin does not appear to contain sufficient soy protein residues to induce allergic reactions in the majority of soy-allergic consumers. (26)
Juicy and tart Montmorency cherries are your best source of the antioxidant melatonin. Other cherries have it, too, but Montmorency has the most. Melatonin protects the skin against ultraviolet radiation. Researchers have discovered that this powerful little nutrient also helps repair sunburned skin, since it stimulates new skin-cell growth. Cherries are also packed with vitamin C, which is needed to build collagen—your skin’s natural “scaffolding” and a wrinkle preventer. Here are some more foods proven to fight wrinkles (and two you should avoid).
Hence, cancer therapies should attempt to regulate blood-glucose levels through diet, supplements, exercise, medication when necessary, gradual weight loss and stress reduction. Since cancer cells derive most of their energy from anaerobic glycolysis, the goal is not to eliminate sugars or carbohydrates entirely from the diet but rather to control blood-glucose within a narrow range to help starve the cancer cells and boost immune function.
The occasional candy or cookie can give you a quick burst of energy (or “sugar high”) by raising your blood sugar levels fast. When your levels drop as your cells absorb the sugar, you may feel jittery and anxious (a.k.a. the dreaded “sugar crash”). But if you’re reaching into the candy jar too often, sugar starts to have an effect on your mood beyond that 3 p.m. slump: Studies have linked a high sugar intake to a greater risk of depression in adults.
Just empty and quickly digested calories that actually pull minerals from the body during digestion. It creates a hormone cascade when consumed that starts a positive feedback loop in the body to encourage more consumption. In a time when food was scarce and needed to be contained in large amounts in the summer when available to survive the winter, this was a good thing. In today’s world of constant access to processed foods, this natural biological purpose highlights one of the negative effects of sugar. Here’s why:
Before you swap refined sugar for artificial sweeteners, you may want to keep reading. Artificial sweeteners also appear to have several negative effects on the brain. Sweeteners, such as aspartame, sucralose, and saccharin, are not healthy alternatives to sugar. These sweeteners are in a variety of foods and drinks, such as diet soda, sugar-free snacks, and energy drinks.
Along the way, the benefits of dark chocolate have pushed its popularity. You’ve probably seen dark chocolate listed among “must-eat healthy foods” in compilations written by various nutrition experts. Yet depending on how it’s made, dark chocolate also can be high in calories, fat, sugar, and preservatives. So, what’s the real deal? Is dark chocolate healthy?
According research published in Free Radical Biology & Medicine, the official journal of the Society for Redox Biology and Medicine along with the Society of Free Radical Research-Europe, proteins are often targeted by reactive oxygen species, also known as oxidants. (1a) We know how important proteins are to health, so protecting them is just one of the many reasons antioxidants and antioxidant foods are important.
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.
Weight gain: Some studies suggest that chocolate consumption is linked to lower body mass index (BMI) and central body fat. However, chocolate can have a high calorie count due to its sugar and fat content. Anyone who is trying to slim down or maintain their weight should limit their chocolate consumption and check the label of their favorite product.
The bottom line is, try to wean yourself from sugar. And, learn to enjoy the truly natural sweetness of fruits and berries. And, if you must use sweeteners to make your food more interesting, there are many alternatives from which to choose. However, if your goal is to be as healthy as you can, your best choice is stevia. Moderation is key. Make the best choices you can most of the time, and your life can be pretty sweet.
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.
In the brain, excess sugar impairs both our cognitive skills and our self-control (having a little sugar stimulates a craving for more). Sugar has drug-like effects in the reward center of the brain. Scientists have proposed that sweet foods—along with salty and fatty foods—can produce addiction-like effects in the human brain, driving loss of self-control, overeating, and subsequent weight gain.
Enter milk, sugar, and butter—good for your taste buds, not always good for your health. Besides adding calories, these can dilute the benefits of cacao. So snack smart: Stick to healthy chocolate with at least 70 percent cacao (or cocoa, which is cacao in its roasted, ground form). As long as the content is that high, says Mary Engler, Ph.D., a professor of physiological nursing at the University of California at San Francisco, you can reap the benefits from eating only small amounts. Because of its high fat and sugar content, limit yourself to 7 ounces, or about four dark chocolate bars, a week.
