Should your Teeth and Heart Follow Two Different Diets?

There's a lot of conflicting dietary advice around, but conventional wisdom contradicts itself on diet for a healthy heart v. diet for healthy teeth. The commonly recommended heart-healthy diet is low-fat, little meat, lots of whole grains, and fruits and vegetables. That doesn't quite square with "Foods and Drinks Best for Your Teeth" from that pillar of medical dogma, WebMD.com:

The best food choices for the health of your mouth include cheeses, chicken or other meats, nuts, and milk. These foods are thought to protect tooth enamel by providing the calcium and phosphorus needed to remineralize teeth (a natural process by which minerals are redeposited in tooth enamel after being removed by acids).

Other food choices include firm/crunchy fruits (for example, apples and pears) and vegetables. These foods have a high water content, which dilutes the effects of the sugars they contain, and stimulate the flow of saliva (which helps protect against decay by washing away food particles and buffering acid). Acidic foods, such as citrus fruits, tomatoes, and lemons, should be eaten as part of a larger meal to minimize the acid from them.

Take away the apples, pears and milk, or limit them greatly, and you have a low-carb diet. They add,

The more often you eat and snack, the more frequently you are exposing your teeth to the cycle of decay.

What--no little meals throughout the day? Well, if you're eating just chicken, other meat, cheese, nuts, and crunchy vegetables (i.e., no potatoes), you probably won't need to constantly snack because with little starch and sugar, you shouldn't have roller coaster blood sugar levels and frequent appetite throughout the day. Further,

Poor food choices include candy -- such as lollipops, hard candies, and mints -- cookies, cakes, pies, breads, muffins, potato chips, pretzels, french fries, bananas, raisins, and other dried fruits. These foods contain large amounts of sugar and/or can stick to teeth, providing a fuel source for bacteria.

So those heart-healthy whole grains aren't so good for your teeth. For benefit of those who don't cook, starch is sticky. Fat isn't. Fatty food (without starch or sugar) doesn't even get stuck in your braces. But starch (which turns into glucose on digestion) not only sticks to your teeth and braces, it sticks to certain proteins in your body in a process called glycation (see AGE or advanced glycation end products). In laymen's terms, it gums up the works of different cells and eventually causes serious health problems including heart disease.

Starch and sugar provide a fuel source for bacteria not only in your mouth, but throughout your body. There's a school of thought that infection contributes to or causes heart disease.

Conventional wisdom tells us that whole grains and a starch-based diet are good for your heart, but bad for your teeth. On the other hand, cheese is good for your teeth, but too fatty for your heart. There's low-fat cheese out there, along with a thousand other low-fat products, but have foods that are good for both hearts and teeth been around for only a few generations since someone created them in a lab?

Humans and our ancestors have had two and a half million years to adapt to a diet of mostly protein and fat  along with plenty of cholesterol, but with little starch and sugar. To be sure, we didn't evolve perfectly and our paleo ancestors didn't enjoy perfect health. But it's an extraordinary claim to say that the heart--an organ that has to work pretty much perfectly at all times--isn't adapted to the diet we evolved on, and yet our teeth are very well adapted to such a diet, even though you can get cavities or lose some teeth and, even without dental care, go on living. If anything, it seems to me that vital organs with no backup (the heart, brain, liver and pancreas) would be the best adapted to our evolutionary diet. That low-carb and ketogenic diets are so therapeutic for patients with heart disease, Alzheimer's disease, epilepsy and diabetes points in this direction.

Except in some special cases, there's no heart diet, GI diet, dental health diet, and so on. There are just good health diets.

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...

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 . ...

My Long-Term Experience Eating Safe (and Other) Starches

Years ago, before the Perfect Health Diet came out, I followed a program that involved eating quite a bit "safe starch." It was called Body for Life. It involved eating six small servings of carbohydrate along with six small servings of protein, plus two servings of fibrous vegetables per day. (A serving was the size of your fist or the palm of your hand.) There were six workouts a week (three weightlifting, three cardio) and one free day every week where you ate whatever you wanted and didn't exercise. In all fairness, these two programs are different: BFL allows certain grains, legumes and low-fat dairy and discourages fat. It doesn't call for a wheelbarrow full of vegetation. Nevertheless, my experience eating lots of fruit and lots of starch is relevant to the PHD because the amount and type of digestible carbohydrates are similar, and for the first few years, I didn't eat wheat except on free days. At first on BFL, I felt great. Before, I was continually...

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."
