How a Varied Diet Helps Meet Your Nutrient Needs

Ensuring that your body gets all the essential nutrients it needs is crucial for overall health and well-being. While supplements can help fill in gaps, there’s nothing quite like getting your nutrients from a diverse range of whole foods. A varied diet not only provides a wide array of essential vitamins and minerals but also makes meals more interesting and enjoyable.

The Importance of Variety

A varied diet refers to eating a wide range of different foods to ensure you get a diverse array of nutrients, vitamins and minerals necessary for good health. Rather than relying on just a few types of foods, a varied diet includes fruits, vegetables, whole grains, lean proteins and healthy fats from different sources. By incorporating a variety of foods into your diet, you can better meet your nutritional needs and reduce the risk of nutrient deficiencies. Every food brings its unique set of nutrients to the table. By incorporating a variety of foods into your diet, you can cover all your bases and ensure that you’re not missing out on any vital nutrients. Different colours, textures, and flavours in your meals often signify a diverse range of nutrients, so eating a rainbow of foods is a good rule of thumb. We refer to this as a ‘mixed meal’.

The importance of a mixed meal can often be overlooked, especially when someone is trying to make changes or improvements to their nutrition. A mixed meal is one that contains all three of the macronutrients; carbohydrates, protein and fat. Consuming a mixed meal will help to slow digestion, keep blood sugar levels stable and keep you feeling fuller for longer. 

RDA’s – Recommended Dietary Allowance’s

RDA’s are nutritional intake guidelines established to meet the needs of nearly all healthy individuals in a specific age and gender group. RDAs play a crucial role in ensuring adequate nutrient intake, supporting overall health, and preventing deficiencies. They are integral in designing balanced diets, informing public health policies, and guiding nutritional planning for individuals, including athletes and high-performing individuals. By adhering to RDAs, you can optimise the pillars of health, such as nutrition, exercise, and lifestyle, thereby enhancing overall well-being and performance.

Recipes for Every Need

Whether you’re a man, woman, child or athlete, there are specific nutritional requirements to consider. Let’s explore how a varied diet can meet the needs of different individuals:

For Men:

Men typically have higher calorie and protein needs than women, so their meals may focus more on lean proteins, whole grains, and plenty of fruits and vegetables.

• Meeting Calorie Needs: Men generally require more calories than women to maintain their weight and support their energy needs. Including a variety of nutrient-dense foods in their diet ensures they get enough calories to fuel their active lifestyles. Whole grains, healthy fats, and lean proteins are excellent sources of energy-rich nutrients.

• Lean Protein: is essential for muscle repair and growth, and men often have higher protein requirements than women, especially if they are physically active or engaged in intense strength training. Including lean sources of protein such as chicken, turkey, fish, lean beef, tofu, beans, and legumes in their meals helps meet their protein needs without excess saturated fat and calories.

• Whole Grains: provide complex carbohydrates, fibre, vitamins, and minerals, making them an essential part of all diets, not just for men. Incorporating a variety of whole grains such as brown rice, quinoa, oats, barley, and whole wheat bread ensures a steady supply of energy and promotes satiety. Additionally, whole grains are rich in B vitamins, which are important for energy metabolism.

• Fruits & Vegetables: are packed with vitamins, minerals, antioxidants and fibre, making them essential for overall health and well-being. Men should aim to include a variety of colorful fruits and vegetables in their meals to ensure they get a wide range of nutrients. Dark leafy greens, berries, citrus fruits, bell peppers, tomatoes, and cruciferous vegetables like broccoli and Brussels sprouts are excellent choices.

This example of a daily meal plan shows that by having a diverse, balanced diet, you can achieve almost all of the Recommended Dietary Allowances for vitamins and minerals. Carb sources include the ciabatta at breakfast, wrap at lunch and pasta at dinner. Protein comes from the eggs at breakfast, chicken at lunch, protein ball for a snack and salmon for dinner. Fat intake is spread throughout the day, in the form of pesto, mayonnaise, halloumi and salmon. 

For Women:

Women have unique nutritional needs, particularly during certain life stages such as pregnancy, lactation and menopause. Ensuring an adequate intake of key nutrients like iron and calcium is essential for women’s health and well-being. Here’s why these nutrients are important and how a varied diet can help meet women’s specific nutritional needs:

• Iron: Women of childbearing age are at a higher risk of iron deficiency due to menstruation, pregnancy and lactation. Iron requirements increase during pregnancy to support fetal growth and development. Including iron-rich foods in the diet such as lean meats, poultry, fish, beans, lentils, tofu, spinach and fortified cereals can help prevent iron deficiency anemia.

• Calcium: Calcium is essential for building and maintaining strong bones and teeth, as well as supporting muscle function and nerve transmission. Women have a higher risk of osteoporosis, a condition characterized by weak and brittle bones, especially after menopause when oestrogen levels decline. Consuming an adequate amount of calcium-rich foods such as dairy products, fortified plant-based milk, leafy greens (e.g., kale), tofu, almonds, and canned fish with bones can help maintain bone health and reduce the risk of osteoporosis.

• Other Essential Nutrients: Folate is essential for preventing neural tube defects during pregnancy, so women of childbearing age should consume folate-rich foods such as leafy greens, citrus fruits, beans, and fortified grains, or supplement with folic acid if necessary. Omega-3 fatty acids, found in fatty fish like salmon and trout, are important for heart health.

For Children:

Children have unique nutritional needs that are essential for supporting their growth, development, and overall health. A balanced diet that includes a variety of nutrient-rich foods is crucial for fueling their active lifestyles and promoting proper growth. Here’s why each nutrient is important and how they contribute to children’s health:

• Carbohydrates: are the body’s primary source of energy, especially for active children who are constantly on the move. Whole grains, fruits, vegetables and legumes provide complex carbohydrates, fibre, vitamins and minerals that support sustained energy levels and promote satiety. Including a variety of carbohydrate-rich foods in children’s meals helps fuel their activities and supports their growing bodies.

• Protein: Children need adequate protein to support their rapid growth and development, especially during infancy, childhood and adolescence. Good sources of protein include lean meats, poultry, fish, eggs, dairy products, tofu, beans and legumes. Including a variety of protein-rich foods in children’s meals helps ensure they get all the essential amino acids they need for optimal growth and development. Essential amino acids are those thaat must be obtained from the diet, as they can’t be made in the body. 

• Healthy Fats: are important for satiety, brain development, hormone production and absorption of fat-soluble vitamins (A, D, E & K). Including sources of healthy fats such as avocados, nuts, seeds, olive oil and fatty fish (e.g., salmon, sardines) in children’s meals supports cognitive function and promotes overall health. Limiting saturated and trans fats found in processed and fried foods helps maintain heart health and reduce the risk of obesity and chronic diseases later in life. 

• Vitamins & Minerals: play a crucial role in supporting various physiological functions, including immune function, bone health and energy metabolism. Children need a wide range of vitamins and minerals to support their growth and development. Encouraging children to eat a variety of colorful fruits and vegetables ensures they get a broad spectrum of vitamins (e.g., vitamin C, vitamin A, folate) and minerals (e.g., calcium, iron, zinc) essential for their health.

For Athletes:

Athletes have increased energy and nutrient needs to support their training and performance. A varied diet rich in carbohydrates for energy, protein for muscle repair, and antioxidants for  recovery is essential for optimizing athletic performance. When it comes to athletic performance, nutrition also plays a crucial role. Proper fueling before, during and after exercise can significantly impact an athlete’s energy levels, endurance and recovery. 

Here’s how a varied diet can optimize performance:

• Energy: Carbohydrates are the body’s primary source of fuel during exercise. Incorporating a variety of whole grains, fruits, and vegetables into your diet ensures a steady supply of carbohydrates to fuel physical activity. 

• Muscle Repair & Growth: Protein is essential for repairing and building muscle tissue, which is crucial for athletes looking to improve performance and recover from intense training sessions. Including a variety of protein sources such as lean meats, fish, eggs, dairy, legumes and plant-based proteins ensures that you’re getting all the essential amino acids your body needs.

• Hydration: is essential for maintaining optimal performance and preventing dehydration. Did you know, as little as 2% dehydration can have an impact on your performance? Along with water, electrolytes such as sodium, potassium and magnesium, particularly for heavy/salty sweaters, play a key role in fluid balance and muscle function. Including a variety of hydrating foods such as fruits and vegetables, can help replenish electrolytes lost through sweat.

• Nutrient Timing: Timing your meals and snacks around workouts can enhance performance and recovery. Consuming a balanced meal or snack containing carbohydrates and protein 1-2 hours before exercise provides energy and primes your muscles for activity. After exercise, refueling with a combination of carbohydrates and protein helps replenish glycogen (energy in muscle) stores and promotes muscle repair and growth.
