Lunch plays a connecting role in a day's life, because the collocation of nutrition can not be ignored. Seafood or chicken is rich in low fat and high protein, while vegetable salad is rich in calories and nutrients, providing you with oxidants to ensure the normal contents of vitamin C and vitamin E in your body. This can reduce the incidence of cardiovascular diseases, obesity and hypertension. Olive oil is known as the "queen of vegetable oil", which can reduce blood fat and cholesterol, prevent various cancers and have cosmetic effects. Carbohydrates in rice can provide you with enough energy.
