Fructose

What is Fructose?

Fructose is a type of sugar found naturally in fruits, vegetables, and honey. It is also a key component of sucrose (table sugar) and high-fructose corn syrup (HFCS). Fructose is metabolised primarily in the liver, where it can be converted into glucose or stored as fat. While it is naturally occurring in many foods, excessive consumption of fructose, especially from processed foods containing HFCS, has been linked to various health issues, including obesity and insulin resistance.

Why is Fructose important?

Fructose is important because it:

• Provides a source of energy that can be used by the body for immediate fuel or stored for later use.
• Is part of natural foods like fruits, providing essential vitamins, minerals, and fibre alongside the sugar.
• Can affect metabolic health if consumed in excess, especially from processed foods with high-fructose corn syrup, contributing to weight gain, fatty liver disease, and insulin resistance.

While fructose in whole fruits is generally considered healthy, excessive intake of added sugars can lead to negative health effects.

How does Fructose affect health?

Fructose affects health by:

• Contributing to weight gain: Excess fructose consumption, particularly from sugary drinks and processed foods, can lead to fat accumulation in the liver and increase the risk of obesity.
• Increasing the risk of metabolic disease: High fructose intake can cause insulin resistance, which is a precursor to type 2 diabetes and other metabolic disorders.
• Promoting fatty liver disease: When consumed in excess, fructose can lead to non-alcoholic fatty liver disease (NAFLD) as it is metabolised in the liver and can be converted into fat.
• Affecting gut health: High fructose levels can alter the gut microbiome, leading to digestive issues such as bloating and gas.

Moderation is key when it comes to fructose consumption, especially from processed sources like high-fructose corn syrup, to avoid adverse health effects.

How can I reduce Fructose intake?

To reduce fructose intake:

• Limit sugary drinks and processed foods that contain high-fructose corn syrup, as these are major sources of excessive fructose.
• Consume more whole fruits, which contain naturally occurring fructose along with beneficial fibre and nutrients that offset negative effects.
• Read food labels to check for hidden sources of added fructose, such as in sauces, condiments, and baked goods.
• Opt for healthier sweeteners like stevia or monk fruit, which do not contribute to excessive fructose consumption.

By reducing intake of processed sugars and opting for whole, unprocessed foods, you can help prevent the negative health effects associated with excess fructose consumption.

Key Takeaways from a Nutritionist

• Fructose is a natural sugar found in fruits, but excessive consumption, especially from processed foods and sugary drinks, can lead to weight gain, metabolic diseases, and liver issues.
• Limit fructose intake from processed foods and opt for whole fruits, which provide essential nutrients and fibre along with sugar.
• Read food labels to avoid hidden sources of added fructose, and focus on a balanced diet to support metabolic and digestive health.
