Did you know up to 68 percent of people might not get the proper amounts of magnesium, an important player in over 300 bodily processes? Dark chocolate is a solid source of the mineral, says Aragon. About 3.5 ounces of dark chocolate, two squares of that Trader Joe’s dark chocolate, packs about 228 mg magnesium, putting you well on your way to the 400 mg recommended a day.
Research shows that high antioxidant foods counteract the effects of oxidative stress. In fact, there are hundreds of different substances that act as antioxidants. The most recognizable among them are beta-carotene (a precursor to vitamin A), vitamin C, vitamin E, selenium and manganese, glutathione, melatonin, coenzyme Q10, lipoic acid, flavonoids, and phytoestrogens.
Cranberries are not just another staple on the American Holiday table. They pack some serious antioxidant punch and are also well known for their beneficial effect on preventing urinary tract infections. Try 100% cranberry juice diluted in water or sparkling water for a refreshing, tart drink, or add some unsweetened dried cranberries to your trail mix.
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.
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.
