CFD Nutrition Seminar ~ Part 1 of 6

On September 24th and 26th, Matt McKinney and Bill Santasiero gave a 90 minute seminar on Nutrition and how it affected you in and out of the box. Here’s part 1 of 6 of the series. I’m going to place some notes down after the video as a takeaway.

What does the body use for fuel?
• Glucose primary fuel source
• Complex carbohydrates are extended release versions of glucose
• Glucose is an essential nutrient, but can be created from protein/fat via gluconeogenesis.

Ketones
• When liver is depleted of glycogen it turns to fat for fuel.
• Ketones are created when fatty acids are broken down in the liver.
• Following a high fat/low carb diet a person’s brain get about 25% of its energy from ketones. After 3 weeks, that number increases to about 70% with the other 30% still from glucose.
• Ketogenic diets have seen success reducing issues with epilepsy, Alzheimer’s, and Parkinson’s to name a few.
• Increases GABA neurotransmitters and reduces glutamate neurotransmitters decreasing neuronal excitability and glutamate cytotoxicity.

Glucose vs Fructose
• Glucose preferred energy source not fructose
• They have different metabolic pathways.
• Fructose is only metabolized in the liver and is preferential to glycogen storage in the liver.
• Once the liver is full of glycogen, excess fructose is stored as fat.
• Fructose does not stimulate the production of leptin. Leptin is what tells your brain you’re full.
• If people continued to eat fructose only in fruit and occasionally honey as our ancestors did, the body would easily process it without any problems.
• Additionally, fructose is converted by the liver into glycerol, which can raise levels of triglycerides. High triglycerides are linked to increased risk of atherosclerosis and heart disease.
• Concentrated forms of fructose: agave, crystalline fructose, high-fructose corn syrup, to name a few

High fructose intake has been associated with:
• Increased levels of circulating blood lipids
• Obesity
• Fat around the middle
• Lowered HDL
• Increased levels of uric acid (associated with gout and heart disease)
• Liver scarring (cirrhosis)
• Fatty liver
• The formation of AGE’s* (advanced end glycation products), which can lead to wrinkling and other signs of skin aging
• *Some studies show that fructose creates AGE’s up to 10 times more efficiently than glucose
