What about tenderness? Government grading specifications indicate that intramuscular fat and tenderness go hand in hand. Is that true? For the answer, check this out: The Meat Tenderness Debate.
Compositions of Foods
"CLA is a fatty acid found in beef and dairy fats. Scientific interest in CLA was stimulated in the late 1980s when a University of Wisconsin researcher discovered its cancer-fighting properties in a study of rats fed fried hamburger. CLA cannot be produced by the human body, but it can be obtained through foods such as whole milk, butter, beef, and lamb."

Eat meat. That's the dietary advice given by a team of scientists who examined the dietary role of fat in a study that combined nutritional analysis with anthropologic research about the diets of ancient hunter-gatherer societies. The article is titled Cavemen Diets Offer Insights to Today's Health Problems.
Even though this study used grain-fed meats, it proves that even a little of the low-grain approach works best. The Atkins Diet doesn't emphasize grass-fed meats. If it had, the meat eaters in this study would have lost considerably more weight. But just the same, this study provides some guidance about how one should eat. The link takes you to an article summarizing the research. In that research you'll see that the low-fat, restricted-calorie diet based on the American Heart Association's guidelines was worse than the Mediterranean Diet.

Grass-fed beef, because they are not finished on corn full of omega-6 fatty acids, will be better for you than conventionally produced beef. Grass-fed beef actually contains omega-3 fats from the grass, though not in as much quantity as you would get in a cold-water fish. This is a short but informative article about the benefits of grass-fed beef by Carolyn M. Matthews, M.D.
The foods that humanity originally evolved to eat and those we now eat in modern civilization are in many cases significantly different--yet our basic underlying genetic inheritance remains basically the same as it was before, and has evolved only very slightly since then. Thus, many of the foods we now eat are discordant with our genetic inheritance. The principle of evolutionary discordance.
Raw red muscle meat contains around 20-25 g protein/100 g. Cooked red meat contains 28-36 g/100 g, because the water content decreases and nutrients become more concentrated during cooking. The protein is highly digestible, around 94% compared with the digestibility of 78% in beans and 86% in whole wheat. (9) Protein from meat provides all essential amino acids (lysine, threonine, methionine, phenylalanine, tryptophan, leucine, isoleucine, valine) and has no limiting amino acids.
