I would prefer paleo, but Campbell looks great for an 80 year old man. Personally, I would rather die younger than go vegetarian.
I’ve done both ways of eating... Was on a fat-free vegan diet for a long time. Health benefits I saw right away... my vision improved, no longer needed the reading glasses I just purchased.
However... in November I started eating a Paleo diet... full swing to the other side. Still eat tons of veggies.. but eat grass fed meat as well, and limited dairy ie grass fed heavy cream and butter. Lost the extra weight I couldnt’ shake from practicing a fat-free vegan diet.. and feel great. No sugar ups and downs at all...
Not sure which is better... it’s probably an individual metabolic issue. Either diet will want you to stay away from processed foods and sugars... which is the stuff that kills you earlier than later.
He’s not advocating a vegetarian diet. It is a Whole food plant based diet. Do you want to live to eat or live to eat? Just how sick do you want to be when you are 60 years old? Keep eating the typical American Diet and you will lucky to escape chronic illness after 55.
