Good Morning
Halloween is just around the corner, time to pull out your favorite costumes and put out the fall decor. Today’s topic seems especially pertinent with all the Halloween candy that is available everywhere you go.
Added sugar is the single worst ingredient in the modern diet. It can have harmful effects on metabolism and contribute to all sorts of diseases. In order to understand what is so bad about sugar, then you need to understand what it is made of. Before sugar enters the bloodstream from the digestive tract, it is broken down into two simple sugars… glucose and fructose.
Fructose
Fructose occurs naturally in fresh fruits, giving them their sweetness. Because of this, many people consider fructose “natural,” and assume that all fructose products are healthier than other types of sugar.
The problem with fructose is that when you consume large amounts of it in its concentrated form (agave, crystalline fructose, high-fructose corn syrup), it goes straight to your liver, avoiding the gastrointestinal tract altogether. This places a heavy toxic load on your liver, which must work very hard to process it, sometimes resulting in scarring. 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.
Glucose
Another type of simple sugar is glucose, which is the most common form of carbohydrate. It is derived from starches. When you eat starches, your body converts them to glucose, which raises blood sugar levels and supplies your body with energy. Your body metabolizes glucose via the intestinal tract, causing a rise in blood sugar. In order to return your blood sugar to a normal level, the pancreas releases insulin, which is a storage hormone. The insulin binds to the glucose and carries it to the cells that need extra energy, storing any remaining energy in long-term storage (a.k.a. fat cells). Cells that need glucose have insulin receptors that encourage glucose to enter in order to efficiently utilize it.
The problem arises when glucose is continuously high. Eating highly
processed foods, simple starches (white flour, white rice), and foods containing sugar elevate blood glucose significantly. For a while, the pancreas can handle this workload; however, over time it becomes exhausted and unable to efficiently release insulin any longer. This can result in the chronically elevated blood glucose levels found in type 2 diabetes or metabolic syndrome. At the same time, because insulin release is now inefficient, glucose is no longer being delivered to the cells that need it, resulting in cell starvation.
Artificial Sweeteners
Many people recognize the inherent health risks of sugar and fructose, and thus turn to alternative forms of sweetness. This often occurs in the form of artificial sweeteners like aspartame and sucralose. Unfortunately, these sweeteners have their own health risks, are artificial chemicals, and are neurotoxic.
The bottom line is that it is safe to eat fructose in small amounts, by eating small quantities of fresh fruit, or glucose from complex carbohydrate-rich foods including vegetables, fruits, nuts, seeds, and whole grains.
Some points to consider:
- Added sugar contains no essential nutrients and is bad for your teeth
- Due to its effects on hormones and the brain, sugar has unique fat promoting effects
- Sugar is a leading contributor to obesity in both children and adults
- Sugar raises your cholesterol and contributes to heart disease
- Because it causes massive dopamine release in the brain, sugar is highly addictive
