My views now. There is no healthiest diet for everyone. People have individual needs. And those needs change as we get older or go through different phases of life. But I think if you eat a diet with an emphasis on green vegetables, fruits, whole grains, nuts, and seeds every day, then you can include some animal foods without dying young. Just make sure your weight and blood values are good. If not, adjust something, experiment. Wild salmon is probably the best animal source, but there are still concerns about mercury. Sardines are healthy, if you can stand them. Veganism is definitely not for everyone. But the best thing people can do for their health and weight is not to eat anything with added sugar, corn syrup or refined flour products. That’s a challenge for most people, since everything with an ingredient label has added sweets. Fine, stop eating things with labels. I don’t. Not even salad dressing; I make my own. The more you can cut out those sweets, the healthier you will be.
