Fatty Fish

One of the most popular sources of high-protein food is fatty fish. Additionally, they are abundant in vitamins, calcium, iron, zinc, and omega-3 fatty acids. Salmon and mackerel are two fatty fish that are great suppliers of omega-3 fatty acids.

Due to their ability to encourage the release of nitric oxide, which dilates your blood vessels and improves blood flow, these fats are especially beneficial for circulation. Omega-3 fatty acids also help to prevent platelets from clumping together in your blood, a process that can result in the formation of blood clots. Fish oil supplements have also been related to lower blood pressure and better blood flow to the muscles during and after exercise. For instance, large dosages of fish oil (4.2 grams per day for four weeks) dramatically increased blood flow to the legs after exercise in a study of 10 healthy men.
