Dietitians' Recommendations: Progress, but Cognitive Dissonance

The Academy of Nutrition and Dietetics has officially acknowledged well-founded scientific findings(1).  Specifically,


  • Saturated fat is fine.
  • Cholesterol is fine.
  • Red meat has important nutrients, such as protein and iron. They call red meat an "important source of shortfall nutrients, such as iron." They add, "The Academy did not interpret that recommendation as impugning the healthfulness of red meat or its place in recommended meal patterns as a protein..."


Hooray! The fifty pounds of angus beef in my freezer has their blessing! They even called it healthful!

But wait--don't eat too much of it: "...red meat consumption [at an average of 20 ounces per week] exceeds [our] recommendations for most subgroups and...a greater share of recommended protein consumption should be met by seafood, legumes and nuts."

Let's break this down: red meat is entirely, or almost entirely, fat and protein. If protein is good, and saturated and monounsaturated fat (the two main types of fat in beef, for instance) are good, where's the problem? They don't say, so let's take a look at a few nutrients in some common types of red meat, fish, legumes and nuts.

protein (g)carbs (g)iron (%DV)calories
ground beef, 75% lean, pan fried26015277
pinto beans (cooked)93115162
almonds221925597
salmon2606149
*per 100-gram serving


The beef, almonds and salmon score well for protein, but pinto beans are over three-quarters carbohydrate, which (except fiber) breaks down into sugar in the body. It's hard to see how such a starchy food that's low in protein (it's only 20% protein) is considered a good protein source. Almonds are three-quarters fat and only 13% protein--hence the high calorie level. Salmon is three-quarters protein and the 75% lean ground beef is 41% protein.

If you replace 200 grams of red meat (7 ounces, or 2 medium-sized burgers) with 100 grams of almonds and 100 grams of pinto beans, you'll get 21 fewer grams of protein, 50 more grams of carbohydrate, and 205 more calories.

Since the Academy mentioned iron as a shortfall nutrient, let's look at iron levels in these foods. Everything except salmon has a good deal of iron in it, but the trouble with nuts and beans is that they contain phytate, which inhibits your absorption of various minerals including iron. In other words, much of that wonderful iron from nuts and beans will go down the toilet undigested. Iron absorption from various beans is around 1% to 2%; same for nuts. If you replace a couple of hamburgers with an equal weight of beans and nuts or even salmon, you'll be reducing significantly reducing your iron intake.

It's time official agencies acknowledged that red meat is healthy. Meantime, it means more burgers for me.

Iron has to be in meat form to be well absorbed...at least for most people. When i was a fat Vegan I was anemic. I ate all the iron containing foods allowed. I gave that up and ate red meat and within a month my anemia went away. I know it's just my response but it happened to my sister, too. My Mom eats no meat and is anemic. She refuses to eat meat to fix the problem and likely will go the same path as my Dad...dying with heart failure. Sadly.

After reading your comment from the last post, I started to double down on my iron supplement, and felt a lot better--my heart felt like it was working normally. Had a grass-fed burger and felt wonderful, too.

Sorry to hear about your parents. Maybe vegetarianism is one reason heart disease is so common in India.
I may not win 100% of fans here, and how anyone chooses to eat is a personal choice, but I do think meat should be included within our menu plans along with fish too.

Vegetables form an important part of my menu plans too as does dairy.

To me the most important thing that needs to be greatly reduced in our diets/ menu's are the processed foods.

We still have a way to go with the recommendations ...

All the best Jan

I totally agree, Jan--meat, vegetables and fish all have important nutrients.

Great post. The recommendation of these poor, not to mention high-carb,non-animal sources of protein is bewildering. Eating animals is what's gotten us here as a species. Yo.

Still, thankful for small steps in the right direction. I suspect reversing the 1980 Guidelines that started it all will be like turning around a cruise ship in a harbor - many many many tiny turns.

If they don't turn the ship around, it will run into an iceburg called type 2 diabetes expenses.

Moving on to YouTube

Remember when the blogosphere was a wild ride? Doctors, writers and researchers dove into research, picked apart studies and stood up to official advice and conventional wisdom that didn't work. We found each other in the comments and made a community.  Along the way, Dr. T. Colin Campbell's research got exposed as shoddy by an English major, Tom Naughton made us laugh, "safe starch" fads made us scratch our heads, "Diabetes Warrior" Steve Cooksey almost went to jail, CarbSane trolled everyone who was anyone, and CarbSaneR trolled the troll.  Now it's very quiet. Blogs don't come up in Google search results anymore and even if they did, most of the bloggers have stopped writing.  That's why I've moved on to YouTube. Videos do come up in search results and my shorts--which are mostly what I make--get pushed out to hundreds of people or more. My videos are on food and health (biohacking), but also on growing things and fixing things. If you...

We Hate the ADA; Why does the Perfect Health Diet Get a Pass?

Some people keep touting the Perfect Health Diet as low-carb, but carb levels that are mostly in the triple digits aren't generally regarded as low-carb; in fact, one of the authors says low-carb diets are unhealthy. A lot of us hate the  American Diabetes Association's advice for diabetics: start with 45g to 60g of carbohydrate per meal and go higher or lower from there. That's 135g to 180g of carb. Perfect Health Diet advice for diabetics: eat 20% to 30% of your diet as carbohydrate. On 2,000 calories, that's 100g to 150g of carb. On 1,700 calories, that's 85 to 128g; on 2,200 calories, that's 112 to 168g. Depending on your carb and calorie intake, carbs would be 85g to 168g per day. That's not a mile off from the ADA's recommendations. Paul Jaminet, one of the authors of the Perfect Health Diet, says, "the basic biology here is that the body's physiology is optimized for a carbohydrate intake of about 30%." He warns against a ...

Palpitations Gone with Iron

Thanks to my internet friend Larcana, who alerted me to the connection between iron deficiency and palpitations, I doubled down on my iron supplements and, for good measure, washed them down with Emergen-C. It's a cold medicine with a mega-dose of vitamin C, plus B vitamins and minerals. I don't think vitamin C does anything for a cold (a friend bought the stuff and left it at my house the last time she visited), but vitamin C does help iron absorption. After doubling up on iron in the last three days, I feel back to normal. (I'd already been taking quite a bit of magnesium and potassium, so I probably had sufficient levels of those.) How did I get so low on iron? Maybe it was too many Quest bars instead of red meat when I had odd cravings during my dental infection recently. Maybe because it's too hard to find liver at the grocery store and I haven't eaten much of it lately. Maybe the antibiotics damaged my intestines . And apparently, I'm a heavy bleeder . ...

Not Only Cheaper, But Easier

A while back, I wrote about saving money on break time coffee and snacks. I haven't done very well putting it into practice. But a post by James Clear today got me thinking about it again: Warren Buffett uses a two-list system to prioritize things. Check it out --and follow the instructions. Using Buffett's two-list system, two of the goals I ended up with were taking care of myself and saving $400 more per month than I already am. As I said, I've been wanting to save money, and the system made me really focus on this. I came up with 11 money-saving ideas, six of which had to do with food. Buying hamburger in bulk. Ranch Foods Direct sells one-pound packages of 80% lean pastured ground beef in bundles of 20 for a lot less than Whole Foods. Sprouts only carries super-lean beef that's grass-fed, and it's more expensive, too.  Not driving to Whole Foods. Whole Foods is out of my way, and saving a weekly trip saves gas. Coffee at home, tea at work. Tea is fr...

Doing Old-School Atkins

Last time I wrote about getting jittery and having a rapid heartbeat on VLC (very low carb). I cut way back on nuts a few weeks ago and felt remarkably better: more energy, and I can tell I lost a little weight because of the way my shoes and watchband fit. As I mentioned, taking a potassium pill helps the jitters and rapid heartbeat, and if it gets really bad, I can just eat a candy bar (we don't have safe starches at work). So for the first time, I tried Atkins induction. Why Atkins induction? It started with shorts. I'd been shopping for shorts and everything was very short (think Officer Jim Dangle on Reno 911 ), wildly patterned, ridiculous (where do you wear lace shorts if you're not starring in a Korean drama?) or knee length. There was even a high-waisted, pleated, acid washed pair from circa 1985. So when I saw a gray pair with sailor pant buttons, I bought them--even though they were pretty short (but not tight). Think Officer Dangle again. Being conscious of wea...
