Which of the following statements about fructose is true?

1. Fructose is a disaccharide found naturally in fruits.

2. Fructose has a greater glycemic effect compared with sucrose.

3. Beverages with high fructose corn syrup should be limited or avoided.

4. People with diabetes should avoid all types of fructose due to the effect on triglycerides.

Research indicates that high fructose intake can lead to various metabolic issues, including an increased risk of obesity, insulin resistance, and elevated triglyceride levels, which are particularly concerning for individuals with or at risk for diabetes. It's essential to recognize that not all fructose is harmful; naturally occurring fructose in whole fruits is accompanied by fiber, vitamins, and minerals which contribute positively to health. However, the concentrated sources found in sweetened beverages are much different. Therefore, limiting or avoiding these products is a sound recommendation for maintaining overall health and managing diabetes effectively. The other statements about fructose, while related to its characteristics or effects, do not provide a comprehensive or accurate understanding of how fructose, especially in the context of added sugars, impacts health. For instance, fructose is indeed a monosaccharide found in fruits and is part of sucrose, which is a disaccharide, but the health implications of its consumption are the crux
