The World Health Organization (WHO) does not endorse specific brands or products, but they provide guidance on the consumption of sugar and sugar substitutes. WHO recommends reducing the intake of free sugars to less than 10% of total energy intake. Free sugars refer to sugars added to foods and beverages by the manufacturer, cook, or consumer, as well as sugars naturally present in honey, syrups, and fruit juices.
As for sugar substitutes, WHO acknowledges that non-nutritive sweeteners can be used as alternatives to sugar to reduce overall sugar intake and calorie consumption. Non-nutritive sweeteners, also known as artificial sweeteners or sugar substitutes, provide sweetness to food and drinks without significantly contributing to calorie intake.
Some commonly used non-nutritive sweeteners include:
Aspartame: Found in many diet soft drinks, sugar-free gums, and low-calorie desserts.
Saccharin: Often used in tabletop sweeteners, diet sodas, and other low-calorie products.
Sucralose: Found in various foods and beverages marketed as "sugar-free" or "diet."
Stevia: Derived from the leaves of the Stevia rebaudiana plant, it is available as a tabletop sweetener and used in many food products.
Cyclamate: Commonly used in tabletop sweeteners, beverages, and other low-calorie products (not approved for use in the United States).
Excessive consumption of sugar has been associated with the development of various diseases and health conditions. Here are some notable conditions linked to high sugar intake:
Obesity: A diet high in added sugars can contribute to weight gain and obesity. High-sugar foods and beverages are often calorie-dense and can lead to increased energy intake without providing substantial nutritional value. Obesity, in turn, increases the risk of numerous health problems, including diabetes, heart disease, and certain cancers.
Type 2 diabetes: A diet rich in sugary foods and drinks can increase the risk of developing type 2 diabetes. Regularly consuming high amounts of sugar can lead to insulin resistance, a condition where the body's cells become less responsive to insulin. Insulin resistance impairs the regulation of blood sugar levels, potentially leading to the development of diabetes.
Cardiovascular disease: A high intake of added sugars has been associated with an increased risk of cardiovascular disease. A diet rich in sugar can contribute to high blood pressure, unhealthy blood lipid profiles (elevated triglycerides and low levels of HDL cholesterol), inflammation, and obesity, all of which are risk factors for heart disease and stroke.
Tooth decay and gum disease: Sugar is a primary contributor to tooth decay and gum disease. When sugary foods and beverages are consumed, the bacteria in the mouth convert the sugar into acids that erode tooth enamel, leading to cavities. Additionally, the harmful effects of sugar on oral health can extend to gum disease, which can cause gum inflammation, bleeding, and tooth loss.
Non-alcoholic fatty liver disease (NAFLD): A diet high in added sugars, particularly fructose, can contribute to the development of non-alcoholic fatty liver disease. Excessive fructose consumption overwhelms the liver's capacity to metabolize it, resulting in the accumulation of fat in the liver. Over time, this can lead to inflammation and scarring, potentially progressing to more severe liver conditions such as cirrhosis.
Certain cancers: While the relationship between and cancer is complex and not fully understood, some studies have suggested a link between high sugar intake and an increased risk of certain types of cancer, including pancreatic, colorectal, and breast cancer. The mechanisms by which sugar may influence cancer development are still under investigation, but factors such as obesity, insulin resistance, and chronic inflammation may contribute to the association.
It's important to note that consuming sugar in moderate amounts as part of a balanced diet is generally considered acceptable. However, reducing the intake of added sugars and opting for healthier alternatives can help mitigate the risks associated with excessive sugar consumption and promote better overall health.
Sugar itself is not a cure for any specific disease. In fact, excessive consumption of sugar can contribute to various health problems, as mentioned earlier. However, there are instances where sugar or sugar-based treatments are used in certain medical procedures or to aid in specific therapeutic approaches. Here are a few examples:
Wound healing: Sugar, specifically in the form of medical-grade granulated sugar or honey, is sometimes used in the treatment of certain types of wounds, such as non-healing or infected wounds. This technique, known as sugar dressing or sugar therapy, involves applying sugar to the wound, which helps create a hyperosmotic environment, drawing out moisture and inhibiting bacterial growth. The process promotes wound healing by reducing bacterial load and supporting the body's natural healing mechanisms.
Fecal microbiota transplantation (FMT): FMT is a procedure used to treat certain gastrointestinal conditions, particularly recurrent Clostridium difficile infection. In FMT, fecal matter from a healthy donor is transplanted into the patient's colon to restore a healthy balance of gut bacteria. Prior to the procedure, the fecal matter is often mixed with a solution that includes sugar to preserve the bacterial viability.
Oral rehydration therapy (ORT): ORT is a method used to prevent and treat dehydration, primarily caused by diarrhea. It involves the administration of a solution containing a precise balance of salts, glucose, and water to replace fluids and electrolytes lost due to diarrhea. The inclusion of glucose (a form of sugar) in the solution aids in the absorption of sodium and water from the intestine.
It's important to note that these uses of sugar in medical procedures or therapies are specific and controlled. In general, it is recommended to consume added sugars in moderation as part of a balanced diet and to prioritize whole foods that provide essential nutrients. For the treatment of specific diseases or conditions, it is crucial to consult with healthcare professionals who can provide appropriate and evidence-based guidance.
