Question

select the correct answer.
which kind of diet helps prevent cancer?
a. a diet high in protein and low in carbohydrates
b. a diet high in fiber and low in saturated fats
c. a diet high in calcium and low in sugar

Explanation:

• Option A: A diet high in protein and low in carbohydrates is often associated with weight - loss diets (like some keto - based diets) rather than cancer prevention. Excessive protein intake (especially from red and processed meats) may have negative health impacts, and while carbohydrate control is important in some diets, it's not the key for cancer prevention in this context.
• Option B: A diet high in fiber (from fruits, vegetables, whole grains) helps with digestion, can reduce inflammation, and may play a role in preventing certain cancers (e.g., colon cancer). Low - saturated - fat diets (saturated fats are mainly from animal products like butter, fatty meats) are beneficial as a high intake of saturated fats is linked to various health issues, and reducing them can be part of a cancer - preventive diet. Fruits, vegetables, and whole grains (high - fiber foods) are also rich in antioxidants and other phytochemicals that may have anti - cancer properties.
• Option C: While calcium is important for bone health and reducing sugar intake is good for overall health (to prevent diabetes, dental problems, etc.), a diet high in calcium and low in sugar is not specifically the most well - known combination for cancer prevention compared to the fiber - and - low - saturated - fat combination.

Answer:

B. a diet high in fiber and low in saturated fats
