🍞 Carbohydrates are the body's primary energy source, especially for the brain and nervous system, which rely heavily on glucose.

🍞 They are essential for preventing protein breakdown, preserving muscle mass, and supporting metabolic balance.

🍞 Carbohydrates provide fiber, which aids digestion, regulates blood glucose, and lowers cholesterol.

🍞 Insufficient carbohydrate intake leads to ketosis, fatigue, impaired cognition, and muscle wasting.

🍞 Therefore, this statement correctly identifies carbohydrates as essential for normal physiological function and health.

Sucrose does not lead to tooth decay

🍞 Sucrose is well-known for promoting dental caries, as oral bacteria metabolize sugar to produce acids that damage enamel.

🍞 High sucrose intake is a major risk factor in pediatric and adult tooth decay.

🍞 This statement contradicts solid evidence linking sugar to dental disease.

🍞 Preventing dental caries involves lowering sugar exposure, brushing, and fluoride use.

🍞 Therefore, this statement is false and misleading.

Fiber is considered a simple carbohydrate

🍞 Fiber is a complex carbohydrate, not a simple one, because it has long polysaccharide chains that cannot be fully digested by human enzymes.

🍞 It is found in whole grains, vegetables, legumes, and fruits—foods rich in complex, not simple, carbs.

🍞 Fiber slows digestion, stabilizes blood glucose, and promotes satiety.

🍞 Simple carbohydrates include sugars (glucose, fructose, lactose), not fiber structures.

🍞 Therefore, labeling fiber as a simple carbohydrate is incorrect.

One gram of carbohydrates is equal to 15 calories

🍞 Carbohydrates provide 4 calories per gram, not 15.

🍞 The number “15” applies only to carbohydrate-counting exchanges in diabetes meal planning, not caloric content.

🍞 Misunderstanding this value can lead to serious dietary miscalculations.

🍞 The caloric content of carbs is universally recognized as 4 kcal/g, aligning with protein.

🍞 Therefore, this statement is nutritionally incorrect.
