Sugar and protein are both essential parts of a healthy diet. However, the body needs protein more than sugar. Protein is a building block of every human cell and is involved in vital biochemical functions of the human body. On the other hand, while sugar is also essential, too much of it can lead to cravings, binge eating, unintentional weight gain, and disease. This article will discuss how much sugar and protein are recommended per day and the best sources for each.

The recommended daily sugar intake
The Dietary Guidelines for Americans recommend limiting added sugars to less than 10% of total calories for individuals aged two years and older. For a 2,000-calorie diet, this translates to 200 calories or 50 grams of sugar daily, which is about 12 teaspoons. However, other healthcare organizations and researchers suggest a more conservative limit of 25 grams of added sugars per day.
The American Heart Association (AHA) recommends stricter limits to combat the obesity and heart disease epidemics. They suggest no more than 100 calories per day (about 6 teaspoons or 24 grams) for adult women and not more than 150 calories per day (about 9 teaspoons or 36 grams) for adult men. The AHA also recommends that children aged 2-18 limit their added sugar intake to less than 6 teaspoons or 24 grams per day, with sugary beverages restricted to no more than 8 ounces per week.
In the United Kingdom, the National Health Service (NHS) recommends keeping total sugar intake below 90 grams daily. This recommendation includes both natural and added sugars. The NHS emphasizes the importance of reducing the consumption of sugary foods and drinks, such as sweets, cakes, biscuits, and fizzy drinks, to maintain a healthy, balanced diet.
It is worth noting that these recommendations are for the general population. Individuals with specific health goals, medical conditions, or dietary preferences may require personalized advice from healthcare professionals or nutrition specialists to determine their recommended daily sugar intake.

Sugar in protein-rich foods
The amount of sugar one should eat per day depends on several factors, and there is no definitive answer. The Dietary Guidelines for Americans recommend a maximum of 50 grams of added sugar per day for a 2,000-calorie diet. However, other healthcare organisations and researchers recommend keeping added sugar intake to under 25 grams daily. In the UK, the NHS recommends a maximum of 90 grams of total sugar per day.
Protein should account for 10% to 35% of your calories. For a 2,000-calorie diet, this equates to 50-175 grams of protein per day. However, it is important to note that excessive protein intake can be detrimental.
When it comes to sugar in protein-rich foods, it is important to distinguish between natural sugars and added sugars. Natural sugars, such as fructose in fruits and lactose in milk, are generally considered part of a balanced diet and offer various health benefits. On the other hand, added sugars like sucrose and high-fructose corn syrup, commonly found in processed foods and baked goods, have been linked to health issues such as diabetes, obesity, and tooth decay.
Some protein-rich foods that are also good sources of natural sugars include dairy products like milk and Greek yoghurt, and fruits like berries. However, certain protein-rich foods can also contain high amounts of added sugars. For example, flavoured Greek yoghurt often contains added sugars, as do some nut butters and protein bars. When incorporating these foods into a high-protein diet, it is important to read nutrition labels and choose options with minimal added sugars.
It is worth noting that the evidence suggests that consuming sugar with a protein-rich meal does not negatively or positively affect protein absorption. However, one study found that consuming a sugar-sweetened drink with a high-protein meal reduced fat breakdown compared to a drink sweetened with a non-nutritive sweetener.

Natural vs added sugars
The amount of sugar that is allowed on a protein diet depends on several factors, such as age, gender, weight, and physical activity level. For example, the recommended dietary allowance to prevent deficiency for an average sedentary adult is 0.8 grams of protein per kilogram of body weight. On the other hand, people who exercise regularly have higher protein needs, ranging from 1.1 to 1.7 grams per kilogram.
When it comes to sugar, it's important to distinguish between natural sugars and added sugars. Natural sugars, such as fructose in fruits and lactose in milk, are generally considered part of a balanced diet. These foods provide essential nutrients like potassium, vitamin C, and folate, and their natural sugars are processed more slowly by the body, resulting in stable metabolism and energy levels.
Added sugars, on the other hand, are those that are added to processed foods during manufacturing or preparation. Examples include sucrose, high-fructose corn syrup, honey, and other chemically manufactured sweeteners. While small amounts of added sugars are fine occasionally, regularly consuming excessive added sugars can lead to health issues. The rapid digestion of added sugars causes a quick spike in blood glucose levels, followed by a sudden drop or "sugar crash," which can leave you feeling hungry, irritable, and craving more sugar.
Consuming large amounts of added sugars over time can contribute to weight gain, obesity, diabetes, heart disease, and other chronic conditions. Additionally, added sugars provide extra calories without any nutritional benefits. Therefore, it is generally recommended to limit the intake of added sugars and opt for naturally sweet whole foods instead. Drinking water instead of sugary drinks, using sugar alternatives like stevia or monk fruit, and incorporating spices like cinnamon and nutmeg in recipes can help reduce added sugar intake.
It's worth noting that individual needs may vary, and it's always a good idea to consult with a healthcare professional or nutrition specialist to determine the appropriate sugar and protein intake for your specific circumstances.

Health risks of excess sugar
There is no simple answer to how much sugar one should eat per day, as it depends on several factors. The Dietary Guidelines for Americans recommend a maximum of 50 grams of added sugar per day for a 2,000-calorie diet. However, other healthcare organisations and researchers recommend keeping added sugar intake to no more than 25 grams daily. In the UK, the NHS recommends a total sugar intake of less than 90 grams per day.
Excess sugar consumption has been linked to various health risks and negative effects on the body. Here are some of the health risks associated with consuming too much sugar:
Weight Gain and Obesity
Excess sugar consumption, especially from sugar-sweetened beverages, has been identified as a major contributor to weight gain and obesity. Liquid calories from sugary drinks do not curb hunger and can easily add extra calories to one's diet, leading to increased weight. Fructose, a common sugar in sweetened beverages, increases hunger and desire for food more than glucose, which can result in excessive calorie intake and weight gain.
Dental Issues
Consuming sugary foods and drinks can lead to dental problems, such as tooth cavities. Bacteria that cause cavities thrive on the sugar that lingers in the mouth after consuming sweet foods or drinks.
Heart Disease
High sugar intake has been linked to an increased risk of heart disease. The excess insulin in the bloodstream from consuming too much sugar can cause inflammation and thickening of the arterial walls, stressing and damaging the heart over time. Additionally, consuming too much sugar can raise blood pressure, another risk factor for heart disease.
Diabetes
Excess sugar consumption is linked to an increased risk of type 2 diabetes. Sugar-sweetened drinks contribute to this risk by elevating blood sugar levels and interfering with the body's ability to regulate hunger and satiety signals.
Cognitive Decline
High-sugar diets have been associated with impaired memory and an increased risk of dementia, Alzheimer's disease, and stroke.
Liver Disease
Consuming too much sugar can overload the liver, leading to a build-up of fat and an increased risk of non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH). These conditions can progress to cirrhosis and may require a liver transplant.
Joint Pain and Arthritis
Excessive sugar intake can worsen joint pain due to the inflammation it causes in the body. Additionally, studies suggest that high sugar consumption may increase the likelihood of developing rheumatoid arthritis.
Skin Aging
The inflammation caused by excess sugar can lead to premature skin aging. Additionally, advanced glycation end products (AGEs) formed when sugar attaches to proteins in the bloodstream can contribute to skin aging.
Mental Health
Studies have linked high sugar intake to an increased risk of depression in adults.
To mitigate the health risks associated with excess sugar consumption, it is recommended to limit added sugars and prioritise a nutrient-dense diet based on whole foods. Natural, zero-calorie sweeteners like stevia and monk fruit can be used as substitutes for sugar.

Calculating your protein needs
There is no simple answer to how much sugar one should eat per day. The maximum amount of added sugars recommended by the Dietary Guidelines for Americans is 50 grams per day for a 2,000-calorie diet. However, other healthcare organisations and researchers recommend not consuming more than 25 grams of added sugars daily. The NHS in the United Kingdom recommends keeping total sugar intake below 90 grams daily.
Protein should account for 10% to 35% of your calories. For a 2,000-calorie diet, this equates to 50-175 grams of protein per day. The recommended dietary allowance to prevent deficiency for an average sedentary adult is 0.8 grams of protein per kilogram of body weight. For example, a person who weighs 165 pounds, or 75 kilograms, should consume 60 grams of protein per day.
If you are over the age of 40 or 50, your protein needs increase to about 1-1.2 grams per kilogram, or 75-90 grams per day for a 165-pound person. People who exercise regularly have higher protein needs, ranging from 1.1-1.5 grams per kilogram. Individuals who engage in intense physical activities, such as weight lifting or endurance training, may require up to 1.2-1.7 grams of protein per kilogram.
Highly active individuals or those aiming to build muscle should generally consume more protein. Some sources suggest an intake of 1.8 to 2 grams of protein per kilogram for highly active people. However, it is important to note that the optimal amount of protein can vary depending on individual factors such as weight, physical activity level, and medical history.
While there is ongoing research on the optimal amount of protein for good health, it is generally recommended to aim for a balanced diet that includes a variety of protein sources. This can include both animal-based and plant-based sources to ensure adequate protein intake while maintaining a healthy nutritional profile.
It is worth noting that excessive protein intake can be considered as consuming more than 2 grams of protein per kilogram of body weight per day. Consulting with a dietitian or a specialist can help determine your individual protein needs based on your specific circumstances and health goals.
