What is natural sugar called? A complete guide

4 min read

Overconsumption of added sugars is linked to a higher risk of heart disease, type 2 diabetes, and obesity. However, the sugars found naturally in whole foods like fruits and milk, which are collectively known by various scientific names like fructose and lactose, have a much different impact on our health. Understanding the distinct terminology and nutritional differences is crucial for making informed dietary choices.

Quick Summary

Natural sugars are carbohydrates that occur naturally in foods such as fruit and milk. These include several types like fructose, lactose, and glucose. It is important to distinguish them from added sugars, which are concentrated sweeteners incorporated during processing and often lack nutritional value.

Key Points

  • Diverse Terminology: There is no single name for natural sugar; it includes different scientific compounds like fructose (fruit sugar) and lactose (milk sugar).

  • Natural vs. Added: Natural sugars are found within whole foods and are processed slowly by the body, whereas added sugars are concentrated sweeteners digested rapidly.

  • Beneficial Nutrients: Whole foods containing natural sugars also provide essential nutrients like fiber, vitamins, and minerals that are stripped from added sugars.

  • Read Labels: Look for "Added Sugars" on the Nutrition Facts label to distinguish between natural and added sugar sources in packaged foods.

  • Healthier Choices: Choosing whole fruits over fruit juices and unsweetened dairy products helps limit intake of added sugars and provides more nutritional value.

  • Concentrated Sweeteners: Even natural sweeteners like honey and maple syrup are considered added sugars because they are concentrated and lack the fiber of whole foods.

The quest for a healthier diet often begins with understanding the food we eat, and few topics are more confusing than sugar. While most people associate 'sugar' with the white granules in a sugar bowl, the reality is far more complex. The term for what is natural sugar called is not a single name but a collection of chemical compounds, each with unique properties and sources. These naturally occurring carbohydrates are found in whole, unprocessed foods and are distinct from the added sugars prevalent in many manufactured products.

The Scientific Names for Natural Sugar

At a chemical level, all sugars are classified as carbohydrates, which are made up of carbon, hydrogen, and oxygen atoms. The simplest form of these are monosaccharides, or "single sugars." When two monosaccharides link together, they form a disaccharide, or "double sugar". The following are the most common names for natural sugar.

Monosaccharides (Simple Sugars)

  • Fructose: Often called "fruit sugar," fructose is a simple sugar found in fruits, some vegetables, and honey. It is known for being the sweetest of all naturally occurring sugars.
  • Glucose: The body's primary energy source, glucose is the most common monosaccharide. It is found in fruits and vegetables and is also produced by the body from other carbohydrates. Glucose is also known as dextrose.
  • Galactose: This monosaccharide is primarily found as a component of lactose, the sugar present in milk and dairy products.

Disaccharides (Double Sugars)

  • Lactose: Known as "milk sugar," lactose is a disaccharide formed from one glucose and one galactose molecule. It is found exclusively in milk and dairy products.
  • Sucrose: Commonly known as table sugar, sucrose is a disaccharide made of one glucose molecule and one fructose molecule. While highly refined sucrose is an added sugar, it also occurs naturally in plants like sugar cane, sugar beets, fruits, and vegetables.
  • Maltose: Known as "malt sugar," this disaccharide consists of two glucose molecules. It is formed in germinating grains like barley.

The Crucial Difference: Natural vs. Added Sugar

While the chemical names for natural and added sugars can be the same (e.g., sucrose), their nutritional and health impacts are drastically different. The key distinction lies in their source and how they are processed by the body.

Natural Sugar

  • Source: Found naturally within whole foods, such as fruits, vegetables, and dairy.
  • Nutritional Value: Comes bundled with fiber, vitamins, minerals, and antioxidants.
  • Body Processing: The fiber content in whole foods slows down the digestion and absorption of the sugar, preventing rapid spikes in blood glucose levels.

Added Sugar

  • Source: Sweeteners and syrups added to foods during processing, cooking, or at the table.
  • Nutritional Value: Provides empty calories with little to no other nutrients.
  • Body Processing: The body digests and absorbs added sugars very quickly, which can lead to a rapid increase and subsequent crash in blood sugar.

Natural Sugars vs. Added Sugars: A Comparison

Feature Natural Sugars (in whole foods) Added Sugars (in processed foods)
Primary Source Fruits, vegetables, dairy, grains Sweeteners and syrups added during manufacturing
Nutrient Content Packaged with fiber, vitamins, minerals Provides empty calories, lacking nutrients
Absorption Rate Slower, due to accompanying fiber Rapid, leading to blood sugar spikes
Associated Health Effects Associated with stable blood sugar and overall health Linked to obesity, diabetes, and heart disease
Example Fructose in a whole apple High-fructose corn syrup in soda

The Impact of Natural Sugars on Your Health

Consuming natural sugars from whole foods is not a major concern for most people and is a healthy part of a balanced diet. The nutrients in whole foods, like the fiber in an apple or the protein in milk, create a protective effect. For example, the fiber in fruit delays the digestive process, preventing the sharp blood sugar spikes that can occur from consuming added sugars in isolation. The overall nutrition provided by these foods vastly outweighs the potential negative effects of their sugar content alone. However, this does not mean natural sweeteners like honey or agave syrup can be consumed without limit. Since they are concentrated sugars, they are considered added sugars by nutritionists, even if their origin is natural.

How to Reduce Added Sugar and Choose Natural Options

Reducing added sugar intake involves reading food labels carefully and choosing whole foods over processed ones. The Nutrition Facts label on packaged foods now includes a line specifically for "Added Sugars" to help consumers make better choices. Limiting intake to under 10% of total daily calories, as recommended by the Dietary Guidelines for Americans, is a good goal. The American Heart Association recommends even stricter limits.

To satisfy a sweet tooth, opting for whole fruits, which come with beneficial fiber, is a healthier choice than fruit juice, which lacks fiber and can cause a quicker sugar rush. Similarly, unsweetened plain yogurt contains natural lactose, while many flavored yogurts have significant amounts of added sugar.

Conclusion

The name for what is natural sugar called is not a single term, but rather a collection of chemical compounds like fructose, glucose, and lactose. These sugars, when consumed in their natural state as part of whole foods like fruits and dairy, are accompanied by essential nutrients that are beneficial for health. The real health concern is with added sugars, which are concentrated sweeteners often added to processed foods and beverages. By understanding this key difference, individuals can make more conscious dietary choices to support their long-term health and well-being. Focusing on a diet rich in whole foods and limiting processed products is the most effective way to manage sugar intake.

The primary sugar found in fruit is called fructose. Fruits also contain smaller amounts of glucose and sucrose.

The sugar naturally present in milk and dairy products is called lactose. Lactose is a disaccharide made of glucose and galactose.

Although derived from a natural source, honey is considered an added sugar because it is a concentrated sweetener added to food, rather than being part of a whole, unprocessed food.

The fiber in fruit slows down the digestion of its natural sugar (fructose), preventing rapid blood sugar spikes and providing a more stable energy source. Added sugars, without fiber, are absorbed quickly.

While all sugars are converted into energy, the speed of processing differs significantly. Sugars from whole foods are digested slower due to fiber, whereas added sugars are absorbed rapidly, leading to quick blood sugar changes.

For most people, the natural sugar in fruit is not a cause for concern because it's accompanied by beneficial fiber, vitamins, and minerals. The overall nutritional benefits of fruit outweigh the sugar content.
