Sugarcane Juice: Benefits, Nutrition & Side Effects

Sugarcane juice is pressed from the stems of Saccharum officinarum and sold fresh across India, usually from a roadside crusher. It is a carbohydrate drink carrying a small amount of minerals, and it is drunk mainly for refreshment in heat.

Two things shape everything below. The sugar in it is free sugar rather than the kind locked inside a whole fruit, and the juice is often prepared in conditions that studies have examined directly. Both are covered here, alongside the nutrition figures and what the research supports.

What Are the Benefits of Sugarcane Juice?

The clearest evidence concerns rehydration after exercise. A 2013 trial in the Asian Journal of Sports Medicine[1] tested 15 male athletes who cycled to exhaustion on three occasions. They drank sugarcane juice, a commercial sports drink or plain water.

Its authors concluded that sugarcane juice may be as effective as a sports drink and as plain water during exercise, and as effective a rehydration drink as either. They also describe it as supporting muscle glycogen resynthesis after exercise.

That is a narrow finding from a small trial, and it is the strongest human evidence retrieved for this article. Claims made for sugarcane juice beyond rehydration were not supported by any source that could be opened.

What Is the Nutritional Value of Sugarcane Juice?

The composition used in that trial is the clearest figure set retrieved. It describes fresh juice rather than a packaged drink.

Nutrient	What 100 g of sugarcane juice provides
Energy	Sugarcane juice provides 39 kcal per 100 g on the trial’s stated composition.
Carbohydrate	Carbohydrate is 9.1 g per 100 g.
Potassium	Potassium is 360 mg per 100 g.
Calcium	Calcium is 74 mg per 100 g.
Phosphorus	Phosphorus is 22 mg per 100 g.
Sodium	Sodium is 20 mg per 100 g.
Iron	Iron is 0.1 mg per 100 g.

Those figures come from a single trial rather than a national food table. Two Indian sources were sought for this article and neither could be read. The ICMR-NIN Indian Food Composition Tables and a government document on sugarcane products are both published as image files with no extractable text.

Does Sugarcane Juice Contain Protein?

Barely any. The composition reported in the cycling trial lists carbohydrate, minerals and energy, and gives no protein value at all.

A packaged sugarcane juice drink listed in the United States Department of Agriculture database[2] declares 0.29 g of protein in a 350 ml can. That is a label figure for one branded product, not a measurement of fresh juice.

Sugarcane juice is best understood as sugar and water carrying some minerals. Anyone drinking it for protein has chosen the wrong drink.

Is Sugarcane Juice Good for Diabetes?

The sugar in it behaves as free sugar, which is the category that guidance restricts. The NHS[3] defines free sugars to include the sugars in honey, syrups, nectars and unsweetened juices. Sugars naturally present in whole fruit, vegetables and milk do not count.

The NHS advises adults to have no more than 30 g of free sugars a day. It states that too much sugar contributes to excess calories and weight gain, which raises the risk of type 2 diabetes among other conditions.

The cycling trial supports the same picture from the other direction. Post-exercise blood glucose was significantly higher after sugarcane juice than after the sports drink, and higher after both than after water.

One limit deserves stating. The NHS names fruit juices, vegetable juices and smoothies, and does not name sugarcane juice specifically. The category fit is a reasonable reading rather than a direct statement about this drink.

What Is the Best Time to Drink Sugarcane Juice?

No retrieved source sets a best time, and that is worth saying plainly before the two timings that sources do support.

The NHS advises drinking juice with a meal rather than between meals, because doing so reduces the risk of tooth decay. It also advises limiting unsweetened juice to no more than 150 ml a day.

The second timing is around exercise. The cycling trial gave sugarcane juice during and after exertion. Its conclusions about rehydration and glycogen apply to that setting rather than to a drink taken casually through the day.

Morning, empty stomach and bedtime claims circulate widely for this drink. None of them could be traced to a source that could be opened for this article.

What Are the Side Effects of Sugarcane Juice?

The effects follow from the sugar rather than from the cane. The NHS states that eating too much sugar can cause weight gain and tooth decay, and its tooth decay advice applies to juices specifically.

A sharp rise in blood glucose is the other documented effect, recorded in the cycling trial in healthy young athletes. That trial was not designed to describe what happens in people with diabetes.

The trial also names what it could not measure, including serum electrolyte status and blood lactate during exercise. A short trial in 15 athletes is not a safety study.

Is Roadside Sugarcane Juice Safe to Drink?

This is where the Indian evidence is strongest, and it is not reassuring. A 2011 study in the Journal of Laboratory Physicians[4] tested 30 sugarcane juice samples from roadside vendors in Rohtak, Haryana, and found 27 of the 30 contaminated.

It reported enterococci in 55.5% of samples and Escherichia coli in 48.1%, alongside Citrobacter, Klebsiella and Enterobacter species. Its authors read that pattern as faecal contamination. They traced it to bare hands used for handling ice and sieving, and to utensils washed by dipping in the same water.

A 2020 Delhi study in the International Journal of Environmental Research and Public Health[5] found the same problem and added a further one. Bacteria isolated from street fruit drinks showed complete resistance to ampicillin and cefotaxime. It also reported that about 95% of vendors used municipal water and 80% bought ice from local vendors.

The contamination is a hygiene problem rather than a property of sugarcane. Both sets of authors call for hygiene standards among vendors rather than avoidance of the drink itself.

Who Should Be Careful with Sugarcane Juice?

The cautions follow the two themes above, the sugar and the preparation.

Situation	What to do
Diabetes or raised blood sugar	Discuss it with a doctor or pharmacist. Sugarcane juice raised blood glucose more than a sports drink did in the cycling trial.
Managing weight	Count it as free sugars. The NHS sets an adult limit of 30 g of free sugars a day and advises no more than 150 ml of unsweetened juice.
Dental problems or sensitivity	The NHS advises taking juice with a meal rather than between meals, to reduce the risk of tooth decay.
Buying from a roadside vendor	Consider how the ice, water and utensils are handled. The Rohtak study found contamination in 27 of 30 samples and linked it to those three things.
Young children and anyone unwell	The NHS free sugars limits are lower for children, running from 10 g a day at age one to 24 g at ages 7 to 10.

FAQs

Q. Is fresh sugarcane juice different from a canned sugarcane drink?

Yes, and the label shows it. The packaged drink recorded in the USDA database declares 3.4 g of added sugars in a 350 ml can, so it is not simply pressed cane. Fresh juice and a canned product are different drinks, and figures for one do not describe the other.

Q. Why does sugarcane juice raise blood glucose so quickly?

Because of what it is mostly made of. A 2019 analysis in Molecules[6] found sucrose accounted for about 66% by mass of all the metabolites it identified in sugarcane juice. A drink dominated by a simple disaccharide reaches the bloodstream faster than the same sugar held inside plant fibre.

Q. Does sugarcane juice contain antioxidants?

It contains phenolic compounds, measured in a laboratory rather than in people. The Molecules analysis put the total phenolic content of the juice at 93 mg GAE per 100 g and identified flavonoids including apigenin, luteolin and vitexin. Those activities were tested in test-tube assays only, with no human or animal work.

Q. How does one glass compare with the daily sugar limit?

The two figures are worth holding together. The trial composition gives 9.1 g of carbohydrate in every 100 g of juice, and the NHS sets the adult free sugars limit at 30 g for a whole day. A tall glass is not a small contribution to that total.

Q. Does boiling or pasteurising make roadside juice safer?

The studies point at the handling rather than the cane. Both Indian studies traced contamination to ice, municipal water, utensils and bare hands, and the Rohtak authors cite foodborne outbreaks linked to unpasteurised juices. Heat treatment addresses only part of a problem that begins with the ice and the glass.

Q. Is sugarcane juice a good drink in hot weather?

The trial is more cautious than the reputation. Its authors limited their rehydration conclusion to exercise in a comfortable environment below 30 degrees Celsius, and they state they could not assess serum electrolyte status at all. Indian summer conditions sit well outside what that study tested.
