The world is undergoing a "nutrition transition". In a nutshell, this term refers to changes in people's diet as their country's wealth increases. This shift is super interesting because it isn't the same everywhere! Countries at different stages of economic development have varying food consumption patterns. Don't believe me? Keep reading!

Let's start with LICs like Bangladesh. Here, most of the food energy comes from carbohydrates (around 80%), with a tiny bit from fats (about 11%). Meat and dairy? Almost zilch! So, we're talking about a rice and plant-based diet here, with hardly any steak or cheese in sight.

On the flip side, in HICs such as the US, France, and Denmark, things are pretty different. These people get roughly 45-50% of their energy from carbohydrates, but also a whopping 40% from fats. Meat and dairy play a big part too. Imagine a typical meal being a juicy burger with a side of fries and a milkshake!

This transition from a carbohydrate-heavy diet to one including more fats, meat, and dairy has been happening for 300 years, initially in developed countries. As LICs start to earn more, even a small bump in income can lead to a significant increase in calorie intake. However, in HICs, more money doesn't necessarily mean more calories. Kind of like how your 10th chocolate bar doesn't taste as good as the first, right?
