In this note we relate the real impact of food and diet drinks with artificial sweeteners intense content, as though provide fewer calories than standard products, there is still no conclusive evidence that these "light" products actually contribute to prevent overweight and obesity.
At present there are at least 200 chemicals with sweetening power, without adding calories, or very few, the food or beverage is added.
The sweetening power is the ability to stimulate the sweetness of a substance, and is established by comparison with table sugar or sucrose.
Types of sweeteners
Sweeteners can be classified according to their origin (natural or artificial) and calories (nutritive or non-nutritive) as follows:
NaturalesEdulcorantes nutritive sweeteners and natural and artificial sweeteners
Represented by the natural sugar found in food.
monosaccharides glucose, fructose, galactose.
disaccharides sucrose, lactose, maltose.
trisacáradios: maltotriose, maniotrosa.
Nutritive sweeteners derived from natural products
starch products from glucose, glucose syrup and isoglucose.
products from sucrose: invert sugar.
alcoholeso sugar polyols mannitol, sorbitol, xylitol, maltitol, lactitol.
neoazúcares: fructo-oligosaccharides.
Intense sweeteners or non-nutritive
chemical or artificial sweeteners: aspartame, acesulfame K, saccharin, cyclamate.
sweeteners plant origin extracted from some plants, but its use at present is minimal, because of their high cost and most of them are still experimental. They are: thaumatin, stevioside (stevia), monellin, dihydrochalcone.
The tryptophan and glycine, amino acids have sweet flavor and sweeteners are also used as additives.
Features polyols sweeteners
In general we can say:
Polyols or polyols, unless sweeten sugar.
Industrially obtained from corn starch, they are also found naturally in fruits, even in small quantities.
The most frequently used polyols are sorbitol, mannitol and xylitol.
Advantages of polyols:
They are poorly absorbed by the body, so low calorie, ie less than sugar.
do not increase the blood sugar level, so they are well tolerated by diabetics.
not generate cavities
to retain water, keep food and products that were added moist and fresh, so they are used as additives.
Disadvantages of polyols:
if consumed in large quantities cause diarrhea and flatulence.
They should not be given to infants younger than 3 years, as it may provoke intestinal disorders.
Features intense sweeteners
With respect to all chemical sweeteners we can say that all of them can have undesirable side effects in our bodies and that most of the foods or products that have added sweeteners are not very healthy: soft drinks, preserves, ice cream, candy, candy, etc. .
We will stop in the intense sweeteners because they are the most powerful and the most used in the industry. They are called intense because with just a few milligrams have a great sweetening power.
The potential toxicity of these sweeteners has always been questioned, and even today the debate continues. The United States has removed from the list of safe sweeteners saccharin and cyclamate.
The most used and most criticized artificial sweeteners are: saccharin, cyclamate, aspartame and acesulfame K.
Advantages of artificial sweeteners:
They do not provide energy as calories,
They are practical: Because commercial form.
Disadvantages:
They are not nutritious, only add sweetness. Intense sweeteners sweeten more than table sugar or sucrose;
Present health risks or adverse effects;
They may cause increased appetite with consequent weight gain.
Sweeteners in low-calorie or light products
The light products are those more intense sweeteners have, and some of them are reduced fats containing therefore given the high demand for these products exists cite, if in the end they are a solution or a trap for health .
Benefits and advantages
The advantages of light products lies primarily in how useful their consumption to those suffering from diabetes, obesity, and other metabolic diseases, without the need to give up your palate flavors consider pleasant.
Disadvantages or drawbacks "In many cases usually experience a real increase in anxiety for sweets and eat more"
Induce excessive consumption: most people who use these products to see which are low in calories, unconsciously consume more than if it were the normal product. So in the end the total calorie count is higher (more quantity, more calories).
Unhealthy and highly processed foods: many highly processed foods that have lost some of their vitamins, and also contain many food additives. In general, food is unwise from the point of view of healthy eating.
Opposite effect: according to recent studies, it has been found, particularly aspartame, which can lead to an increased appetite and therefore food consumption, causing weight gain.
By consuming these products, our nerve center announces the arrival of sugars. But if these sugars in the end fail, our deceived neurohormonal system reacts as if it had really taken with the consequent increase in body weight.
Nutritional advice
To conclude our best advice, will always consume these products or avoid moderate form waives the sweet taste that we provide, ensuring 100% but our health.
