General tips
Oven Tips : Use glass or ceramic pans in ovens. You can turn down the temperature about 25° and foods will cook just as quickly.
Buy Seasonal Food : Most food, from fruit to fish, has a season -a time when it is abundant and at its best. Knowledge about food's seasons was once essential to survival and became culturally ingrained over the centuries. Today, we have all but lost this accumulated wisdom, but it still matters! Buy local and seasonal to guarantee the best quality food you can get.
Losing weight
The Glycaemic Index Diet
The gi (or glycaemic index) weight loss program is reliant on the glycaemic index, a chart showing food types and a score representing the speed that the glucose in the food type gets changed to glucose in your system. The claim is that long-acting food types (ie those foods with a low Gi number), keep you satiated for longer and help to injest less food without feeling hungry.
It's also very useful for diabetics, as the low GI foods are beneficial in controlling surges in glucose levels.
