People searching for "how much sugar per day" are sometimes asking about blood sugar rather than the sugar they eat. That is a different question with a different answer, and it has its own short section near the end.
How much sugar per day is safe for an adult?
Less than 50 g of free sugars a day for an adult eating about 2,000 kcal, and ideally less than 25 g. Those figures come from the WHO's 2015 guideline, which made a strong recommendation to keep free sugars below 10 per cent of total energy and a conditional one to go below 5 per cent. The limits scale with how much you eat, so someone on 1,600 kcal would aim for under 40 g, or under 20 g for the stricter target. There is no minimum. Starchy foods supply all the glucose the body needs, and the liver can make more when required.
How many teaspoons of sugar a day is that?
About six level teaspoons at the stricter 25 g limit, and about 12 at the 50 g ceiling, taking a level teaspoon of granulated sugar as roughly 4 g. A heaped teaspoon, the way most people spoon sugar into tea, holds closer to 6 to 8 g, so the real count runs lower than it looks: four heaped spoons can finish the stricter allowance for the day. Counting in teaspoons is imperfect, but it turns the grams on a packet into something you can picture.
What counts as free sugar?
Free sugars are the sugars added to food and drink by a manufacturer, a cook or you, plus the sugars naturally present in honey, syrups and fruit juice. So white sugar, brown sugar, jaggery, khandsari, honey, date syrup and liquid glucose all count, whatever their colour or reputation. The comparison of jaggery, honey or sugar explains why the traditional sweeteners get no exemption. Fruit juice counts even when the pack says 100 per cent fruit with no added sugar, because pressing frees the sugar from the cell walls that held it in the whole fruit.
Does the sugar in fruit and milk count?
No. The sugars inside whole fruit and vegetables, and the lactose naturally present in plain milk and curd, are not free sugars, and the WHO limit does not apply to them. There is no evidence that whole fruit causes the harms linked to added sugar; the fibre, the chewing and the water all slow it down and fill you up. A 250 ml glass of plain milk carries about 12 g of lactose and still counts as zero free sugar. Stir in two spoons of sugar or a sweetened malt powder, and those grams count in full.
How much sugar is in a cup of chai?
Two level teaspoons of sugar in a cup of chai add about 8 g of free sugar, a third of the stricter daily limit. Three such cups across the day come to 24 g, which on their own use up the 25 g target before anything else sweet is eaten. Going from two teaspoons to one halves the figure, and many people find that less sweet tea stops tasting flat after a few weeks of sticking with it.
How much sugar is in a bottle of cola or packaged juice?
A 300 ml bottle of regular cola carries roughly 30 g of sugar or more, above the stricter daily limit in a single drink. Regular colas and most fizzy drinks run at around 10 g of sugar per 100 ml. Packaged fruit juices and fruit drinks sit in a similar range, often 10 to 15 g per 100 ml, so a 200 ml carton gives around 20 to 30 g. Drinks are the easiest way to overshoot, because they do not register as food and do little for hunger.
Where else does sugar hide in Indian food?
In biscuits, flavoured yoghurt, breakfast cereals, sauces and much of what is sold as a health drink. Cream and sweet biscuits are often a quarter to a third sugar by weight, so a few with tea can add 10 g or more. A small cup of flavoured yoghurt may carry two teaspoons or so of added sugar on top of the milk's own lactose. Tomato ketchup is roughly a fifth to a quarter sugar, close to a teaspoon in every tablespoon.
| Item | Free sugar |
|---|---|
| Cup of chai with two level teaspoons | about 8 g |
| 300 ml bottle of regular cola | roughly 30 g or more |
| 200 ml carton of packaged juice | around 20 to 30 g |
| A few cream or sweet biscuits with tea | 10 g or more |
| One syrup-soaked gulab jamun or rasgulla | most of the day |
A level teaspoon is about 4 g, but the heaped spoon most people use holds closer to 6 to 8 g.
How do you spot added sugar on a food label?
Look for the added sugars line in the nutrition panel, then read the ingredients list. Most packaged foods sold in India now show added sugar separately from total sugar, which lets you tell a plain curd's lactose from a flavoured one's sweetening. In the ingredients, sugar appears under many names: sucrose, invert syrup, liquid glucose, dextrose, fructose, corn syrup, honey, jaggery and fruit juice concentrate. Ingredients are listed by weight, so a sugar near the top of the list, or several different sugars spread through it, is a reliable warning sign.
How much sugar is in Indian sweets?
A lot, concentrated into small pieces. A single syrup-soaked sweet such as a gulab jamun or rasgulla can carry most of a day's 25 g, depending on its size and how much syrup comes with it, and barfi, laddoo and halwa are often a third or more sugar by weight. None of this puts mithai off limits at a wedding or during Diwali. It means one piece is the portion, and the second takes the day past the limit. Calories in Indian sweets goes through the common ones piece by piece.
Does ICMR recommend a sugar limit for Indians?
Yes. ICMR-NIN's Dietary Guidelines for Indians, revised in 2024, advise keeping sugar intake low and cutting back on sugary drinks and on ultra-processed foods high in fat, sugar and salt. Their advice points the same way as the WHO's, and the practical message is identical: most of the day's sweetness should come from whole fruit, not from the sugar bowl or a packet.
Do children need less sugar?
Yes, in absolute terms, because they eat fewer calories. The WHO percentages apply to children as well, so a child eating 1,400 kcal a day would aim for under 35 g of free sugar and ideally under about 18 g. Many paediatric bodies advise no added sugar at all before the age of two. Replacing the juice carton with whole fruit, and flavoured milk with plain, does much of the work.
Does eating sugar cause diabetes?
Not directly, but a high intake raises the risk. Type 2 diabetes develops from a mix of genes, excess body fat, inactivity and diet, and sugar contributes mainly through the extra calories it adds without filling you up. Sugary drinks stand out: large pooled analyses of cohort studies have linked a regular sugary-drink habit to a higher risk of type 2 diabetes, only partly explained by weight gain.
Is sugar intake the same as blood sugar?
No. Dietary sugar is what you eat; blood sugar is the glucose circulating in your blood, which the body holds in a fairly narrow range whatever you eat, unless something has gone wrong. By American Diabetes Association criteria, a fasting blood glucose of 70 to 99 mg/dL is normal, 100 to 125 mg/dL indicates prediabetes, and 126 mg/dL or more, confirmed on a repeat test, indicates diabetes. A reading above normal is a reason to see a doctor, not to cut sugar quietly and hope. The prediabetes diet guide covers eating once a result lands in that middle band.
How do you cut sugar without feeling deprived?
Start with drinks, then the daily habits, and leave festival sweets for last. Halve the sugar in tea over a fortnight, swap packaged juice for whole fruit, and choose plain curd with fruit stirred in over flavoured yoghurt. Moving to jaggery or honey changes nothing, and artificial sweeteners are a separate debate, covered in are sugar-free sweeteners safe. Learning to read everyday food choices like this is the heart of NNWA's Healthy Eating and Everyday Wellness course, a three-week beginner course at 3,499 rupees, reduced from 5,999, with an NNWA certificate.
Cutting sugar in the order that sticks
Drinks first, daily habits second, festival sweets last. Starting at the other end is what makes people give up in a fortnight.
Start with what you drink
Cola and packaged juice do little for hunger, so they are the easiest thing to remove and the least missed once they are gone.
Halve the chai
Going from two level teaspoons to one takes a cup from about 8 g to about 4 g. Do it across a fortnight and the tea stops tasting flat.
Swap juice for the whole fruit
The sugar then arrives inside the fruit, held by fibre and water, which puts it outside the limit and fills you up on the way.
Fix the daily packets
Plain curd with fruit stirred in rather than a flavoured tub, and biscuits treated as a sweet rather than as something tea comes with.
Leave mithai until last
One piece is the portion at a wedding or at Diwali, and the second takes the day past the limit. Nothing here has to be given up for good.
The day's sugar, summed up
Aim for under 25 g of free sugar a day, about six level teaspoons, and treat 50 g as the ceiling. Chai, soft drinks, packaged juice, biscuits and mithai supply most of it in Indian homes, while whole fruit and plain milk do not count at all. Read the added-sugar line before you buy, cut the drinks first, and keep blood sugar numbers for the conversation with your doctor.
