This will vary based upon the vegetable and cooking method.
Generally, steaming vegetables is thought to retain the most nutrients.
----
To keep nutrional value of vegetable, and even potatoes, steam your food rather than boiling, but do not over cook.
Vegetables can maintain their nutritional value through steaming. This is the most efficient way to help the vegetable retain their minerals and vitamins.
Vitamin C or ascorbic acid is destroyed when we cook vegetables.
No if you microwave the vegetables the nutrients cook right out. The best bet is boiling your vegetables but not to long so all the nutrients don't cook out!
Yes. Heat can destroy nutrients in all vegetables. The only vegetable, also known as a fruit, that does not loose nutrients is tomatoes. The longer the vegetables are cooked, the more nutrients are lost. The nutrients are lost through the water its steamed in, and the steam itself. Raw is best, but if you must cook them, cook until slightly tender, where some nutrients are still there.
a conservative method is one that conserves the nutrients that are easily lost upon cookingand to ensure that they are available for the body to utilize.
Cooking vegetables makes nutrients more available for the body to absorb, but overcooking can mean losing nutrients. Plant cell walls are broken down in cooking, which means the food can be more completely digested and used by the body. While potato should be well cooked, overcooking less starchy vegetables will result in loss of nutrients, so steaming or microwaving vegetables (so they are still crunchy) helps retain most nutrition. Meat should always be well cooked to destroy bacteria and make nutrients available for the body to absorb
You can cook leafy vegetables by steaming, boil and grilling them.
For some veggies there isn't really a need to cook them it just makes them taste better.
cook turkey and vegetables
As long as you cook the meat thoroughly (because it may take longer to cook than the veggies, depending on thickness), it should be safe.
Fresh fruits and vegetables; don't cook them until they get dark, dry or mushy, that eliminates the nutrients in them. NO SOFT DRINKS, drink water instead.
The faster you cook something, the less the nutrients are damaged.
Vegetables and fruits have the most nutrients when they're harvested, and they begin to lose them as soon as they are harvested. There are other things we can do to fruits and vegetables to hasten this destruction of nutrients after harvest, including:Storage: The longer vegetables and fruits are stored before using, the more nutrients are lost.Cutting: When a plant is cut, it goes on the defensive and activates enzymes that destroys its own nutrients, causing brown discoloration.Cooking: Over-cooking diminishes nutrients by breaking down the cells. When food is fried, barbecued, or baked at high temperatures, toxic compounds such as acrylamides are formed and most important nutrients are lost. Many vitamins are water-soluble, and a significant percent can be lost with cooking, especially overcooking. Boiling makes it easy for nutrients to leach into the water. Many plant enzymes function as phytochemical nutrients in your body and they, too, can be destroyed by overcooking.Freezing. Frozen food is pre-cooked to inactivate the enzymes so that the food won't turn brown, making it easier to over-cook, and diminishing the Vitamin C in particular.Blending or juicing. Juicing breaks down fruits and vegetables into such tiny parts that the nutrient loss begins rapidly. Very few nutrients will be left in the juice or smoothie after 24 hours.To minimize destruction:Buy the most recently harvested fruits and vegetables you can. Think locally grown produce from farmers markets.Buy whole fruits and vegetables instead of pre-cut and bagged.Enjoy as many as possible whole and raw.If you do store them, don't peel or pre-cut.If you do cook them, cook them whole or cut them into large pieces right before you cook them, and cut them into extra large sizes to cook and cut smaller after cooking.Avoid peeling most fruits and vegetables, as many nutrients are in or just under the skin. If you must peel cooked vegetables, peel them after cooking, as the skin helps keep nutrients in during cooking.Avoid boiling and discarding the water. Use steam so the nutrients won't leach into the water. When food is steamed or made into a soup, the temperature is fixed at 100 degrees Celsius (212 degrees Fahrenheit), the temperature of boiling water. This moisture-based cooking prevents food from browning and forming toxic compounds. Most essential nutrients in vegetables are made more absorbable after being cooked in a soup and water-soluble nutrients are not lost because we eat the liquid portion of the soup too. Only small amounts of nutrients are lost with making a soup, but many more nutrients are made more absorbable. When you heat, soften, and moisturize vegetables and beans, you increase the digestibility and absorption of many nutrients, including protein.Use frozen fruits and vegetables only when fresh are not practical.Drink freshly made smoothies and juice immediately after you make them. Avoid buying bottled juice, which aside from being stored, has also been pasteurized.
