Cooking vegetables won't "deprive" them of vitamins since they will still have the vitamins after cooking. However, cooking will alter the vitamins' structures (heat denatures things like enzymes and proteins), which can then lower the bioavailability (the availability a nutrient has to be absorbed by the body) of the vitamins once you eat the cooked vegetable. The vitamins and nutrients are still present, but not to the extent they were when the vegetable was raw. To get maximum nutrients and vitamins from vegetables, eating raw or fresh-frozen (vegetables that are frozen at the peak of freshness - all the good stuff is still present) are the best. However, there are some important nutrients that become more bioavailable to the body after the cooking process (such as the antioxidant lycopene found in tomatoes).
Cooking destroys vitamins because the heat from the cooking ruptures the cells of the vitamins and therefore renders the nutrient useless to the body. However, cooking makes certain foods higher in vitamins, but you need to know from the list which ones they would be.
Cooking tends to destroy vitamins through the heat. However, some foods increase in vitamins through cooking.
Vitamin C is easily destroyed during preparation, cooking or storage so follow these easy tips to retain as much of the vitamin as possible. * Eat raw fruits and vegetables as soon as possible after buying them. * Cut vegetables just before eating or cooking. * Cook vitamin C-rich foods quickly in as little water as possible. * Microwave, steam or stir-fry to retain the most Vitamin C.
Most of the fruit juices contain many vitamins like A C E . but the storage of juices for a long time can destroy the vitamins.
Obviously, losses of vitamins depend on cooking time, temperature, and cooking method. Some vitamins are quite heat-stable, whereas others are heat-labile. From textbooks in nutrition, such as Kreutler et al. [1987], many other factors than heat can destroy (some) vitamins, such as: solubility in water, exposure to air (oxidation), exposure to light (UVs), heat, acid and alkaline solutions, storage losses, etc.
In some cases the vitamin can be destroyed during the cooking process. This is one of the main reasons many nutritionists are turning to the "raw food" type diets.
It destroys some but not all; you can minimise the quantity that are destroyed by steaming or blanching the veg, and eating them on the crunchy side.

Consumers are able to purchase synthetic or all natural vitamins for consumption, but few people understand the difference between the two forms. Many of the vitamins in grocery and drug stores are synthetic vitamins, which are made through a chemical process. All natural vitamins are supplements that are derived directly from natural sources without the use of a chemical process. All natural vitamins do not contain sugar, artificial chemicals or the use of extreme heat or pressure during processing. Many health professionals believe that all natural vitamins are more beneficial than synthetic vitamins because they are more pure and of a higher quality.
By how many pigs you get as well as how many of the other stones, sticks and other items you destroy in the process.
no, many of the vitamins are destroyed in the freezing process. fresh is always best

If you salt a steak before the cooking process it becomes dry because the sodium in salt naturally absorbs moisture.
