When I was a kid back in the 1970s, there used to be a bizarre and very short commercial on the TV from time to time. A panicky man would wave his arms at the camera and yell,

Women's Lib is taking over!
Eat sardines from Norway!

And that was the whole commercial. Even as a small child I recognized this as a very abnormal thing, and I'm eternally grateful for having been granted a glimpse of it while I was still young enough to be impressionable. Every child needs some surrealism. Hell, so do the rest of us.

Sardines are small fish which are often packed with oil or tomato sauce into small flat cans. Like most fish, they are excellent sources of omega-3 fatty acids, which lowers cholesterol level and thus your risk of heart disease, and keeps your immune system, as well as your skin and hair, in good shape. Because of the soft bones, one tin of sardines has more calcium than a glass of milk. In addition, fish are one of the few natural sources of vitamin D. Together, calcium and vitamin D help keep your bones strong and osteoporosis-free. And sardines contain iron. All in all, a good source of some necessary nutrients.
