There are three main types of sugars: monosaccharides, disaccharides, and polysaccharides. Monosaccharides are single sugar molecules, such as glucose and fructose. Disaccharides are two monosaccharides bonded together, such as sucrose and lactose. Polysaccharides are long chains of monosaccharides, such as starch and cellulose.
No, not all sugars are bad for you. Natural sugars found in fruits, vegetables, and dairy products are important sources of energy and nutrients for the body. However, added sugars found in processed foods and drinks should be consumed in moderation as they can contribute to health issues if consumed in excess.
When we consume sugars, they are broken down into glucose, which is then absorbed into the bloodstream. The hormone insulin helps to regulate the amount of glucose in the blood and facilitates its transport into cells for energy. Excess glucose is stored in the liver and muscles as glycogen for later use.
Consuming too much sugar can lead to weight gain, tooth decay, and an increased risk for chronic diseases such as diabetes and heart disease. It can also cause spikes in blood sugar levels, which can lead to feelings of fatigue and irritability.
The American Heart Association recommends limiting added sugars to no more than 25 grams (6 teaspoons) per day for women and 36 grams (9 teaspoons) per day for men. However, it is important to note that everyone's sugar needs may vary based on age, activity level, and overall health.
