Something that's always confused me is how I get powerful cravings for sugar, but am relatively untempted by salty foods or carbohydrates, wheras my sister(very close in age to myself) isn't tempted at all by sugar but is a sucker for salty foods. We grew up in a presumably quite similar culinary environment. I've often wondered If the differences can be explained by gut bacteria.
Also, surely the claim that this is the first study to show a link between gut bacteria and food choice is wrong? I'm pretty I've known about the link for years?
I’m pretty sure sugar cravings in my family are simply garden variety hunger. For us “sweet tooth” mostly correlates with missed meals. The brain runs on glucose, so when the body is low on food and blood sugar dips, sugar is the “quick fix” for the brain.
