Europe hasn't avoided the dietary changes occurring in the US, it's just that the effect is less pronounced. European portion sizes are growing as well, but not to the very generous sizes I experienced in the US. There is less added sugar in European food - bread does not generally taste sweet in Europe, but it does in the US (to me anyway). Europe also does not use much (any?) high fructose sugar.

That being said, Europe is not immune to expanding waistlines. The UK is not far behind the US in obesity and overweight population. It is a similar story across the rest of Europe.

I think the key differences is that Europe has avoided the opioid crisis the US is experiencing, and the US suicide rate is also much higher. But other deaths rates, such as from alcohol abuse and obesity, are comparable between the US and the UK.
