If you’re pumping iron salmon could make you stronger. With 22 grams of high quality protein per three ounces, this smart catch provides the building blocks your body needs to re- synthesize muscle tissue after a tough workout. And that’s not all. Salmon is also nature’s number one source of vitamin D, a nutrient that many of us don’t get enough of. That can make it harder to build muscle according to a 2010 Osteoporosis International study which links low vitamin D levels to decreased muscle strength.
