I m 32, almost 300 pounds. I used to eat a lot of salt, sugar, fast food ect. I do a lot better now than I used to, but I still need to improve a lot. Lately, I sometimes have pains in my left arm. It isn t severe pain, just irritating more than anything but it does happen about everyday. I was just wondering if I could have a heart attack or heart disease at this early in age or is there time to change? And I have made a lot of small changes such as there are a lot of bad foods I used to eat that I don t eat anymore. Does making even small changes improve my heart health?
