What vegetables lose nutrients when cooked?

Vegetables are generally a great source of vitamin C, but a large amount of it is lost when they’re cooked in water. In fact, boiling reduces vitamin C content more than any other cooking method. Broccoli, spinach, and lettuce may lose up to 50% or more of their vitamin C when boiled ( 4 , 5).

Do vegetables really lose nutrients when cooked?

The fact is that all forms of cooking can destroy some of the nutrients (such as vitamin C and B vitamins) in vegetables. But the flip side is that some nutrients actually become more bioavailable when vegetables are cooked, since cooking helps release the nutrients from the cell walls of the plant.

How do you cook vegetables without losing nutrients?

To retain these vitamins, cook vegetables in as little water as possible for a minimal amount of time (unless you’re planning to consume the water, as in a soup). Steaming and microwaving, both of which use little water, will give you the same results as boiling or blanching but with much less nutrient loss.

Does cooking broccoli destroy nutrients?

Most of the minerals in broccoli are retained during cooking because they stand up to heat and water better than vitamins. If you steam, stir-fry or roast your broccoli, you’ll get 100 percent of its minerals, according to the USDA. When broccoli is boiled, it loses 5 percent to 10 percent of the total minerals.

Which vitamin is not destroyed by cooking?

This is because some, such as vitamin C and the B vitamins, are water soluble, meaning they leach out when in water. And some, such as vitamins A and E, are fat soluble, so that if you deep-fry them or stir-fry in oil they will leach out into the oil. Vitamin D is stable and unaffected by heat.
