Nutrition is the intake of food, considered in relation to the body’s dietary needs. Good nutrition – an adequate, well balanced diet combined with regular physical activity – is a cornerstone of good health. Poor nutrition can lead to reduced immunity, increased susceptibility to disease, impaired physical and mental development, and reduced productivity.
Good nutrition provides nutrient density.Good nutrition controls energy balance.Good nutrition achieves health, body composition, and performance goals.Good nutrition is honest and outcome-based.Good nutrition is sustainable.
When it comes to good nutrition, we look at food in two different ways: 1) Nutrient Density and 2) Calorie Density.
Nutrient Density is the ratio of nutrients (like vitamins, minerals, fibre, etc) relative to the calorie (energy) content in a food. A food with high nutrient density would be rich in key nutrients per 100 calories of food. A food with a low nutrient density would contain very few nutrients per 100 calories of food.
Calorie Density is the ratio of calories (which are units of potential energy stored in food) to the weight of a food. A food with a high-calorie density would contain a high amount of calories (energy) per 100 grams of food. A food with a low-calorie density would containvery few calories (energy) per 100 grams of food.
The Best Combination:
The best combination (for most people) for improving health and promoting fat loss is a diet that is higher in nutrient-dense foods and lower in calorie-dense foods.
