What are the best methods for retaining the water soluble vitamins when preparing food?

Steaming. Steaming is one of the best cooking methods for preserving nutrients, including water-soluble vitamins, which are sensitive to heat and water ( 4 , 5, 6, 17 ). Researchers have found that steaming broccoli, spinach, and lettuce reduces their vitamin C content by only 9–15% (5).

Does steaming remove nutrients?

Water is the enemy when it comes to nutrient losses during cooking. That’s why steaming is one of the best methods to preserve easily damaged nutrients, such as vitamin C and many B vitamins. Since vegetables don’t come in contact with cooking water during steaming, more vitamins are retained.

Why can taking megadoses of individual mineral supplements be potentially harmful?

Taking megadoses of individual mineral supplements can greatly diminish the absorption and metabolism of other minerals. Taking megadoses of individual mineral supplements can increase blood pressure, increasing risk for cardiovascular disease and stroke.

How does baking affect nutrients?

Vitamin loss is inevitable when baking.

So it reduces the loss of nutrients. Still, if you add water in the baking dish, the food will be prepared through a combination of boiling and baking. So more nutrients loss. This cooking method destroys and inactivates some of the microorganisms in foods.

Which cooking method increases vitamin loss?

Steaming and microwaving retained higher concentrations of vitamin C than boiling because of the reduced contact with water at relatively low temperatures. Using minimal cooking water and cooking for shorter time periods should result in higher vitamin C retention.

How do vegetables preserve nutrients?

If you cook vegetables gently — and without a great deal of water — you will help protect the water-soluble vitamins. Filardo recommends blanching your veggies, which is when you quickly cook vegetables in boiling water, and remove them when they’re still very crisp, to help preserve the color and nutrients.

What are the effects of preparation methods on vitamins and minerals?

Processing (including preparation) makes food healthier, safer, tastier and more shelf-stable. While the benefits are numerous, processing can also be detrimental, affecting the nutritional quality of foods. Blanching, for example, results in leaching losses of vitamins and minerals.

What method of cooking is mostly used to cook vegetables?

How do water soluble vitamins work?

Water-soluble vitamins are those that are dissolved in water and readily absorbed into tissues for immediate use. Because they are not stored in the body, they need to be replenished regularly in our diet. Any excess of water-soluble vitamins is quickly excreted in urine and will rarely accumulate to toxic levels.

Where are water-soluble vitamins absorbed quizlet?

How do antioxidants protect the body quizlet?

How do antioxidants effect free radicals in the body? The vitamins C and E, are thought to protect the body against the destructive effects of free radicals. Antioxidants neutralize free radicals by donating one of their own electrons, ending the electron-“stealing” reaction.

What is an antioxidant quizlet?

What are Antioxidants? A compound that has the ability to prevent or repair the damage caused by oxidation. Antioxidants work by stabilizing Free Radicals or opposing oxidation.

Why do water soluble vitamins need to be consumed more often than fat soluble vitamins quizlet?

How do antioxidants protect cells?

Antioxidants neutralize free radicals by giving up some of their own electrons. In making this sacrifice, they act as a natural “off” switch for the free radicals. This helps break a chain reaction that can affect other molecules in the cell and other cells in the body.
