Replacing 30 grams per day of processed meat or seafood with vegetables or nuts and seeds is linked to higher levels of folate in the blood.
Mechanism
Synthesis from 1 study
Eating more vegetables and nuts instead of processed meat and seafood gives your body more usable folate, which it absorbs better and doesn’t waste as much. That’s why more folate stays in your blood.
Most probable mechanism
When people eat more vegetables or nuts instead of processed meat and seafood, their bodies absorb more folate from food because these plant foods are rich in natural folate. This extra folate enters the bloodstream directly, and since the body doesn’t need to break down as much processed food, less folate gets used up or lost, so more stays in the blood.
Dietary intake of natural folate from vegetables and nuts increases significantly due to substitution of processed animal products
Natural folate in plant foods is more bioavailable than synthetic or bound forms in processed meats and seafood
Increased folate absorption occurs in the small intestine via specific transporters that prefer unprocessed folate forms
Reduced consumption of processed animal products lowers intake of compounds that interfere with folate metabolism or increase its excretion
Net increase in circulating folate occurs due to higher absorption and lower metabolic demand or loss
