Final answer:
Drinking three 20-oz bottles of soft drinks every day exceeds the principle of moderation in a healthy diet, and contributes to obesity, Type 2 diabetes, and cardiovascular disease. A healthful diet should instead focus on nutrient-rich foods and hydration through unsweetened beverages.
Step-by-step explanation:
Drinking three 20-oz bottles of soft drinks every day violates the principle of moderation in a healthy diet. Consuming excessive amounts of sugary drinks is a contributing factor to several health issues, including obesity, Type 2 diabetes, and cardiovascular disease. A diet that is healthful should limit the intake of added sugars and focus on hydration through water or unsweetened beverages. In addition, a balanced diet should provide nutrients beyond just energy. Nationally, overconsumption of sugary drinks is prevalent and poses serious public health concerns, as such beverages can make up a significant portion of daily caloric intake.
Instead of sugary sodas, one should opt for beverages and foods with less sodium, saturated fat, and added sugars. Moreover, employing other principles such as variety, balance, and nutrient density is crucial for a diet to be considered healthy. Drinking large amounts of sugary sodas ignores these core principles, especially when it exceeds what the body can efficiently process, as advised since the times of Cornaro.
