Sugar: (Part 7) Nitric Oxide

It's been raining almost everyday lately. Winter time in most western countries, United States, China, Taiwan, etc. Bad weather occurring in various countries, even airport in London was shut down. Something came to my mind, what I want to write in this post. Lighting strikes. You may be wondering, how on earth does lighting strikes related to sugar? Well, of course there is no direct relation between these two, but I'm referring to nitric oxide. Anyone heard of it? 

Nitric oxide, is a toxic gas, found in automobile exhaust as well as lighting strikes. When vehicle engines reach high temperature, nitric oxide is produced, and while during a lighting strike, nitrogen reacts with oxygen to produce nitric oxide as well. And what does nitric oxide has to do with sugar? Keep reading folks.

As uric acid spills into the blood after you consume a food or beverage that's high in fructose or purines, it shuts down production of a gas called nitric oxide. Healthy circulation requires blood vessels to expand and contract. To expand blood vessels, endothelial cells that line the blood vessel walls produce nitric oxide. This important gas acts as a messenger, instructing the smooth muscle cells that surround blood vessels to stop contracting. As uric acid blocks the release of nitric oxide, blood vessels cannot relax and dilate, which raises blood pressure. Thus, high blood pressure occurs. Now got the point here?

Three scientists who proved its importance in cardiovascular system, won the Nobel Prize. Before this discovery, most scientists believed that nitric oxide is simply a toxic gas, a free radical, mainly found in automobile exhaust and lighting strikes. Then, it was discovered that it plays a crucial role in promoting healthy circulation by causing the blood vessels to relax. You must be wondering, if it is a free radical, wouldn't it be damaging to our body? The thing is, our body produces only a small amount of nitric oxide, enough to keep blood vessels open and flowing, but too little to do any damage.

Today, the beneficial role of nitric oxide in human health is widely accepted. Let me ask some of you guys out there reading this right now. Ever suffer from erectile dysfunction? I know I know, what's ED has to do with sugar or nitric oxide? I'm sure you heard of ED drugs such as Viagra ,Cialis and Levitra. One of my colleagues is a regular consumer of ED drugs. The knowledge that nitric oxide promotes blood flow in the penis, allowed drugmakers to develop erectile dysfunction treatments. Nitric oxide in our body has multiple benefits apart from relaxing blood vessels. So guys, now you know how ED drugs works. But my advise, stay away from ED drugs, build a healthy reproductive system from inside out. Diet and exercise. Maintain a good BMI, control carbs consumption, and most important of all, lose weight in a healthy way.

Losing weight can be a great challenge. Most people who manage to shed some pounds, eventually regain back at least some of the weight, if not all. The modern world makes the gaining weight all together too easy. We got fast food outlets open 24hrs, we got automobiles bringing us to get food supplies, we don't need to hunt for food and thus burn less calories, compared to our primal ancestors. Evolution gave us bodies programmed to seek and stockpile calories in fat tissue as a backup energy source in case of famine. Guess what, the famine never comes, and we keep eating more and more. Instead, we live in land of plenty, Burger Kings, McDonalds, KFC, Baskin Robbins, Dunkin Donuts, etc. They are all short drive away for most people.

Unlike our prehistoric ancestors, we are all surrounded by food. Food is everywhere, 'mamak' stalls open 24hrs, people swarming these outlets even in the wee hours at 3 or 4am eating food filled with trans fat, sugar, and MSG. Then again, it's not as though we walk or jog to the nearest restaurant or grocery. Lack of exercise and the labor saving devices have resulted in an overall drop in physical activity amongst us, ensuring that many of the calories we store so efficiently in our fat tissue remain there.

Right now, I will present to you fructose powerful influence on your weight in number of ways.

  • Fructose makes food tasty and appetizing, which coaxes you into eating more calories than your body needs.
  • Unlike other form of sugar, fructose does not trigger the release of important hormone signals to the areas of the brain that control appetite. In other words, even large servings of fructose rich foods leave you hungry. 
  • Fructose damages healthy fat cells, making them sick and causing them to fill up with excessive amounts of fat.
  • Fructose has 7 times more devastating effects of AGE products, comparing to glucose. 

Of course, eating too much of any food will make you gain weight. Fructose makes food taste good, and once you start eating a tasty food, stopping can be difficult. As a result, it is easy to overindulge when you eat sweets. A taste for sweetness appears to be universal. If you offer someone whom you just met, who never tasted chocolate before, you will make a new friend. Research also shows that a love of sweetness is programmed into the brains of mammals, probably so that infants will indistinctly nurse on mother's milk, which has slight sweet taste, due to a type of sugar called lactose.

There is little doubt that sweetness affects our emotions. Studies have shown, for instance, that crying newborns calm down when given a sweetened liquid, but continue with loud cries, when fed an unflavored beverage. The yearning for sweet foods seems to intensify as we age. Sugar is a drug, and addictive food substance. Everyone just can't get enough of sugary food.
