You asked: What nutrients are lost during cooking?

Which nutrients are lost when cooking vegetables?

Water-soluble vitamins leach into cooking water, so vegetables lose greater quantities of vitamin C, thiamin, riboflavin, vitamins B-6 and B-12, niacin and folate. Some minerals are lost in water, but they survive better than vitamins.

What vitamins are easily lost during cooking?

Vitamin C is a water-soluble and temperature-sensitive vitamin, so is easily degraded during cooking, and elevated temperatures and long cooking times have been found to cause particularly severe losses of vitamin C [12].

What nutrients are lost during stir frying?

Stir-frying and stir-frying/boiling, the two most popular methods for most homemade dishes in China, cause great losses of chlorophyll, soluble protein, soluble sugar, vitamin C, and glucosinolates, but the steaming method appears the best in retention of the nutrients in cooking broccoli.

What percent of nutrients are lost in cooking?

It’s difficult to say exactly, but the differences among various cooking methods isn’t as great as you might think. For minerals like iron, calcium, magnesium, potassium, and sodium, the loss is only in the range of 5 to 10 percent no matter how the vegetable is cooked.

How can we avoid destroying nutrients when cooking?

The three R’s for nutrient preservation are to reduce the amount of water used in cooking, reduce the cooking time and reduce the surface area of the food that is exposed. Waterless cooking, pressure cooking, steaming, stir-frying and microwaving are least destructive of nutrients.

Does cooking time affect nutrient loss?

Heat diminishes vitamins and phytonutrients (beneficial plant compounds other than vitamins or minerals) in fruits and vegetables. The longer they cook, and the higher the temperature, the greater the nutrient destruction. Even chopping food can begin to erode some of the nutrients.

What is the best way to cook vegetables to keep the nutrients?

While methods like steaming are better than boiling, the answer depends on the vegetable. As a general rule, keep cooking time, temperature and the amount of liquid to a minimum when cooking vegetables. That’s why steaming is one of the best ways to maximize nutrients.
