Which key principle of developmental systems theory underlies the observation that certain experiences bias children from birth to be predominantly left- or right-handed, but the process of development of hand preference can be delayed or even reversed (e.g., from left to right or right to left) within the first 5 years of postnatal development?

Answer:

There are several reasons why it is beneficial to eat fresh food instead of processed food:

1. Nutritional value: Fresh food tends to be higher in essential nutrients such as vitamins, minerals, and antioxidants. Processing often involves adding preservatives, artificial flavors, and excessive amounts of salt, sugar, or unhealthy fats, which can reduce the nutritional quality of the food.

2. Reduced additives and chemicals: Fresh food is generally free from artificial additives, food colorings, and preservatives that are commonly found in processed food. These additives may have negative effects on health, such as allergies, sensitivities, or long-term health issues.

3. Higher fiber content: Fresh food, especially fruits, vegetables, and whole grains, is typically rich in dietary fiber. Fiber helps maintain a healthy digestive system, aids in weight management, and reduces the risk of certain diseases such as heart disease and type 2 diabetes.

4. Lower sodium and sugar levels: Processed food often contains high levels of sodium and added sugars. Excessive consumption of these can contribute to health problems like high blood pressure, obesity, and increased risk of chronic diseases. Fresh food, on the other hand, can provide natural flavors without the need for excessive salt or sugar.

5. Better control over ingredients: When you choose fresh food, you have more control over the ingredients you use in your meals. This allows you to prioritize whole, unprocessed ingredients and avoid harmful additives or unhealthy cooking methods.

6. Taste and variety: Fresh food generally offers superior taste and a wider variety of flavors compared to processed food. By incorporating fresh ingredients into your meals, you can enjoy the natural and vibrant flavors of fruits, vegetables, herbs, and spices.

Overall, choosing fresh food over processed food can contribute to a healthier diet and lifestyle. It provides greater nutritional value, reduces exposure to additives and chemicals, and allows for more control over the ingredients you consume.

Hopefully this helps! Good luck!

Final answer:

Eating fresh food instead of processed food is desirable due to its natural components and nutritional benefits. Processed food often contains unhealthy additives, while fresh food provides essential nutrients like vitamins, minerals, and fiber, supporting overall health and well-being. Hence, it's advisable to choose fresh over processed food.

Explanation:

Consuming fresh food over processed food is important for good health. Processed foods often contain preservatives, artificial ingredients, and high levels of sodium and sugar, which can lead to multiple health issues like heart disease, obesity, and diabetes. On the other hand, fresh food is free from these harmful additives and is rich in nutrients like vitamins, minerals, and fiber that your body requires to function optimally.

For instance, fresh fruits and vegetables are naturally low in fat and high in fiber, promoting good digestive health and weight management. Similarly, lean meat, fish, eggs, and nuts, when eaten fresh, provide essential proteins and fats. Regularly eating fresh food can also improve skin health, enhance mood, and boost energy levels.

In conclusion, while processed foods can offer convenience and longer shelf life, they lack the nutritional profile and natural goodness of fresh foods. For the sake of health and well-being, it is recommended to choose fresh over processed food when possible.
