Health and conservation
How should you cook in a healthy and conserving way and yet still be able to enjoy the results of your efforts? Consider in the first place whether the food, in fact, needs to be cooked for lengthy periods of time. A healthy diet depends to a large degree on foods that are as near to their natural state as possible, thus retaining their vitamin content and nutritional value.
Vegetables should be absolutely fresh, preferably young, and they should be prepared with the minimum of wastage. Fresh raw vegetables and fruit are highly nutritious and retain most of the minerals, vitamins, trace elements, and fibre often destroyed by cooking. They are also good for the teeth and digestion. You can eat the overwhelming majority of vegetables raw, after thorough preparation, which includes washing them thoroughly to remove any trace of possible pesticide residues. You should peel some vegetables, including commercially grown carrots, for the same reason. Raw root vegetables, potatoes apart, are excellent grated and have better, more distinct flavours than when cooked. Leaf and stem vegetables should always be perfectly fresh whether you intend to eat them raw or cook them, since the vitamin and mineral contents decline rapidly once they are harvested. (more…)
