Eating a Ton of Vegetables Isn't a Good Idea

I love vegetables. There are so many foods that I can't eat that meals would be boring without them. In fact, I like them so much that I planted five kinds of lettuce and two kinds of tomatoes in my garden today. All the same, stuffing yourself with vegetables (or anything else) isn't good.

1. Fibrous vegetables can drive up your blood sugar if you eat enough of them. In one of his books, Dr. Richard Bernstein discussed a patient who ended up with a very high blood sugar after eating a head of lettuce. There are stretch receptors in your intestines that, when they sense you've eaten a big meal, release hormones that can end up raising your blood sugar. Bernstein calls this the Chinese Restaurant Effect.

2. All food is inflammatory. As Michael Eades put it,
Eating is an inflammatory process. A number of scientific studies have shown that eating a meal, regardless of the macronutrient composition, causes acute inflammation, which makes sense when you think about it. Food coming into the body is a foreign substance that fires up the innate immune system – but it does so briefly until the food is digested and the various fats, proteins and carbohydrates are broken down into their basic units and absorbed into the blood stream. (Although it might seem strange that food that we absolutely need to live could cause inflammatory problems, it makes sense when you realize that the very oxygen we breathe and that we would be dead in about four minutes without is slowly killing us also.) 

Caloric restriction is no fun, but is it worth it to stuff yourself with inflammatory brussels sprouts?

3. Certain vegetables can upset your stomach. Contrary to conventional wisdom, if you're in distress after eating certain vegetables (broccoli, cabbage and cauliflower and best known for this), the answer isn't to adapt to it, unless you're punishing yourself or the person who has to smell your gas. The answer is to eat less of them, or in some cases give them up. Given our digestive system is more like that of a carnivore than an herbivore, it's natural that some people have limited tolerance for vegetables and surprising that some people can eat so much of them.

4. Fibrous vegetables are calorie-poor. People have been so focused on cutting calories for so long that this might seem like a good thing. But many people have described problems on low-carb diets such as low energy, poor mood, hair loss and feeling cold--all things that are symptoms of low-calorie diets. Many report the symptoms go away when they add starch to their diet. You could also say they've added calories to their diet. This phenomenon seems to have come up at the same time that it became fashionable to gorge on fibrous vegetables. The low-carb diets of decades past called for a generous amount of fat, not fiber.

5. Finally, it's wasteful to gorge on anything. If you recycle your trash, compost your peelings, drive a Prius or take public transportation, eating pounds of vegetables every day (far in excess of what you need) doesn't make sense. Vegetables have to be irrigated, fertilized, sprayed for pests (even organic vegetables), and shipped to market. And they cost money! There's no need to give them up entirely, but there's no need to gorge on them, either.

I also want to add that the modern concept that your vegetables have to be as close to the raw state as possible adds to the problem of a vegetable digestion. It is especially true for the cruciferous veggies.

Agreed. Food in general is easier to digest when it's cooked.

I think Dr. Bernestein's "Chinese Restaurant Effect" is really illuminating and explains why a high-volume, low-calorie diet may not be in one's best interests. So people loading their plate with 80% plant matter and only 20% protein/fat may be doing their body a disservice.

Yes, when you consider that we have guts very similar to carnivores and not much like herbivores, some people are going to have significant problems on such a diet.

Winning! Read some good news!

The good news keeps on coming. After four years of the country being in the biggest mess that most of us have lived through, it feels like spring is here early.

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...

Let's Grow Vegetables from Seed

MAHA may be a great idea, but what you do at your house is more important for your health than what's happening at the White House. Growing your own vegetables provides food that's fresher and tastes better than store-bought and helps you get some fresh air, sunshine and exercise. If you grow enough, you can even can your own sauces and soups that don't have any franken-food ingredients. My first time growing celery from seed.  Here in central Indiana, it's time to plant celery from seed since the average last frost date is 10 weeks away. In a few weeks, it'll be time to plant tomatoes. There are a couple of ways to figure out when to start various seeds where you live: You can find out when it's time to plant things by 1) looking up your average last frost date, 2) getting a seed packet and looking at the instructions for starting the seeds indoors, and 3) counting backwards on a calendar by the number of weeks indicated. You could also ask Grok (X's AI fea...

Blog Lineup Change

Bye-bye, Fathead. I've enjoyed the blog, but can't endorse the high-fat, high-carb Perfect Health Diet that somehow makes so much sense to some otherwise bright people. An astrophysicist makes some rookie mistakes on a LC diet, misdiagnoses them, makes up "glucose deficiency," and creates a diet that's been shown in intervention studies to increase small LDL, which can lead to heart disease. A computer programmer believes in the diet and doesn't seem eager to refute it because, perhaps, scientists are freakin' liars and while he's good at spotting logical inconsistencies, lacks some intermediate knowledge of human biology. To Tom's credit, he says it's not the right diet for everyone, but given the truckload of food that has to be prepared and eaten, impracticality of following it while traveling (or even not traveling), and unsuitability for FODMAPs sufferers, diabetics and anyone prone to heart disease (i.e., much of the population), I'm...

This Just In: Yogurt Doesn't Improve Health

A recent study from Spain finds "In comparison with people that did not eat yogurt, those who ate this dairy product regularly did not display any significant improvement in their score on the physical component of quality of life, and although there was a slight improvement mentally, this was not statistically significant," states López-García. Most yogurt is pretty much pudding with a little bacteria . Pudding is a sugar bomb. Hard to believe the stuff doesn't improve health outcomes, isn't it? But as usual, researchers are calling for...more research. "For future research more specific instruments must be used which may increase the probability of finding a potential benefit of this food."
