Exercises: A healthy diet and the "Plato del Bien Comer"

In Mexico, the "Plato del Bien Comer" (Plate of Good Eating) organizes foods into three groups: vegetables and fruits; cereals and tubers; legumes and foods of animal origin. Explain which nutrients each group mainly provides and why a healthy diet combines all three at every meal instead of relying on just one.

Two meals have almost the same energy content (about 700 kcal): the first is a hamburger with fries and a soft drink; the second is a plate with chicken, rice, beans, a vegetable salad, and plain water. Without saying that one "makes you fat" and the other doesn't, compare both meals in terms of nutrient groups, the variety of the "Plato del Bien Comer", and the quality of the energy they provide. Which one would you choose as an everyday meal and why?
