Final answer:
Adequacy, balance, and moderation are important principles in nutrition. Poor nutrition can lead to various risks such as malnutrition, obesity, and nutrient deficiencies.
Step-by-step explanation:
Adequacy in nutrition refers to consuming enough of each essential nutrient, as well as fiber and adequate calories, to meet the body's needs.
Balance in nutrition means getting appropriate amounts of all nutrients in the diet, without consuming one nutrient at the expense of another.
Moderation in nutrition means avoiding extremes, neither eating too much nor too little.
Three risks of poor nutrition include malnutrition, which can include undernutrition, overnutrition, and unbalanced nutrition; obesity, which can lead to various health problems; and nutrient deficiencies, which can result in specific health issues.
