Through the first pandemic lockdowns initially of 2020, social media was flooded with footage of home made banana bread as folks turned to baking in lieu of socialising. Now with many locations reintroducing or anticipating additional restrictions as COVID-19 case numbers rise once more, there’s a superb likelihood we may see a revival of the house baking development, not least as a result of the primary banana bread craze had some robust psychological roots.
Our meals preferences, acceptance and consumption are formed by household and buddies, promoting, celeb traits and, as of late, social media influencers. It’s smart to be guided by others’ information when errors carry probably deadly penalties. This “social studying” prevents spoiled or toxic meals consumption.
Our modelling of others’ behaviour is especially robust when following somebody we admire, reminiscent of these we observe on social media. And we frequently flip to modelling to cut back uncertainty, which was rife in the course of the upheaval of the primary lockdown due to a lack of understanding in regards to the coronavirus.
However why banana bread? Our brains developed when shortage was frequent. Sources of sugar have been topic to seasonal availability and strategies for storing perishable fat have been restricted. Bingeing opportunistically on these biologically vital vitality sources once they have been obtainable was sensible.
The essential nature of meals to our survival makes it inherently rewarding. Even sight or scent of meals triggers a response within the mind’s reward system. All meals will not be equal, nonetheless, with the strongest hedonic response for the mix of sugar and fats.
We’ve got innate choice for candy meals, which elicit a response as potent as that triggered by cocaine. Satiety does little to decrease motivational drive for sweetness – we may be full from a big meal and nonetheless have room for dessert.
Nearly as good as the true factor
However banana bread was in our social media feed, not in entrance of us. Gaining as a lot info as we are able to about meals earlier than placing it in our mouth is important to guard us from hurt. We use visible and olfactory enter and social affect as cues to meals availability and worth, rising our motivation to eat.
That is disproportionately so for palatable meals, these tempting gadgets filled with carbohydrates, fats and salt. Their photos can set off cravings, salivation and digestive responses.
The best way we be taught to affiliate a stimulus (banana bread) with its consequence (pleasure or satiation) means we truly obtain the reward response, a burst of dopamine, in anticipation from sensory cues, somewhat than throughout consumption. In our trendy setting, these cues, reminiscent of Instagram posts, may drive our food-seeking behaviour much more strongly than indicators of starvation.
The act of baking may be particularly potent as a result of our olfactory cortex is extremely interconnected with areas processing emotion (amygdala) and reminiscence (hippocampal cortex). Odor can evoke vivid autobiographical reminiscences and feelings related to them. It may additionally decrease coronary heart charge, cut back stress and nervousness and enhance psychological and immune operate.

Simply as a madeline cake induced creator Marcel Proust to relive a childhood reminiscence in his autobiographical novel In Search of Misplaced Time, optimistic childhood reminiscences of baking may be evoked by the scent of banana bread within the oven. This sense of consolation or happiness may be simply what we would have liked throughout lockdown, particularly for these other than household.
The emotional turbulence of lockdown can be influential. Stress and low temper can set off meals cravings, particularly for carbohydrates and fat-laden “consolation” meals.
Stressors enhance consumption of consolation meals and enhance motivational worth of those meals, making us need them extra. Stress will increase ranges of the hormone cortisol, rising urge for food and (consolation) food-seeking behaviour by decreasing the consequences of leptin, a hormone signalling fullness.
Lockdown additionally affected folks’s sleep, resulting in reviews of vivid, weird desires and elevated daytime sleeping. Sleep is vastly influential on urge for food and consuming behaviour. Like stress, sleep deprivation is related to palatable meals cravings.
Day sleeping is especially harmful, because it reduces melatonin secretion. We secrete melatonin when it begins to get darkish, to help sleep and enhance leptin sensitivity. Decrease leptin ranges end in larger insulin and cortisol ranges (our previous buddy the stress hormone), rising starvation and meals looking for.
So for those who punish your self for snacking by way of boredom, these additional lockdown kilos may not point out lack of self-control. A mixture of evolutionary, social, and motivational forces form the way in which our mind makes use of sensory indicators indicating meals availability to manage our urge for food and consuming behaviour.
After we are drained, careworn, or unsure, Instagram banana bread photos, signalling the heady mixture of sugar and fats, may be simply the cue we have to get us off the couch and into the kitchen. Now the place did I put my spatula?
