Would like more clarification on the saturated fats front, though (compare coconut oil, butter, palm oil, trans fats).
Here is one instance of an easily accessible peer-reviewed-science-based list of the current knowledge on dietary fat: https://www.foundmyfitness.com/news/t/fat
It does not show that oils or fat are something to blanket avoid.
That doesn’t say much about what kind of fat we’re eating (e.g., if it’s oil), but the advice to reduce calories from fat was based on them being empty calories. It appears that they also help people feel full longer.
Personally, when I eat a salad for lunch, it doesn’t bother me that literally 85% of the calories come from fat (15 calories for the lettuce, 90 calories for the salad dressing). Even if I have low-fat salad dressing (30 calories), I’m getting 66% of my calories from fat.
Then again , maybe I’m reading the data wrong: it’s possible to reduce the percentage of calories coming from fat by eating the same amount of fat, and more food overall. Maybe Americans just did that.
