Broccoli, spinach, and lettuce may lose up to 50% or more of their vitamin C when boiled ( 4 , 5). Because vitamin C is water-soluble and sensitive to heat, it can leach out of vegetables when they’re immersed in hot water. B vitamins are similarly heat sensitive.
How do you cook vegetables without losing nutrients?
When in doubt, microwave. That’s because microwaving uses little to no water, and can heat the vegetable quickly, thus preserving nutrients such as vitamin C that break down when heated. Sauteing in a bit of healthy cooking oil, such as extra-virgin olive oil, is a great way to cook many vegetables.
Do cooked vegetables lose nutrient?
What happens is that when you cook vegetables, this affects the amounts and the availability of those nutrients in the vegetables.” She explained that water-soluble nutrients , like vitamin C, B vitamins or folate, can leach out of veggies when cooked in water.

Vitamin C
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].
Do vegetables lose their nutrients after being warmed up?
According to a review by researchers at the University of California, Davis, as much as 55 per cent of the vitamin C in vegetables is lost during home cooking (compared with raw). Vitamin C is also easily degraded by heat.
Are carrots healthier raw or cooked?
Carrots provide more antioxidants when boiled or steamed than when eaten raw, according to a January 2008 report in the Journal of Agricultural and Food Chemistry. In fact, researchers found that boiling carrots until tender increased the concentration of carotenoids by 14 percent.
Does broccoli lose nutrients when cooked?
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.
Is broccoli healthier raw or cooked?
raw
Besides, cooked vegetables retain some of their vitamin C content. That said, research shows that some veggies, including broccoli, are healthier raw rather than cooked.
Is cabbage healthier raw or cooked?
Although you get different nutrients if you cook or ferment it, raw red cabbage in particular might give you the best nutritional boost per serving. Slice it very thinly and leave it for about 10 minutes to help bring out the fullest, most complex flavors. Then add it to salads or sandwiches or turn it into coleslaw.
How do you prevent nutrient loss in cooking?
Take advantage of as many vitamins as possible by following these tips:
- Keep skins on when possible.
- Avoid continuous reheating of food.
- Use a minimal amount of cooking liquid.
- Choose steaming over boiling.
- When you do boil, retain the cooking liquid for a future use (like soups and stocks)
- Use the microwave.
Which vitamin is not destroyed by cooking?
The other vitamins such as vitamin-A, vitamin-D, vitamin-E, and vitamin-K are all fat soluble vitamins. They do not get destroyed when heated or exposed to air.
Does boiling carrots remove nutrients?
The vitamins in carrots that are fat-soluble, including vitamins A, E and K, are heat stable and won’t be destroyed by boiling. In fact, cooking can help break down the vegetable’s cell walls, freeing up more of the nutrients. Heating may also increase their calcium levels in carrots.
How do you cook broccoli without losing nutrients?
Steamed broccoli may be one of the healthiest ways to cook broccoli because it’s quick and nutrients and vitamins won’t be lost in the cooking water, as can be the case with boiled broccoli.
How do you keep nutrients in vegetables when cooking?
To preserve water-soluble vitamins, steaming is a better option than boiling vegetables. When steaming, keep the pot covered to reduce cooking time and avoid overcooking. Other healthy quick cooking techniques include stir-frying, pressure cooking, and microwaving. Roasting is a quicker technique than baking.
Does broccoli lose nutrients when reheated?
The greatest loss of vitamin C was observed in broccoli after stir-frying/boiling and boiling (38% and 33%, respectively) treatments, followed by microwaving and stir-frying (16% and 24%, respectively) treatments. In contrast, steaming did not cause any significant loss of vitamin C, compared with the raw sample (Fig.
At what temperature do vegetables lose their nutritional value?
These vitamins are found primarily in fruits and veggies that you already eat raw, like apples, oranges, carrots, and bananas. When these water-soluble vitamins are heated beyond 115 degrees Fahrenheit, they begin to lose their nutrition.

Do tomatoes lose nutrients when cooked?
In one study, researchers at Cornell University heated tomatoes and found their vitamin C content decreased as cooking time increased. Tomatoes cooked for 2 minutes had 10% less vitamin C than an uncooked tomato, and those cooked for 30 minutes had 29% less vitamin C.
Which cooking method destroys 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 ).
Why you should not boil broccoli?
