Macro partitioning
Omega-3 polyunsaturated fatty acids (PUFAs) and other unsaturated fats inhibit Toll-like receptor 4 (TLR4) activation and pro-inflammatory cytokine release, thereby ameliorating chronic inflammation driven by saturated fats and LPS.
To support a healthy immune response that can resolve inflammation effectively, prioritize unsaturated fats, particularly Omega-3s. These fats actively inhibit inflammatory pathways like TLR4, counteracting the pro-inflammatory effects of saturated fats found in typical Western diets.
GoodSupportsHIGH confidence
On the contrary, omega 3 and PUFAs can interfere with TLR4 activation through inhibition of COX-2 mediated prostaglandin release and thus ameliorate this inflammatory signal (24, 25).
Why this rating
Supported by multiple citations (24, 25, 26, 27, 28, 29) in the review.

More from this paper
- High intake of dietary fructose (common in Western diets) metabolically rewires innate immunity by increasing mTORC1 activity and IL1B expression in monocytes/macrophages, thereby promoting a pro-inflammatory state and reducing metabolic flexibility.Good
- Very-low-carbohydrate diets enhance human T-cell immunity by inducing ketone body production (specifically beta-hydroxybutyrate), which reprograms T-cells to favor oxidative metabolism, improves cellular energy supply, and increases T memory cell formation.Good
- Obesity and the associated accumulation of bone marrow adipocytes disrupt normal hematopoiesis and immune function by creating a pro-inflammatory environment mediated by TLR4 activation, leading to impaired immune responses and increased morbidity/mortality during infections.Good
