There can be little doubt that some foods are better than others.
But, only in a general way.
For a person with high blood pressure too much salt can shorten their lives. People with some forms of arthritis are better off avoiding meat. You can find a thousand and one examples of why someone should or should not eat
any single food item. However we simply vary too much to say any one thing is categorically bad for everyone.
I'm more than a little over weight (Go ahead say it - FATSO). But my cholesterol and blood pressure has always been low. Pulse is normally around 65.
I have some good eating habits, but others that might kill anyone else. I LOVE a bucket of fried chicken.
There have been diet/health conscious celebrities such as Adelle Davis, and others, dropping left and right over the decades from cancer and other causes for which a healthy diet was supposed to offer protection. Even marathon runners
have died from heat attacks.
If I had children in school, I'd rather that they eat healthy. But it is
I who would be the one pulling the pop-tarts out of their bags. I wouldn't force others into a particular diet regime because I thought it best for them.
After all, it didn't work for me, and I was already predisposed to snack on veggies as a child.
End note
I had meatloaf and scalloped potatoes for dinner.
