Final answer:
The statement is FALSE; good nutrition must be outcome-based. Nutrition guidelines rely on evidence of health outcomes, emphasizing the importance of essential nutrients, balanced food intake, and physical activity for overall health.
Step-by-step explanation:
The statement 'Good nutrition should be more theoretical and not based on outcomes' is FALSE. Nutrition recommendations and practices should be strongly grounded in evidence from actual health outcomes to ensure they are effective in promoting health and preventing disease. This is supported by understanding essential nutrients, the impact of micronutrient deficiencies, and the role of diet and physical activity in preventing obesity and chronic diseases.
Essential nutrients are compounds that cannot be synthesized by the body and must come from the diet because they are critical for proper bodily function. Additionally, restricting children's access to junk food may help prevent obesity, but it is not sufficient on its own; physical activity and healthy eating habits must also be fostered as a part of comprehensive nutrition education. Lastly, the balance between food intake and energy expenditure is crucial in maintaining health and preventing obesity, which directly affects the risk of illnesses like type-2 diabetes and cardiovascular disease.
