Reducing Heart Disease in Firefighters
Its been very well documented that the leading cause of firefighter-on-duty deaths is related to heart disease. Therefore any information regarding decreasing the chances of heart disease are very valuable to the firefighting community. I’ve recently been researching the correlation between cholesterol and heart disease and have found some interesting correlations.
The long-established dietary recommendations of yesterday have created epidemics of obesity and diabetes, the consequences of which dwarf any historical plague in terms of mortality, human suffering and dire economic consequences. Despite the fact that 25% of the population takes expensive statin medications and despite the fact we have reduced the fat content of our diets, more Americans will die this year of heart disease than ever before. Statistics from the American Heart Association show that 75 million Americans currently suffer from heart disease, 20 million have diabetes and 57 million have pre-diabetes. These disorders are affecting younger and younger people in greater numbers every year.
Many risk factors contribute to the development of heart disease, or atherosclerosis (hardening of the arteries). So what is the main culprit to the increasing numbers to this Heart Disease epidemic? Is it high cholesterol? About 50% of heart attacks and strokes occur in people with normal cholesterol levels. This suggests that many people at risk are presumably “healthy” because they have normal cholesterol levels.
What I’ve found is that there is a huge correlation between inflammation and heart disease. Did you know that inflammation in the arteries, not necessarily cholesterol, contributes to heart attacks and strokes?
What is inflammation? Inflammation is not complicated — it is quite simply your body’s natural defence to a foreign invader such as a bacteria, toxin or virus. The body can easily and efficiently handle acute cases of inflammation from bacterial and viral invaders. However, if we chronically expose the body to injury by toxins or foods the human body was never designed to process, a condition occurs called chronic inflammation. This chronic inflammation can then lead to major health issue including heart disease.
Take a moment to visualize rubbing a stiff brush repeatedly over soft skin until it becomes quite red and nearly bleeding. you kept this up several times a day, every day for five years. If you could tolerate this painful brushing, you would have a bleeding, swollen infected area that became worse with each repeated injury. This is a good way to visualize the inflammatory process that could be going on in your body right now.
Let me restate that, the recommended mainstream diet that is low in fat and high in polyunsaturated fats and carbohydrates, has been causing repeated injury to our blood vessels. This repeated injury creates chronic inflammation leading to heart disease, stroke, diabetes and obesity. So when you savor the tantalizing taste of a sweet roll, your body responds alarmingly as if a foreign invader arrived declaring war. Foods loaded with sugars and simple carbohydrates, or processed with omega-6 oils for long shelf life have been the mainstay of the American diet for six decades. These foods have been slowly poisoning everyone.
The proof is in the pudding, over the last 20 years the American diet has decreased its fat content, and replaced it with processed sugars and sweeteners yet the rates of obesity, heart disease and diabetes have sky-rocketed. Don’t believe me? Research for yourself (and let me know what you find out).
What can you do about it?
My research has shown that there are 3 things you can do immediately to help lower the inflammation in your body:
1. Stop smoking. Smoking causes inflammation in the body (due to the inhaled toxins) and hardens the arteries. Research shows you can reverse all of the damaging effects smoking causes within 5-10 years.
2. Change your diet. Minimize the processed foods in your diet, eat fruits, nuts and vegetables regularly. Researchers have shown that people who stick with a Mediterranean-style diet—based on fruits, vegetables, whole grains, nuts, and olive oil—can lower their levels of inflammation. This may not correlate with your current diet around the firehouse but we (as a firefighting community) need to change our culture. (Get eating and workout guidelines HERE. You can also decrease inflammation by reducing saturated fat and trans fats and eating more foods rich in alpha-linolenic acid—like flaxseed, walnuts, and canola oil—and omega-3 fats. Personally, my father has decreased his cholesterol, increased his energy and lost weight by adding a krill oil supplement. You can read about krill oil HERE.
3. Get active. Exercise is a great way to lower inflammation without any side effects associated with medications. Aim for five days a week, at least.
