Jun 12, 2023 by Natali Anderson

French fries are a very popular food commodity across many cultural backgrounds on Earth and as such they may be appreciated by long-term space travelers. The process of frying in hot oil is associated with complex heat and mass transfer along with the growth and detachment of water vapor bubbles. These phenomena are strongly affected by buoyancy and gravitational acceleration making the study of frying at space conditions a challenging task. In their...

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.
