Final answer:
Whole-grain bread is most likely to have the greatest nutrient density, as it provides complex carbohydrates, fiber, B vitamins, minerals, and protein without excessive calories.
Step-by-step explanation:
The food most likely to have the greatest nutrient density among the given options is whole-grain bread. Nutrient density refers to the amount of beneficial nutrients a food contains in relation to its calorie content. Whole-grain bread is rich in complex carbohydrates, which provide fiber, B vitamins, minerals, and protein. Unlike foods high in simple sugars like candy bars and sugary cereal, or high in fats like potato chips, whole-grain bread offers a balance of essential nutrients without excessive calories.
When selecting foods for nutrient density, it is important to choose those with a high concentration of nutrients and a lower concentration of calories. Whole-grain bread, for example, retains more natural nutrients as it is made from less processed grains, unlike white bread or products made from white flour which lose nutrients during processing. By prioritizing whole foods and understanding food labels, one can make healthier choices and ensure a proper balance of nutrients.
