Read the fine print. When you are grocery shopping, don't be fooled by packaging that gives the impression of containing healthy food. Don't assume that because it is "low-fat" or "organic", that it is healthy. Take a second to flip the box over and read the nutrition information panel and ingredient list to determine its nutritional content for yourself.
Hard boiled eggs are a healthy and easily portable protein source. Boil a bunch and keep them in your fridge to take with you when on the go, or packing a lunch. They are economical and will help you feel great. Protein keeps us feeling full and energetic.
If you're looking to improve your nutritive intake, but aren't yet ready to make huge changes, start with small ones. For example, if you like white bread, it's completely painless to switch to one of the "soft wheat" breads currently available. Some brands are as white as their low-fiber white-bread cousins, yet they provide much more fiber per slice.
