Carbohydrate-based energy sources -
The microbiome is an enormous collection of microbial organisms that live on and in your body, most of them within the gastrointestinal tract or the gut. Many of the microbes within the gut are healthy bacteria that help support immune and digestive health.
Certain carbohydrates — like fiber — act as food for the good bacteria in the gut and promote their growth. Eating foods high in fiber, like fruits, vegetables and whole grains, can also help with regular bowel movements, minimize constipation-related issues and may help lower cholesterol and blood sugar.
Hakim Bouzamondo, MD, MSC, MBA, division vice president of Global Research and Development, Abbott. And they play an essential role. Take nutrition supplements, for example. Some nutrition supplements, like nutrition drinks, are nutrient-dense and designed to provide important macro-nutrients, vitamins, and minerals.
Carbs are one of the main energy sources and play an important role in the taste and consistency, too. Sugar can add thickness and also help prevent clumping of protein in powder mixes, which can impact texture and consistency.
Sugar also provides sweetness to nutrient-dense foods and helps enhance positive flavors or mask negative ones, so the products are easy to drink. For some people our nutrition products provide their total nutrition, so the products must be balanced with important nutrients — including carbohydrates — so people can get the nutrition they need to grow, heal or thrive.
And understanding the different kinds of carbohydrates, where to find them in foods and how to prioritize them in your diet, will help you enjoy a variety of foods while providing your body with essential nutrients. A Look at Nutrition Trends. Key Takeaways.

Most people in the United States exceed the recommended daily limits for added sugar. However, limiting added sugar as much as possible is best for overall health. The American Heart Association recommend that women limit added sugar to less than 6 teaspoons 25 g per day and men limit their intake to less than 9 teaspoons 36 g per day.
The chemical structures of carbohydrates contain carbon, hydrogen, and oxygen atoms. Two basic compounds make up carbohydrates: Aldehydes, which are double-bonded carbon and oxygen atoms, plus a hydrogen atom, and ketones, which are double-bonded carbon and oxygen atoms, plus two additional carbon atoms.
Carbohydrates can combine to form polymers, or chains, to create different types of carbohydrates. Carbohydrate can be monosaccharides, disaccharides, or polysaccharides.
Polysaccharides are chains of many sugars. They can consist of hundreds or thousands of monosaccharides. Polysaccharides act as food stores for plants and animals. Examples include:. Monosaccharides and disaccharides are simple carbohydrates , and polysaccharides are complex carbohydrates.
Simple carbohydrates are sugars. They consist of just one or two molecules. They provide a rapid source of energy, but the person soon feels hungry again. Examples include white bread, sugars, and candies. Complex carbohydrates consist of long chains of sugar molecules.
This includes whole grains and foods that contain fiber. Examples include fruits, vegetables, beans, and whole grain pasta.
Complex carbohydrates make a person feel full for longer and have more health benefits than simple carbohydrates, as they contain more vitamins , minerals, and fiber.
In a typical diet, carbohydrates are the main energy source for the body. The body uses them as fuel for the cells. Many people have turned to low carb diets, such as the keto diet , for their potential health benefits and weight loss.
However, some types of carbohydrates — including whole grains and dietary fiber — have substantial health benefits. In fact, according to the Physicians Committee for Responsible Medicine , those who eat the most carbohydrates — especially from natural sources such as beans, whole grains, and vegetables — have a lower risk for obesity , type 2 diabetes , and heart disease.
Other types of carbohydrates, including simple carbohydrates such as white bread, have much lower nutritional value. Added sugars are a type of carbohydrate that can have adverse health effects. Eating large amounts of foods that contain added sugars can contribute to obesity, type 2 diabetes, and cardiovascular disease.
When making dietary changes, it is important to aim for a healthful diet that contains the range of nutrients that the body needs. Some argue that the global rise in obesity is linked to a high intake of carbs.
However, a number of factors contribute to rising obesity rates, including :. Many manufacturers promote low carb diets to sell weight loss products, including nutritional bars and powders. These products are not often healthful as many contain colorings, artificial sweeteners, emulsifiers, and other additives and are typically low in vitamins, minerals, and antioxidants, making them similar to junk food.
After a meal, the body breaks carbohydrates down into glucose, causing blood sugar levels to increase. Over time, repeated spikes in blood sugar levels can damage the cells that make insulin, wearing them out. Eventually, the body may stop producing insulin, or may not be able to use it properly.
This is known as insulin resistance. Eating carbohydrates or sugars alone does not cause diabetes. Carbohydrates are an important source of nutrients in most diets. However, people are more likely to have insulin resistance and develop type 2 diabetes if they have overweight or obesity, which can be linked with a diet high in sugar.
Dates offer important micronutrients like calcium, B vitamins, non-heme iron, potassium, copper and magnesium. Enjoy them chopped up in salads or rice dishes, or as a satisfying snack filled with nut butter.
Along with other sources of dairy, yogurt is a carb choice that provides lactose, a naturally occurring sugar.
While there are yogurts higher in protein than others like Greek yogurt , all yogurts offer important nutrients aside from carbs. Yogurt is a good source of bone-protecting calcium and vitamin D, and gut-balancing probiotics. One thing you'll want to be mindful of is sugar in yogurt.
You should try to opt for Greek yogurts, which are naturally lower in sugar and higher in protein than regular yogurt. Similar to our other carb picks, the best rule of thumb to follow when choosing yogurt is to go with what you like most. Have it as a little snack alone, or try yogurt in sweet-but-tart breakfasts like smoothies and parfaits, or in savory fare like dips and condiments.
While some carbs may be more nutritious than others, Hartley says her key carb-related recommendation is to eat enough of them and include them regularly at meals and snacks. Otherwise, going a long period of time without carbs can lead to blood sugar instability.
Food is fuel and nourishment, but it is also so much more — food, and food traditions and experiences, can be one way to nourish ourselves emotionally.
Oftentimes, carb-rich "fun" foods are significant parts of emotional eating experiences. Having a healthy relationship to food includes giving yourself permission to include all types of carbs, and enjoy joyful, adventurous and sentimental eating experiences. Caroline L.

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.

Not getting enough carbohydrates can have consequences such as weakness, fatigue, constipation, vitamin deficiencies, and difficulty concentrating.
Complex carbohydrates are an efficient source of energy that fuels muscle contractions. Once eaten, carbs are broken down into smaller sugars glucose, fructose, and galactose to be used as energy for immediate tasks.
Any unused glucose is converted into glycogen and stored in the muscles and liver for future use. Glycogen is the energy source most often used for short, intense bouts of exercise such as sprinting or weightlifting.
Because glycogen is stored in muscles, it is immediately accessible. During bursts of activity, the stored glycogen is converted back to glucose and burned for fuel. This is the typical energy source for the first few minutes of any sport.
During endurance exercise , glycogen can also break down fat into something the muscles can use for fuel. Protein for example, from a source such as whey protein powder can also be broken down and used as a last resort, but this stresses the kidneys and limits the body's ability to build and maintain muscle tissue.
Beyond muscle contraction, carbs supply energy to the brain. If you have ever felt low energy or experienced a brain fog during exercise, it is likely because you are not getting enough carbs. Consuming enough carbohydrates ensures you have access to the energy you need for exercise.
It also helps maintain mental sharpness for endurance sports. One gram of carbohydrates provides four calories of energy. The body can store a maximum of 15 grams of glycogen per kilogram of body weight 15 grams per 2. This would mean that a pound athlete could store up to 1, grams of glycogen 4, calories , fueling high-intensity exercise for quite some time.
Larger muscle mass provides greater glycogen storage, but also increases the demands for energy. While every person is unique, the average carbohydrate storage capacity in the body roughly breaks down as follows:.
Exercise and diet changes can deplete these energy stores. Athletes often refer to this as " hitting the wall. This is typically referred to as "carb-loading.
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. Learn More.

The energy content of food is expressed as "calories" "calories" are in reality kcal or kilocalories as defined in chemistry; 1 kcal will heat one liter of water one degree C. Energy-dense foods with high caloric content are generally those with high carbohydrate, protein, or fat content - for example, pasta, bread, oatmeal, grits, and other cooked whole grains and porridges consumed around the world as staples; plant oils or animal lard present in cooked foods, or meat and cheese. It is interesting to note that gram for gram, fats contain over twice the energy density of carbohydrates or protein: about 9 kcal per gram for fats versus only about 4 kcal per gram for carbohydrates and protein.
