I think most people would agree that eating healthy is hard. For me, I don't have trouble eating healthy foods, I just have trouble figuring out what a healthy food is. I mean, who do you trust to tell you what healthy food is? your doctor? where does your doctor get his information on healthy food from?
I watched a documentary that changed how I thought about nutrition. I could no longer look at something and be sure if it was good or bad for me because I lost faith in the diet that politicians(I don't trust politicians, yet I trusted them with my health??) put forth as healthy. Which is the diet I learned in health class, most likely the diet your doctor learned as well.
I think everyone should examine what they think of as healthy, and find a diet researcher they feel is authentic and follow there advice.
I say researcher because it needs to be someone who has dug through the raw study data and come up with there own ideas on nutrition, not just someone who read "blabla is bad, blabla is good" and took it on faith because then you are just trusting whoever they just trusted...
