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.

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."

Paleo Diet: Eating Differently from Everyone Else is Fine!

I've been seeing more and more articles by women (it's always women) whose heads have exploded trying to figure out life without yogurt and cupcakes. Oh, the shenanigans they get up to: bathroom problems from stuffing themselves with vegetables, paleo baked goods that don't taste the same as ones from the bakery, and especially the irresistible urge to eat "normally." The technical problems aren't hard to sort out: substitutes like baked goods will taste different because they are different, but an adjustment period of a few months will make those foods taste normal. And whatever you eat, don't stuff yourself. First, though, read a book by Loren Cordain or Mark Sisson to learn about the paleo diet before diving in. The articles I keep reading, though, have more to do with attitude: the urge to be exactly like everybody else or the urge to be helpless. If you're in the second category, I can't, by definition, help you. If you'd rather be Lu

Decongestant Ineffective; Vibration Plate Works

A common ingredient in many cold medicines has been shown so ineffective that the FDA recently proposed taking it off the market. The ingredient, phenylephrine, "failed to outperform placebo pills in patients with cold and allergy congestion," say researchers from the University of Florida. "The same researchers also challenged the drug's effectiveness in 2007, but the FDA allowed the products to remain on the market pending additional research," according to CNBC .  Mostly placebos. Photo from Pixabay . I can attest that phenylephrine doesn't work. Before I stopped eating wheat, I constantly had nasal and sinus congestion. I helped keep Sudafed in business when the active ingredient was pseudoephedrine, but I noticed the PE (phenylephrine) variety didn't work at all. The only other decongestants I've found helpful are guaifenesin (Mucinex) and spicy food. Mucinex is expensive because it works! (The cheaper store brands work just as well, though.) Su

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 .
