Glucose vs Fatty Acids, which one makes you fat?

Thursday, October 6, 2016

Fatty acids, which derive from the saturated fat that we eat, are never stored as adipose tissue in the body. Thus, they do not make you fat; glucose does. Fatty acids are first broken down into ketone bodies (aceto-acetate, beta-hydroxybutyrate, and acetona) before being used by the mitochondria in the Krebs cycle. The primitive hunter's cellular mitochondria used ketone bodies (fatty acids) as cells' fuel instead of glucose because he simply did not eat carbohydrates-containing food, for agriculture had not been developed yet. To sum up, excess glucose makes you fat, fatty acids never.

High levels of glucose make you fat because it induces the pancreas to pump up insulin into your blood stream. Insulin, in turn, makes your body tissues stores it as adipose tissue, that is to say, fat. That's how you become obese. Glucose is obtained from the starchy and sugar-containing foods we eat. Starch and sugar are called carbohydrates, which are broken down into glucose in the body by the pancreas enzymes. Thus, too much starchy and sugary foods means high levels of glucose in your blood stream, which are converted into bodily fat by insulin.

How Saturated Fat is Broken Down in the Body

Friday, September 30, 2016

The saturated fat that we eat is the most efficient food and form of energy for the human body. It is broken down by lipase (pancreatic enzyme) into glycerol and fatty acids, which is stored in the liver. This organ further breaks down fatty acids into ketones, like aceto-acetate, acetone and beta-hydroxybutyrate during famine or when we follow a ketogenic diet, which is the type of diet the primitive hunter used to have before agriculture, with 60% saturated fat, 30% meat protein, and 10% vegetable and nuts.

The nerve cells and muscle fibers of the prehistoric hunter (Neanderthal Man and Cro-Magnon) used beta-hydroxybutyrate as fuel, since there was not enough glucose level in the blood as there was not carbohydrate foods available. This ketone body is three times more efficient fuel than glucose, promoting the biogenesis of the mitochondria (the cell power plant) and this in turn can induce the neurogenesis of neurons.

Stress relief treatment

Aside from working out and spending time in quiet places in contact with nature, floating naked in a bath full of Epsom salt is a good therapy for stress relief.

Stellate Ganglion

Wednesday, April 6, 2016

The stellate ganglion is a sympathetic nerve ganglion located in the base of the neck, right behind the vertebral artery. Being part of the sympathetic ganglionic chain, it originates through the merging of the inferior cervical ganglion and the first thoracic ganglion, which are joined together by the loop of Vieussens. Although it is usually present in most individuals, others do not have this ganglion.

From the stellate ganglion comes off the inferior cardiac nerve, which is a sympathetic nerve that works as a heart rate accelerator, being part of the cardiac plexus.

Blue Origin Reusable Rocket Makes Vertical Landing

Monday, April 4, 2016

The Blue Origin's reusable rocket made its third successful vertical landing. This rocket uses a BE-3 liquid-pump-fed engine. Compared to the Atlas and Saturn's expendable boosters, the new rocket of Blue Origin is reusable and will make flying into space and putting satellite in orbit much less expensive.

Mesenteric ganglion

Friday, March 11, 2016

The mesenteric ganglia are two groups of nerve cells that belong to the chain of prevertebral ganglia of the sympathetic nervous system, innervating the gastrointestinal organs. The human being has two mesenteric ganglia:

1) The superior mesenteric ganglion, which is located on the anterior surface of the abdominal aorta, at the point of origin of the superior mesenteric artery; its nerve fibers runs along this blood vessel and  innervates the small intestine.

2) The inferior mesenteric ganglion is also found on the anterior side of the abdominal aorta but adjacent to the point where the inferior mesenteric artery arises. It supplies and innervates the large intestine and the bladder.
