Nutrition Guide
Comprehensive information about nutrition, macronutrients, and maintaining a balanced diet for optimal health.
Understanding the Basics of Nutrition
Good nutrition is essential for maintaining health and wellbeing. Understanding the basics can help you make better food choices.
Nutrition is the science that interprets the relationship between food and its impact on the body's function. Good nutrition means your body gets all the nutrients, vitamins, and minerals it needs to work at its best.
A balanced diet provides your body with the nutrients it needs to function correctly. To get the proper nutrition from your diet, you should consume the majority of your daily calories from:
- Fresh fruits and vegetables
- Whole grains
- Lean proteins
- Healthy fats
- Dairy or dairy alternatives
The food you eat can affect your health and your risk for certain diseases. To maintain your health, you need to eat foods that nourish your body. Using our Food Calorie Calculator can help you understand the nutritional content of your meals and make informed dietary choices.
Understanding Macronutrients
Proteins
Proteins are essential nutrients for building and repairing tissues, making enzymes and hormones, and supporting immune function. They're made up of amino acids, the building blocks of protein.
Good Sources:
- • Lean meats and poultry
- • Fish and seafood
- • Eggs
- • Dairy products
- • Legumes and beans
- • Tofu and tempeh
- • Nuts and seeds
Carbohydrates
Carbohydrates are your body's main source of energy. They fuel your brain, kidneys, heart muscles, and central nervous system. Complex carbs are healthier as they take longer to digest and provide more nutrients.
Good Sources:
- • Whole grains
- • Fruits
- • Vegetables
- • Legumes
- • Quinoa
- • Brown rice
- • Sweet potatoes
Fats
Fats are essential for energy, cell growth, hormone production, absorption of certain vitamins, and keeping your body warm. Healthy fats, like mono and polyunsaturated fats, are important for heart health.
Good Sources:
- • Avocados
- • Olive oil
- • Nuts and seeds
- • Fatty fish (salmon, mackerel)
- • Chia and flax seeds
- • Eggs
- • Dark chocolate
Understanding Micronutrients
Micronutrients are the vitamins and minerals required in small amounts that are essential for the development, disease prevention, and wellbeing. Although needed in smaller quantities than macronutrients, micronutrients are vital for health.
Essential Vitamins
-
Vitamin A:
Important for vision, immune function, and cell growth. Found in sweet potatoes, carrots, spinach, and liver.
-
Vitamin C:
Necessary for the growth and repair of tissues. Found in citrus fruits, strawberries, kiwi, and bell peppers.
-
Vitamin D:
Essential for bone health and immune function. Produced by skin when exposed to sunlight; also found in fatty fish and fortified foods.
-
Vitamin E:
Acts as an antioxidant in the body. Found in nuts, seeds, and vegetable oils.
-
B Vitamins:
Important for energy production, brain function, and cell metabolism. Found in whole grains, meat, eggs, and leafy greens.
Essential Minerals
-
Calcium:
Essential for bone health, muscle function, and nerve transmission. Found in dairy products, leafy greens, and fortified foods.
-
Iron:
Necessary for the formation of hemoglobin and oxygen transport. Found in red meat, beans, spinach, and fortified cereals.
-
Magnesium:
Important for muscle and nerve function, blood glucose control, and blood pressure regulation. Found in nuts, seeds, whole grains, and green leafy vegetables.
-
Zinc:
Essential for immune function, protein synthesis, and wound healing. Found in oysters, meat, poultry, beans, and nuts.
-
Potassium:
Helps regulate fluid balance, muscle contractions, and nerve signals. Found in bananas, potatoes, spinach, and yogurt.
To ensure you're getting adequate micronutrients, aim for a varied diet with plenty of colorful fruits and vegetables. Tracking your food intake with our Food Calorie Calculator can help you identify potential nutrient gaps in your diet.
Balanced Diet Guidelines
The Plate Method
Plate
The plate method is a simple way to ensure you're getting a balanced meal. Here's how to build your plate:
- 50% Vegetables and Fruits: Fill half your plate with non-starchy vegetables and fruits.
- 25% Proteins: Dedicate a quarter of your plate to protein-rich foods.
- 25% Whole Grains/Starches: Fill the remaining quarter with whole grains or starchy vegetables.
- Healthy Fats: Include a small amount of healthy fats with your meal.
This method ensures you get a good balance of nutrients without having to measure or weigh your food. It's a practical approach to portion control and balanced eating.

These guidelines are general recommendations. Individual needs may vary based on factors like age, gender, activity level, and specific health conditions. Use our Food Calorie Calculator to get a better understanding of your personal nutritional needs.
Special Dietary Considerations
Vegetarian & Vegan Diets
Plant-based diets can be nutritionally complete when planned properly. Key nutrients to focus on include:
- • Protein: Legumes, tofu, tempeh, seitan, nuts, and seeds.
- • Vitamin B12: Fortified foods or supplements (especially for vegans).
- • Iron: Legumes, tofu, tempeh, spinach, and fortified foods.
- • Calcium: Fortified plant milks, tofu made with calcium sulfate, leafy greens.
- • Omega-3 fatty acids: Flaxseeds, chia seeds, walnuts, or algae-based supplements.
Use our Food Calorie Calculator to ensure you're meeting your nutritional needs on a plant-based diet.
Gluten-Free Diet
Required for those with celiac disease or gluten sensitivity, a gluten-free diet eliminates wheat, barley, and rye. Focus on naturally gluten-free foods:
- • Gluten-free grains: Rice, quinoa, millet, buckwheat, and certified gluten-free oats.
- • Fruits and vegetables: All fresh produce is naturally gluten-free.
- • Proteins: Meat, fish, eggs, legumes, nuts, and seeds.
- • Dairy: Most dairy products are naturally gluten-free.
Be vigilant about cross-contamination and hidden sources of gluten in processed foods. Our Food Scanner can help identify potential gluten-containing ingredients.
Low-Carb & Ketogenic Diets
These diets restrict carbohydrate intake to varying degrees. A ketogenic diet typically limits carbs to 20-50g per day. Focus on:
- • Healthy fats: Avocados, olive oil, coconut oil, nuts, and seeds.
- • Proteins: Meat, fish, eggs, and some dairy products.
- • Low-carb vegetables: Leafy greens, broccoli, cauliflower, peppers, and zucchini.
- • Limited fruits: Small amounts of berries are typically allowed.
Track your macronutrient intake carefully with our Food Calorie Calculator to ensure you're staying within your carb limits.
Mediterranean Diet
This heart-healthy eating pattern is based on traditional foods from Mediterranean countries. Key components include:
- • Plant foods: Fruits, vegetables, whole grains, legumes, and nuts.
- • Olive oil: The primary source of added fat.
- • Fish and seafood: Eaten at least twice per week.
- • Moderate dairy, eggs, and poultry: Consumed in smaller amounts.
- • Limited red meat: Eaten infrequently and in small portions.
This diet has been linked to numerous health benefits, including reduced risk of heart disease and certain cancers.
