Why Canned Soup Ironically Dehydrate You
Canned foods are salt bombs in a container. To preserve the products, manufacturers add extra sodium. Harvard Health explains that salt absorbs liquids in the digestive tract. The result? You end up more dehydrated after eating canned foods than eating fresh foods.
Even water-filled foods, such as fruits and vegetables, can be less hydrating if they’re canned. You can remove some sodium by rinsing the food (depending on what it is). But in general, you shouldn’t resort to canned foods or soups if you’re feeling thirsty.
