Hi All,
We must eat vegetables more in our diet plan as they are great for health. Some benefits of vegetables are:
They are great to reduce weight,
They prevent from certain types of cancer,
They stabilize blood pressure,
They prevent from diabetes,
They are great antioxidant,
They are used to treat asthma, coughs, common colds and flu,
They strengthens the bones,
They helps in better sleep.

Vegetable nutrition has widely drawn the attention of fitness conscious as well as food scientists alike for their proven health benefits. Many vegetables are very low in calories, such as celery which is even as less than 10 cal per 100 g and here is the long list of vegetables whose calorie is less than 20 per 100 g: Bottle gourd, Bitter melon, Cabbage, Chinese cabbage, Bok choy, Eggplant, Endive, Spinach, Summer squash, Swiss chard, etc.  Scientific studies have shown that low calorie but nutrient rich foods help body stay fit and disease free.

And, also our body spends considerable amount of energy during digestion of foods which is known as BMR or Basal metabolism rate. So just imagine…..when you add more vegetable nutrition in the diet, in fact you set to lose more weight than you would gain…Right!..This is the concept behind the "negative calorie foods".
