Decide to take pride in yourself and your nutrition, and enjoy eating right. It is more expensive to buy healthy, natural food, but by doing so you might eat less.
Yes, processed and refined foods are inexpensive and convenient, but they come with a higher price than you think. I encourage you to move the grocery bill up on your financial priority list. Optimal nutrition is essential for healthy function with age, and you can?t put a price tag on that.
