Is eating 50g of sugar a day too much?

Sugar is a common part of many people’s diets, but how much is too much? Consuming too much added or free sugar can negatively impact health. This article examines whether eating 50 grams of sugar per day is excessive.

What is considered excessive sugar intake?

The World Health Organization (WHO) recommends limiting added or free sugars to less than 10% of total calorie intake. For a normal 2,000 calorie diet, this equates to around 50 grams of sugar per day. The American Heart Association advises a more strict daily limit of no more than 25 grams (6 teaspoons) for women and 36 grams (9 teaspoons) for men. So by these standards, consuming 50 grams per day would be considered very high.

Are all sugars created equal?

While naturally occurring sugars like those in fruit and milk are fine in moderation, added or free sugars like table sugar, syrups, and those used in processed foods are more concerning. Our bodies handle added and natural sugars differently. Foods high in added sugars tend to be low in overall nutrition.

What are the downsides of excessive sugar consumption?

Eating too much added sugar has been linked to increased risk for:

– Obesity and weight gain
– Heart disease
– Type 2 diabetes
– High blood pressure
– High cholesterol and triglycerides
– Liver disease
– Cavities and dental issues
– Cognitive decline and dementia

Excess sugar can also lead to energy crashes, inflammation, and nutrient deficiencies. The more you eat, the more your tastebuds adapt, fueling sugar cravings and overeating.

How Much is 50 Grams of Sugar?

To understand how easy it is to consume 50 grams of sugar, let’s look at some common sources:

Sugary Drinks

– 1 can (12oz) of soda: 39g of sugar
– 1 grande Starbucks Bottled Mocha Frappuccino: 50g of sugar
– 1 bottle (20oz) of Vitaminwater: 32g of sugar

Sugary Foods

– 1/2 cup Ben & Jerry’s Chocolate Fudge Brownie Ice Cream: 21g of sugar
– 1 cup Kellogg’s Froot Loops: 12g of sugar
– 1 regular size Snickers bar: 27g of sugar
– 1/2 cup Jif Extra Crunchy Peanut Butter: 17g of sugar
– 1 packet of Yoplait Strawberry Yogurt: 24g of sugar

As you can see, just 1-2 sugary drinks or treats can quickly add up to 50 grams.

Daily Sugar Recommendations

Here are some expert daily sugar intake recommendations for adults:

Organization Recommended Limit
American Heart Association 25 grams (6 tsp) for women
36 grams (9 tsp) for men
World Health Organization 50 grams (12 tsp)
US Dietary Guidelines 25 grams (6 tsp) for women
38 grams (9.5 tsp) for men

As you can see, most major health organizations recommend limiting added sugar to between 25-50 grams per day. Consuming more than these amounts is considered excessive and unhealthy.

Tips to Reduce Sugar Intake

Here are some tips to cut down on added sugars:

– Drink water or unsweetened coffee or tea instead of sugary beverages
– Gradually reduce sugar to train your tastebuds
– Limit fruit juice and dried fruit which are high in natural sugars
– Check labels and choose low or no sugar added foods
– Eat more whole foods like fruits, vegetables, lean protein, whole grains, nuts and seeds
– Sweeten recipes with spices like cinnamon, vanilla, almond extract
– Satisfy sweets cravings with a small portion of dark chocolate (70% cocoa or higher)
– Avoid sugary sauces, dressings, condiments, and spreads

Health Effects of Consuming Too Much Sugar

Eating too much added sugar on a regular basis can take a toll on physical and mental health. Here is an overview of the research:

Obesity, Fatty Liver & Diabetes

Excess sugar is easily converted to fat by the liver, leading to weight gain over time. In a review of 68 studies, sugar-sweetened beverages were linked to obesity and type 2 diabetes. The excess calories from sugar overload the liver, causing non-alcoholic fatty liver disease. Over 90% of people with fatty liver also have insulin resistance or diabetes.

Cardiovascular Disease

People who consumed more than 25% of daily calories from added sugar had a nearly three times higher risk of dying from cardiovascular disease compared to those who consumed less than 10%, according to a 2014 study with over 30,000 participants. Too much sugar can raise blood pressure, alter cholesterol levels, and cause plaque buildup in the arteries.


While more research is needed, some studies link high sugar diets to increased cancer risk and progression. One study found that women who consumed high amounts of sugar-sweetened beverages had an 87% higher risk of cervical cancer. Another study showed that mice fed a diet high in simple sugars had increased rates of breast cancer.

Cognitive Decline

A 2018 study followed over 5,000 people for 20 years and found that those with higher sugar intake had poorer memory, smaller brain volume, and a faster rate of cognitive decline. Too much sugar can damage neurons and contribute to inflammation in the brain.

Depression & Mood Disorders

Eating lots of added sugar may increase risk for depression and anxiety. One study found men who consumed high amounts had a 23% higher chance of developing depression or anxiety within 5 years compared to those who ate little. Blood sugar spikes and crashes can negatively impact mood.


Research shows sugar stimulates the brain’s reward pathways similarly to addictive drugs. Animal studies show sugar dependence and withdrawal. Rats given access to sugar for several weeks showed signs of high motivation for sugar comparable to addiction.

Does Cutting Sugar Help with Weight Loss?

Reducing added sugar intake almost invariably results in some weight loss. Here’s an overview of how lowering sugar consumption helps:

– Fewer empty calories: Sugary foods and drinks pack in calories but lack nutrition. Cutting back reduces excess calorie intake that would otherwise be stored as fat.

– Reduced appetite: The brain doesn’t register liquid sugar calories in the same way as solid foods. This results in decreased satiety and overeating. Studies show higher sugar intake is linked to increased food consumption.

– Less insulin resistance: Excess sugar spikes insulin, causing cells to become resistant over time, resulting in weight gain and diabetes. Lowering sugar improves insulin sensitivity.

– Less fat production: Sugar signals the liver to convert excess calories to fatty acids. Less sugar means lower rates of de novo lipogenesis (DNL).

– Improved leptin response: Leptin is a hormone that regulates appetite and fat burning. Too much sugar can impair leptin signaling, increasing hunger levels.

– Healthier food choices: People naturally begin choosing more nutritious whole foods over sugary processed options when limiting added sugars.

However, sugar alone doesn’t tell the whole weight loss story. Total calorie intake, nutrition, and lifestyle factors also play key roles. But lowering added sugar is a solid strategy to create a calorie deficit and boost weight loss.

How Much Weight Loss is Reasonable by Cutting Sugar?

Most studies show a reduction of added sugars equating to about 1 pound (0.5 kg) of weight loss per week. However, effects vary based on how much sugar is currently consumed, calorie deficit created, diet quality, physical activity, and other factors influencing metabolism and hunger levels.

For example, a person consuming 400 calories per day from sugary beverages who cuts that down to 100 calories could expect more rapid initial weight loss compared to someone decreasing from 150 to 100 calories.

Overall, cutting back on added sugars by 25-50 grams per day can be a helpful part of a comprehensive weight loss regimen. But lowering total calories via a nutritious, balanced diet plus exercise provides the best results.

Tips for Living Low Sugar

Here are 10 tips to reduce added sugars without feeling deprived:

1. Quit Soda and Sugary Drinks

Cutting out beverages like soda, energy drinks, juice, and specialty coffee and tea drinks can slash a significant source of unnecessary calories and sugars. Drink water, unsweetened tea, coffee, or mineral water instead. Slowly wean yourself off sugary drinks to prevent withdrawal symptoms.

2. Limit Condiments, Sauces, and Dressings

Many sauces, condiments, and salad dressings are hidden sources of added sugars. Make your own dressings from vinegar, olive oil, and spices or choose low sugar varieties. Skip the ketchup and barbecue sauce which can contain up to 4 grams per tablespoon.

3. Choose Low Sugar Yogurt

Flavored yogurts can contain 20+ grams of added sugars. Opt for plain Greek yogurt and add fresh fruit, nuts, seeds, and spices to control sweetness. Read labels and pick yogurts with no more than 6 grams of sugar per serving.

4. Make Desserts a Rare Treat

Reduce expectations that dessert needs to be part of every meal. When enjoyed occasionally, a modest portion of cake, ice cream, or cookies is fine for most healthy diets. Fruit, yogurt, or small squares of dark chocolate make healthier daily treats.

5. Check Cereal and Breakfast Bars

Many pre-sweetened cereals and breakfast bars are loaded with sugar, some upwards of 12 grams per serving. Opt for unsweetened oatmeal, granola, muesli or whole grain cereals under 5 grams of sugar per serving.

6. Limit Fruit Juice

Fruit juice packs in the fructose, a simple sugar. An 8 ounce glass has 24 grams of sugar and lacks fiber. Eat whole fruits or add lemon/lime wedges to water instead. Limit juice portions or dilute it 50/50 with water.

7. Avoid Agave, Honey, and Maple Syrup

Although they sound wholesome, these popular “natural” sweeteners are almost pure sugar. Use sparingly, just like white sugar. Try cinnamon, vanilla, mint, or fruit infused water for subtle sweetness instead.

8. Check Labels for Sugar Varieties

Ingredients like evaporated cane juice, cane crystals, corn sweetener, crystalline fructose, maltose, and more are added sugars by another name. Limit foods with multiple sugar varieties.

9. Skip the Frappuccinos & Sweet Tea

Blended coffee and tea drinks are teeming with sugar. A 16 ounce Strawberries & Crème Frappuccino has 75 grams – yikes! Sweet tea can have over 44 grams per glass. Try plain iced coffee or tea sweetened subtly with stevia instead.

10. Satisfy Cravings with Fruit

Turn to fresh fruit when you want something sweet. Berries, pineapple, melon, grapefruit, and peaches make ideal alternatives to sugar-laden desserts. Unsweetened applesauce cups or banana “nice” cream can also hit the spot.

Healthy Sugar Substitutes

To satisfy a sweet tooth without all the negative effects of sugar, try these natural sugar alternatives:


Stevia comes from the leaves of a South American plant. It contains no calories and does not raise blood sugar. Use powdered or liquid stevia to sweeten drinks and recipes.

Monk Fruit Extract

Monk fruit gets its sweetness from antioxidants called mogrosides. Try monk fruit sweetener in smoothies or tea. Beware blends with added sugar or artificial sweeteners.


Erythritol is a sugar alcohol derived from corn. It provides about 70% the sweetness of sugar with 95% less calories. It does not spike blood sugar but may cause digestive issues in large doses.


Xylitol is a sugar alcohol sourced from birch trees and corn cobs. It has 40% fewer calories than sugar and is safe for diabetics. Use sparingly, as it may have laxative effects.

Yacon Syrup

Yacon syrup comes from the yacon plant native to South America. It is high in fructooligosaccharides which provide sweetness but minimal calories and no sugar spike.


Dates offer a rich sweetness. Blend them into smoothies or make homemade date syrup to use instead of refined sugar in recipes. Soak dates first to soften.


Consuming 50 grams or more of added sugars daily qualifies as excessive intake by most health authorities. While naturally occurring sugars like those in fruit and dairy are fine in moderation, added sugars provide empty calories and too much fructose, negatively impacting health and weight.

Limiting added sugar to 25 grams per day for women and 38 grams for men is ideal, but striving for under 100 grams total sugars including natural sources is a good goal. Reading labels, avoiding sugary beverages, and focusing on whole foods makes reducing intake much more manageable. Including healthy fats, protein, and fiber at meals also minimizes cravings for sweets.

Cutting back on unnecessary added sugars can promote weight loss, improve energy, regulate appetite, and reduce disease risk when paired with an overall balanced nutrition plan. But added sugars alone don’t tell the whole story. Make sure to emphasize whole, minimally processed foods over refined grains, unhealthy fats, and excess calories in your diet and lifestyle habits for optimal health.
