The way people in wealthy Western countries eat has shifted dramatically. This change has led to some surprising and worrying trends. Body heights are dropping, obesity rates are soaring, and even intelligence levels might be taking a hit.

To understand this, let's look at the facts. For about 150 years, people in these countries were getting taller. Then, suddenly, this trend reversed. This change happened around the same time that dietary guidelines started pushing for less fat. These guidelines led to a drop in the consumption of eggs and red meat. Instead, people started eating more cereals and poultry. This shift also meant a decline in the quality of protein people were getting. Overall, diets became higher in glycemic load, which means they had more sugars and starches that break down quickly.

The results of these changes are clear. Obesity and type 2 diabetes rates have skyrocketed. These issues are closely linked to the increased consumption of high-glycemic carbohydrates and sweeteners. But here's where it gets even more interesting. The decline in body height is also connected to these dietary changes. A high-quality diet during adolescence can actually help prevent obesity. So, the drop in height might be a sign that children aren't getting the nutrients they need to grow properly.

Now, here's a thought-provoking angle. There's a long-term link between height and intelligence. So, if children aren't getting the right nutrients, it could affect their intellectual potential. This could have serious implications for future generations. It's a stark reminder that what we eat doesn't just affect our bodies in the short term, it can have long-lasting effects on our health and even our minds.

All of this raises some important questions. Are the current dietary guidelines really working? Should we be rethinking our approach to nutrition, especially for children? It's clear that the choices we make about food have far-reaching consequences. It's time to take a closer look at what we're eating and why.
