Nutrition During the adult years **Nutritional Needs** By the time you reach adulthood, 19-50, the majority of your growth and development will be complete. This means your focus, with regards to nutritional needs, can now shift to maintaining a healthy and active lifestyle and preventing **diet-related health problems**, such as cardiovascular disease, hypertension and type 2 diabetes. **Adult Nutrition-Related Concerns** For adults, weight management can be a major nutrition-related concern and a key factor in achieving health and wellness. In order to remain healthy, adults must be aware of changes in their energy needs, based on their level of physical activity, and then balance their calorie intake as needed. Adults who are active in sports or other physical activities may require more calories than adults who are less active. **Dietary Recommendations for Adults** Caloric intake for adult women should be 1,800 to 2,200 calories a day and adult men should consume 2,200 to 2,800 calories depending on age and activity level. It is recommended that adults consume anywhere from 45%-65% carbohydrates, 10%-35% protein and 20%-35% of total fat, while saturated fat should be less than 10% of daily calories. You should avoid trans fats when possible, while choosing healthier fats, such as monounsaturated and polyunsaturated. Foods that include these types of fats would be nuts, seeds, fish and vegetable oils. Cholesterol intake should be less than 300 mg percent. With the onset of adulthood, good nutrition can help young adults enjoy an active lifestyle. For most people, young adulthood (ages 19-30) is the time when their bodies are in the best condition. The body of an adult does not need to devote its energy and resources to support the rapid growth and development that characterizes youth. However, the choices made during those formative years can have a lasting impact. Eating habits and preferences developed during childhood and adolescence influence health and fitness into adulthood. Adults must monitor their dietary decisions and make sure their caloric intake provides the energy that they require, without going into excess. During this stage, growth is completed and people reach their physical peak. Major organs and body systems have fully matured by this stage of the life cycle. In order to maintain health and fitness at this age, it is important to continue to practice good nutrition. Healthy eating habits promote metabolic functioning, assist repair and regeneration, and prevent the development of chronic conditions. **Energy** Young men typically have higher nutrient needs than young women. For ages 19-30, typical energy requirements for women are 1,800-2,400 calories, and 2,400-3,000 calories for men, depending on activity level. These estimates do not include women who are pregnant or breastfeeding, who require a higher energy intake **Macronutrients** The Acceptable Macronutrient Distribution Ranges (AMDRs) for 19-30 year olds.For carbohydrates, the AMDR is 45-65% of daily calories. All adults, young and old, should eat fewer energy-dense carbohydrates, especially refined, sugar-dense sources, particularly for those who lead a more sedentary lifestyle. The AMDR for fiber is 25 grams per day for women and 38 grams per day for men. Soluble fiber may help improve cholesterol and blood sugar levels, while insoluble fiber can help prevent constipation. The AMDR for protein is 10-35% of total daily calories, and should include a variety of lean meat and poultry, eggs, beans, peas, nuts, and seeds. It is also important to replace proteins that are high in saturated fat with ones that are lower in solid fats and calories. All adults should limit total fat to 20-35% of their daily calories and keep saturated fatty acids to less than 10% of total calories by replacing them with monounsaturated and polyunsaturated fatty acids **Macronutrient AMDR** Carbohydrate 45-65% of total calories Protein 10-35% of total calories Fat 20-35% of total calories **Micronutrients** Micronutrient needs in adults differ slightly according to sex. Males require more of vitamins C and K, along with thiamin, riboflavin, and niacin. Females require extra iron due to menstruation. micronutrient recommendations for young adult men and women. +-----------------------+-----------------------+-----------------------+ | **Nutrient** | **Young Adult Males** | **Young Adult | | | | Females** | +=======================+=======================+=======================+ | Vitamin A (mcg) | 900 | 700 | +-----------------------+-----------------------+-----------------------+ | Vitamin B~6~ (mg) | 1.3 | 1.3 | +-----------------------+-----------------------+-----------------------+ | Vitamin B~12~ (mcg) | 2.4 | 2.4 | +-----------------------+-----------------------+-----------------------+ | Vitamin C (mg) | 90 | 75 | +-----------------------+-----------------------+-----------------------+ | Vitamin D | 15 | 15 | | | | | |  (mcg) | | | +-----------------------+-----------------------+-----------------------+ | Vitamin E (mg) | 15 | 15 | +-----------------------+-----------------------+-----------------------+ | Vitamin K | 120 | 90 | | | | | |  (mcg) | | | +-----------------------+-----------------------+-----------------------+ | Calcium | 1,000 | 1,000 | | | | | |  (mg) | | | +-----------------------+-----------------------+-----------------------+ | Folate (mcg) | 400 | 400 | +-----------------------+-----------------------+-----------------------+ | Iron (mg) | 8 | 18 | +-----------------------+-----------------------+-----------------------+ | Magnesium | 400 | 310 | | | | | |  (mg) | | | +-----------------------+-----------------------+-----------------------+ | Niacin (B~3~) (mg) | 16 | 14 | +-----------------------+-----------------------+-----------------------+ | Phosphorus | 700 | 700 | | | | | |  (mg) | | | +-----------------------+-----------------------+-----------------------+ | Riboflavin (B~2~) | 1.3 | 1.1 | | (mg) | | | +-----------------------+-----------------------+-----------------------+ | Selenium (mcg) | 55 | 55 | +-----------------------+-----------------------+-----------------------+ | Thiamin (B~1~) (mg) | 1.2 | 1.1 | +-----------------------+-----------------------+-----------------------+ | **Zinc (mg)** | **11** | **8** | +-----------------------+-----------------------+-----------------------+ **Nutritional Guidelines** **Macronutrients** 1. **Carbohydrates**: 45-65% of total daily calories - Focus on whole grains, fruits, and vegetables. - Limit added sugars. 2. **Proteins**: 10-35% of total daily calories - Include lean meats, poultry, fish, beans, nuts, and dairy. - Aim for 46-56 grams per day, depending on activity level and age. 3. **Fats**: 20-35% of total daily calories - Prioritize healthy fats like avocados, nuts, seeds, and olive oil. - Limit saturated fats and trans fats. **Micronutrients** - **Vitamins and Minerals**: Ensure a variety of fruits and vegetables to meet daily needs. - Important ones include calcium, potassium, iron, and vitamins A, C, D, and B12. **Hydration** - Drink plenty of water; about 2.7 liters (91 ounces) for women and 3.7 liters (125 ounces) for men, including all beverages and food sources. **Dietary Fiber** - Aim for 25 grams per day for women and 38 grams for men. - Sources: fruits, vegetables, whole grains, and legumes. **Limitations** - Reduce sodium intake to less than 2,300 mg per day. - Limit added sugars to less than 10% of total daily calories. **Physical Activity** - Engage in at least 150 minutes of moderate aerobic activity or 75 minutes of vigorous activity per week, along with muscle-strengthening activities on two or more days. **Moderation and Variety** - Emphasize a balanced diet with a variety of foods to ensure adequate nutrient intake. Always consider individual health needs, lifestyle, and preferences, and consult with a healthcare provider or nutritionist for personalized guidance! 4o mini **Nutritional Concerns in Young Adulthood** There are a number of intake recommendations for young adults. According to the IOM, an  Adequate Intake (AI) of fluids for men is 3.7 liters per day, from both food and liquids. The AI for women is 2.7 liters per day, from food and liquids.^1^ It is best when fluid intake is from water, instead of sugary beverages, such as soda. Fresh fruits and vegetables, including watermelon and cucumbers, are excellent food sources of fluid. In addition, young adults should avoid consuming excessive amounts of sodium. The health consequences of high sodium intake include high blood pressure and its complications. Therefore, it is best to limit sodium to less than 1,500 milligrams per day. ^Physiological\ changes\ :^ **^1.\ Musculoskeletal\ System^** - ^**Bone\ Density:**\ Decreases\ with\ age,\ increasing\ the\ risk\ of\ fractures\ and\ osteoporosis.^ - ^**Muscle\ Mass:**\ Sarcopenia\ leads\ to\ a\ decline\ in\ muscle\ mass\ and\ strength.^ **^2.\ Cardiovascular\ System^** - ^**Heart:**\ The\ heart\ may\ become\ less\ efficient,\ with\ a\ decrease\ in\ maximum\ heart\ rate.^ - ^**Blood\ Vessels:**\ Stiffening\ of\ arteries\ can\ lead\ to\ increased\ blood\ pressure.^ ^**Metabolism**:^ ^Metabolic\ rate\ generally\ declines,\ which\ can\ contribute\ to\ weight\ gain\ if\ dietary\ habits\ remain\ unchanged.^ **^3.\ Respiratory\ System^** - ^**Lung\ Function:**\ Decreased\ lung\ elasticity\ and\ capacity,\ making\ breathing\ less\ efficient.^ **4.
