Have you always wondered how to prepare vegetables in order to maximize their nutritional content? There’s no easy answer, since some produce is most nutritious cooked, while other kinds do not need heat to bring out the best in them. Here is how to get the most from the farmers’ picks.
Onions
Just slice and eat them raw. You get less of the phytonutrient allicin, a hunger busting ingredient when you cook onions. On the other hand, they contain a flavonoid known as quercetin. It has anti inflammatory properties. Total amount of flavonoids can be increased by cooking. Yellow and red onions have more flavonoids than white ones. Sauté or bake onions for five minutes; any longer and the onion will begin to lose nutrients.
Broccoli
Eat it raw. Heating deactivates myrosinase, an enzyme that helps cleanse your liver of carcinogens. Broccoli or other cruciferous veggies, such as cabbage, cauliflower, kale and Brussels sprouts are good examples of vegetables which should be eaten both cooked and raw. Raw broccoli contains an enzyme called myrosinase which breaks down into sulforaphane, a compound helping to prevent cancer and stomach ulcers. Cooking damages myrosinase. On the other hand, cooking forms the compound indole in cruciferous veggies. It is a phytonutrient that fights precancerous cells before they turn malignant.
Beets
Eat them raw. Beets lose more than 30 percent of their foliate while cooking. Eating them raw will store this brain compound.
Mushrooms
Eat them cooked. Whether you heat, sauté, boil, roast or grill them, more muscle-building potassium will be brought out.
Red peppers
Eat them raw. Their vitamin C breaks down while roasting, frying, or grilling above 370 degrees. Red peppers are high in vitamin C that is nutrient soluble in water. By boiling or cooking red peppers, the vitamins dissolve in the water. It is best to eat red peppers raw.
Spinach
Eat it cooked. Have spinach cooked and you will absorb more iron, calcium and magnesium. Though raw spinach is still good, cooking makes it easier for your body to absorb the calcium it contains. Calcium is essential for teeth and bone strength, so make sure you get the most out of the spinach. Steam your spinach rather than boiling it to avoid losing nutrients.
Tomatoes
Eat them cooked. Are you surprised? When you eat cooked tomatoes, your body absorbs more cancer fighting lycopene. Tomatoes contain lycopene, an antioxidant linked to the prevention of cancer and other chronic diseases. Researchers have found that lycopene molecules change tomatoes’ shape, which makes them more usable by the body. The amount of lycopene in tomatoes is higher and it is better absorbed by the body after cooking with a little oil, and particularly processing, rather than eaten fresh or raw.
Carrots
Raw carrots supply polyphenols, chemicals with antioxidant properties thought to reduce the risk of cancer and heart disease. Boiling carrots destroys all the polyphenols as well as cooking, which breaks down the vitamin C found in carrots. This vitamin is easily degraded when exposed to heat. It is said that cooked carrots supply more of the antioxidant ß-carotene than raw ones. Your body converts this antioxidant to vitamin A.
Garlic
Cooking makes the herb garlic less potent because heat reduces the amount of healthy allicin, so it is best to add your garlic just before you finish cooking rather than at the start. Garlic contains chemicals that relax your blood vessels, helping to protect you from heart attack. Cooking garlic reduces the amount of these vital chemicals, so it is better to enjoy garlic raw.
