130 grams.
In order to meet your minimum carbohydrate requirements, you must first know what foods contain carbohydrate. Because carbohydrates are found in most plant-based foods, whole grains, starches, fruits and vegetables are all excellent sources of this essential nutrient. Because carbohydrates' primary function is to fuel the body, athletes needs a high percent of their overall energy intake from carbohydrates. On the other hand, individuals with diabetes may not need as many calories from carbohydrates due to the risk of high blood sugar. For most people, this is still below the recommended percentage of calories from carbohydrates. If you consumed 1,200 calories per day, 130 grams of carbohydrates would make up 43 percent of your calories, but it would only be 26 percent of your daily calories if you consumed 2,000 calories per day. It can also use protein and fat for some of its energy needs, but carbohydrates are the preferred source of energy for your brain. Severely limiting carbohydrates can affect your brain function. Carbohydrates are one of the three essential nutrients that provide energy, or calories, to the human body. Each gram of digestible carbohydrate provides the body with 4 calories. Because carbohydrates' primary function is to fuel the body, athletes needs a high percent of their overall energy intake from carbohydrates. On the other hand, individuals with diabetes may not need as many calories from carbohydrates due to the risk of high blood sugar. So, summing up mid-article, the absolute requirement for carbohydrates is zero grams per day. However, depending on protein intake, a practical minimum for carbs lies between 50 grams/day (if someone functions well in ketosis) to 100-120 grams per day (if they don’t function well in ketosis). Logically, a practical upper limit for carbohydrates intake would be a situation where they made up 100% of someone’s total energy intake. An average individual has a daily caloric intake in the realm of 14-16 cal/lb. The standard recommendation for carbohydrate is 45-65% of total calories. This means if 1800 calories are eaten each day, the recommended amount of carbohydrate is 202-292 grams based on 45-65% calories from carbohydrate. Many organs in the body can use protein or fat for energy if carbohydrate is not available. The brain, however, requires some carbohydrate (glucose) to function. The brain uses an average minimum of 130 grams carbohydrate daily. This minimal amount is where the RDA is derived. The University of Maryland Medical Center website notes a minimum recommended carbohydrate intake of 100 grams to 150 grams per day. The Institute of Medicine, the organization that sets the recommended dietary allowances for nutrients, recommends consuming at least 130 grams of carbohydrates per day. It can also use protein and fat for some of its energy needs, but carbohydrates are the preferred source of energy for your brain. Severely limiting carbohydrates can affect your brain function. Your body needs carbohydrates to supply it with energy. It can also use protein and fat for some of its energy needs, but carbohydrates are the preferred source of energy for your brain. Severely limiting carbohydrates can affect your brain function. Carbohydrate (glucose) is your body's favorite energy source. Many organs in the body can use protein or fat for energy if carbohydrate is not available. The brain, however, requires some carbohydrate (glucose) to function. The brain uses an average minimum of 130 grams carbohydrate daily. This minimal amount is where the RDA is derived. Consider that other parts of the body would like to use carbohydrate for energy as well We need this amount of carbohydrates because they are the body’s main source of fuel. They are easily used for energy. All the tissues of the body can use glucose for energy. They are needed for the central nervous system and also the kidneys, brain and muscles (including the heart) to function properly. Carbohydrates can be stored in the muscles and liver (glycogen) and later used for energy. The recommended intake is a minimum of 130 grams/day, or 45 - 65 percent of daily calories for adults, independent of age or activity level. This is the minimum needed for your brain to function. Athletes are recommended to consume 6 - 10 grams for every kilogram of body weight per day. For example, a typical man weighing 70 kilograms needs 420 grams of carbs per day to fuel his activity. The amount of carbohydrates a person should consume depends on their condition and activity. For example, a diabetic with difficult to control blood sugars, should aim on the lower end: 45% of their calories from carbohydrates.
