Yoga and my spiritual development makes me change gradually what I eat. The two things I focus on at present is to eliminate or at least cut down on sugar and dairy. When it comes to sweets I do not like the concept of artificial sweeteners, I avoid them completely.
Zen Habits has a great post about sugar: Beat the Sugar Habit: 3 Steps to Cut Sweets (Mostly) Out of Your Life. There is a list of the bad things with sugar as well as a list of tips on how to beat the sugar habit.
Epic Self raised an interesting question in “Dare We Eat Dairy?”:
When it comes to nutrition, the milk debate is probably as confusing and controversial as it gets. Is cow’s milk a cancer fighting, PMS subduing, osteoporosis preventing super food? Or is it just another multi-billion dollar industry working with the government to alter dietary guidelines in their favor?
It also says:
Today we tend to look to scientific evidence to tell us what and how much to eat. But, what happened to paying attention to how you personally feel after eating certain products? Tuning into the internal workings of your own body will give you some clues into how to moderate or in some cases eliminate dairy from your diet.
My own experience is that dropping sugar and dairy makes me feel better.
