In most cases, healthy diet is the personal choice of an individual, nevertheless, its importance is predetermined by the ability to prevent a variety of diseases that can shorten human life and even be terminal. Unhealthy eating habits, including the increased consumption of trans-fats, sugars, and simple carbohydrates can lead to the development of heart diseases and type 2 diabetes (NHS Health Scotland, 2020). Moreover, a diet that exceeds a particular’s person daily norm of calories leads to gaining weight and poses additional health problems associated with obesity. For example, instead of eating junk food, a diet that is rich in fruits, vegetables, dairy products, whole grains, and fatty fish, such as salmon, can help to reduce cholesterol levels and maintain normal blood pressure (NHS Health Scotland, 2020). It is important to keep bones and teeth healthy during the course of life. Healthy eating that includes the consumption of calcium lowers the risk of developing osteoporosis which is associated with bone weakening as people grow older (NHS Health Scotland, 2020). Calcium is present in dairy products, sardines, green vegetables, cereals, and soya products, making the diet of an average person diverse. Calcium is absorbed with the help of vitamin D, the levels of which can be maintained through the consumption of such products as fish and fortified cereals. Additionally, a healthy diet has a direct impact on the digestive system. Healthy diet helps to keep weight within the acceptable range for every individual. Conversely, obesity can significantly restrict people from leading a healthy lifestyle due to limited physical ability.
