Polysaccharide Functions The three main functions of polysaccharides are providing structural support, storing energy, and sending cellular communication signals. The carbohydrate structure largely determines its function.

Whenever glucose levels decrease, glycogen is broken down to release glucose. Cellulose is one of the most abundant natural biopolymers. The cell walls of plants are mostly made of cellulose, which provides structural support to the cell. Wood and paper are mostly cellulosic in nature.

Starchy foods are an important source of energy. After they are eaten, they are broken down into glucose, which is the body’s main fuel, especially for our brain and muscles. Starchy foods provide important nutrients to the diet including B vitamins, iron, calcium and folate.

Carbohydrates are classified as monosaccharides, disaccharides, and polysaccharides depending on the number of monomers in the molecule. Starch and glycogen, examples of polysaccharides, are the storage forms of glucose in plants and animals, respectively. The long polysaccharide chains may be branched or unbranched.

The combination of two monosaccharides produces disaccharides. Polysaccharides are formed by combining a large number of glucose monomers together. The main difference between sugar and starch is that sugars are disaccharides or monosaccharides whereas starch is a polysaccharide.

Carbohydrates are the body’s main source of energy. In their absence, your body will use protein and fat for energy. It may also be hard to get enough fibre, which is important for long-term health.

Why do you need carbohydrates? Carbohydrates are your body’s main source of energy: They help fuel your brain, kidneys, heart muscles, and central nervous system. For instance, fiber is a carbohydrate that aids in digestion, helps you feel full, and keeps blood cholesterol levels in check.

But the following foods are a better source of carbs.

• Vegetables. All of them.
• Whole fruits. Apples, bananas, strawberries, etc.
• Legumes. Lentils, kidney beans, peas, etc.
• Nuts. Almonds, walnuts, hazelnuts, macadamia nuts, peanuts, etc.
• Seeds. Chia seeds and pumpkin seeds.
• Whole grains.
• Tubers.

Immediately. Reducing your intake of calorie-dense carbs automatically reduces the amount of calories you’re consuming on a daily basis, which forces your body to burn fat stored around your midsection for energy, rather than the sugars it takes from carbohydrates.

When you completely cut carbohydrates out of your diet, you could put yourself at risk for nutrient deficiencies if you don’t replace those nutrients with other food sources. For example, Koff points out that about 70% of Americans don’t get enough magnesium, an important mineral that cells need to “turn off” stress.

It typically takes 2–4 days to enter ketosis if you eat fewer than 50 grams of carbs per day. However, some people may take longer depending on factors like physical activity level, age, metabolism, and carb, fat, and protein intake.

Contrary to popular belief, the burn that we feel in our muscles during exercise is not directly related to caloric burn or the amount of fat that is being burned. Just because you feel a burn in your abdominal muscles during a crunch, it does not mean that your body is burning fat in that area.

Severe carb restriction can cause your body to break fat down into ketones for energy. This is called ketosis. Ketosis can cause side effects such as bad breath, headache, fatigue and weakness. It’s not clear what kind of possible long-term health risks a low-carb diet may pose.

A no-carb diet eliminates almost all carbs and encourages high intakes of fat and protein. It may boost weight loss, heart health, and blood sugar control. Yet, it’s unnecessary to cut all carbs to experience these benefits. Plus, this diet may reduce energy levels and increase your risk of nutrient deficiencies.

High-carb foods that people should try to avoid include:

• candy.
• sugary breakfast cereals.
• white pasta.
• white bread.
• white rice.
• cookies, muffins, and other baked products.
• flavored and sweetened yogurt.
• potato chips.

As one of the most nutritious foods you can find, eggs make an essential component of any low-carb diet. They’re packed with nutrients that boost brain and eye health and contain almost zero carbs.
