The minimum recommended daily carbohydrate intake is set at 130 grams to support essential brain function. The brain relies primarily on glucose for energy, and this threshold of carbohydrates ensures that there is enough glucose available to meet the brain's needs, especially when glycogen stores are depleted from the liver. This recommendation is derived from dietary guidelines, which emphasize that carbohydrates are a crucial macronutrient in the diet, providing energy and facilitating various bodily functions.

While lower carbohydrate intakes might be suitable for some individuals, especially under specific dietary regimens or medical guidance, the 130 grams serves as a standard to help maintain optimal cognitive function and overall metabolic health. This intake aligns with recommendations from health organizations and recognizes that sufficient carbohydrate consumption is important for preventing cognitive impairment and supporting physical activity.

Thus, the correct answer aligns with established nutritional guidelines that prioritize both health maintenance and energy requirements for the brain, making 130 grams the minimum standard for carbohydrate intake.
