In fact, boiling vegetables may reduce the content of water-soluble vitamins by as much as 50–60% ( 7 , 9, 11 ). Some minerals and vitamin A are also lost during cooking, although to a lesser extent.
What nutrients are lost when boiling 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.
Are boiled vegetables healthy?
Many people think raw vegetables are more nutritious than cooked, but that’s not the case. Cooking vegetables breaks down the plants’ cell walls, releasing more of the nutrients bound to those cell walls. Cooked vegetables supply more antioxidants, including beta-carotene, lutein and lycopene, than they do when raw.
Why you shouldn’t boil vegetables?
Exposing vegetables to heat for too long. Doing so destroys the majority of vegetables’ nutrients. Boiling them is also a no-go. This method causes water-soluble micronutrients like riboflavin, folate, and B and C vitamins to leach out into the water—which most people then pour straight down the drain.
Do you lose all nutrients when cooking vegetables?
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 boil 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 boiling destroy nutrients?
Boiling results in the greatest loss of nutrients, while other cooking methods more effectively preserve the nutrient content of food. Steaming, roasting and stir-frying are some of the best methods of cooking vegetables when it comes to retaining nutrients ( 12 , 13 , 14 , 15 ).
Does boiling remove nutrients?

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.
Are vegetables more nutritious cooked or raw?
Raw food is not any healthier than cooked food. Cooking decreases some nutrients, yet increases others. It also destroys certain harmful compounds and kills bacteria.
Does boiling vegetables in soup remove nutrients?
Boiling vegetables as an accompaniment to a main meal results in some of the nutritional value being lost in the water, which is usually thrown away. Making soup with vegetables means the nutrients stay in the liquid.
Is steaming or boiling vegetables healthier?
Boiling veggies leads to a lot of nutrient loss, and the longer the veggie boils, the more nutrients will escape into the water. Steaming veggies on the other hand is a brief process, and it is the method that leads to the least loss of nutrients in most veggies.
Does boiling potatoes remove nutrients?
MOST COOKING METHODS DESTROY THE NUTRIENTS IN POTATOES. While boiling potatoes does cause a small loss of water-soluble nutrients like vitamin C and vitamin B6, the white potato retains most, if not all, of its potassium and dietary fiber regardless of cooking method, such as baking, boiling, or frying.
Does cooking onions destroy nutrients?
