Health care professionals would much rather prevent health problems than have to cure them. That being the case, you'll find that most clinics, doctor's and dentist's offices, and health related web sites offer a vast array of free literature on just about every health care service. Don't be shy -- take advantage of it!
A good diet is an excellent and inexpensive form of health care, since everything from heartburn to obesity, heart disease to diabetes can be either helped or prevented by eating a proper diet. If you're uncertain which diet trail to go down, talk to your doctor for ideas.
