Wild raspberries, although smaller and sourer than their supermarket counterparts, are believed to have higher nutrient density. Studies indicate a possible decrease in nutrient density in rapidly grown foods, linked to lower absorption rates in the body. As the absorption of flavonoids from the diet is around 10%, a reduction in nutrient density could result in reduced availability of beneficial compounds. This reduction may impact the inflammatory and neuroprotective effects of these compounds, leading to potential health implications such as brain fog. Other factors associated with brain fog include poor sleep.
