Which of the following foods is considered low in carbohydrates?

A. Increasing intake of saturated fats and limiting fiber to reduce digestive stress: This promotes heart disease and insulin resistance. Saturated fats raise cholesterol, and fiber is beneficial, not harmful.

B. Consuming a high-protein, low-carbohydrate diet with minimal physical activity: Low activity and extreme diets can increase cardiovascular risk and insulin resistance long-term.

C. Relying on vitamin supplements and avoiding all sources of dietary fat: This ignores whole food nutrition. Some fats (e.g., omega-3s) are heart-healthy and essential for metabolic function.

D. Engaging in regular physical activity, maintaining a healthy weight, and following a diet rich in whole grains, fruits, and vegetables. These practices improve insulin sensitivity, control weight, and lower blood pressure and cholesterol.

A. Mouth
Carbohydrate digestion begins here via salivary amylase, but it's minimal and not the main site of absorption.

B. Transverse colon
By this point, most carbs are already absorbed. The colon mainly absorbs water and electrolytes.

C. Duodenum
The duodenum, part of the small intestine, is where pancreatic amylase continues carbohydrate digestion, and absorption of monosaccharides begins.

D. Stomach
The acidic environment inactivates salivary amylase; little to no carb digestion occurs here.
