A good diet with fresh fruits and vegetables, whole grains, protein from meat and fish, natural anti oxidants like red wine and garlic and healthy oils like olive and canola oil is what makes sense to me. Sure a nice steak or fast food burger is OK once in a while. Limit your intake of processed foods and sugars (in my opinion high fructose corn syrup is nasty stuff and should be avoided), drink lots of water, limit your intake of salt, but a salt free diet is not necessary and get some exercise. Check with your doctor about your weight, to treat any other problems like high blood pressure and screen you for common cancers.
Heredity is a big factor in my opinion. My father ate lots of red meat, didn't exercise and smoked cigars yet lived to be 96 without any heart or cancer issues. Ditto for my mother's 99 year old sister.
Good points. . I use to use canola oil, too until I found out the bad news about it. Also, I also researched the olive oils and not all are alike. You might take a look at the information regarding the various oils.
I was a primary care giver for years and my health took a nose dive. . .decided I needed to pray about it, revisited my diet and nutritional intake (did not go to the doctors) and everyone I know remarks that I look better.
