We're often told to "eat a rainbow", so we believe that the more colors the food has, the better it is. In fact, some white vegetables can offer us lots of nutrients (营养物) that we seem to be missing very often. Here are some white vegetables.
Mushrooms
Mushrooms are low in calorie and fat-free, so they can help you control your weight. And they are a rich source of umami (鲜味)，the fifth basic taste after sweetness, saltiness, bitterness and sourness. They can help simple dishes come alive.
Garlic
Besides tasting great, garlic can help the hair grow and keep colds and flu away. It can also help improve your immune system.
Onions
Julia Child said," I can't imagine a world without onions, so I always put some onions when I cook for my customers. " Onions can help you enjoy your life with a lower risk of cancer and heart disease.
