Explanation:

Question 9

To determine the best dietary change for macronutrient ranges, we analyze each option:

• Consuming double the rice (a carbohydrate) would likely unbalance macronutrients further, as it increases carbs without addressing protein/fat balance.
• Replacing pizza with two fried chicken breasts: Fried chicken is high in fat and protein, but the fat from frying may not help balance, and pizza has carbs, so this could skew fat/protein too much.
• Having grilled chicken instead of Barbacoa beef: Grilled chicken is leaner (less fat) than beef, which can help adjust fat intake while keeping protein and allowing better carb - fat - protein balance.
• Replacing Coca - Cola (sugar, carb) with whole milk (protein, fat, some carb): This changes carb to fat/protein but may not be the best for overall macronutrient distribution as milk has fat and protein, but the main issue with macronutrients is likely fat - protein - carb balance, and switching protein sources (beef to chicken) is more direct for balancing.

We analyze each food's carbohydrate content:

• Coca - Cola is high in sugar (a carbohydrate).
• Pizza has dough (carbohydrate - rich from flour).
• Sour cream is primarily fat and protein, with very little carbohydrate, so it's not a significant carb source.
• Black beans are a legume, rich in carbohydrates (and fiber).

We analyze each option for fiber content:

• Switching barbacoa beef to chicken: Both are animal proteins, low in fiber, so no fiber increase.
• Getting rid of pizza (which has some fiber from dough) and having spaghetti (also refined carb, similar fiber to pizza): No significant fiber increase.
• Drinking apple juice instead of orange juice: Both are juices, low in fiber (juicing removes fiber from fruit).
• Switching sourdough bread (refined) to whole wheat bread: Whole wheat bread has more fiber as it uses whole grains, which retain fiber.

Answer:

C. have grilled chicken in the burrito instead of the Barbacoa beef
