There are 6 Nutrients that you can't survive without
Protein, Carbohydrates, Fats, Vitamins, Minerals, Water
A protein is an energy-providing nutrient made of carbon, hydrogen, oxygen, and nitrogen assembled in chains of amino acids. Some of the key functions include building muscle, providing cellular structure for organs and tissues, transporting molecules, and supplying energy. Proteins are constantly broken down and rebuilt by the body, making it essential to consume protein foods daily. Protein recommendations vary from age, activity level, body size, and overall health but ranges from 46 grams to 56 grams per day.
Sources of protein include: lentils, edamame, nuts, tofu, tempeh, seeds, beans, seitan, and oats
Carbohydrates are an energy-providing macronutrient in the form of sugar, starch, or dietary fiber and is the main source of energy for the body. Carbohydrates often receive a bad reputation but complex carbs are great for keeping people full for longer periods of time and releasing energy throughout the day. Simple carbohydrates such as sugar are the carbs that should raise more concern.
