Eating a healthy and balanced diet is important for people of all ages, as it gives them the nutrients their bodies need to function and grow. Nutritional needs change as people age, and adults may need to adjust their diets to ensure they are getting the right amount of nutrients. For example, while adults may need fewer calories as they age, they still need to consume enough nutrients. A healthy diet can help prevent diseases such as osteoporosis, high blood pressure, heart disease, type 2 diabetes, and certain cancers. It is recommended that adults eat at least five portions of fruits and vegetables every day, as well as consume foods from other food groups such as dairy, protein, and healthy fats.

What You'll Learn
Eat more fruit and vegetables
Eating a balanced diet is essential for maintaining a healthy body weight. While the specific nutritional needs of each person vary depending on their age, sex, and physical activity level, there are some general guidelines that apply to adults.
One key component of a balanced diet is consuming a variety of fruits and vegetables. Fruits and vegetables are packed with vitamins, minerals, and fiber, which provide numerous health benefits. For instance, they are a good source of vitamins A, C, and E, as well as magnesium, zinc, phosphorus, and folic acid. Consuming adequate amounts of these nutrients can help lower the risk of heart disease, stroke, and certain types of cancer. Additionally, the fiber content in fruits and vegetables aids in digestion and can help prevent constipation.
Fruits and vegetables are also naturally low in calories, fat, saturated fat, salt, and sugar, making them an excellent choice for weight management. They can help you feel full without consuming excess calories, which is beneficial if you are trying to lose weight or maintain a healthy weight. Furthermore, the high water content in many fruits and vegetables can also contribute to hydration, which is an important aspect of a healthy diet.
To incorporate more fruits and vegetables into your diet, try adding a side salad to your lunch or having a portion of vegetables with dinner. Fresh, frozen, canned, dried, or juiced produce can all contribute to your daily intake. Aim for at least five portions of a variety of fruits and vegetables each day to reap the full range of health benefits that they offer.

Choose nutrient-dense proteins
A balanced diet is key to maintaining a healthy body weight. It involves eating a wide variety of foods in the right proportions. Nutrient-dense proteins are an essential part of this.
Protein is a building block of the body, making up bones, cartilage, muscle, blood, skin, enzymes, hormones, and vitamins. It is made up of amino acids, some of which our bodies can produce, while others must be obtained from food. These are called essential amino acids.
Animal sources of protein, such as meat, eggs, and dairy, are complete proteins, meaning they contain all the essential amino acids. Lean meats, such as chicken, turkey, beef, and pork, are excellent sources of high-quality protein and nutrients like iron and zinc. Eggs, considered "nature's multivitamin," are particularly nutritious in the yolk, which contains vitamins, minerals, and antioxidants beneficial for eye health. Dairy products like milk, cheese, and yogurt are also rich in protein and other essential nutrients like calcium. However, they can be high in saturated fat, so opting for low-fat or fat-free alternatives is recommended.
For plant-based proteins, beans, peas, lentils, nuts, seeds, and soy products are excellent options. They provide protein and other nutrients like fiber, folate, potassium, and healthy fats. Quinoa is another plant-based complete protein source, offering about 8 grams of protein and 5 grams of fiber per cooked cup. Soy products like tofu and tempeh are also good sources of protein, with a quarter cup of tofu providing 7 grams of protein. Plant sources of protein tend to be lower in saturated fat and cholesterol and higher in fiber and other beneficial nutrients. However, plant-based meat alternatives can be highly processed and high in sodium.
Seafood is another nutrient-dense protein option. It not only provides protein but also contains omega-3 fatty acids like EPA and DHA, which promote heart health. The Dietary Guidelines recommend including a variety of seafood in your diet, with a weekly intake of 8 to 10 ounces.

Consume dairy or alternatives
Dairy products are a good source of protein, calcium, iodine, vitamin A, vitamin D, riboflavin, vitamin B12, and zinc. These nutrients are important for maintaining strong and healthy bones, as well as for muscle health, heart health, and blood clotting. However, dairy products can be high in saturated fat, so it is recommended to opt for lower-fat or fat-free alternatives. For example, choosing skimmed or 1% fat milk can help reduce saturated fat intake while still providing the nutritional benefits of milk.
For those who are unable or choose not to consume dairy, there are various alternatives available. These include plant-based milk alternatives such as soy, rice, oat, almond, hazelnut, coconut, quinoa, and potato drinks, often referred to as "milks." While these alternatives may not have the same nutritional profile as dairy milk, some are fortified with calcium and other nutrients. It is worth noting that the amount of calcium that can be absorbed from these fortified products may vary. Additionally, there are non-dairy, vegan-friendly products that have added calcium to ensure adequate intake.
When it comes to yogurt, there are also dairy-free options such as soy and coconut-based yogurts. These alternatives can be a good source of calcium and provide similar health benefits to dairy yogurt. For cheese lovers, there are vegan alternatives made from a variety of bases, including soy, almonds, and cashews. These alternatives can be used in cooking or as toppings, providing a similar taste and texture to their dairy counterparts.
It is important to note that while dairy alternatives offer choices for those with dietary restrictions or preferences, the nutritional content can vary significantly. Some alternatives may be highly processed and contain added sugars or sodium. Therefore, it is essential to read labels and choose products that align with your nutritional needs and preferences. Additionally, consulting a dietitian or healthcare professional can provide personalized guidance on incorporating dairy or alternatives into your diet to ensure adequate nutrient intake.

Limit unhealthy fats, sugars, and calories
A healthy diet for adults involves limiting unhealthy fats, sugars, and calories. This means reducing the consumption of saturated fats, trans fats, and added sugars, which can lead to weight gain and chronic health issues.
Firstly, it is important to limit saturated fats, which are mainly found in animal products such as fatty meats, butter, and cheese. These "bad" fats can increase the risk of heart disease and should make up less than 10% of daily calorie intake. Instead, opt for polyunsaturated and monounsaturated fats, found in vegetable oils and nuts, which are "good" fats that promote heart health.
Secondly, trans fats, often found in partially hydrogenated vegetable oils and processed foods, should be avoided. These fats have been linked to an increased risk of heart disease, and the U.S. Food and Drug Administration (FDA) has taken steps to remove them from the food supply.
Thirdly, added sugars, which are commonly found in sweetened beverages, snacks, and processed foods, provide extra calories without any nutritional benefits. These sugars can lead to weight gain and are particularly prevalent in the diets of children, adolescents, and young adults. It is recommended that less than 10% of daily calories come from added sugars. To reduce intake, opt for water or low-sugar alternatives, limit sweet snacks, and choose unsweetened versions of canned fruit, yogurt, and other products.
Additionally, it is important to be mindful of total calorie intake. While oils are a healthy source of nutrients, they are high in calories, so portion sizes should be considered. For older adults, the recommended daily allowance of oils ranges from 5 to 8 teaspoons, depending on activity levels.
Finally, when it comes to starchy foods, choose wholegrain or wholemeal varieties such as brown rice, wholewheat pasta, and wholemeal bread. These provide more fibre and nutrients than their refined counterparts.

Drink plenty of fluids
Water is an essential nutrient that supports vital bodily functions. It is important to drink plenty of fluids to stay hydrated and maintain good health. The body is composed of about 60% water, and adequate fluid intake helps the body's cells to function properly.
The amount of water a person needs varies depending on factors such as age, sex, activity level, and overall health. On average, it is recommended that adults consume at least 6-8 glasses of water or other fluids per day. This amount can be adjusted based on individual needs and activity levels. For example, older adults may need to adjust their fluid intake due to changes in their sense of thirst or other health considerations.
It is important to note that all beverages, including tea, coffee, and fruit juices, contribute to daily fluid intake. However, water is the best source of hydration as it is calorie-free and does not contain added sugars or other additives. Drinking water is especially important when consuming foods with high salt content to prevent dehydration. Additionally, water can be infused with slices of lemon, lime, or orange to add flavour and variety.
Dehydration occurs when the body loses more fluids than it takes in, and it can have negative effects on health. Signs of dehydration include feeling thirsty, having a dry mouth, producing less urine, and experiencing dizziness or lightheadedness. It is important to drink plenty of fluids to prevent dehydration and maintain optimal health. Staying hydrated supports the body's systems, including digestion, circulation, and temperature regulation.
