I don’t worry about eating “enough” but I eat them as much/when I want. I enjoy a nice big salad or a nice veggie stir-fry, lots of fat incorporated in some manner and eggs/meat in large portions.
Dr. Rhonda Patrick does a lot of work on how some veggies may have anti-aging properties and how they might turn some genes on, some genes off, and impact telomeres. Since I enjoy eating the veggies she discusses (broccoli/kale/avocado/etc) I eat them almost daily and hopefully kill two birds with one stone, getting nutrition in a manner/level that MAY extend my life and enjoying the flavors/textures etc.
I don’t think I’d force myself to eat any veggie if I didn’t like the flavor/texture etc. BUT, I have found that as I’ve aged, I enjoy them more and that I enjoy them even MORE when lightly sauteed in bacon grease etc.
