"Next thing you know, they'll be saying eggs are good for you and butter better than margarine..."
Actually, Julia Child was saying that some 30 years ago... she warned specifically against margarine... and lo and behold, she was 100% right, at least when margarine was still made with trans fatty hydrogenated vegetable oils. Very bad stuff, those trans fats. Raise one's triglyceride and bad cholesterol levels about 30% or more.
Eggs? Like the commercial says, eggs have gotten a bad rap. They don't contain any more fat or cholesterol than a slice of chicken breast. Good food, in moderation.
The key to long life and good health seems to be a calorie restricted diet. Small wonder that most centegenarians seem to live in areas of the world that are not especially the most well-to-do - eastern europe, Asia, etc. Most likely they are on lower calorie diets for most of their lives, out of necessity and/or cultural practice. Here in the super sized America, we spend twice as much on health care as our equivalents in Europe but live shorter lives that are twice as unhealthy.
Forgot to add: antiperspirants are typically loaded with aluminum compounds. Some evidence that aluminum is higher in olfactory lobes of brains of Alzheimer's patients. Is there a connection? Best not to use spray antiperspirants until we are sure...
