Save Your Teeth and Live Longer

Diets bad for teeth are also bad for the body
Leila Gray

Dental disease may be a wake-up call that your diet is harming your body.

"The five-alarm fire bell of a tooth ache is difficult to ignore," says Dr. Philippe P. Hujoel, professor of dental public health sciences at the University of Washington School of Dentistry. Beyond the immediate distress, dental pain may portend future medical problems. It may be a warning that the high-glycemic diet that led to dental problems in the short term may, in the long term, lead to potentially serious chronic diseases.

Hujoel reviewed the relationships between diet, dental disease, and chronic systemic illness in a report published July 1 in The Journal of Dental Research. He weighed two contradictory viewpoints on the role of dietary carbohydrates in health and disease. The debate surrounds fermentable carbohydates: foods that turn into simple sugars in the mouth. Fermentable carbohydrates are not just sweets like cookies, doughnuts, cake and candy. They also include bananas and several tropical fruits, sticky fruits like raisins and other dried fruits, and starchy foods like potatoes, refined wheat flour, yams, rice, pasta, pretzels, bread, and corn.

One viewpoint is that certain fermentable carbohydrates are beneficial to general health and that the harmful dental consequences of such a diet should be managed by the tools found in the oral hygiene section of drugstores. A contrasting viewpoint suggests that fermentable carbohydrates are bad for both dental and general health, and that both dental and general health need to be maintained by restricting fermentable carbohydrates.

The differing perspectives on the perceived role of dietary carbohydrates have resulted in opposing approaches to dental disease prevention, Hujoel notes, and have prompted debates in interpreting the link between dental diseases and such systemic diseases as obesity, diabetes, and some forms of cancer.

Over the past twenty years or so, Hujoel says, people have been advised to make fermentable dietary carbohydrates the foundation of their diet. Fats were considered the evil food. A high-carbohydrate diet was assumed to prevent a number of systemic chronic diseases. Unfortunately, such a diet - allegedly good for systemic health - was bad for dental health. As a result, cavities or gingival bleeding from fermentable carbohydrates could be avoided only -- and not always successfully, as Hujoel points out -- by conscientious brushing, fluorides, and other types of dental preventive measures. When these measures are not successful, people end up with cavities and gum disease.

Hujoel observed that the dental harms of fermentable carbohydrates have been recognized by what looks like every major health organization. Even those fermentable carbohydrates assumed to be good for systemic health break down into simple sugars in the mouth and promote tooth decay. All fermentable carbohydrates have the potential to induce dental decay, Hujoel notes.

But what if fermentable carbohydrates are also bad for systemic health? Hujoel asks. What if dietary guidelines would start incorporating the slew of clinical trial results suggesting that a diet low in fermentable carbohydrates improves cardiovascular markers of disease and decreases body fat? Such a change in perspective on fermentable carbohydrates, and by extension, on people's diets, could have a significant impact on the dental profession, as a diet higher in fat and protein does not cause dental diseases, he notes. Dentists would no longer be pressed to recommend to patients diets that are bad for teeth or remain mum when it comes to dietary advice. Dentists often have been reluctant, Hujoel says, to challenge the prevailing thinking on nutrition. Advising patients to reduce the amount or frequency of fermentable carbohydrate consumption is difficult when official guidelines suggested the opposite.

The close correlation between the biological mechanisms that cause dental decay and the factors responsible for high average levels of glucose in the blood is intriguing. Hujoel explains that eating sugar or fermentable carbohydrates drops the acidity levels of dental plaque and is considered an initiating cause of dental decay.

"Eating these same foods, he says, is also associated with spikes in blood sugar levels. There is fascinating evidence that suggests that the higher the glycemic level of a food, the more it will drop the acidity of dental plaque, and the higher it will raise blood sugar. So, possibly, dental decay may really be a marker for the chronic high-glycemic diets that lead to both dental decay and chronic systemic diseases. This puts a whole new light on studies that have linked dental diseases to such diverse illnesses as Alzheimer's disease and pancreatic cancer."

The correlations between dental diseases and systemic disease, he adds, provide indirect support for those researchers who have suggested that Alzheimer's disease and pancreatic cancer are due to an abnormal blood glucose metabolism.

The hypotheses on dental diseases as a marker for the diseases of civilization were postulated back in the mid-20th century by two physicians: Thomas Cleave and John Yudkin. Tragically, their work, although supported by epidemiological evidence, became largely forgotten, Hujoel notes. This is unfortunate, he adds, because dental diseases really may be the most noticeable and rapid warning sign to an individual that something is going awry with his or her diet.

"Dental problems from poor dietary habits appear in a few weeks to a few years," Hujoel explains. "Dental improvement can be rapid when habits are corrected. For example, reducing sugar intake can often improve gingivitis scores (a measurement of gum disease) in a couple of weeks. Dental disease reveals very early on that eating habits are putting a person at risk for systemic disease. Since chronic medical disease takes decades to become severe enough to be detected in screening tests, dental diseases may provide plenty of lead-time to change harmful eating habits and thereby decrease the risk of developing the other diseases of civilization."

In planning a daily or weekly menu, Hujoel suggests: "What's good for your oral health looks increasingly likely to also benefit your overall health."

Fixing Your Aging Neck

The neck is quite often the tell tale sign of aging in humans. The robustness of a young athlete may be revealed in the full, strong, vibrant neck. On the opposite end of life, the weak, crooked, and wrinkled neck is often a sign that life on this planet is coming to a close. It's a very visual part of the human experience.
The cosmetic component is valid, but the health issue is even more valid. A strong neck will save your life in a fall, accident, or trauma. Weak, undermuscled necks are more susceptible to whiplash, knock out, or even muscle strains.
Too often the first action taken, when you are aware of how bad your neck looks is a sprint to the plastic surgeon's office. This is effective in terms of the visual aspect, but not so effective in the practical aspect. Good surgeons can clip muscles and tighten skin and change your visual age dramatically. They offer little in the way of strengthening the neck or making it more robust and functional. Only exercise can do that. Here are some simple guidelines that can make you younger in weeks, and possibly,..... save your neck.

First off, visit your doctor to determine if exercise is appropriate for you. He may know nothing about exercise and tell you only to do walking. Fire him as a doctor and get another one who trains and has an interest in health.

These exercises use only the weight of your skull initially, to stimulate muscle growth. Most everyone is SO weak in this area, that the skull will be a sufficient level of resistance.

Lay on a bed or better yet, and exercise bench, face down, with the head free to move through it's full range of motion. Your head should be hanging over the bed or bench. Simply raise the head up and down VERY slowly for 4 repetitions. Here is the interesting part. Each repetition will take ten seconds to raise, and ten seconds to lower. This slow speed of movement will keep soreness to a minimum, and safety at an optimum. When you are finished roll to your side and repeat. You may have to brace your lower arm on the floor to be stable and secure. Make sure to work both sides of the neck. Then roll on your back. Let your head hang free and slowly lift it, bringing your chin to your chest. The key of this exercise is very slow movement.

Repeat this drill three times each week for two weeks. Then it is time to add manual resistance in the form of your own palms pressing against your head. Resistance should be smooth and even, with the same 10 second cadence. All four sides of your neck should be trained evenly. One month of training will have you actually resisting fairly hard. From here, the next step is having a training partner, someone you trust, to apply resistance in all four directions. This is the highest level of training and is used by elite athletes, but can be scaled to any trainee at any fitness level.

This simple, safe, progression will change your appearance and give you a healthier, stronger, neck. The only frosting on the cake is to use ample sunscreen to prevent sun damage and cross linkage of the skin that covers those newly developed muscles. Forget about anti wrinkling creams, jams, jellies, and marmalades. The true anti aging skin cream is called sun screen and the only true anti aging neck process is call exercise.
