Dr. Michael Miller, a heart doctor and professor, recently answered some questions about heart disease as it relates to metabolic dysfunction. Metabolism has to do with how the body breaks things down and processes them. Certain tests can tell us if the body is having difficulty with those activities, because if it is, health problems could follow.
The article with Dr. Millers suggestions is published in the Nutrition Action News Letter July/August 2012 issue. Within that piece, is a reference to a study that showed the increased risk of both heart disease/attack and diabetes incidence with each factor of metabolic dysfunction that a person has. The figure from the article was originally published in the AHA journal Circulation. You can access the article here, for free. I include the figure below, as it is one of the best representations I have seen.
First let me explain what factors make up the Metabolic Syndrome while noting that the importance of each one is the subject of debate amongst professionals/scientists. The 5 factors that were the focus of both the AHA and Dr. Miller articles are:
- Blood pressure equal to or higher than 130/85 mmHg
- Fasting blood sugar (glucose) equal to or higher than 100 mg/dL
- Large waist circumference (length around the waist):
- Men - 40 inches or more
- Women - 35 inches or more
- Low HDL cholesterol:
- Men - under 40 mg/dL
- Women - under 50 mg/dL
- Triglycerides equal to or higher than 150 mg/dL
Dr. Miller has some quote worthy comments for you to consider, they include:
When the gut is the first thing you see when a patient walks in the door, that is not a good sign
....a lot of men have disturbed metabolism before they reach 40 inches (WC).
Even too much of the right foods can be a problem.
He also spoke to the issue of getting your TG levels from a health fair, which usually does not include a fasting level. He said that he has heard of people having a TG level of 400 and being told not to worry about it because it was not a fasting level. He contends that someone should very much be worried about that level because even immediately after an "unhealthy" meal the TG levels do not rise more than 50% - though they may, in rare instances, double. So if ones non-fasting TG level is 400, then their fasting level could be 200 and that is TOO high.People shouldn't douse their salad with olive oil or they might get too many calories. (in response to a question about healthy oils - douse means use a lot!)
The good news is that TG are directly and substantially reduced through exercise and meal patterns. Exercise causes the body to release an enzyme that breaks down TGs. Also, limiting sugar and saturated and trans fats is important. Dr. Miller recommends very little added sugar - 24 g a day. He enthusiastically recommends fish oil - but in fish not capsules. There is more but you get the idea.
Below is the chart I mentioned earlier. Notice how much higher the risk for adverse health outcomes is when a person has 4 or 5 of the risk factors. The figure is more readable if you go to the article.
