Cooking advice
Try Eating Raw Food : Your body needs time to adjust and clean itself. Start including more fresh fruit, green salad, and green juice in your meals. Cut back on meat, dairy products, and cooked starchy foods. Try eating all raw one day per week, then two days. Or eat only two cooked foods per meal, then only one. You'll feel the difference.
Track down specials and buy in bulk. Buying in bulk means less trips, and can be a good way of reducing your food miles.
Buy Local Food : ...but at the same time, figure out what makes sense. It is more energy efficient to raise lambs in New Zealand and ship them to the UK than to raise them in the UK, because New Zealand lamb farming is more energy efficient. It is also more energy efficient to buy produce raised in Spain, than produce that has to be grown in greenhouses in the UK. Baby steps require figuring out which things make sense and which don't.
Kitchen safety
Always clean the grill pan after using it.
Never leave your cooking unattended. Even if the phone or doorbell rings. Remember - fires start when your attention stops.
