Sugar is a type of carbohydrate that is naturally found in some foods, such as milk, fruit, and vegetables, and is also added to a wide variety of foods. While sugar is a source of energy in our diet, consuming too much sugar can lead to weight gain and serious health problems, including diabetes, dementia, and obesity. However, sugar is not harmful in small amounts, and a moderate intake of sugar can be part of a healthy diet. This is because the body breaks down all carbohydrates into sugar, which is necessary for energy and healthy functioning.

What You'll Learn
Glucose is essential for energy and healthy functioning
Sugar is a type of carbohydrate that occurs naturally in many foods, such as fruits, vegetables, and milk. The body breaks down all carbohydrates into sugar, specifically glucose, which is the simplest type of sugar.
Maintaining healthy blood glucose levels is vital for the body's everyday functioning. If blood sugar levels dip too low (hypoglycemia) or grow too high (hyperglycemia), it can affect the body's functioning. The liver plays a crucial role in regulating blood glucose levels. Glycogen, a multibranched polysaccharide of glucose, is the storage form of glucose in the human body and is primarily found in the liver and skeletal muscle.
The body requires no added sugars to function properly. Excess sugar consumption can lead to serious health problems, including diabetes, heart disease, and obesity.

Natural sugars in fruits and vegetables are beneficial
Sugar is a type of carbohydrate that is found naturally in some foods or added to others. While excessive sugar consumption can lead to various health issues, natural sugars in fruits and vegetables are beneficial when consumed in moderation as part of a balanced diet.
Firstly, natural sugars in fruits and vegetables are accompanied by fiber, which slows down the absorption of sugar, reducing spikes in blood sugar levels. Whole fruits, in particular, take time to chew and digest, allowing the body to easily tolerate the small amounts of fructose. This is in contrast to added sugars, which can cause rapid spikes in blood glucose levels, potentially increasing the risk of health issues such as diabetes, heart disease, and obesity.
Secondly, fruits and vegetables provide essential vitamins, minerals, and antioxidants. For example, fruits are an excellent source of vitamin C, and some also contain vitamin A, folate, and potassium. Antioxidants in fruits help protect cells from damage caused by free radicals. A 2021 review found that increasing fruit intake by just one serving per day could reduce the risk of cardiovascular disease, coronary heart disease, stroke, and oral cancer. Additionally, a study of 9,665 U.S. adults found that a high intake of fruits and vegetables was associated with a 46% lower risk of diabetes in females.
Furthermore, the natural sugars in fruits and vegetables can provide a rapid energy boost without the negative consequences of added sugars. This can be especially beneficial for athletes and individuals with low blood sugar. While sugar-free alternatives are available, research suggests that consuming artificial sweeteners may be linked to adverse effects, including weight gain and an increased risk of developing certain health conditions.
In conclusion, natural sugars in fruits and vegetables are beneficial when consumed as part of a balanced diet. These foods provide essential nutrients and energy while helping to regulate blood sugar levels. However, it is important to note that excessive consumption of any type of sugar can contribute to health issues, and individuals with certain conditions may need to monitor their fruit intake due to its fructose content.

Added sugars are unnecessary and harmful in excess
Sugar is a type of carbohydrate that occurs both naturally and artificially in many foods and drinks. While the body breaks down all carbohydrates into sugar to use as energy, added sugars are unnecessary for the body to function properly.
Added sugars are any sugars in foods that are not naturally occurring, such as sugar in baked goods, sweetened beverages, and processed foods. They are often added by food manufacturers to increase flavour and extend shelf life. The body does not require added sugars to function properly, and consuming too much can lead to serious health problems.
Excess sugar consumption can cause weight gain and obesity, as the calories from free sugars can quickly add up, increasing the total number of calories consumed. This can also lead to an increased risk of developing type 2 diabetes, heart disease, and even some cancers. Additionally, added sugars have been linked to raised blood pressure, inflammation, and an increased risk of dementia.
The World Health Organization (WHO) and the United Kingdom's National Health Service (NHS) recommend that less than 5% of your daily calories come from added sugars. For an adult, this equates to roughly 30 grams or 7 sugar cubes of free sugars per day. To reduce added sugar intake, it is recommended to cut down on sugary drinks and foods such as sweets, cakes, and biscuits, and to choose unsweetened or naturally sweet foods like fruit.
While some people advocate for cutting out all added sugars, others suggest that consuming natural sugars in moderation is acceptable. It is important to note that sugar is not a required nutrient, and limiting added sugars can be beneficial for overall health and weight management.

Sugar's impact on health is debated, but moderation is key
Sugar is a type of carbohydrate that is found naturally in some foods, such as fruit (fructose and glucose) and milk (lactose), or added to others during preparation or processing. It provides a source of energy in our diet, as the body breaks down carbohydrates into simple sugars, such as glucose, that can be readily used.
However, consuming too much sugar can lead to serious health problems. Excess sugar consumption can cause weight gain, as the calories from free sugars can quickly add up. Being overweight increases the risk of health problems such as heart disease, certain cancers, and type 2 diabetes. Sugar is also one of the main causes of tooth decay.
Furthermore, high blood glucose levels can cause brain problems and increase the risk of dementia, even in people without diabetes. Sugar-sweetened beverages are the main source of added sugar in the US, with these drinks accounting for 47% of added sugars in a typical diet. Snacks and candies also contribute significantly, making up about 31% of added sugars.
While some people suggest cutting out added sugars but consuming natural sugars, others believe it is best to eliminate all sugars. Despite these differing opinions, many researchers and healthcare organizations agree that consuming too much sugar is linked to an increased risk of developing chronic health conditions.
However, it is important to note that eating sugar in moderation is unlikely to be harmful. Experts define a moderate intake as about 10% of your total energy intake per day. The World Health Organization (WHO) and the United Kingdom's National Health Service (NHS) recommend getting less than 5% of your daily calories from added sugars. The American Heart Association (AHA) suggests that women consume less than 6 teaspoons (25 grams) and men less than 9 teaspoons (36 grams) per day.
Additionally, sugar can make nutritious grain foods, such as wholegrain bread and cereals, more palatable, encouraging people to eat more of these healthy options. Natural sugars found in fruits and vegetables do not need to be cut down, and they can be a good way to add sweetness to your diet. Overall, while the impact of sugar on health is debated, the key is to consume sugar in moderation as part of a balanced diet.

Sugar contributes to weight gain and obesity
Sugar is a type of carbohydrate that is naturally found in some foods or added to others. The body breaks down all carbohydrates into sugar, which is converted into glucose and used as a source of energy. While sugar is essential for the body's energy, excessive sugar consumption can lead to weight gain and obesity.
Sugar-sweetened beverages, such as soft drinks, are a significant contributor to added sugar intake. These drinks can contain high amounts of sugar, often exceeding the recommended daily limit. For example, a can of cola can have as much as nine cubes of sugar. Overconsumption of these sugary drinks can quickly increase the total calories consumed, leading to weight gain over time.
Snacks and candies also play a significant role in added sugar intake, contributing about 31% of the total added sugars in the diet. Consuming excessive amounts of sugary treats can lead to a calorie surplus, which is a key factor in weight gain. This is because consuming more calories than the body can burn results in the excess calories being stored as fat.
Additionally, the body does not require added sugars to function properly. These added sugars, also known as free sugars, are sugars added to food or drinks, and they are distinct from the natural sugars found in fruits, vegetables, and milk. The excessive consumption of free sugars is linked to an increased risk of developing chronic health conditions, including obesity.
The link between sugar consumption and weight gain is supported by various studies, including the CARDIA study. This study found that greater added sugar intake was associated with a 2.3 kg increase in weight and a 2.2 cm increase in waist circumference over 30 years. The findings also indicated an increased risk of developing obesity and abdominal obesity.
In summary, while sugar is a necessary part of our diet, providing energy for our bodies, excessive consumption, especially of added sugars, can lead to weight gain and obesity. It is important to limit the intake of added sugars, found in sugary drinks and treats, and focus on a balanced diet with nutrient-dense whole foods to maintain a healthy weight.
