The difference between nutrient dense and nutrient “empty” foods.
I’m pretty sure you will have heard somewhere down the line someone say something along the lines of “You’re just eating empty calories” but do you know what they actually meant by it? Did they know what they meant?
All foods contain marco-nutrients which we spoke about in Day 6 – proteins, carbohydrates, and fats, in varying proportions. Not all foods contain micro-nutrients.
A micro-nutrient is a chemical element or substance required in trace amounts for the normal growth and development of living organisms. Think vitamins and minerals.
Generally speaking we, as humans, cannot produce vitamins and minerals and so we must obtain them from plant and animal sources. When you eat you consume the vitamins that plants and animals have created and minerals they have absorbed. The micro-nutrient content of each food is different. By eating a variety of foods you are increasing the number of different micro-nutrients available to your body.
So, this should give you a good idea of where we are going with what is considered nutrient dense and what is not….
Let’s start with nutrient dense foods – non-processed plant and animal products/food stuffs in their more natural state. Think organic fruit and veg, fresh butchered meats, fresh fish, whole grains, pulses and legumes and so on.
The “empty” calorie, low nutrient density foods are things that are highly processed and very refined. Think white sugar and bread, highly processed foods, long-life foods etc. Fast food, junk food and so on. They are generally high calorie foods.
Why is this important?
Your body needs a wide variety of vitamins and minerals in order to function properly, here’s a list of just some of them and what they do:
By eating a wide variety of nutrient dense foods (like the ones listed above) you create satiety – feeling well fed, not lacking in anything. IF you are eating a whole load of empty food you are taking in all the calories without giving the body what it actually needs, you get hungry again because the body is trying to get what it needs and then you are over-eating and putting on weight, not to mention the risks of feeling wick because your body hasn’t got the fuel it needs to function correctly.
This is why we have the 80:20 rule. By eating well 80% of the time you will more than likely be hitting all of the macro and micro-nutrient needs of your body. Giving you 20% of you calories to the stuff you like; the “empty” calories, or the shit that we all enjoy basically.
