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.

Foods high in refined sugar are claimed to exacerbate hyperactivity and increase aggressive behavior. Controlled studies have failed to confirm any effect on hyperactivity and effects on inattention have been equivocal. Possible effect on aggressive behavior has received little study. This study assessed cognitive attention and aggressive behavior immediately following an acute ingestion of sugar compared with saccharin and aspartame-sweetened placebos in 17 subjects with attention deficit disorder with hyperactivity compared with 9 age-matched control subjects. The sugar and placebo challenges were given with a breakfast high in carbohydrate. Although the children with attention deficit disorder with hyperactivity were significantly more aggressive than the control subjects, there were no significant effects of sugar or either placebo on the aggressive behavior of either group. However, inattention, as measured by a continuous performance task, increased only in the attention deficit disorder with hyperactivity group following sugar, but not saccharin or aspartame. This result is of questionable clinical significance inasmuch as aggressive behavior was unchanged. The finding may be due to the combination of the sugar challenge with a high-carbohydrate breakfast. These findings should be replicated and any possible clinical significance should be documented before any dietary recommendations can be made.

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.
The research is piling up that soda is bad for your brain, as are other added sugars. An animal study from Oregon State University found that a high-sugar diet led to cognitive impairments, including memory problems. And a UK study recently found the “tipping point” at which blood sugar negatively affects the progression of Alzheimer’s. “Excess sugar is well known to be bad for us when it comes to diabetes and obesity, but this potential link with Alzheimer’s disease is yet another reason that we should be controlling our sugar intake in our diets,” study author Dr. Omar Kassaar of the University of Bath said in a press release.
Cocoa is rich in plant chemicals called flavanols that may help to protect the heart. Dark chocolate contains up to 2-3 times more flavanol-rich cocoa solids than milk chocolate. Flavanols have been shown to support the production of nitric oxide (NO) in the endolethium (the inner cell lining of blood vessels) that helps to relax the blood vessels and improve blood flow, thereby lowering blood pressure. [1,2] Flavanols in chocolate can increase insulin sensitivity in short term studies; in the long run this could reduce risk of diabetes. [3,4]
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).
Evidence that dark chocolate may play a role in cancer prevention is limited but growing. Some preliminary studies on three continents — Europe, Asia, and North America — have shown that people who eat many flavonoids or a lot of antioxidant-rich chocolate develop fewer cancers than those who don’t consume them. Of the many flavonoids in chocolate, two in particular, epicatechin and quercetin, are believed to be responsible for the cancer-fighting properties.
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)
Vitamin A and C have been connected to a decrease in the appearance of wrinkles and skin dryness. Vitamin C, specifically, is a powerful antioxidant that can help reduce the effect of oxidative damage caused by pollution, stress or poor diet. Vitamin A deficiency has also been linked to skin dryness, scaling and follicular thickening of the skin. Similarly to how free radicals damage surface skin cells, keratinization of the skin, when the epithelial cells lose their moisture and become hard and dry, can occur in the mucous membranes of the respiratory, gastrointestinal tract and urinary tract.
