A gyre is another name for a swirling vortex. Ocean gyres are large swirling bodies of water that are often on the scale of a whole ocean basin or 1000 s of kilometers across (hundreds to thousands of miles across).
Lean meats are meats with a relatively low fat content. Skinless chicken and turkey and red meat, such as pork chops, with the fat trimmed off are examples of lean meat.
Lean red meat contains the same amount of cholesterol and close to the same amount of fat as lean chicken, fish, and turkey. If the red meat doesnât say lean, buy dense cuts, such as top round, or any red meat that looks lean, such as tenderloin, London broil, ham, or Canadian bacon that has no visible fat.
