Welcome to this informative session on “Why Nutrition is a Key Component of a Healthy Life”. We all know that good nutrition is essential for maintaining good health, but many of us fail to understand the importance of proper nutrition in our daily lives. Good nutrition is not just about eating a balanced diet, but it also involves understanding the nutrients that our body needs and how to get them from the food we eat. In this session, we will explore the various aspects of nutrition and how it affects our overall health and well-being. So, let’s dive in and discover the fascinating world of nutrition and how it can help us lead a healthier and happier life.
Macronutrients are the essential nutrients that our body requires in large amounts for its proper functioning. They are divided into three categories: carbohydrates, proteins, and fats. Each of these macronutrients plays a crucial role in maintaining our overall health and well-being.
- Carbohydrates: Carbohydrates are the primary source of energy for our body. They are found in foods such as grains, fruits, vegetables, and dairy products. The recommended daily intake of carbohydrates varies depending on age, gender, and physical activity level, but it is generally advised to consume 45-65% of daily calories from carbohydrates. Consuming too many refined carbohydrates, such as white bread and sugary drinks, can lead to weight gain, increased risk of heart disease, and other health problems.
