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.
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!
Studies show that the darker the chocolate, the better. Eat only less-processed chocolate that contains at least 65 percent cacao, recommends Joy DuBost, PhD, RD, an American Dietetic Association spokeswoman. Not only does dark chocolate have a higher concentration of antioxidants than milk chocolate, but milk chocolate is also higher in added sugar and unhealthy fats. Still, the daily dose of antioxidants in dark chocolate doesn’t give you license to indulge in a dessert free-for-all — dark chocolate is still loaded with fat and calories — so eat a max of 1 to 2 ounces a day. If you do, research says you’ll reap these 9 benefits.
These antioxidants are believed to be easily transported around the body, especially to the delicate parts of the eyes called the macula and the lens. In fact, there are more than 600 different types of carotenoids found in nature, but only about 20 make their way into the eyes. (4) Of those 20, lutein and zeaxanthin are the only two that are deposited in high quantities into the macular portion of the eyes, which is one of the earliest to be damaged during aging.
The protective effect of antioxidants continues to be studied around the world. For instance, men who eat plenty of the antioxidant lycopene (found in tomatoes) may be less likely than other men to develop prostate cancer. Lutein, found in spinach and corn, has been linked to a lower incidence of eye lens degeneration and associated blindness in the elderly. Flavonoids, such as the tea catechins found in green tea, are believed to contribute to the low rates of heart disease in Japan.
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.
In the nuts and seeds category we analyzed 90 different products, with antioxidant contents varying from 0.03 mmol/100 g in poppy seeds to 33.3 mmol/100 g in walnuts, with pellicle and purchased with nut shell intact. Pecans with pellicle, sunflower seeds and chestnuts with pellicle, have mean antioxidant content in the range of 4.7 to 8.5 mmol/100 g (Table (Table3).3). Walnuts, chestnuts, peanuts, hazelnuts and almonds have higher values when analyzed with the pellicle intact compared to without pellicle.
