Calorie Restriction

Calorie restriction refers to reducing calorie intake to achieve better health. Calories are a measure of the energy released when the body burns any fuel including fat, protein, carbohydrates, and alcohol. Many studies have indicated that excessive calorie intake may result in various health problems such as cancer, heart disease, aging, and obesity. One of the reason that excessive calorie intake cause those health problems is that it facilitate free radical production in the body. Free radicals are considered to be a major causative factor for cancer, heart disease, and aging. Thus proper calorie restriction is an effective way to achieve good health and longevity. According to experts, certain things need to be considered in order to have success with calorie restriction:


Eat a diet with balanced nutrition but low in calories. Balanced nutrition is very important in maintaining your overall health.
Cut calories gradually and comfortably, so you lose bodily weight very slowly. Avoid extremely low-calorie diets, which may actually harm you instead of helping you.
Eat whole foods that have the most nutrients and other healthy components for the least calories, the best of which are fruits and vegetables.
Don’t go on a restricted-calorie diet designed to postpone aging and age-related diseases before you are fully grown as it may stunt your growth.

Health Benefits of Broccoli

Health Benefits of BroccoliScientific Name: Brassica aleracea

Biological Background: Broccoli is a dark-green vegetable with small, tight heads (curds) mounted on stem-like buds, and is a member of Brassica family of the Cruciferous vegetables. It is one of the most popular vegetables and was originated in Italy.

Nutritional Information: One cup of chopped and cooked broccoli (146 g) provides 46 calories, 4.6 g protein, 8.7 g carbohydrates, 6.4 g fiber, 178 g calcium, 1.8 mg iron, 220 RE vitamin A, 0.13 mg thiamin, 0.32 mg riboflavin, 1.18 mg niacin, 98 mg vitamin C.


Pharmacological Information: Broccoli is a spectacular and unique package of versatile disease fighters and abundant in numerous strong, well-known phytochemicals and antioxidants, including indoles, isothiocyanates, quercetin, glutathione, beta carotene, vitaminC, folate, lutein, glucarate, and glutathione. Broccoli is extremely strong in anticancer activity, particularly against lung, colon, and breast cancers. Like other cruciferous vegetables, it speeds up the removal of estrogen from the body, helping suppress breast cancer. Broccoli is rich in cholesterol-reducing fiber and has antiviral and antiulcer activity. It is a super source of chromium that helps regulate insulin and bloodsugar. Broccoli is also a good source of calcium, thus help fight osteoporosis. However, brocoli is one of the leading intestinal gas producers.

Eating Tips: Heavy cooking and processing destroy some of the anti oxidants and phytochemicals such as indoles and glutathione. Eat raw or lightly cooked as in microwave and stir-fry. To reduce its gas production, eat broccoli with ginger or garlic.
