From infancy to senior years, understanding the unique nutritional needs at the different stages of your life is essential for maintaining health and wellness. Here’s a closer look at how nutritional needs vary by age and how to tailor diets accordingly.
Infants and toddlers: building blocks for a healthy diet
Infants have unique nutritional needs that set the stage for lifelong health. Jenny Walker, a neonatal dietitian at OhioHealth, explains, “It’s recommended by the American Academy of Pediatrics that all infants get supplemental vitamin D. Vitamin D, calcium and phosphorous all help to build strong bones.”
Walker also stresses that a healthy iron intake is vital for brain development. The iron content of breast milk is lower than the iron content of baby formula, so breastfed babies may require supplemental iron. Parents should work with their pediatrician if considering adding supplements to the baby’s diet outside of those already included in fortified baby formula.
As babies transition into eating soft and solid foods around the age of one, calcium, phosphorous and vitamin D continue to be important for bone health. In addition, proteins — the building blocks of our tissues — start to become more important in young children’s diets. “Toddlers’ diets tend to be very carbohydrate heavy simply based on what kids like to eat,” says Walker. “It’s more difficult to get kids to eat protein. Try to focus on providing a balanced plate so your toddler is getting a variety of fruits and vegetables, and a healthy balance of carbs and proteins.”
Variety in a toddler’s diet becomes key. You are introducing a lot of new foods, and your toddler is starting to form opinions about them. It’s important to remember that you may have to introduce foods multiple times to your child before they accept it, Walker advises. Re-introducing foods in different ways can also help with this. For example, your toddler might not like raw carrots but could like them roasted. Repetition with foods will provide a higher rate of acceptance.
Crystal Ward, lead clinical dietitian at OhioHealth, suggests that finger foods can also encourage young children to explore new foods.
This period is often instrumental in establishing your kid’s relationship with food and creating healthy eating habits. Here are some tips for parents to help avoid picky eating from an early age:
- Model the food behaviors you want to see from your children. They can’t be expected to be open to trying new foods if their parents won’t eat them.
- Incorporate healthy foods kids are reluctant to try into other foods they already like. For example, you can add vegetables into soups, casseroles or sauces.
- Start including kids in the meal prep experience in age-appropriate ways. This can encourage kids to be more open to trying new things.
- Make mealtime a pleasant experience. Stick to kid-appropriate portions and avoid forcing a child to eat more than they can. Also, avoid using food as a reward or punishment.
Children and teenagers: fueling growth and development
Lifelong eating habits are often developed between the ages of five and 11 and are greatly influenced by family, friends and the media. Young children may be averse to trying new foods and often do not have enough protein, milk or vegetables in their diet. Children without a balanced diet are at risk for vitamin A, zinc, iron and calcium deficiencies, all of which are important for continued bone and muscle development. If you have any concerns about insufficient balances in your kid’s diet, talk to your pediatrician about adding a multivitamin supplement.
Puberty brings the second-highest nutrient and caloric needs after infancy. A key time for bone development is between the ages of 10-20 years old. It’s important for teens to have an adequate intake of calcium and vitamin D. “Calcium doesn’t just have to come from milk,” says Ward. “Cheese, yogurt, broccoli, spinach, kale, tofu, almond milk and more all have calcium.”
At this age, kids are getting involved in more activities and some teens will start working, often making a nutritious diet harder to maintain. Ward recommends keeping hearty, portable snacks like apples with peanut butter or cheese sticks available. Meal prepping with easy, healthy crockpot or instant pot meals also helps avoid resorting to fast food when schedules start filling up.
Body image and nutrition can also intersect during these years. Ward suggests focusing on positive messaging: “Talk about how you can help provide adequate energy and help kids succeed through their diet rather than weight loss. Promote a healthy relationship with food by making it about what they can gain, like energy and strength.”
Adults: balancing energy, nutrients and portions
As metabolism slows in your 30s and 40s, portion control becomes increasingly important. Take time to refine portion sizes and align energy intake with your body’s needs to prevent middle-age weight gain. To help you figure out your ideal portion sizes, Ward suggests the balanced plate method. “If you’re using a 9-inch dinner plate, the recommended portions are that a quarter of your plate is you protein source, half the plate is a non-starchy vegetable like leafy greens, broccoli or other cruciferous vegetables, and a quarter of your plate is your starch like whole grain rice, potatoes or corn,” say Ward. If you’re interested in cutting back your portion sizes, you can use this same method with a smaller diameter plate.
Like in other stages of life, adults should still prioritize adequate intakes of protein, vegetables and vitamin D, while limiting sugars and processed foods. They should also start transitioning to more lean proteins like chicken and turkey and incorporating more whole grains and healthy fats like avocados, nuts and olive oil. During their childbearing years, women should also make sure they are getting enough iron in their diet.
Nutrition can impact mental health as well. A balanced diet rich in complex carbohydrates and lean proteins can sustain energy levels and improve your mood. “Food is energy,” says Ward. “A balanced diet provides sustained energy compared to the quick burst you get from sugary snacks.”
Seniors: prioritizing nutrition through life changes
As people age, nutritional needs change due to decreased appetite, reduced mobility, and health conditions. Practical solutions like pre-chopped vegetables or meal delivery services can make healthy eating more manageable for seniors with mobility or energy limitations. Saliva production also decreases over time, making it more difficult to eat drier foods like meats.
Calcium-rich foods, such as canned salmon or fortified plant-based milks, support bone health. Other sources of proteins like eggs, canned tuna, Greek yogurt and cheese can be great nutritional additions to seniors’ diets.
Seniors often face deficiencies in vitamins B12 and D, which are critical for bone and neurological health, due to a naturally lower absorption rate of B12 and reduced sun exposure. Often, seniors need to start taking supplements to ensure they are getting a heathy number of vitamins and minerals. Some supplements and foods can interact with common medications, making it important to consult with your care provider first.
If providing healthy meals for yourself ever starts to become difficult due to mobility or other life circumstances, Ward emphasizes that seniors should ask their primary care providers for help. She recognizes that sometimes, this can be a difficult time to transition into new eating habits. Thankfully there are assistance programs, new cooking tools and adaptations that are easy to adopt for people looking to prioritize their nutrition.
Re-evaluating your diet
Nutritional needs aren’t static. Life changes, like pregnancy, illness, or aging, require periodic reassessment of dietary habits. In the early stages of life, up to the age of two, parents should consider re-evaluating their kids’ diets about every three months to make sure they are getting all the nutrients they need. Adults, however, may only need to check in once every decade to ensure their diet is meeting their needs.
Consulting with a dietitian or healthcare provider can help ensure your diet continues to meet your health goals. By adapting your diet to meet the needs of each stage of life, you can support your body’s changing requirements and promote long-term health.
