Identify how Nutritioanl Needs Change due to Age, Lifestyle Choices and State of Health

How Nutritional Needs Change with Age

Infants and Young Children have high energy needs relative to their body size due to rapid growth, development, and higher basal metabolic rate.
Required are higher amounts of proteins and fats to support tissue building, immune function, and brain development, particularly Omega-3 fatty acids.
Vitamins and Minerals like Vitamin D, calcium and iron are essential for bone and brain development and the prevention of anaemia.
The diet of Teenagers should be rich in iron, particularly for girls after the onset of menstruation. Adolescents also need more energy to fuel their growth spurts.
Adults require a balanced intake of macronutrients and micronutrients. Caloric intake should be carefully managed to prevent unwanted weight gain as metabolism starts to slow.
As we age, the need for calories decreases but the need for protein, fibre, vitamins and minerals increases. Particularly important are calcium and Vitamin D for bone health and B vitamins for brain health.

How Nutritional Needs Change with Lifestyle Choices

Physically Active Individuals need more energy and protein to fuel and recover from their activities, along with hydration and electrolytes to maintain proper bodily function.
Those following a Vegan or Vegetarian Lifestyle need to ensure suitable intake of vitamins, minerals and essential fatty acids traditionally found in animal products. Protein sources should also be varied and ample.
Moderate consumption of alcohol can lead to a need for increased amounts of B-vitamins used to metabolize the alcohol.

How Nutritional Needs Change with State of Health

Pregnancy and Lactation increase a woman’s need for many nutrients, particularly iron, folate, calcium, and energy to support the growth and development of the baby.
Conditions like Diabetes and Heart Disease can require limiting certain nutrients like fats and sugars and increasing others like fibre.
Individuals with Food Allergens should ensure they receive the nutrients commonly provided by their allergenic foods from alternative sources.
Conditions like Osteoporosis and Anaemia can prompt a need for increased calcium and iron intake, respectively.

Conclusion

Nutritional needs are dynamic and change throughout life under the influence of age, lifestyle choices, and state of health.
Understanding these changes is key to maintaining optimal health and wellness through appropriate diet.
