After having so many people tell
me that they’ve given up red meat because of their cholesterol levels or
because they couldn’t lose weight, I wanted to say something about it. Before I do, though, I first want to
preface this with a couple of points:
1. If you’ve given up eating red meat (or any meat or animal products for
that matter), for ethical, environmental, or another reason non-diet related,
then this information wouldn’t apply.
2. When I talk about eating meat/fish, ideally it’s grass-fed,
pasture-raised, or wild caught; free from added anything, including hormones,
antibiotics, pesticide from soy or corn feed–which are also genetically
modified. This also implies that
the animals have been raised humanely.
In an
article written by Gary Taubes that was published in the Journal Science
back in 2001, he raised the complex nature of fat in the diet and made these
points:
- while saturated fats raise LDL-C (which is plaque building and associated with increased risk of coronary artery disease), they also raise HDL-C (which is good);
- some saturated fats, like stearic acid, found in chocolate are considered neutral because they raise HDL-C and do little or nothing to LDL-C; (a more recent review of stearic acid reported that it lowered LDL-C and was neutral with respect to HDL-C);
- monounsaturated fats are beneficial because they raise HDL-C and lower LDL-C;
- trans fats are bad because they raise LDL and lower HDL
He then goes on to show how this
complexity can be applied to a select cut, porterhouse steak with a
half-centimeter layer of fat (nutritional info can be found on the USDA website
here). After broiling this piece of meat, it
reduces to almost equal portions of fat and protein.
- 51% of the fat is monounsaturated (90% of this is oleic acid - the same healthy fat found in olive oil);
- 45% of the fat is saturated, but 1/3 of that is stearic acid (the same fat found in chocolate, which is harmless);
- the remaining 4% is polyunsaturated fat, which improves cholesterol levels
This means that over 70% of the
fat in this steak will improve cholesterol levels. And, if this
study was performed on a feedlot piece of meat, then the beneficial, omega-3
fatty acid profile may be understated compared to beef from a grass fed
cow. Think about what a
porterhouse steak meal would look like if you added potatoes, bread, rice, or
pasta to it. Now, you’ve added
foods that will raise your insulin and promote
fat storage. Is it
possible that this steak is guilty by association? Do you
think that same piece of meat would be involved in fat storage if it were
served with a plate filled with non-starchy vegetables and a fresh salad? I don’t.
Does this mean that I’m telling
you to stock your freezer with beef and eat burgers everyday? No. For myself, I actually eat meat only occasionally, but I do
it without fear. But having this
information will allow you to make informed decisions if you choose to reduce
your animal product consumption, which I do think most of us should do, or
decide to remove it altogether from your diet.
