Carbohydrates for energy -
There are two different types of carbohydrates found in food: simple and complex. Of the two, complex carbs pack more nutrients than simple carbs. They are higher in fiber and are more slowly digested, meaning that they are less likely to cause spikes in blood sugar.
Simple carbohydrates are absorbed and converted very quickly, providing a rapid source of energy. Some naturally occur in milk and fruit, but most of the simple carbs in American diets are sweeteners that are added to foods, such as sugar, corn syrup, or fruit juice concentrations.
Sports drinks and sweetened fruit juices are quick sources of simple carbs. While simple carbs can provide you with the fuel you need for explosive bursts of energy, they are quickly spent and may be less appropriate for people with type 2 diabetes.
Complex carbohydrates take longer to be digested, absorbed, and metabolized. Thus, they provide energy at a slower rate and are often stored as glycogen. Ideal sources include foods high in starch, such as whole-grain bread, cereals, pasta, and grains.
To maintain energy, eat carbohydrates before and after intense exercise. It is equally important to eat a balanced diet with the appropriate proportion of carbs, proteins, and healthy fats.
For athletes, the proportion may need to be adjusted to accommodate increased energy needs. Carbohydrates provide energy for your body, brain, heart, and nervous system, as well as assist with digestion and help control blood cholesterol, blood glucose, and insulin metabolism.
Meat, fish, some cheeses, eggs, oils, and plain coffee or tea don't contain carbohydrates. Foods that are low in carbohydrates include non-starchy vegetables , high-fat fruits think avocado and coconut , nuts, and seeds.
Glucose is stored as glycogen, a readily available form of glucose, in the liver and muscles for quick energy when needed. Carbohydrates are converted into blood sugars such as glucose, fructose, and galactose in the body for immediate energy needs.
Glucose is then converted into glycogen and stored for use in the future,. Carbohydrates are an important source of energy. How many carbs the body requires differ from person to person, so talk to your doctor or a registered dietitian to determine what your unique dietary carbohydrate needs are.

The label shows total carbohydrates — which can include fiber, total sugars and added sugars. Carbohydrates are the body's main fuel source.
During digestion, sugars and starches are broken down into simple sugars. They're then absorbed into the bloodstream, where they're known as blood sugar blood glucose.
From there, glucose enters the body's cells with the help of insulin. Glucose is used by the body for energy. Glucose fuels your activities — whether it's going for a jog or simply breathing and thinking.
Extra glucose is stored in the liver, muscles and other cells for later use. Or extra glucose is converted to fat. Some evidence suggests that whole grains and dietary fiber from whole foods help lower your risk of heart disease and stroke.
Fiber may also protect against obesity, colon and rectal cancers, and type 2 diabetes. Fiber is also essential for optimal digestive health. Evidence shows that eating plenty of fruit, vegetables and whole grains can help you control your weight.
Their bulk and fiber content aids weight control by helping you feel full on fewer calories. Despite what proponents of low-carb diets claim, few studies show that a diet rich in healthy carbs leads to weight gain or obesity. Carbohydrates are an essential part of a healthy diet, and they provide many important nutrients.
Still, not all carbs are equally good for you. So choose your carbohydrates wisely. Limit foods with added sugars and refined grains, such as sugary drinks, desserts and candy. These are high in calories but low in nutrition.
Instead, select fruits, vegetables and whole grains. There is a problem with information submitted for this request. Sign up for free and stay up to date on research advancements, health tips, current health topics, and expertise on managing health.

Products and services. Carbohydrates: How carbs fit into a healthy diet Carbohydrates aren't bad, but some may be healthier than others. By Mayo Clinic Staff.
It is vital for use during long periods of high-intensity exercise. In circumstances in which you have all of the glucose your body needs and your glycogen stores are full, your body can convert excess carbohydrates into triglyceride molecules and store them as fat.
Your body can transform extra carbohydrates into stored energy in the form of glycogen. Several hundred grams can be stored in your liver and muscles. Glycogen storage is just one of several ways your body makes sure it has enough glucose for all of its functions.
When glucose from carbohydrates is lacking, muscle can also be broken down into amino acids and converted into glucose or other compounds to generate energy. Severe losses of muscle mass have been associated with poor health and a higher risk of death 3.
However, this is one way the body provides adequate energy for the brain, which requires some glucose for energy even during periods of prolonged starvation. Consuming at least some carbohydrates is one way to prevent this starvation-related loss of muscle mass.
These carbs will reduce muscle breakdown and provide glucose as energy for the brain 4. Other ways the body can preserve muscle mass without carbohydrates will be discussed later in this article. Consuming at least some carbs can prevent muscle breakdown in this scenario.
Unlike sugars and starches, dietary fiber is not broken down into glucose. Instead, this type of carbohydrate passes through the body undigested. It can be categorized into two main types of fiber : soluble and insoluble. Soluble fiber is found in oats, legumes and the inner part of fruits and some vegetables.
While passing through the body, it draws in water and forms a gel-like substance. This increases the bulk of your stool and softens it to help make bowel movements easier. In a review of four controlled studies, soluble fiber was found to improve stool consistency and increase the frequency of bowel movements in those with constipation.
Furthermore, it reduced straining and pain associated with bowel movements 5. On the other hand, insoluble fiber helps alleviate constipation by adding bulk to your stools and making things move a little quicker through the digestive tract. This type of fiber is found in whole grains and the skins and seeds of fruits and vegetables.
Fiber is a type of carbohydrate that promotes good digestive health by reducing constipation and lowering the risk of digestive tract diseases. Certainly, eating excessive amounts of refined carbs is detrimental to your heart and may increase your risk of diabetes.
However, eating plenty of dietary fiber can benefit your heart and blood sugar levels 7 , 8 , 9. As viscous soluble fiber passes through the small intestine, it binds to bile acids and prevents them from being reabsorbed.
To make more bile acids, the liver uses cholesterol that would otherwise be in the blood. Controlled studies show that taking Additionally, fiber does not raise blood sugar like other carbohydrates do. In fact, soluble fiber helps delay the absorption of carbs in your digestive tract.
This can lead to lower blood sugar levels following meals A review of 35 studies showed significant reductions in fasting blood sugar when participants took soluble fiber supplements daily. It also lowered their levels of A1c, a molecule that indicates average blood sugar levels over the past three months Although fiber reduced blood sugar levels in people with prediabetes, it was most powerful in people with type 2 diabetes Excess refined carbohydrates can increase the risk of heart disease and diabetes.
As you can see, carbohydrates play a role in several important processes. However, your body has alternative ways to carry out many of these tasks without carbs.

Thus, dietary carbohydrates do not appear to increase an individual's fat content by de novo lipogenesis. The intake of dietary carbohydrates mainly has the effect of inhibiting fat oxidation while glucose oxidation is increased. Dietary carbohydrates are involved in the control of energy balance because the regulation of food intake depends, in part, on the carbohydrate need of the individual. Because there is an obligatory requirement for glucose in several organs such as the brain, a spontaneous increase in food intake is seen when the diet has a low-carbohydrate, high-fat content.

Carbohydrates are found in a wide array of both healthy and unhealthy foods—bread, beans, milk, popcorn, potatoes, cookies, spaghetti, soft drinks, corn, and cherry pie. They also come in a variety of forms. The most common and abundant forms are sugars, fibers, and starches.
