What is the nutritional value of 1 cup of sugar?

3 min read

According to USDA data, one standard cup (200g) of white, granulated sugar contains approximately 774 calories. These calories are derived almost exclusively from its sugar content, offering no significant vitamins, minerals, fiber, or other beneficial nutrients. This absence of nutritional benefits is why sugar is famously known as a source of "empty calories".

Quick Summary

One cup of granulated sugar delivers over 770 empty calories with no vitamins, minerals, or fiber. It provides quick energy without nutritional benefits and can lead to serious health issues like weight gain, insulin resistance, and cardiovascular disease when consumed excessively.

Key Points

  • 774 Calories: One standard cup (200g) of granulated white sugar contains approximately 774 calories.

  • Empty Calories: These calories are considered "empty" because sugar provides energy without any significant vitamins, minerals, or fiber.

  • High Carbohydrate Content: Nearly all of the 200g weight of a cup of granulated sugar consists of carbohydrates, primarily sucrose.

  • Zero Protein or Fat: Granulated sugar contains 0g of both protein and fat, offering no support for muscle repair or other metabolic functions.

  • Negligible Nutrients: While trace minerals exist in some minimally refined sugars like brown sugar, the amount is nutritionally insignificant when considering the high caloric load.

  • Excessive Intake Risk: A single cup of sugar contains far more than the recommended daily added sugar intake, increasing the risk of weight gain, insulin resistance, and other chronic health issues.

The Empty Calories of Granulated Sugar

Granulated sugar, whether white or brown, is a highly refined carbohydrate. The refining process strips the sugar cane or sugar beet of all its natural minerals, vitamins, and fiber, leaving behind concentrated sucrose. The result is a substance that offers energy in the form of calories but nothing else of nutritional value. A single cup of granulated sugar, which weighs about 200 grams, provides a significant caloric load without any offsetting nutritional benefit.

Nutritional Breakdown of 1 Cup of Granulated Sugar

For context, a single cup of granulated sugar (approximately 200g) offers the following nutritional profile based on USDA data:

  • Calories: 774 kcal
  • Carbohydrates: 200g, consisting almost entirely of sugar
  • Protein: 0g
  • Total Fat: 0g
  • Dietary Fiber: 0g
  • Vitamins: 0mg (except for trace amounts of some B vitamins like Riboflavin in some datasets)
  • Minerals: 0mg (with negligible trace amounts of minerals like calcium, iron, and potassium reported in some analyses)

Comparing Different Types of Sugar

While granulated sugar is a common benchmark, it is helpful to compare its nutritional content with other types of sugar to see if there are any meaningful differences. As shown in the table below, while some minimally refined sugars retain slightly more minerals, the difference is not significant enough to change their "empty calorie" status.

Nutrient (per 1 cup) White Granulated Sugar Packed Brown Sugar Powdered Sugar (sifted)
Calories ~774 kcal ~829 kcal ~400 kcal
Carbohydrates ~200g ~214g ~100g
Total Sugars ~200g ~212g ~98g
Calcium ~2mg ~187mg negligible
Iron ~0.1mg ~4.2mg negligible
Potassium ~4mg ~761mg negligible

It is important to note that powdered sugar weighs less per cup due to its sifted, less dense nature, which is why its caloric and sugar values appear lower. Brown sugar contains more trace minerals because it includes molasses, but the amount is still too small to offer substantial nutritional benefit relative to its high calorie content.

Health Implications of Excessive Sugar Intake

Consuming a single cup of sugar, which far exceeds the recommended daily intake for added sugars, can have immediate and long-term health consequences. The American Heart Association recommends no more than 6 teaspoons (25 grams) of added sugar per day for women and 9 teaspoons (38 grams) for men. A single cup of sugar contains roughly 48 teaspoons, representing an extreme amount of simple carbohydrates.

Key health risks include:

  • Weight gain and obesity: Excess calories from sugar are easily converted to and stored as fat, contributing to weight gain.
  • Insulin resistance and Type 2 diabetes: Constant high consumption of sugar leads to high insulin levels, which can cause the body's cells to become resistant to insulin over time.
  • Cardiovascular disease: High sugar intake has been linked to increased risk factors for heart disease, such as inflammation, high blood pressure, and high cholesterol.
  • Non-alcoholic fatty liver disease (NAFLD): The liver processes fructose, and excessive intake can cause it to be overworked, leading to fat accumulation and damage.
  • Dental problems: The bacteria in the mouth feed on sugar, producing acid that can erode tooth enamel and cause cavities.
  • Cognitive decline: Some studies suggest that excessive sugar consumption can negatively impact brain function and memory.

Reading Nutrition Labels

Understanding the nutritional value of sugar means learning to spot it on food labels, where it may be listed under many different names. This is especially crucial for highly processed foods that contain significant amounts of hidden sugar. Some common aliases for added sugar include corn syrup, dextrose, fructose, sucrose, and molasses.

Conclusion

In conclusion, 1 cup of sugar provides a large number of calories (approx. 774 kcal) and virtually no essential nutrients like vitamins, minerals, or fiber. It is a textbook example of "empty calories," offering a quick burst of energy without supporting overall bodily health. Consuming sugar in this quantity far surpasses recommended daily limits and is associated with multiple health risks, including weight gain, insulin resistance, and increased risk of cardiovascular disease. Health-conscious individuals should prioritize whole food sources of carbohydrates, which provide fiber and other nutrients, and practice moderation with added sugars. For more detailed information on limiting your sugar intake, consult the guidelines provided by health organizations like the American Heart Association.

Frequently Asked Questions

One standard cup (200 grams) of white, granulated sugar contains approximately 774 calories.

Sugar is considered an empty calorie source because it provides a high amount of calories but delivers no essential nutrients like vitamins, minerals, or dietary fiber.

A single cup of granulated sugar contains about 200 grams of carbohydrates, which are nearly all simple sugars (sucrose).

While brown sugar contains trace amounts of minerals like calcium, iron, and potassium due to its molasses content, the quantity is too small to provide any significant nutritional benefit compared to its high sugar and calorie content.

Excessive sugar consumption can lead to health risks such as weight gain, obesity, insulin resistance, type 2 diabetes, heart disease, and dental problems.

The American Heart Association recommends that women consume no more than 6 teaspoons (25 grams) of added sugar per day, and men no more than 9 teaspoons (38 grams) per day.

To identify hidden sugar, look for aliases on food labels such as corn syrup, dextrose, fructose, molasses, malt syrup, cane juice, and high fructose corn syrup.
