Nutrition for Breast Cancer Prevention

Related Conditions
Breast Cancer

Changing your relationship to food and eating involves a major shift in thinking, feeling and doing. The goal of this shift is to create a lifestyle change, not to temporarily lose weight on a diet.

Choosing, making and eating food with an "Abundance Model" includes the pleasures of delicious choices, many tastes, ample portions, not feeling limited, not counting calories and eating when hungry.

This is in contrast to the more common "Deprivation Model" where rules of "do not" and "should not" leave us feeling bad or guilty with unmet hunger and cravings. Cycles of stress and depression-related eating are common with this model. A shift from "I can't eat without feeling bad and guilty" to "I enjoy an abundance of healthy, delicious food" often results in a better-nourished and healthier self.
