Diet: It Just Doesn’t Matter

/in /by

Long-time readers probably know I love using quotes from movies. One of my favorites is a Bill Murray line from the movie Meatballs. Although it’s part of a much longer rant, the key phrase is, “It just doesn’t matter!” That’s what I want you to remember from the study that examined the percentage of energy nutrients in the paleo diet. They found a significant difference in the range of nutrients, but the ranges are wide enough to incorporate the ketogenic diet as well as the Mediterranean diet.

Looking at the diets of hunter-gatherers in different parts of the world showed that the types of carbohydrates were dependent on what was available. In some cultures, digging up root vegetables and tubers was critical to the diet. But eventually, we learned to grow and process grains, and now we have an abundance of refined carbohydrates such as breads and pasta, often to our detriment.

What are the lessons?

Personalization

In one of the many commentaries I read on the merits and downfalls of the paleo diet, one researcher said this:

Ultimately, the best way to eat for your health is the change you can keep up with. Most people know what they need to do: limit calories, eat fruits, vegetables, whole grains, and lean proteins. The challenge is how to do it. There are lots of ways people can achieve this. The key is figuring out which is best for you as an individual that you can keep up with.

That uses a whole lot more words, but the message is the same as always: eat better.

When It Comes to Weight, It’s All About the Calories

Whichever way you decide to eat—and there are many ways to eat a healthy diet—losing weight is always going to be about how many calories you eat versus how many calories you expend. You can eat the carnivore diet, which is essentially all meat, although I wouldn’t recommend it. Or you can become a vegan. You can follow the DASH diet that I talked about a couple weeks ago, or you can eat the paleo diet. It just doesn’t matter. As long as you control the number of calories you eat, you can get to and maintain a normal body weight.

I believe you have to have vegetables and fruit as the foundation of your diet, but there’s a difference between maintaining a normal body weight and sustaining a healthy lifestyle. What we eat does matter. But quality aside, as always, it is and it will always be about the calories. Nothing else matters in controlling what you weigh. Eat less.

And if you can, eat better.

Summer Body Prep Time

/in /by

This week culminates with the first outdoor holiday of the summer season, and for many of us, the first family cook-out in over a year. Next week I’m going to review a study on the benefits of intermittent fasting, but I want to challenge you to mimic part of the study before the weekend to see how you do. Here’s the task.

For any two consecutive days, cap your eating at 1,200 calories. If you can get by on 1,000 calories, great, but no more than 1,200 and no fewer than 800. The second part is to make them vegan days as well. Don’t think only salads and carrot sticks: beans, legumes, nuts, root vegetables, and every other vegetable and fruit you can think of as well as whole grains. Two days—that’s all. Then you can resume your normal eating if you want. That will give you at least part of experience of the subjects in the intermittent fasting study I’ll review.

The irises in the photo are from our yard. Two years ago, we dug up entire iris beds and replanted them until we ran out of space. This year, they produced more flowers than ever, and they’re just beginning; the ones pictured are hand-me-down yellow ones we got from Paula’s dad and another called “Red at Night.” There are more colors to come, including an electric blue called “Blue Suede Shoes.”

All those flowers don’t happen by accident; neither does a healthier and fitter body. It takes work and it may take a while to see the benefits, just like the irises. Take the vegan-fast challenge and see how you do. Just remember: no lower than 800 calories and no more than 1,200. It will give you a sense of how the subjects initially felt in the study on fasting, the microbiome, and blood pressure.

Paula and I are going to spend this week putting flowers in containers, so this is the only Memo this week. Enjoy the outdoors and if you’re traveling, be safe. See you next week.

The Bottom Line on Meatless Burgers

/in /by

There are a couple more differences between the meatless burgers and beef burgers. To get the red color, the Impossible Burger uses soy leghemoglobin from the roots of soy plants, while the Beyond Burger uses beet juice. Both are vegan and give the burgers their red color. The Impossible Burger also adds some B vitamins and minerals. The Beyond Burger seems to add only some iron.

Are the meatless burgers healthy or not? From a strict look at fat content, no. Cholesterol level, yes. Sodium content, no, depending on how much salt you add to your beef burger; if you add more than one-sixth teaspoon of salt to your burger, you’ve lost that advantage. In effect, they’re very comparable to 80-20 burgers you would cook.

The real difference is that the meatless burgers are sourced from vegetable protein. Even that may strike up a debate because one uses soy protein while the other uses pea protein. Some people try to avoid soy, although there’s no real reason for it with the exception of being allergic to soy. (Check The Bottom Line on Soy Protein in the Store).

The other difference is that they both have carbohydrates and fiber because they’re sourced from plants. While there’s not a lot of fiber, that’s an advantage over beef.

The critical factor is how the burgers are prepared and presented. The final fat count will depend on how long the burgers are cooked: the longer any burger cooks, the more fat it loses to the grill. The presentation also matters. Buns, mayonnaise, cheese (for vegetarians who eat dairy), ketchup, and other condiments can take a 250 calorie burger and explode it to 700 calories or more.

There’s no information available about the environmental effects of meatless burgers, but usually vegan foods are environmentally friendlier than animal products even with the shipping and processing necessary for faux foods.

Beyond Patties

You can find Beyond Meat burger patties in some grocery stores in addition to their brand of plant-based bratwurst sausage, Italian sausage, and meat crumbles. Would your chili or meatloaf taste different with faux beef? We’ve tried cooking with other brands of vegan “beef” and noticed only a lack of fat, although if we use beef, we usually rinse it after browning it to remove most of the fat. The lower cholesterol in the meatless beef would be a big nutritional plus, but of course all this scientifically created food comes at a price: expect to pay two or three times as much as for plain old ground beef.

The Bottom Line

On paper, the meatless burgers could potentially be healthier than beef burgers. Whether they’re healthy or not is a different story. I haven’t seen research on how the meatless burgers respond to flames and whether they may produce undesirable chemicals. On top of that, the presentation mentioned earlier also matters.

Most likely whether they’re successful or not depends on the taste. I haven’t tasted either yet but I’ve planned a tasting barbecue soon, and I’ll let you know what I find out. Until then, it’s beef burgers for me. It would be exciting to have a plant-based burger that meets the taste test. Let me know how you feel if you try them.

Defining Healthier Burgers

/in /by

Other than being plant-based, how do these burgers compare for being healthy? In order to know that, we must define “healthy.” Beef is criticized, no matter how it’s raised and processed, for having too much unhealthy fat. How about the Impossible and Beyond Meat burgers?

A burger generally uses 80/20 beef, which means 80% protein to 20% fat by weight. That isn’t how it turns out in calories. A typical four-ounce beef patty has 280 calories with 20 grams of protein and 22 grams of fat. There’s also 80 mg of cholesterol.

Both faux burgers offer 20 grams of protein, but then the differences begin. The Impossible Burger has 14 grams of fat in a four-ounce burger with no cholesterol. The Beyond Burger has 18 grams of fat and no cholesterol. There’s a little less fat in the vegan burgers, but it’s fat that makes a burger a burger so they’re about tied.

One difference is in sodium levels. Beef does not have sodium added, so it starts with about 80 mg of sodium while the vegan burgers come in with close to 400 mg of sodium each—but you know you’re going to salt that burger before you eat it, so to be fair, you need to factor in whatever salt you add. What I don’t know is whether the sodium is critical to the vegan burgers or not. Because it’s a manufactured product, does the sodium have to be there as a preservative or something to that effect? Could they be manufactured with less sodium without sacrificing taste?

I’ll finish this up this weekend so you can get the menu set for the 4th of July.

Are You Ready for Meatless Burgers?

/in /by

Grilling season is here and that means all kinds of meat get char-broiled. I love a good burger, but that leaves a growing segment of the population out of luck: vegans and vegetarians. Grilled vegetables are great, from asparagus to zucchini, but some people love the sensation of chowing down on a burger. They miss out.

There are veggie burgers out there. I’ve had Boca Burgers and black bean burgers as well. They may be shaped like a burger, but the taste often leaves me feeling cheated. That may not be the case any more with two new additions: the Impossible Burger and the Beyond Meat Burger. Even before I could dig into the background of each, there have been a number of articles questioning whether these burgers are actually healthier than regular burgers. That’s what we’ll focus on this week: what’s in these burgers and whether they’re healthier than a regular burger.

In checking the labels, one difference is the protein source. The Impossible uses soy-based proteins while the Beyond uses pea protein. One thing to note is that they’re both proteins because they have all the necessary amino acids or can make them from the essential amino acids contained within. I’ll get into the rest of the ingredients on Thursday to check whether they’re healthier than beef burgers.

The Bottom Line on “What the Health”

/in /by

“What the hell is going on around here?” That’s one of my favorite sideline videos of Vince Lombardi as he’s talking to his players, and that’s the way I felt after watching this movie. As I said, I’m going to cover one of the studies that was cited several times, but there’s a whole lot more science that warrants explanation; it’s available for Members and Insiders as a Straight Talk on Health audio. Now to the study.
 

“A Vegan Diet Is Better Than ADA Diet”

One of the films experts may be recognizable to some readers: Dr. Neal Barnard, president of the Physicians Committee for Responsible Medicine. He’s a leading proponent of a vegan diet. He led a research group that conducted a study to compare a vegan diet with a diet based on the American Diabetes Association diet guidelines (2). In the film, there were several references to the study that claimed it was more effective than the ADA diet—in fact, twice as powerful at controlling or reversing diabetes as the ADA diet, which included meat and dairy.

Researchers gave both groups dietary guidelines to follow for each diet as well as training with a registered dietician; 49 subjects began in the vegan group while 50 began in the ADA group. The study went 22 weeks and then continued through 74 weeks with the subjects tested periodically. I don’t know the significance of the 22 weeks; those results were not included in the paper.

Here are the results that didn’t quite make the movie:

  • There were no differences in the decrease in blood sugar; both diets reduced fasting blood sugar a similar amount.
  • Fewer than half the people in both groups completed the study.
  • The subjects in both groups claimed to reduce their caloric intake over 400 calories per day. However, weight loss was just ten pounds in the vegan groups and seven pounds in the ADA group. Really? In 74 weeks? Those results are simply not possible unless the subjects did not accurately report what they ate.
  • Finally, this study didn’t show that a vegan diet was twice as beneficial as the ADA diet; it showed that they were both ineffective at achieving reasonable goals for weight loss and a reduction in HbA1c over an extended period of time. While it was statistically significant, a reduction from 8.1% to 7.7% in over a year is not much improvement. Yes, it was better than the ADA diet in which the HbA1c stayed the same, but I wouldn’t start touting the benefits for diabetics just yet.

 

What the Movie Did Right

The only expert who comes through this movie unscathed is Dr. Caldwell Essylstein, the physician from the Cleveland Clinic who has demonstrated in a large clinical trial that severe CVD can be reversed using a low-fat vegan diet. I’m a fan of his work and education program. He was in only a couple of scenes and did not corrupt science in anything he said.

No so for many others in the movie. I just don’t understand why these medical and healthcare professionals would say the things they said. I have more to say, and it’s in the Straight Talk on Health audio for Members and Insiders.

What the movie got right was to provide the research that the experts cited in the movie. It was done scene by scene and makes it easy for anyone to check where the experts got their research facts. Unfortunately, that didn’t stop the research from being misinterpreted by people who know better.
 

The Bottom Line

“What the Health” is a mess of a documentary. It’s not an objective examination of what constitutes a healthy diet; it’s a critique of the food industry and health organizations that get funding from that industry. The problem is that it’s not done very well and never quite gets around to proving what it claims. Maybe they’ll do better next time.

I know a vegan diet is a very healthy way to eat if you do it right. We must move to a more plant-based diet if we’re going to be healthy, and it’s better for the planet as well. While I don’t think it’s the only healthy diet, it’s certainly great if you take the time to learn how to follow it correctly. The problem is that the plants we count on for nutrients may continue to have fewer of them. That’s the topic for next weeks Memos.

“What the Health”: False Sugar Claims

/in /by

“Sugar doesn’t cause diabetes!” So says just about every expert in the film “What the Health.” Of all the misstatements in the film, this one is the worst and most dangerous. It isn’t because the statement is false; it’s because of the way it’s presented. Expert after expert looks into the camera and says that excess sugar intake does not cause type 2 diabetes. On top of that, the explanations that they give to justify their position are misleading.

One expert said that sugar will be stored as glycogen in the liver and the muscles and the rest used for energy. That’s correct. Another talked about the Duke University Diet which included rice, sugar, and some fruit and fruit juices; one physician used it to help many people who were too sick for other treatments. All the experts filmed agreed that neither sugar nor carbohydrate caused type 2 diabetes. It just couldn’t.

They are stopping short of telling the truth or intentionally misleading the audience. Sugar doesn’t cause type 2 diabetes if the person does not overeat. The statement about glycogen? True, as I said, but when a person overeats carbohydrates, the liver stores as much glycogen as it can and then converts the rest to fat.

Excess carbohydrates lead to insulin resistance and eventually, type 2 diabetes. The Duke University Diet? That was from the 1940s. It was an ultra low-fat diet with no salt, and was used to treat the sickest patients but only under the care of a physician.

The section on sugar and diabetes was by far the worst. It intentionally misleads people to think that overeating is fine as long as it’s carbohydrates. But there was one study that was cited over and over that’s even worse in my opinion. I’ll cover that on Saturday.

“What the Health”: Half a Star

/in /by

“What the Health” claims to be “the health film that health organizations don’t want you to see.” My opinion: it’s a movie that isn’t worth the time it takes to see it, and I’d rate it at half a star. The movie is directed by Kip Anderson, the narrator and star of the movie, and Keeghan Kune; it’s supposed to be about Andersen’s journey to health. It’s more like a movie to nowhere due to a lack of skill in directing and research.

The obvious thing a movie is supposed to do is to tell a story; this one doesn’t. We don’t really get to understand why Andersen begins his quest. He wasn’t sick. He wasn’t overweight. He was already exercising. Why did he want to begin this journey? What we see are his questions about a healthy diet and the answers he gets from experts that explain why a vegan diet is the only healthy diet.

Those health organizations he’s talking about are the American Diabetes Association, the American Cancer Society, and just about every other national health association. He reviews their websites, sees that they recommend diets that are other than vegan, and thus he deems them unhealthy. Then he tries to interview dietary experts from the organization about why the organizations advocate these unhealthy diets. Alas, no one wanted to talk with him. The theme of the movie is that every organization takes money from meat, dairy, and refined food producers; therefore the organizations are corrupt because they don’t advocate a vegan diet.

The direction and writing are poor, but the real problem is the science that the film’s experts try to sell us. I’ll cover two primary issues in the next two Memos, but I don’t have the space to give a complete evaluation of all the claims made in this film. If you want to know more, I’m recording a Straight Talk on Health for Members and Insiders that will be posted later this week.

The Ignorant Vegan

/in /by

Before you write me an indignant email, remember this: the definition of ignorant is lacking awareness or uneducated. While being a vegan is a great way to eat, it can also be done poorly and thus can create health issues over time if vegans haven’t bothered to educate themselves. The issue is the foods people choose to include in their vegan diet.

Start with white: pasta, rice, bread, potatoes. Those are all vegan choices and can be prepared with some excellent recipes. The problem is the same as it would be for anyone, vegan or not: too many starches lead to an exaggerated insulin response. Calories still count: those extra calories can be converted to fat and actually increase cholesterol levels. You don’t get to overeat just because you’re vegan.

 

Nutrient Deficiencies

The problem doesn’t end there. Focusing on starches can limit the amino acids necessary to make complete proteins, at least in enough quantities to keep the body healthy. Isoleucine, leucine, and lysine are all deficient in those white starchy foods. The white foods have to be balanced with legumes which have high amounts of those amino acids.

Another potential issue can be iron. Because vegans do not eat seafood or meat, they can become iron deficient over time—and I’m talking six months or more. Yes, green vegetables such as spinach and kale do have iron, but a person has to be diligent in knowing the sources so they get those vegetables every day or at least several times per weak. In addition, soy products, sometimes a staple of a vegan diet, can interfere with iron absorption.

Last is vitamin B12. It’s sparse in plant-based products so unless you eat brewer’s yeast or the English staple marmite, vegans must take a B12 supplement.

 

Learning to Be a Vegan

Being a vegan is a healthy approach to improving your health but you have to be informed. It takes work for a while, until it becomes second nature. The one thing you can’t afford to be is an ignorant vegan. It can be dangerous to your health—the last thing you want.

Next week, I’m going to review the movie “What the Health” so make sure you see it this weekend. We’re going to answer the one question posed by the movie: does the science show that a vegan diet is the only path to optimal health?

What Do Vegans Eat?

/in /by

The simplest way to describe a vegan diet is that it includes everything—except any food that comes from animals. If it comes from a plant, you can eat it. That includes all vegetables, all fruits, all grains, all legumes, and all nuts.

Peanut butter and jelly? Yes, if the bread is vegan. Baked sweet potato with brown sugar? Yep. A glass of wine or beer? Absolutely. Vegan pasta with marinara sauce? Ditto, but don’t add the Parmesan. I could go on and on, but you can see that it’s more than just salads and raw vegetables. And yes, you should eat plenty of those as well.

What should you eliminate? Meat from any animal; fish is also off limits. Fat from any animal. Anything cooked in or containing animal fats. Those biscuits you love? They’re made with lard, which comes from beef. The butter that goes on those biscuits? Nope, it comes from milk. Your favorite cake? No, it’s made with eggs. How about Jell-O; certainly Jell-O has to be okay! Not that either. It contains gelatin which comes from an animal. You can still eat those deep-fried foods as long as the oil is all vegetable.

The animal sourcing can extend to supplements as well. Gelcaps and capsules are made from animal or fish gelatin, although there are good vegan choices today. But don’t skip the supplements; they’re important because one nutrient that’s not easily accessible from plants is vitamin B12.

Just as there are vegan supplements, there are vegan versions of almost any food you can think of: eggs, milk, cheese, bread, burgers, even steak. I don’t know how good they taste, but they exist.

Seems pretty straightforward, doesn’t it? I’ll tell you how people can get it wrong on Saturday. Don’t forget to catch the documentary “What the Health” so you can follow along my review of the movie next week.

What are you prepared to do today?
