The American Heart Association does not have a specific in-depth diet plan, as of 2015. Rather, the charity provides a list of recommendations and guidelines for maintaining a healthier diet and lifestyle. These are located in the Getting Healthy tab on Heart.org.
The American Heart Association website has a number of dietary recommendation pages that deal with general health as well as problems directly associated with diet and lifestyle. These problems include obesity, stress and smoking. The charity makes suggestions such as monitoring calorie intake, expanding food variety to include more nutritious foods, and improving eating patterns.
Instead of offering an ineffective, short-term diet plan, the American Heart Association provides the guidelines to create a more healthy and happy lifestyle overall.
