Red meats like beef, pork, lamb, etc make some of the most succulent and irresistably delicious dishes.
Always choose pieces with the least fat content. Look for cuts with little marbling. Lean veal is a good choice for those who are trying to improve their dietary supply of iron without consuming too much fat. Aside from being rich in protein (which is necessary to maintain muscle mass while losing weight), redmeats are a good supply of zinc, fairly decent amounts of other resistance-boosting B vitamins, thiamine and potassium.
You would best eat redmeats with foods like potatoes, beans, and other vegetables that will add carbohydrates and fiber to your diet. These foods will also contribute magnesium and potassium to help control blood pressure.
As with any meat, keep portions modest to minimize fat intake.
