The US Government is Reversing Its Long-Standing Guidelines Concerning Cholesterol Guidelines
The U.S. Dietary Guidelines and Advisory Committee DGAC stated in March, 2015: “Available evidence shows no appreciable relationship between consumption of dietary cholesterol and serum cholesterol.”
Therefore, the old DGAC Guidelines previously stating the total daily intake of dietary cholesterol should be less than 300 mg/day, will be removed.
The recommendation to consume less than 30% of your daily caloric intake in fat is expected to remain the same.
The previous DGAC recommendations were based on the heart-diet hypothesis. The heart-diet hypothesis proposes that the increased intake of cholesterol and saturated fat, increases blood cholesterol levels, which leads to hypercholesterolemia, which in turn supposedly leads to heart disease. This hypothesis is under scrutiny.
There is conflicting research on whether high blood serum cholesterol levels have any impact on heart disease or more specifically Coronary Heart Disease, CAD, where the blood vessels and arteries can become clogged, leading to angina and potentially deadly cardiac events.
In previous articles on this subject, you will find reporting from the Journal of Cardiac Medicine – Circulations, “reporting that your time in the One-Mile-Walk-Jog-Run Test, is the most accurate predictor of your chance of dying of a cardiac event.” The report went on to say that if you can complete this test in 8 minutes or less, you have a very low chance of dying of a cardiac event. The longer it takes to complete a One-Mile, the more risk you have of dying of a cardiac event.
You, the personal trainer can be the number one factor to improving your clients’ longevity by incorporating an exercise prescription to improve your clients’ cardiovascular health using GPO (Gradual Progressive Overload) to get your clients’ One-Mile Time under 8 minutes. The World-Record for the One-Mile-Run is under five minutes for 60 years old and over.
For your clients’ with hypercholesterolemia that are on Statin drugs prescribed by their Doctor…You CANNOT advise them to stop taking their medications. This is practicing “medicine without a license” and illegal. But you should have an educational conversation with them recommending they discuss this research with their Doctor. They also need to do their own research via legitimate sources of trust-worthy information.
Some Key Points to Keep in Mind:
- Ancel Keys, who many consider to be the “Father of the Heart-Diet Hypothesis,” stated “there is no connection between cholesterol in food and in the blood. And we have known this all along. Cholesterol in the diet does not matter at all, unless you happen to be a chicken or rabbit.”
Note: This is a well-known physiological fact, since the liver produces the majority of cholesterol in the body. The liver also “regulates” cholesterol production, increasing production when dietary intake is low and decreasing production when dietary intake is high.
- Recent research suggests cholesterol is NOT a cause of heart disease.
Note: Most researchers now believe the primary cause of heart disease is inflammation and oxidative stress. Evidence: Women have HIGHER cholesterol levels than men, yet suffer from 300% less heart disease than men.
Australian Aboriginals have the LOWEST cholesterol levels in the world, yet have the HIGHEST rate of heart disease.
Europeans, on the other hand, have the HIGHEST cholesterol levels in the world, however, have the LOWEST rates of heart disease!
You may have already noticed in some cases with your Personal Training Clients, they have lost weight and are in much better shape, but their cholesterol numbers have not improved to match their health and fitness improvements. Now you know not to worry about it.
What we do know is the far more important risk factors for heart disease are: exercise, smoking, obesity, hypertension, diabetes and stress.
As an IFPA Personal Trainer & Fitness Professional, focus on what you can do to help people live healthier, happier and fitter lives!
