For years many people were taught that all dietary fat was unhealthy, but nutrition has become much more nuanced than that. The source of the fat matters enormously.
There is a major difference between fats found naturally inside foods like nuts, seeds, avocados, and olives versus highly processed foods engineered to be easy to overconsume. Whole food fat sources usually come packaged with fiber, micronutrients, and compounds that slow digestion and improve satiety.
One reason whole nuts behave differently than processed snack foods is something researchers sometimes call the “food matrix.” The nutrients exist together inside a complex structure that changes digestion, absorption, and fullness signals.
That is one reason nutrition becomes so confusing online. People often reduce foods down to a single number like calories or fat grams while ignoring how the entire food behaves inside the body.
I think many people would benefit more from focusing on food quality and dietary patterns instead of fearing entire macronutrients.
