After having my first heart attack at 23. . . My partner and I are very strict on our diet. We eat zero fried foods, and surprisingly we have found that every park we visit has something healthy we can eat. It just takes some time and some research. . . Some people consider it a "free day," But we don't. To us it just a normal "eating healthy" kind of day.
Also, never drink soda. Always water. Only water. Always.
