What's the beef with meat? This question can be answered in two nutritional words: fat and
cholesterol.
Too much fat. No matter how you slice it, meat is high in fat. Unlike milk, in which you can
separate out part or all of the fat, you can never get rid of all the fat in meat, no matter how well
you trim it. Even the lean parts are laced with fat. Extra lean select-grade beef contains around
seven percent fat.
Wrong fat. Not only is there too much fat in meat, it's the wrong kind. Nearly half the fat in
meat is the artery-clogging, saturated type. And, of course, meat is also high in cholesterol. Beef
fat is more saturated than poultry fat because the bacteria in the ruminant stomach of cattle
hydrogenate, or saturate, the fats in the plants that cows eat. It's like having a fat factory inside
the food source.
Fat without fiber. Unlike meat, plant foods that are low in fat and high in fiber tend to pass
through the intestines rapidly, causing less upset and fewer problems, such as gastroesophageal
reflux. Meat has a double fault. It's high in fat and contains
no fiber, so it takes longer to empty from the stomach and pass through the intestines. While
most people do not experience "indigestion" from meat, those who suffer from reflux should not
eat much meat, as it may aggravate the problem.
Problems with protein. Not only are the fats in meat unhealthy, meat proteins have also
recently come under fire. Recent evidence suggests that animal proteins increase blood
cholesterol levels, while plant proteins, especially soy, decrease them. Meats contain high levels
of the amino acid L-lysine, which increases insulin production,
prompting the liver to release fat and cholesterol into the bloodstream. If L-lysine is
experimentally added to animal diets, blood cholesterol levels increase by over fifty percent and
the animals get plump. Studies show that substituting 30 grams of soy protein daily for a meat
meal dramatically reduces cholesterol levels. So, the Japanese may have lower cholesterol levels
than Americans, not only because they eat less meat, but also because they eat more soy. The
quality of meat protein ranks below that of egg white, fish, and dairy products.
Other concerns. While there is experimental evidence to implicate the meat fats and proteins in
meat with disease, the effects of muscle-building hormones and infection-killing antibiotics fed
to livestock are harder to pin down. These substances appear in the meat at the supermarkets,
and common sense tells us they certainly can't contribute to our health and may harm it.
The most compelling reasons for going meat-less are the undisputed studies showing that
countries with higher meat consumption rates also have higher rates of heart disease and
cancer. And within these countries people who eat less meat have a lower incidence of both
heart disease and cancer than the general population. One of the most famous studies is called
the Nurses' Health Study. In this study of more than one hundred
thousand female nurses, those who ate the most animal fat were twice as likely to get colon
cancer as those with the lowest intake of animal fat.
You may not want to completely eliminate meat from your diet, but there are ways to cut back on
both the meat and the fat.
Trim the fat. Trim all the fat you can see surrounding that sirloin. In addition, choose cuts
of meat that are less marbled with fat, the kind of fat that not even the finest surgeon could trim.
Since there is no law requiring beef to carry these labels, you may have to ask which category of
meat a particular cut is. Here are some fat-trimming words to look for in reading labels on cuts
of meat:
Select is the leanest cut of meat, containing around 7 percent fat by weight.
Choice contains 15 to 35 percent fat by weight.
Prime is the fattest grade, containing 35 to 45 percent fat by weight
Fat content will vary with different cuts of meat, as well as with the grade. Here are different
cuts of select-grade beef in order from lowest fat content to highest.
top round
eye of round
round tip
bottom round
shank
sirloin
arm
top loin
t-bone
tenderloin
porterhouse
brisket
rib-eye
flank
ribs
blade
Drip-dry the fat. Broiling is likely to remove more fat from the meat than frying, especially
if the fat drips out of the meat. Roasting or baking the meat in its own juice is certainly better
than adding fat by frying, yet the fat can soak back into the meat this way.
Instead of buying hamburger, choose the leanest piece of beef you can find, such as select lean or
select top round (around four grams of fat per 3.5 ounces compared with 18 grams of total fat for
lean ground beef) and ask the butcher to grind your chosen cut into hamburger for you. (Of the
popular cuts of beef, select top round has the lowest amount of total and saturated fat.)
Beef up the main dish without beef. Rather than making meat the centerpiece of a meal and
vegetables the accent, reverse the importance of these foods. Dicing up three ounces of beef into
a vegetable stirfry is much healthier than sitting down to a 16-ounce sirloin. Instead of planning
meals around the meat, let the meat accompany the vegetables or be part of a pasta or grain-based
casserole.
Consider other meats:
Game meats. Game meats are the lowest in both total fat and saturated
fat. Some have one-fifth to one-twentieth the fat contained in domestic meats. For example, 3.5
ounces of venison contain only three grams of fat, one of which is saturated. Rabbit meat is
higher in vitamin B-12 than any domestic meat, supplying six micrograms, 100 percent of the
recommended dietary allowance.
Veal. Though veal is higher in cholesterol than many cuts of beef and contains
about as much fat, it is much higher in niacin (a 3.5 ounce serving contains 10 milligrams, half
the RDA). In addition, veal contains two to three times more calcium than most cuts of beef or
pork. If possible, buy free-range veal.
Lamb. Depending on the cut, lamb is nutritionally similar to beef. It's slightly
higher in niacin than beef, except veal.
Pork. There is no nutritional advantage to eating pork over beef. It is lower than
most cuts of beef in vitamin B-12, zinc, and iron. Avoid fatty processed meats, such as bacon
and sausage; they not only contain lots of saturated fat but also may contain nitrates.
