MineFit TidBit: The Fatal Flaw of the Low Fat Diet

Posted By Darrell Smith, Friday, June 24, 2016
The MineFit Q2 Initiative highlighted some of the most important determinants for a successful day of Focus and Attention as they relate to (1) job performance on the worksite; (2) fitness and nutrition, and (3) relevant aspects of feeling good when arriving and departing from work.  

This Friday Tidbit piggy-backs on our Monday Move by giving you the “why” behind healthy vending machine choices. 

It has been known for decades that low-fat, high-carbohydrate diets can increase plasma triglyceride levels, and it has been suspected that diets lower in carbohydrate and higher in fat and protein are beneficial to health. Translation: When you pick the pretzels or the fruit snacks instead of the chips and the trail-mix from the vending machine, you are raising your BAD cholesterol levels and contributing to health problems. Additionally, you are negatively affecting your ability to sustain energy, focus, and attention at work. 
A recent study from the NBCI used new isotopic and nonisotopic methods to determine in vivo whether low-fat, high-carbohydrate diets increase triglyceride levels by stimulating fatty acid synthesis. The results of a series of studies in lean and obese weight-stable volunteers showed that very-low-fat (10%), high-carbohydrate diets enriched in simple sugars increased the fraction of newly synthesized fatty acids, along with a proportionate increase in the concentration of plasma triglyceride. 

Furthermore, the concentration of the saturated fatty acid, palmitate, increased and the concentration of the essential polyunsaturated fatty acid, linoleate, decreased in triglyceride and VLDL triglyceride. The magnitude of the increase in triglyceride varied considerably among subjects, was unrelated to sex, body mass index, or insulin levels, and was higher when fatty acid synthesis was constantly elevated rather than having a diurnal variation. It was notable that minimal stimulation of fatty acid synthesis occurred with higher fat diets (>30%) or with 10% fat diets enriched in complex carbohydrate. Translation: A low-fat diet showed increased levels of negative cholesterol AND decreased levels of essential fats to fight bad cholesterol levels. Moreover, the effect was consistent regardless of age and gender.  

...Big News in a Small TidBit. Have a good weekend, and please share this with your plant managers, heads of health and safety, and HR departments. And remember, you are the model and the example of MineFit. Thank you, Monica Pampell, Head Coach, MineFit.

-Notice that the “Right Choice” labeled in the green strip to the right of the machine is often the low-fat choice, and thus the poor choice.
