Food Therapy - Dried Peas and Weight loss

Dried peas is a small but nutritionally mighty member of the legume family, genus Pisum belongs to the family Fabaceae. It has a healthy source of protein, fibers, vitamins and minerals that is good for everyone diet.
Obesity is defined as a medical condition of excess body fat has accumulated overtime, while overweight is a condition of excess body weight relatively to the height. According to the Body Mass Index(BMI), a BMI between 25 to 29.9 is considered over weight, while a BMI of over 30 is an indication of obesity. According to the statistic, 68% of American population are either overweight or obese.

The Nutrients and Chemical constituents
1. Carbohydrates
2. Dietary fiber
3. Fat
4. Protein
5. Vitamin A ( Beta carotene, lutein and zeaxanthin)
6. B vitamins
7. Vitamin C
8. Calcium
9. Iron
10. Magnesium
11. Phosphorus
12. Potassium
13. Zinc Beside it main component of  Polyphenolic compound , it also saponin pisatin, L-pipecolic acid, glycoside-Pisatoside, tocopherols, cerebroside, etc.

The benefits
The prevalence of obesity has reached epidemic in Western world. The urgency in finding the solution has become the first priority in some research communities. Many researchers suggested that increased consumption of nonoilseed pulses of dry beans, peas, chickpeas, and lentils may be helpful in weight control, as they are slowly digestible carbohydrates, with high fiber and protein contents, and moderate energy density. In a randomized controlled trials generally support a beneficial effect of pulses on weight loss when pulse consumption is coupled with energy restriction, but not without energy restriction, found a beneficial effect of pulses on short-term satiety and weight loss during intentional energy restriction. Other study into the growth, hormonal status and protein turnover in rats fed on a diet containing peas (Pisum sativum L.), showed a positive effects as lower levels of plasma insulin, corticosterone, IGF-I and T4 is observed as compared with casein controls. Liver and muscle total protein (mg) and total DNA (mg) were markedly decreased in the legume fed animals.

The Side effects
1. Purines
Excessive intake of purine can cause health problems for people with untreated kidney and gallbladder diseases due to accumulation of uric acid.
2. Etc.
