Why do vegetables get boiled?
During the cooking process, some nutrients leach out of the vegetables and into the cooking water. The longer they cook, the more nutrients escape. When making a soup or stew, this may not be an issue, as the broth is consumed along with the rest of the soup. However, when cooking vegetables intended as a side dish, a snack or a meal, boiling will result in vegetables that have some level of diminished nutrients. Overcooking also dulls color and flavor.
How to retain nutrients in microwave?
The primary factors in retaining nutrients when using a microwave are short cooking times and little added water. Use as LITTLE water as possible when microwaving — that’s where the nutrients are loss.
Why is microwave cooking better than other methods?
However, because microwaves cook foods quicker, they may actually do a better job of preserving nutritional content that can be destroyed as a result of high heat exposure. Nutrients are also better preserved when minimal amounts of water are used during cooking.
Why do you steam vegetables?
The goal of steaming is to cook the vegetables until they are no longer raw, but still bright and crisp. This preserves color and flavor, and some of the nutrient content.
Does microwave cooking help with nutrients?
According to Harvard Health Publications, certain nutrients, such as vitamin C, will break down when exposed to heat, regardless of whether you cook using a microwave or through more conventional methods.#N#However, because microwaves cook foods quicker, they may actually do a better job of preserving nutritional content that can be destroyed as a result of high heat exposure. Nutrients are also better preserved when minimal amounts of water are used during cooking. To further preserve the nutritional content of vegetables, Columbia University recommends not peeling the vegetables and using large pieces. Cover the foods so they steam during the cooking process, further reducing the cooking time.
Which has more beta-carotene, canned or frozen?

How to preserve nutrient in food?
While most forms of fruits and vegetables will provide a variety of nutrients, the Oregon State University Extension program recommends some strategies for maximum nutrient preservation. Refrigerate raw vegetables and use them as soon as possible. Buy local produce to prevent nutrient loss in shipping, and cook raw vegetables in a small amount of water. Canned foods should be stored in a cool dark place, and the brine or syrup should also be consumed. Frozen foods should be kept from temperature fluctuations and packaged properly.
Why is cooking important?
Cooking has been used for thousands of years to help soften food such as whole grains and dried legumes, to decrease the risk of parasites in meat and to help people digest food more easily. But research of cooking process has produced some interesting facts. For example, lycopene is an antioxidant found in watermelon, red bell peppers and tomatoes.

Why does vitamin C leach out of vegetables?
Because vitamin C is water-soluble and sensitive to heat, it can leach out of vegetables when they’re immersed in hot water.
What are the factors that affect the loss of nutrients in vegetables?
According to a recent ‘Ask Umbra’ column on Grist, there are three factors affecting nutrient loss when you cook vegetables: temperature, time, and water . “Nutrients tend to be both heat-intolerant and water-soluble,” the article says, which means that any method that requires a) cooking at a high temperature for a long time, and b) uses a lot of water will result in the greatest nutrient loss. (So by this measure, boiling vegetables is likely the worst offender.) It goes without saying then that cooking at a lower temperature for a shorter amount of time and with less water would result in the least amount of nutrients lost, and that’s what the microwave accomplishes.

Does microwave cooking deplete nutrients?
Have you ever been told that microwaving vegetables depletes their nutritional value? Anytime you cook a vegetable (regardless of the method) there is usually some nutrient loss, but the belief held by some is that microwaves destroy up to 90 percent of the nutrients in the food, whereas stovetop cooking can be as low as 10 percent. But is it true? Here’s what we discovered:
