Mechanism

Synthesis from 1 study

How it works

Eating more vegetables, fruits, and whole grains changes gut bacteria to produce compounds that block fat buildup around organs and lower inflammation. This happens regardless of cancer type or smoking history because the biological process targets fundamental metabolic and immune pathways common...

Most probable mechanism

In Simple Terms

Eating more vegetables, fruits, and whole grains changes the bacteria in the gut to produce beneficial compounds that reduce fat buildup around the organs and lower inflammation in the body.

Causal chain
1

Dietary intake of fiber and polyphenols from plant foods increases the abundance of beneficial gut bacteria and enhances production of short-chain fatty acids

Supported by evidence
which leads to
2

Short-chain fatty acids reduce intestinal permeability and prevent translocation of bacterial endotoxins into the bloodstream

Supported by evidence
which leads to
3

Reduced endotoxin exposure decreases activation of hepatic NF-κB and IL-6 signaling pathways

Supported by evidence
which leads to
4

Hepatocytes reduce synthesis and secretion of C-reactive protein into circulation

Verified by multiple studies
which leads to
5

Lower glycemic load from plant foods improves insulin sensitivity and suppresses de novo lipogenesis in visceral adipose tissue

Supported by evidence
which leads to
6

Visceral adipose tissue accumulates less lipid due to reduced lipogenesis and increased fat oxidation

Verified by multiple studies
which leads to
7

Reduced visceral fat mass decreases local secretion of pro-inflammatory adipokines such as IL-6 and TNF-α

Similar Assertions

In women recently diagnosed with breast cancer, eating more whole grains, fruits, and vegetables and less animal food is linked to 9.0% lower levels of high-sensitivity C-reactive protein and 8.6 cm² less visceral fat for every 10-point increase in a plant-based diet score.

In women recently diagnosed with breast cancer, a diet high in refined grains, fruit juices, and sugary drinks is linked to higher levels of inflammation and more fat around the organs compared to diets lower in these foods.

In women recently diagnosed with breast cancer, eating more plant-based foods does not change levels of key inflammatory markers, muscle mass, or fat under the skin.

In women recently diagnosed with breast cancer, eating plant-based foods that are whole and unprocessed is linked to less fat around the abdomen than eating any plant-based foods regardless of processing, and this link is stronger than simply cutting out animal foods.

Eating more whole grains, fiber, fruits, and vegetables is linked to a lower chance of developing colorectal cancer and a specific type of breast cancer, but studies that randomly assign people to different diets have not proven this link with statistical certainty.
