Hello @danlewis, Welcome to Connect. Thank you for starting such a great discussion for us seniors. A few years ago I started changing my eating habits to eat healthier, lose some weight and hopefully help with a couple of my autoimmune conditions. The National Council on Aging put out this information earlier this year that is a good start.

I think part of your question of what not to eat may depend on certain health conditions if you have them. I try to stay away from all fast foods and limit my snacking as well as most processed foods. I think @avmcbellar and other members may also have some suggestions to share with you. @hopeful33250 started another discussion on breakfast that you might want to join also - Start Your Day Right: https://connect.mayoclinic.org/discussion/start-your-day-right-1/

Do you mind sharing what prompted you to start looking for what to eat or not eat for better health?
