Is it true cooking in a pressure cooker preserves vitamins and nutrients?

Scientists from Norway have proved that cooking with pressure slows the molecules that normally speed up during normal cooking. Since this slowing occurs it doesn't knock around the nutrients as much as normal cooking does and therefore locks in the nutrients and the freshness. It has also been shown that Palaeolithic Man sat on his food while cooking for this very reason. Though it is believed he would have "burned his biscuits", scientists believe contributed directly to our evolution.

Why is salt added to cook pulses at atmospheric pressure?
why salt is added before cooking pulse at atmospheric pressure
How food is cooked easily in pressure cooker?
During heating the pressure increase in the pressure cooker; as a consequence the temperature increase, the cooking is faster, part of energy saved, etc.
How do the Boyle's law is applied in a pressure cooker?
As temperature increases, so does the pressure.
How do you make fish bones soft?
pressure cooking them helps alot. Like how canned sardinees are made.
Why the boiling point of water in pressure cooker high?
A pressure cooker minimizes the escape of fluids or air. The build-up of air and fluid increases the pressure inside the cooker, which also increases the boiling point. An open kettle allows the fluid and air to escape, heat is lost thus cooking time is longer.
Should you use slow or pressure cooking to keep vitamins?
The faster you cook something, the less the nutrients are damaged.
What are the advantages of a pressure cooker?
The increased Pressure inside of a closed vessel will allow the cooking temperatures in the Foods' Moisture to go above 212o (boiling point of water). Therefore the higher temperature reduces the Cooking Time, and preserves Nutrients. Some people also feel that it helps to preserve Flavor.
Does the cooking process destroy many vitamins?
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).
What are the effects of over cooking?
If food is overcooked,then it loses all its nutrients,vitamins&minerals.
Will cooking food in water delute the vitamins in them?
Yes excessive cooking does destroy the vitamins.
Does cooking effect on vitamin c content of citrus fruit?
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.

How do nutrients get lost during the process of cooking and preparation show can you prevent then?
Some minerals and vitamin A are also lost during cooking, although to a lesser extent. Fat-soluble vitamins D, E and K are mostly unaffected by cooking. Boiling results in the greatest loss of nutrients, while other cooking methods more effectively preserve the nutrient content of food.Steaming and boiling caused a 22 percent to 34 percent loss of vitamin C. Microwaved and pressure-cooked vegetables retained 90 percent of their vitamin C. The bottom line is that no one cooking or preparation method is superior for preserving 100 percent of the nutrients in a vegetable.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
What is the key advantage of high pressure steaming?
High pressure steaming allows you to cook your food, but saved most of the nutrients in it. Such as steaming broccoli instead of cooking it in water.
What is conservative cooking?
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.
Does cooking of yam makes the nutrients get dissolved in the cooking water?
Yes, cooking of each and every food item makes it loose some nutrients.
Do Cabbage nutrients get lost if fried or cooked?
Cooking anything will make it lose some nutrients by denaturing proteins (good for browning) and breaking down vitamins and minerals. Boiling things, especially, can take away nutritional value into the water fairly quickly.
