Nutrition and Age Groups

Nutrition and Age Groups

The advice given by medical practitioners is the same across both sexes.  The slight variations that may occur between males and females regarding diet and nutrient requirements are mainly because of hormonal differences between males and females.  For example, the blood lost during menstruation increases the need for daily iron intake in females. However, a healthy diet may be different across different age brackets. It is therefore critical for nursing professionals to have a deep understanding of the components of a healthy diet, especially when dealing with aged people. While focusing on the major nutrients required across different age brackets in both males and females, it is important to note that people at the age of 20 years need to consume more folate, calcium, and iron( Geissler & Powers, 2017). The major reason as to why people at the age of 20 years needs more iron is because the process of building bones is still ongoing and therefore Iron is needed to strengthen them. People in the age of 30 years need to pay special attention to magnesium and calories. The reason is that the metabolism starts slowing down and calories intake must be reduced to prevent the accumulation of excessive weight. Magnesium rich food is emphasized to regulate blood sugar and blood pressure. Diet for people at the age of 40 years maintains the same composition of being rich in mineral but should emphasize more on foods rich in antioxidants. Vitamin E and C are critical to destroy the harmful free radicals that are in the body. When it comes to people at the age of 50 years and above the diet should emphasize on calcium and Vitamin B12 as well as vitamin D( Geissler & Powers,2017).

From the article, the older adult requires more calcium as women experience rapid loss of bone during menopause. Men, on the other hand, need more calcium after attaining the age of 71 where the risk of bone fracture rises significantly. The necessity of vitamin  B12 in older people is to make nerves, red blood cells as well as DNA. It is critical to note that a majority of the older people does not produce adequate hydrochloric acid for vitamins absorption from foods and vitamin supplements are recommendable.
