Cranberry Product Consumption Reduces Risk of Symptomatic UTIs in Women

Apr 20, 2023 by Enrico de Lazaro

Cranberries — as cranberry juice, tablets or capsules — have been used for many years to prevent urinary tract infections (UTIs). They contain proanthocyanidins, substances that can prevent bacteria from sticking to the walls of the bladder. This may help prevent infections and reduce the need for working people to take time for medical appointments. However, there is currently no established regimen for what proanthocyanidins dose to...

Using an interventional study in healthy, normal-weight participants, Thanarajah et al. demonstrate that, independent of body weight gain and alterations in metabolic markers, exposure to high-fat/high-sugar food: (i) reduces preferences for low-fat food, (ii) plays a critical role in up-regulating brain responses to anticipation and consumption of highly palatable, energy-dense food, and (iii) has a generalized effect on the neuronal encoding of prediction errors in the context of associative learning and independent of food rewards. Taken together, repeated consumption of high-fat/high-sugar relative to isocaloric low-fat/low-sugar food, and in the absence of changes in body weight or metabolic state, can rewire brain circuits and thereby induce neurobehavioral adaptations. Hence, changing the food environment and reducing the availability of energy-dense high-fat/high-sugar food items is pivotal to combating the obesity pandemic.
