There is no one-size-fits-all approach to nutrition. It is important to understand that specific demographic groups, like the young and elderly, have distinct nutritional needs. This article will serve as a comprehensive guide on the dietary needs of the young and the elderly in a simple and easy-to-understand language.
Nutritional Needs For The Young
Understanding the unique nutritional needs of young individuals is essential for their growth and development.
A balanced diet always have a positive impact on overall wellbeing.
Caloric Intake
While calculating calories for adults is straightforward, it’s trickier for the young. We consider age, gender, height, weight, activity level, and growth rate. Young individuals are growing and tend to be more physically active. To fuel their development, they need adequate daily calories. For athletes, even more care is required to support training and recovery.
You can check out the Institute of Medicine’s Dietary Reference Intakes (DRI) recommendations for a starting point. These guidelines estimate healthy children’s daily energy intake based on various factors. You can also refer to the Daily calorie requirements calculator by the Ministry of Health and Prevention, UAE.
- Example: A 10-year-old girl with a height of 150 cm, weight 45 kg with an active lifestyle might need around 2029 calories daily.
Macronutrients
Once we have established the calorie needs, we need to consider macronutrient breakdown. Carbohydrates and protein are vital. The Institute of Medicine sets recommended daily allowances (RDA) for these nutrients based on age and gender.
- Example: A 13-year-old boy should consume about 52 grams of protein daily.
As for fats, there’s no fixed RDA. Instead, we rely on Acceptable Macronutrient Distribution Ranges (AMDR) for balanced guidance.
- Example: Kids aged 4-18 should aim for 25-35% of their daily energy intake from fats.
You can learn more about Micronutrients vs. Macronutrients in our detailed guide.
Micronutrients
Micronutrients are mainly vitamins and minerals. Plus, most micronutrients come from fruits and vegetables. Young people are always encouraged to consume these products for optimal growth and development. If deficiencies are suspected, youngsters can also consider a multivitamin after consulting a physician.
Vitamin D is increasingly found deficient in most young kids due to extended periods of staying indoors. It is naturally formed in the body by exposure to sun and its deficiency results in weaker bones and eventually Rickets. If someone is diagnosed with a deficiency, physicians recommend tablets along with another nutritional diet.
Calcium and iron are also often deficient in active children. Dairy, fruits, vegetables, and meat can help. Vegetarian/vegan kids usually suffer from Vitamin B12 deficiency which may lead to bleeding and prolonged deficiency can lead to permanent problems with the brain and nervous system.
Refer to our article on Micronutrients which gives more insights on what they are, their importance, and major food sources and effects on their deficiencies.
Nutritional Needs For Older People
Meeting the nutritional needs of older adults is crucial for maintaining health, energy, and quality of life as they age. With changing bodies and lifestyles, their dietary requirements evolve, making balanced nutrition a key factor in supporting their overall well-being.
Hydration also goes a long way for nutritional benefits.
Energy Requirements
As people age, the daily calorie needs of the elderly decrease due to reduced activity and muscle mass. Maintaining muscle mass through activities like weight training can offset this decline. There are no set RDIs for older adults, so the BMR x activity level formula is a reasonable estimate.
- Example: A moderately active 70-year-old woman might require around 1600-1800 calories daily.
Macronutrients
Like with energy, there are no separate guidelines for macronutrient intake in older adults. Older folks should focus on a balanced diet with high-quality foods. Research suggests that 0.8g of protein per kg of body weight can maintain muscle mass in more senior “weight trainers.”
- Example: A 70-year-old man weighing 70kg might aim for 56 grams of protein daily.
Micronutrients
Micronutrients are also vital for the dietary needs of the elderly. Vitamin D and calcium are crucial for bone health in the elderly. Deficiencies of both are common, so consider supplements after consulting a healthcare provider.
- Example: A 60-year-old man may need 600 IU (15 ug) of vitamin D and 1200 mg of calcium daily.
Hydration
Aging also impacts thirst mechanisms, making older adults prone to dehydration. Proper hydration is especially crucial for those engaging in physical activities. If hypernatremia (excessive sodium levels) occurs, replace lost fluids.
- Example: Encourage older adults to drink water regularly, even if they don’t feel thirsty.
Summary
Whether young or old, balanced nutrition is fundamental for overall health and well-being. There’s no age limit on the importance of a balanced diet. A yearly check-up for micronutrient deficiency is vital to make sure that there is no deficiency. Seek medical intervention if necessary.
