HNUT20010 Human Nutrition II – Nutrients in Life Stages UCD Assignment Example

To achieve optimal health, it is important to understand the different nutrients that are necessary at different life stages. In this post, we will be exploring the nutrients necessary for human growth and development from infancy to adulthood.  It will also explore how nutrient deficiencies can affect people at different stages of their lives. Finally, some tips on how to ensure that you are getting enough of the right nutrients will be provided. We will also discuss how these nutrients work together to promote overall health.

Assignment Activity 1: Understand in detail the physiology and biological changes that occur at different life stages.

At different life stages, our bodies undergo different physiological and biological changes. Here is a summary of some of the key changes that occur:

• Infancy: During infancy, our bodies are rapidly growing and developing. The brain is growing at a very fast rate, and the nervous system is wiring together. This is why infants are so receptive to learning new things. In addition, the immune system is maturing, and the digestive system is starting to become functional.
• Childhood: In childhood, bones continue to grow and strengthen, and the body reaches its adult height. The brain continues to grow and develop, reaching its full size by age 18-20. Teeth also continue to grow and erupt during childhood.
• Adolescence: During adolescence, the body undergoes many changes. Hormones are raging and the body is growing and maturing sexually. Bone density continues to increase, and the brain is still growing and developing.
• Young Adult: In young adulthood, physical growth slows down but sexual maturity continues to progress. Bone density peaks and cognitive skills continue to develop.
• Adult: In adulthood, bones stop growing but retain their density if exercised regularly. Muscle mass decreases, and the immune system begins to decline. The body reaches its maximum lifespan.

Assignment Activity 2: Understand how nutritional requirements vary according to life stage.

The nutritional requirements vary according to life stage because the body is undergoing different physiological and biological changes. For example, infants require more protein than adults because they are growing so rapidly, and adolescents need more calcium to support bone growth.

It is important to be aware of the specific nutritional needs of your own body and to ensure that you are getting enough of the right nutrients. This can be done by eating a healthy balanced diet and taking a multivitamin supplement if needed.

Some key nutrients that are necessary at different life stages include:

• Infancy: Protein, calcium, vitamin D, iron
• Childhood: Protein, calcium, vitamin D, iron, zinc
• Adolescence: Protein, calcium, vitamin D, iron, zinc, magnesium
• Young Adult: Protein, calcium, vitamin D, iron, zinc, magnesium
• Adult: Protein, calcium, vitamin D, iron, zinc, magnesium

It is also important to note that different nutrients work together to promote overall health. For example, calcium and vitamin D work together to promote bone health, and protein and zinc work together to support muscle growth.

If you are unsure of whether you are getting enough of the right nutrients, it is a good idea to consult with a healthcare professional. They can help you assess your diet and make sure that you are getting all of the nutrients you need for optimal health.

In conclusion, it is important to understand the different physiological and biological changes that occur at different life stages and to be aware of the specific nutritional requirements of your body. By doing so, you can ensure that you are getting enough of the right nutrients to support optimal health.

Assignment Activity 3: Describe in detail the relationship between diet and disease for specific public health nutrition-related disorders.

There is a strong relationship between diet and disease for specific public health nutrition-related disorders. For example, there is a link between obesity and heart disease, and poor dietary habits can lead to type 2 diabetes.

It is important to be aware of the links between diet and disease so that you can take steps to protect your health. Eating a healthy balanced diet is the best way to reduce your risk of developing chronic diseases.

Some key public health nutrition-related disorders include:

• Obesity: Obesity is a condition that occurs when a person has too much body fat. It is associated with many chronic diseases, such as heart disease, type 2 diabetes, and cancer.
• Heart Disease: Heart disease is a condition that occurs when the heart muscle does not get enough blood. It is the leading cause of death in the United States.
• Type 2 Diabetes: Type 2 diabetes is a condition that occurs when the body does not use insulin properly. It is the most common form of diabetes and can lead to serious health complications.
• Cancer: Cancer is a disease that occurs when cells in the body grow out of control. It can affect any part of the body and can lead to serious health complications.

It is important to remember that diet is just one factor that contributes to the development of chronic diseases. Other factors include lifestyle choices, genetics, and environmental factors. But by eating a healthy balanced diet, you can reduce your risk of developing chronic diseases.
