No, that’s not a typo. Although sardines have long been a niche snack, they’re now being presented as one of many solutions to the overfishing crisis. Studies have shown that three-fourths of the world’s fish stocks are being harvested faster than they can reproduce—meaning we will eventually run out of tuna, swordfish, halibut and more, unless we change our behavior. But because sardines remain in abundance, and a group called the Sardinistas is trying to reintroduce them as a mainstream diet staple. It’ll be a rocky road, no doubt, but they already have dietician approval: sardines are high in omega-3 fatty acids, which help your metabolism and can lower blood pressure.
