Categorising foods as good or bad is a sure shot way to sabotage ones weight management goals. Within the right context, all foods can be a part of daily nutrition. However, it's important to have some defined ways to include food, when one is working towards a specific goal.
In comes - FOOD COLOUR CODING. This is an intelligent and logical way to know the foods we eat a little better, based on how dense they are with calories. This makes it convenient to navigate the entire day without feeling too full or too starved. Food items are colour-coded based on their calorie density. Calorie density is the total calories per gram of food
If the number of calories per gram of food is high, it will be coloured as a RED FOOD.
If the number of calories per gram of food is moderate, it will be coloured as a YELLOW FOOD.
If the number of calories per gram of food is low, it will be coloured as a BLUE FOOD
The color code of a food is not an indicator of whether a food is good or bad. It simply implies the food is dense in calories. There are many nutrient dense foods that might be categorized as Red Foods and many nutrient hollow foods that might be categorized as Blue foods.
Good or bad is decided by a lot of context and goal for which the food is being eaten. A lot of hyper-palatable foods are red-colored. That means the possibility of over-consuming these foods is high.
You would also end up consuming more calories by consuming smaller quantities of red foods. This could trigger hunger and kill satiety across the day coming in the way if your goal is fat-loss.
