Macro partitioning
High-fat diets, particularly those high in saturated fatty acids, increase oxidative stress and mitochondrial dysfunction, leading to systemic inflammation and insulin resistance.
Reduce excessive consumption of high-fat diets, particularly those high in saturated fats, to mitigate oxidative stress and mitochondrial dysfunction. Be aware that not all fats are equal, but excessive intake contributes to inflammation and insulin resistance.
GoodSupportsHIGH confidence
A high-fat diet (HFD) was demonstrated to be a significant risk factor for health. Animals feeding a long-term HFD show increased oxidative stress and dysfunctional mitochondria in several organs.
Why this rating
Supported by systematic reviews, randomized trials, and animal studies, though some human data on SFA and CVD is mixed.

- High intake of refined carbohydrates and high glycemic index foods promotes oxidative stress and chronic inflammation via NF-κB-mediated signaling, contributing to insulin resistance and metabolic syndrome.Good
- High intake of processed meats, particularly those cooked at high temperatures, increases the formation of genotoxic and carcinogenic compounds like heterocyclic amines and N-nitroso compounds, contributing to oxidative stress and colorectal cancer risk.Good
