Our food chain has a lot to do with obesity. There are many studies on this stuff.
We eat 5 times as much meat on average as people did 100 years go. Animal based products are a major source of fat. People used to eat more fruits and vegetables. The fat type has shifted with more fat (which has higher calorie per gram amounts than carbs or protein) and fat moving from polyunsaturated fats to saturated fats (which causes lots of medical problems).
In there is the growth hormone. Kids "mature" physically at younger ages now than they used to. Kids to stop stop dairy or a lot of mean may physically mature at the older slower pace.
Eating less fruits, vegetables, and whole grains means less fiber. Most people (in the US anyway) are deficient in fiber. Fiber traps certain fats and cholesterols so they aren't absorbed. So, we absorb more fats.
Then there are processed foods.
So much about our diets have changed in the last 100 years. A lot is known and we even know how to eat to be really healthy. It's just not widely known by the general public.
- inglor_cz 4y agoYour comment completely ignores the content of the article you are commenting upon. You concentrate on the "normal" nutrition stuff like fat, fiber and carbohydrates, without even asking why do people eat more than 100 years ago. The article talks about the fact that food now contains a lot of totally unnatural chemical substances that our ancestors never encountered and that such substances may throw off our sense of satiety and disrupt other mechanisms directly related to obesity. That is a serious problem. An apple or a piece of meat laced with various chemicals isn't the same as 100 years ago. It seems you choose to ignore this difference.
- reedjosh 4y agoWe eat unnatural amounts of polyunsaturated oils today. You have it completely backward. The amount of vegetable based fats consumed 100 years ago was significantly less. It wasn't until chemical extraction was introduced that we could consume as much vegetable based fat as we do today. Saturated fat is actually more stable and by far healthier.

- olddustytrail 4y agoI'd rather trust the expertise of doctors who've actually studied this stuff than a moron journalist, thanks.
- reedjosh 4y agoYou're sure fun to chat with.
- olddustytrail 4y agoYour idea of fun is to post ignorant crap on medical issues? Your type were boring when I was 20 and even more boring now. I teach people and create things for fun. Grow up.
- adrian_b 4y agoWhat you say is correct, but incomplete. The unnaturally high consumption of PUFA is not for all kinds of PUFA, but mainly for linoleic acid and related fatty acids (a.k.a. omega-6 acids). The consumption of the other main kind of PUFA, omega-3 acids, is frequently lower than before, as those are abundant mainly in some animal organs (which are more seldom consumed now) and in fish. In small quantities linoleic acid is an essential nutrient for humans, but in large quantities it must be converted into other fatty acids, because it is not a normal component of human fat, and that can be a burden for the liver.
