Final answer:
Essential substances in food that contribute to good health are nutrients, which support bodily functions and protect against diseases. Chemistry helps us understand the role of these nutrients, suggesting a diet rich in whole foods and antioxidants and a lifestyle that includes regular exercise and proper hydration strongly contributes to overall health.
Step-by-step explanation:
The substances in food that are important to keeping you healthy are broadly known as nutrients. They provide sustenance, help in maintaining a clean and healthy body, support recovery during illnesses, and contribute to the efficient functioning of the body protecting from various diseases. Poor dietary choices contribute significantly to non-communicable diseases such as obesity, cardiovascular diseases, Type 2 diabetes, and certain types of cancer. Healthy eating and a balanced diet are thus crucial.
Chemical substances and processes play a fundamental role in nutrition, from the digestion of food to the metabolic reactions that produce energy and build tissues. Chemistry is essential to understanding how nutrients function in the body. Nutrients and energy-dense foods should be carefully chosen to ensure that your diet provides all the necessary components for good health while avoiding excessive calories. Substituting high-calorie foods with fruits and vegetables is one way to shift towards a healthier diet.
It's not just about avoiding synthetic chemicals; a healthy diet involves consuming a variety of whole, fresh, unprocessed foods rich in nutrients and antioxidants that promote health and reduce the risk of chronic diseases. Along with a balanced diet, lifestyle factors like adequate hydration, regular exercise, and understanding your target heart-rate zone for optimal cardiovascular activity are critical elements of a healthy lifestyle.
