PS....I eat healthy and have most of my life, I exercise and have most of my life....never smoked....but, menopause almost killed me. My maternal grandfather died in his sleep of either a massive cardio problem or something similar (he was thin).....I will take vitamins because I think they help, and because people are DIFFERENT! As people age their abilities to process nutrients can change for the worse...IMHO...oh, and I have a doc who is a MD and ND....who does research and teaches....I’ll listen to him.
PS..PS...meant to say my grandfather was 50 when he died.
Genetic problems are separate from the issue of taking excesses of trace nutrients. The best that you can do is try to get proper nutrition and exercise--and NOT load up on supplements, which can do more harm than good. Heart disease and other circulatory problems run in my family, on both sides. So far, my longest-lived relative died when he was 81 or 82... the next longest-lived was 72. My sister has high blood pressure. I exercise and try to eat right, and I don't have any cardio problems. I never had high blood pressure, except when I had preeclampsia when I was pregnant. My resting heart rate is below 60. Maybe I was lucky and avoided getting the nasty genes that kill off other members of my family--I don't know.
The bottom line is still, either you get enough of the trace nutrients, or you don't. It's just like oxygen--either you get enough, or you don't; consuming more than enough won't make you healthier.
