A few days ago, when I was on vacation, I went to a cafe to read a book and enjoy a leisurely life, and I happened to be sitting next to three old men who were chatting with each other (not that I wanted to eavesdrop, but the sound of the old men chatting was just too loud). One of them pointed to the afternoon tea they ordered, and the other two said that diabetes can be eaten without stressing about sugar, and then cut to the last time he went to hear an expert lecture on sexual dependence, which has a lot of claims with the doctor said differently, and then began to splutter with the other two uncle to instill these new claims, including the current recommendations are wrong, which is why there are so many chronic diseases, he went to the class to learn the new ideas He went to the class and learned new concepts, teaching that you need to drink more water, you can eat more oil, the pyramid should be upside down...etc..

In addition, this uncle also kept telling his friends some correct concepts of food choices, such as "all fats and oils come from seeds, so you have to use high tech to extract the oil...fats and oils are perishable so they have to go through a delicate treatment...so the rancid oil from the top X a while back is very safe because it's very pure, tested and has no problems, and is fully compliant with the national standards. There is no problem with the test, it fully complies with the national health standard, it is as pure as water, this is absolutely edible, people boycott Top X's oil because of political factors...(thousands of words are omitted below).

The more I listened, the more horrified I became. The horror is not that these kinds of misconceptions are often spread by people who call themselves the righteous ones. It's even more horrifying than the *** fishy and gossipy news in today's media, because the latter at best puts you in a bad mood, but the latter can get people killed.

What is the 'diet pyramid'?

"Positive" Diet Pyramids = Older Dietary Guidelines

The existing Food Pyramids are dietary guidelines provided by the United States Department of Agriculture (USDA) to the American public in 1992 (refer to Attachment 1), which were intended to help the American public on how to make the right choices of food. It is divided into four layers, from top to bottom are oil and sugar, meat and milk and other protein foods, fruits and vegetables, grains and roots, because the pyramid graphic is the upper tip and lower width.

So in short, the old pyramid diet is to encourage people to eat less oil, moderate intake of meat, eat more vegetables and fruits, to grains and roots and other starchy foods as the main food. The first of the top ten causes of death in the United States is cardiovascular disease, which is traditionally thought to be associated with excessive fat intake, so it's not hard to understand why this dietary advice came about in the first place.

The Harvard pyramid = an upgraded version of the old dietary pyramid

But then more and more food-related scientific research has found that fats are good and bad, and that not all fats are bad, for example, omega-3 fatty acids in fish oils and monounsaturated fatty acids in olive oils are good for cardiovascular health; in addition, they are good for the health of the body. Not all starchy foods are good, for example, delicate starch will make the blood sugar rise quickly, intake of too much of this kind of food will increase the risk of chronic diseases.
