A great word of advice when eating healthy is to read the labels on the back of the products that you are buying. A lot of foods contain things in the first five ingredients that you should avoid if you want to diet such as sugars, fat or lard, partially hydrogenated oil, high fructose corn syrup, and enriched flours. Granted alot of products in the grocery store contain these, even most breads.
Ive found the best way to eat right is to make your own bread sometimes so you know what you are putting in. A bread machine can be a great investment. I love making bread because there are so many different kinds that I can make that are healthy for you.
