While I've been one who has complained about the Great Fashion Conspiracy regarding pockets in women's clothing, men and women do have somewhat different nutritional requirements, based on size differences, differences in the amount of physical work they do, and hormonal differences. Body and muscle types also factor into it, but those are largely determined by one's genes.
Most of us have too much sugar and too much salt in our diets, and usually not enough fiber or protein. Many of us also have too much fat in our diets, but I know people who have been on ultra low-fat diets and that created problems for them. Everything in moderation!
I've been reading an interesting book, "Delicious" by Rob Dunn and Monica Sanchez, which talks about the effects taste buds have had on human diets and evolution. Among other things, it suggests that mammoths and mastodons were so delicious that our ancestors ate them to extinction. Cats do not have taste buds for sweetness, so they don't have a 'sweet tooth', unlike humans.
