Food zones is designed to help our users understand and manage their meal choices based on the nutritional content and energy density of foods. This system divides foods into different zones, typically ranging from Zone 1 to Zone 4, based on factors such as calorie content, macronutrient balance (carbohydrates, proteins, fats), fiber content, and overall nutrient density. Here's a brief overview of what each zone represents in the context of the proportions we discussed:
Zone 1 (30% of the food ):
This zone includes foods that are very low in energy density but high in nutrients. They primarily consist of non-starchy vegetables and fruits. These foods are rich in water, fiber, vitamins, and minerals, making them ideal for consuming in larger volumes to increase fullness and nutrient intake without consuming too many calories.
Zone 2 (40% of the food):
Foods in this zone are low to moderate in energy density and include whole grains, lean proteins, legumes, and low-fat dairy products. Zone 2 foods are essential for providing a balanced intake of macronutrients necessary for energy, muscle repair, and overall health, along with a variety of micronutrients.
Zone 3 (20% of the food):
This zone encompasses foods that are moderate to high in energy density. They include higher-fat foods, such as certain cuts of meat, full-fat dairy products, and some processed foods. While these foods can be part of a healthy diet, they should be consumed in moderation due to their higher calorie content and potential impact on weight and health.
Zone 4 (10% of the food):
The highest in energy density, Zone 4 includes foods that are often high in added sugars, saturated fats, and calories. This category typically comprises sweets, fried foods, and highly processed snacks. Foods in Zone 4 are considered indulgent and should be consumed sparingly as part of a balanced diet.
The food zones system aims to simplify balanced meal guidance, making it easier for users to make healthier food choices and manage their calorie intake for weight management or other health-related goals.
