The pickling process involves putting food into an acidic brine to produce a sour flavour, which is often considered a less healthy option than fermented foods.
Studies among older adults, however, have suggested that higher consumption of fermented tofu, temper and Tahoe, also worsen memory.
“Particularly, a high consumption of tofu, soybean and curd reduces the memory,” explained the authors of a paper published in Scientia Pharmaceutica in 2018.
One of the detriments of pickled foods is their high salt content, which can increase blood pressure post-ingestion.
