Daisy Williams admits genes play some role in the way she looks,but believes diet is an important factor."It doesn't matter how good the genes are if you don't eat properly and take care of your-self,"she says."If you want to look good,get plenty of rest,exercise every day,eat mostly raw fruits and vegetables and quit worrying."
Nowhere do the signs of aging manifest themselves more clearly than in the condition of the skin. When your weight fluctuates(波动),the skin stretches with each up cycle , but it may not completely shrink back to its original size in the down cycle. As a result,the skin may sag(松弛下垂).
Zinc and vitamin A are important for normal,healthy skin.Zinc helps the skin repair itself, and vitamin A aids in keeping skin supple,preventing dryness and helping shed dead cells.Good sources of zinc are beef,eggs and seafood,while many dark-green leafy vegetables are rich in beta carotene(胡萝卜素), which the body converts to vitamin A.
Vitamin C helps improve the blood supply to the skin and aids in forming collagen(胶原). Good sources of vitamin C include citrus fruits and juices,cauliflower,snow peas,red and green peppers,broccoli,white and sweet potatoes, tomatoes,watermelon,and honeydew melon.
How food is prepared matters too.The longer vegetables cook,the greater the loss of vitamins. Don't soak vegetables when washing them,since water-soluble vitamins such as C will be lost.
Good general nutrition is essential to maintaining a healthy,youthful appearance.And the key to good general nutrition is balance.Proteins should make up roughly 10 percent of your daily calorie intake;no more than 30 percent should come from fats;and the remaining calories should come mostly from complex carbohydrates(碳水化合物).
