Healthful diet

Healthful diet

provides a proper balance of energy and nutrients that supports health of the individual at their age and stage of life

Moderate

not too little and not too much in terms of nutrient intakes; linked to nutrient recommendations and DRIs; e.g. too much vit C causes kidney problems and nausea, too little causes skin problems

Nutrient-dense

nutrient to energy ratio, higher quality foods that provide many nutrients vs. processed foods/drinks that provide little nutrients but equal amount of calories

Balanced

coordination of the foods consumed to meet nutrient needs

Varied

choice of different foods within a food group, selecting a variety increases likelihood of meeting needs

Factors that drive food choice

social and cultural cues, sensory data, learned factors/environment
