Sweet Tooth is a Netflix sci-fi thriller about Gus, a young human-deer hybrid whose world changes after a devastating viral pandemic.The new sci-fi thriller is based on the comic series of the same name created by Jeff Lemire. The Netflix eight-episode series follows a young boy, Gus, who is part human and part deer. Set in the not-too-distant future, it takes place in a post-apocalyptic United States after a devastating viral pandemic. The disease decimated the world’s population, while children began to be born with human and animal hybrid characteristics. As someone who enjoys binging a show while cozied up in front of the TV, I found its mix of mystery, adventure, and emotional storytelling easy to follow. The story also shows why people are afraid of hybrids and believe they may be the cause of the virus.
The story becomes more personal after Gus’s father is killed, pushing the young deer hybrid to embark on a quest to find his mother. Christian Convery plays Gus, while Nonso Anozie plays Tommy Jeppard, a traveler and loner who becomes an important companion. Their relationship develops through trust, friends, and shared hopes. The journey becomes harrowing as Gus searches for the truth about his origins and the sickness affecting the world. In the final chapter, the characters continue discovering more about the hybrid mystery, the possible cure, and the possibility of curing the Sick.
The story also has an important publication history. The collected editions of Lemire’s comics were originally published in single magazine form, including Sweet Tooth #1-40 and Sweet Tooth: The Return #1-6 from DC Comics. Readers can find the issues in different format options, including trade paperbacks and a two-in-one Deluxe Edition. The magazine and later collected edition formats offer different ways to explore the story beyond the television show.
What Is a Sweet Tooth?
A sweet tooth is a strong preference for sweet-tasting foods and drinks. It isn’t a medical diagnosis. Someone with a sweet tooth might enjoy desserts regularly, while another person might simply prefer sweet flavors without eating many sugary foods.
A sweet tooth also differs from a sugar craving. A preference is fairly general. A craving is more specific and can feel urgent.
For example, you might enjoy sweet foods in general. However, you might occasionally find yourself thinking specifically about chocolate, ice cream, cookies, or a sweet coffee. That more focused desire is a craving.
Sweet Tooth vs. Sugar Craving
| Sweet tooth | Sugar craving |
| General preference for sweet flavors | Strong desire for a particular sweet food or drink |
| Can exist without hunger | Can appear when you’re hungry or already full |
| May simply reflect food preference | Often involves habits, cues, emotions, or routines |
| Isn’t a medical condition | Isn’t automatically a sign of addiction or illness |
Cravings can also occur when you aren’t physically hungry. Food cues, memories, routines, emotions, and the rewarding qualities of certain foods can all influence what you want to eat.
Is Having a Sweet Tooth Normal?
Yes. Enjoying sweet flavors is common.
The important question isn’t simply whether you like dessert. Instead, look at the overall pattern. A sweet food can fit into an otherwise varied diet. Problems become more relevant when foods and beverages high in added sugar regularly displace more nutrient-dense choices or contribute substantial amounts of added sugar.
The current Dietary Guidelines for Americans, 2025–2030 emphasize diets built around nutrient-dense foods such as protein, dairy, vegetables, fruits, healthy fats, and whole grains while recommending less highly processed food and added sugar.
What Causes a Sweet Tooth and Sugar Cravings?
There isn’t one universal cause of sugar cravings. Several factors can overlap, which explains why the same person might crave sweets for completely different reasons on different days.
The Brain’s Reward System
Sweet foods can be rewarding because the brain responds to pleasurable eating experiences through systems involved in motivation, learning, and reward.
That doesn’t mean every craving represents an addiction. It means your brain can learn that a particular food feels rewarding and then encourage you to seek it again.
Think about popcorn at a movie theater. After enough repetitions, the setting itself can become a cue for wanting popcorn. The same process can happen with dessert after dinner.
The craving may become part of the routine before you consciously decide whether you’re actually hungry.
Learned Food Habits
Habits can turn a simple preference into an automatic routine.
Suppose you eat a cookie every afternoon while doing homework. After repeating that pattern many times, sitting down to study may become associated with wanting a cookie.
The food doesn’t necessarily cause the situation. Instead, your brain learns the connection between the cue and the reward.
Common examples include:
- Dessert after dinner
- Chocolate during stressful moments
- Candy while watching television
- Sweet coffee during an afternoon slump
- Ice cream during weekend movie nights
- A sugary snack after finishing school or work
Changing the routine can sometimes reduce the craving because you’re removing part of the learned association.
Food Cues and Availability
Your surroundings matter more than many people realize.
A brightly packaged candy bar near a checkout counter can catch your attention before you’ve consciously decided you want one. The smell of freshly baked cookies can do the same thing.
Advertising, food packaging, restaurant menus, social events, and simply having sweets within easy reach can all act as food cues.
That is why managing cravings isn’t only about willpower. Your environment can influence what you notice and what you reach for.
Hunger and Long Gaps Between Meals
Sometimes what feels like a sugar craving is simply hunger wearing a sweet disguise.
If you go a long time without eating, a highly palatable food can become especially appealing. Sweet foods are often convenient and enjoyable, which makes them an easy choice when you’re very hungry.
A more satisfying meal or snack can help because it addresses the underlying hunger rather than merely trying to suppress the desire for something sweet.
Stress, Emotions, and Comfort Eating
Food can become connected to emotions.
Someone might reach for chocolate after a stressful day. Another person might want ice cream when bored. Someone else might snack while watching a favorite show simply because that activity has always included food.
These patterns don’t mean a person lacks self-control. They show how eating can become connected to comfort, routine, reward, and emotional experiences.
If you notice this pattern, it can help to ask:
- Am I physically hungry?
- Am I looking for comfort?
- Am I bored?
- Did something stressful happen?
- Is this craving connected to a particular routine?
- Have I eaten enough recently?
That short pause can make an automatic habit more noticeable.
Sleep and Daily Routine
Sleep and routine can also influence eating behavior. Poor sleep can affect appetite and food choices, while irregular schedules can make regular meals harder to maintain.
The CDC lists inadequate or poor-quality sleep among factors associated with unhealthy eating patterns and excess weight gain.
The takeaway isn’t that one bad night creates a sweet tooth. Instead, sleep belongs in the larger picture of appetite, energy, routine, and food choices.
Restrictive Eating and Food Deprivation
Extreme food rules can make certain foods occupy even more mental space.
If you tell yourself that a favorite food is completely forbidden, you may spend more time thinking about it. A more sustainable approach usually focuses on building balanced eating habits and reducing excess added sugar rather than creating fear around every sweet food.
You don’t need to treat fruit, milk, or an occasional dessert as though they’re all the same thing.
Are Sugar Cravings the Same as Sugar Addiction?
The phrase “sugar addiction” appears frequently online, but it can oversimplify a complicated subject.
A craving involves a strong desire for food. A habit involves repeated behavior. Reward learning involves the brain connecting particular foods or situations with positive experiences. Substance addiction is a more specific clinical concept.
Those ideas shouldn’t automatically be treated as interchangeable.
If you frequently crave sweets, that doesn’t by itself prove that you’re addicted to sugar. It may reflect hunger, habit, environmental cues, emotions, food preferences, or several factors working together.
A better question is often:
What is triggering this craving, and what pattern surrounds it?
That question leads to something useful. You can identify whether the trigger is hunger, routine, stress, boredom, availability, or another factor.
Natural Sugar vs. Added Sugar: What’s the Difference?
One of the most important distinctions in any discussion about a sweet tooth and sugar intake is the difference between natural and added sugars.
Naturally occurring sugars are part of foods such as whole fruit and milk. Added sugars are introduced during processing or preparation.
The FDA explains that added sugars include sugars added during food processing, table sugar used as a sweetener, syrups, honey, and sugars from concentrated fruit or vegetable juices. Naturally occurring sugars in fruits, vegetables, and milk aren’t classified as added sugars.
Examples of Naturally Occurring Sugar
- Apples
- Oranges
- Berries
- Bananas
- Milk
- Plain yogurt without added sweeteners
These foods also provide other nutrients. Whole fruit, for example, provides fiber along with its natural sugars.
Examples of Added Sugar
- Regular soda
- Candy
- Cakes
- Cookies
- Ice cream
- Sweetened breakfast cereals
- Sweetened coffee
- Sweetened tea
- Many packaged desserts
The distinction becomes especially useful when reading a Nutrition Facts label.
Common Names for Added Sugar
Sugar doesn’t always appear on an ingredient list simply as “sugar.”
You may also see:
- Sucrose
- Dextrose
- Glucose
- Fructose
- Corn syrup
- High-fructose corn syrup
- Cane sugar
- Brown sugar
- Honey
- Maple syrup
- Molasses
- Fruit juice concentrate
- Malt syrup
Honey and maple syrup may sound more natural than table sugar. However, when they’re added to a food or beverage as sweeteners, they count as added sugars under FDA labeling rules.
Where Most Added Sugar Comes From
For many people, the biggest sources aren’t mysterious. They’re foods and drinks that taste noticeably sweet.
The CDC identifies sugar-sweetened beverages, desserts, and sweet snacks as leading sources of added sugar in the U.S. diet.
| Source | Examples | Why it can add up |
| Sugary drinks | Soda, sweet tea, sports drinks | Sugar is easy to drink quickly |
| Sweetened coffee | Flavored lattes, sweet creamers | Added sugar can hide in beverages |
| Desserts | Cakes, cookies, pies | Often contain concentrated added sugar |
| Candy | Gummies, chocolate, hard candy | Small portions can contain substantial sugar |
| Breakfast foods | Sweet cereal, pastries | Sugar can appear in foods eaten daily |
| Sweetened dairy | Flavored yogurt, milk drinks | Sugar may come from added sweeteners |
| Snack foods | Bars, granola products | “Healthy” marketing doesn’t guarantee low added sugar |
Why Sugary Drinks Deserve Special Attention
Liquid sugar can be surprisingly easy to consume.
According to the CDC, a 12-ounce regular soda contains more than 10 teaspoons of added sugar, or about 42 grams, which provides roughly 150 calories from sugar.
That makes beverages an especially practical place to look if you’re trying to understand where your added sugar comes from.
You don’t necessarily need to overhaul everything at once. Simply noticing how often you drink sweetened beverages can reveal a major pattern.
Health Effects of Eating Too Much Added Sugar
A sweet tooth itself isn’t a disease. The health concern comes from regularly consuming too much added sugar, especially when it contributes excess calories or replaces more nutritious foods.
Weight and Overall Energy Intake
Added sugar contributes calories without providing the same range of nutrients found in nutrient-dense foods.
If sugary foods and drinks become a large part of your usual eating pattern, they can make it harder to build a balanced diet.
That doesn’t mean one cookie, soda, or dessert causes a health problem. Overall dietary patterns matter far more than one food eaten occasionally.
Blood Sugar and Type 2 Diabetes
Added sugar deserves attention when discussing type 2 diabetes, but the relationship isn’t as simple as “sugar causes diabetes.”
Type 2 diabetes develops through multiple interacting factors. Diet, physical activity, genetics, body composition, sleep, and other factors can all contribute to risk.
The CDC states that consuming too much added sugar can contribute to health problems including type 2 diabetes and heart disease. It also specifically identifies frequent sugar-sweetened beverage consumption as being associated with type 2 diabetes.
That distinction matters. A single sugary food isn’t a diagnosis.
Heart Health
High intake of added sugar can also fit into dietary patterns associated with cardiovascular health concerns.
The American Heart Association recommends limiting added sugar and notes that the major sources in the U.S. diet include sugary beverages, desserts, sweet snacks, and sweetened coffee or tea.
Reducing excess added sugar can therefore be one part of a broader heart-healthy eating pattern.
Dental Health and Cavities
Your teeth experience repeated exposure to dietary sugars.
Frequent consumption of sugary foods and drinks can increase the conditions that contribute to tooth decay and cavities. The CDC identifies tooth decay and cavities among health concerns associated with frequent consumption of sugar-sweetened beverages.
Frequency matters here. Sipping sweet drinks throughout the day can repeatedly expose teeth to sugar.
Liver and Metabolic Health
Sugar-sweetened beverages have also been associated with metabolic health problems, including non-alcoholic fatty liver disease.
The CDC lists non-alcoholic liver disease among health conditions associated with frequent sugar-sweetened beverage consumption.
Again, this is about dietary patterns and associations rather than a claim that every person who consumes sugar will develop liver disease.
Signs Your Sweet Tooth May Be Affecting Your Eating Habits
A sweet tooth becomes more worth examining when it starts shaping your daily routine.
Possible signs include:
- Frequently choosing sugary drinks when unsweetened options are available
- Automatically eating dessert after meals
- Snacking on sweets whenever you’re stressed or bored
- Consistently choosing sweet foods over more varied options
- Not realizing how much added sugar appears in drinks and packaged foods
- Feeling that you need something sweet at a particular time every day
- Frequently eating sweets without noticing the portion
- Using desserts as your main way to cope with difficult emotions
None of these signs automatically means something is medically wrong.
They simply give you clues about your eating pattern.
How to Manage Sugar Cravings Without Extreme Restriction
Managing a sweet tooth doesn’t have to mean banning every sweet food from your life.
In fact, extreme rules can make eating unnecessarily stressful. A more practical strategy is to understand why the craving appears and then change the part of the routine that needs attention.
Start With Regular, Balanced Meals
If you’re hungry, trying to “outsmart” hunger with willpower isn’t a very useful strategy.
Build meals around a variety of foods, including protein foods, vegetables, fruits, whole grains, dairy or suitable alternatives, and healthy fats.
A satisfying meal can make it easier to distinguish genuine hunger from a craving that comes mainly from habit.
For example, a meal containing eggs, whole-grain toast, fruit, and yogurt provides a different mix of nutrients than a breakfast consisting mainly of a sweet pastry.
The goal isn’t perfection. It’s variety and satisfaction.
Choose Fruit When You Want Something Sweet
Whole fruit can be an easy way to enjoy a naturally sweet flavor while also getting fiber and nutrients.
Try:
- Berries with plain yogurt
- Apple slices with peanut butter
- Banana with oatmeal
- Orange slices after a meal
- Frozen berries as a cold snack
Fruit doesn’t need to be treated as a “bad sugar.” Its naturally occurring sugar is different from added sugar.
Rethink Sugary Drinks
If you want one practical place to start, look at beverages.
The CDC recommends choosing water instead of sugary drinks and suggests options such as sparkling water, unsweetened coffee or tea, and other drinks without added sugar.
Consider simple changes:
- Soda → sparkling water
- Sweet tea → unsweetened tea
- Flavored coffee → coffee with less or no added syrup
- Sweetened water → plain or naturally flavored water
- Energy drink → an unsweetened beverage appropriate for your age and needs
A gradual change can be easier than suddenly changing every drink you have.
Read the Nutrition Facts Label
The Nutrition Facts label gives you a straightforward way to see how much added sugar a packaged food contains.
Pay attention to:
- Serving size
- Total sugars
- Added sugars
- % Daily Value
The FDA currently uses 50 grams of added sugar per day as the Daily Value on Nutrition Facts labels based on a 2,000-calorie diet. The FDA also considers 5% DV or less to be low and 20% DV or more to be high for a nutrient.
Remember that the Daily Value is a labeling reference. Individual needs can differ.
Make Sweet Foods Less Automatic
You don’t have to rely entirely on willpower.
Change the environment around the habit.
For example:
- Keep fruit visible and easy to reach.
- Don’t keep large quantities of favorite sweets immediately beside your study or work area.
- Avoid automatically pairing television with snacks.
- Keep water nearby.
- Put unsweetened foods where you’ll notice them first.
Small environmental changes can interrupt an automatic routine.
Wait Out the Craving
A craving can feel intense without lasting forever.
When one appears, try giving yourself a few minutes before automatically reaching for food. Change activities, drink some water, step outside, talk with someone, or focus on another task.
The goal isn’t to punish yourself for wanting something sweet. It’s simply to create a gap between the craving and the automatic response.
Reduce Added Sugar Gradually
If you currently add several spoonfuls of sugar to a drink, you don’t have to make a dramatic overnight change.
Try reducing the amount gradually.
The same idea works with:
- Sweetened coffee
- Breakfast cereal
- Flavored yogurt
- Dessert frequency
- Sweet sauces
- Packaged snacks
Small changes can become routine because they don’t require you to rebuild your entire eating pattern in one day.
How Much Added Sugar Should You Have?
Current U.S. dietary guidance emphasizes reducing added sugar as part of an overall nutrient-dense eating pattern. The current Dietary Guidelines for Americans, 2025–2030 prioritize whole, nutrient-dense foods and recommend reducing highly processed foods, including those containing added sugars.
For food labels, the FDA’s current Daily Value for added sugars is 50 grams per day based on a 2,000-calorie diet.
The American Heart Association uses a more restrictive recommendation for adults, suggesting no more than 25 grams per day for women and 36 grams per day for men.
These numbers come from different organizations and serve different purposes. They shouldn’t be treated as a personalized prescription.
For children and adolescents, nutrition needs differ by age and development. A pediatrician or registered dietitian can provide individualized guidance when there’s a concern about eating patterns, blood sugar, or nutrition.
Common Foods and Drinks That Can Hide Added Sugar
Sugar isn’t limited to obvious desserts.
It can also appear in foods that don’t taste like candy.
The CDC notes that added sugar may appear in products such as pasta sauce, nut butters, sports drinks, energy drinks, coffee drinks, and iced tea.
Check labels on:
- Flavored yogurt
- Granola
- Breakfast cereal
- Snack bars
- Bottled coffee
- Sweetened tea
- Pasta sauce
- Salad dressing
- Ketchup and other condiments
- Sweetened nut butter
- Packaged smoothies
A Simple Label-Reading Example
Imagine two yogurts.
| Label information | Yogurt A | Yogurt B |
| Total sugars | 15 g | 8 g |
| Added sugars | 7 g | 0 g |
| Naturally occurring sugars | 8 g | 8 g |
Yogurt A contains 15 grams of total sugar, but 7 grams come from added sugar.
Yogurt B contains 8 grams of total sugar with no added sugar.
That is why looking only at total sugars can be misleading. The FDA specifically separates total sugars from added sugars on the Nutrition Facts label.
Healthier Ways to Satisfy a Sweet Tooth
You don’t need to turn every dessert into a “healthy substitute.” Sometimes the most useful change is simply choosing a food that better fits what you’re actually looking for.
| If you usually choose | You could also consider |
| Soda | Sparkling or plain water |
| Sugary cereal | Lower-added-sugar cereal with fruit |
| Sweetened yogurt | Plain yogurt with fruit |
| Candy | Fruit or a smaller serving of a favorite treat |
| Sugary coffee | Coffee with less added syrup |
| Ice cream | Fruit with yogurt or another satisfying snack |
| Sweetened tea | Unsweetened tea with lemon |
These are options, not rules.
If you genuinely want a dessert, enjoying a reasonable portion can be part of a normal eating pattern. The broader goal is to avoid having added sugar dominate your everyday food and drink choices.
Common Mistakes When Trying to Cut Back on Sugar
Trying to Eliminate Everything at Once
A dramatic change may sound motivating, but it can be difficult to maintain.
Focus first on the biggest sources of added sugar in your own routine.
Ignoring Sugary Beverages
Someone might carefully examine cookies and candy while overlooking several sweetened drinks every day.
Because beverages can contain substantial amounts of added sugar, they deserve attention.
Assuming “Natural” Means “Not Added”
Honey, maple syrup, and some other sweeteners can sound healthier because they’re familiar or less processed.
However, when they’re added to food or drinks as sweeteners, the FDA classifies them as added sugars.
Forgetting Serving Sizes
A package may contain multiple servings.
If you eat the entire package, the total amount of added sugar can be several times higher than the amount listed for one serving.
Skipping Meals and Then Chasing Sweets
Severe hunger can make highly palatable foods much harder to ignore.
Regular, satisfying meals can make it easier to respond to hunger rather than waiting until you’re extremely hungry.
Treating One Dessert as a Failure
Eating dessert doesn’t erase everything else you’ve eaten.
One food choice isn’t a complete picture of your health. Look at the pattern over time.
Following Extreme “Sugar Detox” Claims
Your body doesn’t need a dramatic internet “detox” because you ate dessert.
Instead, focus on ordinary nutrition fundamentals: varied foods, adequate nourishment, hydration, regular meals, and reasonable attention to added sugar.
A Practical Sweet Tooth Management Plan
Instead of trying to change everything simultaneously, work through the following sequence.
Identify the Trigger
When a craving appears, ask:
“What was happening right before I wanted something sweet?”
Was it hunger? Boredom? Stress? A particular time of day? A television show? A food advertisement?
Identify the Food
Ask whether you want something sweet in general or one particular food.
That distinction can reveal whether you’re responding to hunger, habit, or a specific cue.
Make One Small Change
Choose one realistic adjustment.
For example:
- Replace one sugary drink with water.
- Add fruit to breakfast.
- Eat a more satisfying afternoon snack.
- Reduce added syrup in coffee.
- Keep sweets away from your immediate study area.
Reassess the Pattern
After several days, notice whether the craving still appears as often.
If it does, look for another trigger. Perhaps the issue isn’t the food itself. It could be hunger, sleep, stress, or routine.
Case Study: When a Nightly Dessert Becomes a Habit
Imagine someone who eats dessert immediately after dinner every night.
At first, the dessert may simply be enjoyable. After months of repetition, however, the brain begins to associate finishing dinner with getting something sweet.
One evening, dinner ends without dessert. The person may still feel that something is missing.
The useful response isn’t necessarily to declare dessert forbidden. Instead, the person could examine the routine.
Possible changes include:
- Waiting several minutes before deciding.
- Having fruit on some evenings.
- Drinking water or another unsweetened beverage.
- Changing the post-dinner activity.
- Keeping dessert as an intentional choice rather than an automatic step.
The important lesson is that habits can be changed by changing the cue-response pattern.
When Sugar Cravings May Need Medical Attention
Most cravings don’t require medical treatment.
However, talk with a trusted adult, doctor, dentist, or registered dietitian if you’re concerned about persistent changes in eating or other symptoms.
Medical advice becomes especially important if sugar cravings occur alongside:
- Unusual or persistent thirst
- Frequent urination
- Significant unexplained changes in weight
- Persistent fatigue
- Repeated episodes of feeling unable to control eating
- Frequent dental problems
- Concerns about blood glucose
- A known history of diabetes or prediabetes
- Significant distress around food or eating
A craving alone doesn’t diagnose diabetes, nutritional deficiency, or any other condition.
If several symptoms occur together, professional evaluation can help determine what’s actually happening.
