Potatoes are one of the most widely consumed foods in the world. From crispy French fries to creamy mashed potatoes, they’re a comfort food staple across countless cultures. But while most of us enjoy them cooked, you might wonder: Can you eat raw potatoes?
The short answer is yes, but it’s not recommended. Raw potatoes aren’t toxic in small amounts, but they contain certain compounds and qualities that can make them unpleasant or even harmful if eaten in large quantities.
In this guide, we’ll dive deep into everything you need to know about eating raw potatoes — their nutrition, possible health risks, potential benefits, and safer alternatives. By the end, you’ll have a clear understanding of whether that crunchy raw potato bite is worth it.
What Are Potatoes?
Potatoes are starchy root vegetables that belong to the nightshade family (Solanaceae), the same family as tomatoes, peppers, and eggplants. Native to South America, they have been cultivated for over 7,000 years and spread globally after the 16th century.
Potatoes are incredibly versatile and nutritious when cooked, providing carbohydrates, vitamins, minerals, and antioxidants. However, like many plants in the nightshade family, they also contain natural defense chemicals that can be problematic when consumed raw.
Nutritional Profile of Potatoes (Per 100g, Raw)

As you can see, raw potatoes are packed with vitamins and minerals, especially Vitamin C and potassium. However, the nutritional benefits don’t necessarily outweigh the risks when eaten raw.
What Happens If You Eat Raw Potatoes?
When you eat a raw potato, several things happen in your body:
- Starchy Texture – Raw potatoes are firm, chalky, and starchy. Unlike the fluffy, soft texture when cooked, the starch granules in raw potatoes are resistant to digestion. This makes them harder to chew and digest.
- Resistant Starch – Raw potatoes contain resistant starch, a type of carbohydrate that your body cannot fully digest. While resistant starch has some gut health benefits, eating too much raw potato may cause bloating, gas, or discomfort.
- Antinutrients – Raw potatoes contain compounds such as lectins and protease inhibitors, which can interfere with digestion and nutrient absorption. Cooking helps deactivate these compounds.
- Toxic Compounds (Solanine & Chaconine) – The most concerning aspect of eating raw potatoes is the presence of glycoalkaloids like solanine and chaconine. In large amounts, these compounds can cause nausea, headaches, vomiting, and even neurological symptoms.
- Bitter Taste – Raw potatoes often taste bitter or unpleasant, especially if they’ve been exposed to light and developed green spots (a sign of solanine buildup).
Risks of Eating Raw Potatoes
Let’s break down the main concerns in more detail.
1. Solanine and Chaconine Toxicity
Potatoes naturally produce glycoalkaloids like solanine and chaconine as a defense against pests and fungi. While small amounts are usually harmless, eating too much raw potato — especially those that have turned green or sprouted — can cause symptoms of poisoning:
- Nausea
- Vomiting
- Diarrhea
- Headaches
- Dizziness
- Abdominal pain
Severe cases are rare but possible, especially in children.
2. Digestive Discomfort
Raw potato starch resists digestion in the small intestine. While some resistant starch is beneficial for gut bacteria, too much can lead to:
- Bloating
- Gas
- Cramps
- Discomfort
Cooking potatoes turns resistant starch into digestible starch, making them much gentler on your digestive system.
3. Interference with Nutrient Absorption
Raw potatoes contain antinutrients like lectins, which can interfere with nutrient absorption and damage gut cells if consumed in large amounts. Cooking reduces these antinutrients significantly.
4. Risk of Foodborne Illness
Eating raw potatoes that are unwashed increases the risk of ingesting bacteria or pesticides from the soil. Cooking typically eliminates these risks.
Are There Any Benefits of Eating Raw Potatoes?
Despite the risks, some proponents claim benefits to consuming raw potatoes in moderation. Let’s explore them.
1. Resistant Starch for Gut Health
Resistant starch can act as a prebiotic, feeding healthy gut bacteria and improving digestive health. However, you don’t need raw potatoes to get resistant starch — cooled cooked potatoes also contain it.
2. Vitamin C Preservation
Cooking reduces Vitamin C levels in potatoes. Eating them raw may preserve this nutrient better, as Vitamin C is heat-sensitive.
3. Folk Remedies
Some traditional remedies suggest raw potato juice for soothing gastritis or applying raw potato slices for skin burns and inflammation. While there’s anecdotal support, scientific evidence is limited.
Do People Eat Raw Potatoes Anywhere?
Raw potatoes aren’t commonly eaten as a snack or meal in most cultures. However:
- In some European countries, potato juice is used in natural medicine for digestive issues.
- In certain raw food diets, small amounts of raw potato may be included for resistant starch benefits.
- Potato slices are sometimes eaten raw with vinegar or salt in folk traditions, but this is rare.
How to Minimize Risks If You Do Eat Raw Potatoes?
If you’re curious and want to try raw potato, here are some safety tips:
- Choose Young, Fresh Potatoes – New potatoes are lower in glycoalkaloids than mature ones.
- Avoid Green or Sprouted Potatoes – Green patches signal high solanine content.
- Peel the Skin – Most glycoalkaloids are concentrated in the skin and just beneath it.
- Wash Thoroughly – To remove dirt, bacteria, and pesticide residues.
- Eat Small Quantities – Limit intake to avoid digestive upset.
Best (and Safer) Ways to Eat Potatoes
If you want the nutrition without the risks, cooking is the best choice. Cooking methods affect potato health benefits differently:
- Boiling – Reduces glycoalkaloids and makes potatoes soft and digestible but may reduce Vitamin C.
- Steaming – Preserves more nutrients than boiling.
- Baking/Roasting – Brings out natural sweetness but may increase calorie density.
- Cooling After Cooking – Increases resistant starch, giving you gut health benefits without the raw risks.
Myths and Misconceptions About Eating Raw Potatoes
- “Raw potatoes are deadly.” – Not true in small amounts, but they can cause discomfort or mild toxicity if eaten excessively.
- “Raw potato juice cures stomach ulcers.” – There’s limited evidence. Some studies suggest potential soothing effects, but it’s not a proven treatment.
- “Green potatoes are safe if you cut off the green parts.” – False. Even beneath the green surface, solanine levels may remain high.
Who Should Absolutely Avoid Eating Raw Potatoes?
Some groups should be particularly cautious:
- Children – More sensitive to glycoalkaloid toxicity.
- Pregnant Women – Risk of digestive upset or potential toxin effects.
- People with Digestive Issues – Those prone to bloating, IBS, or weak digestion should avoid raw starches.
- Individuals with Compromised Immunity – Higher risk from bacteria or pathogens on raw produce.
FAQ’s
Are raw potatoes toxic?
Raw potatoes contain glycoalkaloids (solanine and chaconine), which can be toxic in large amounts, especially if the potato is green or sprouted.
Can raw potatoes kill you?
It’s extremely rare. You would need to eat a large quantity of raw green potatoes for solanine levels to become life-threatening.
Can you eat raw potato skins?
No, raw potato skins have higher concentrations of toxins. Cooked potato skins are safe and nutritious, but raw ones should be avoided.
Are sweet potatoes safe to eat raw?
Yes, raw sweet potatoes do not contain harmful glycoalkaloids and are often used in salads or smoothies.
Why do raw potatoes taste bitter?
The bitter taste usually comes from glycoalkaloids like solanine, which increase when potatoes are exposed to light and turn green.
Can children eat raw potatoes?
Children should avoid raw potatoes because they are more sensitive to solanine and digestive discomfort.
What is the best way to eat potatoes safely?
Cooking potatoes by boiling, baking, or steaming reduces toxins, improves digestibility, and makes them safe and nutritious to eat.
Is it OK to eat a small piece of raw potato?
Yes, a small bite is unlikely to cause harm, but it’s not a good habit due to digestive issues and toxin risks.
Do raw potatoes taste good?
Most people find them chalky, bitter, and unpleasant compared to cooked potatoes.
Final Thoughts: Should You Eat Raw Potatoes?
While you technically can eat raw potatoes, it’s not advisable. Raw potatoes carry risks of digestive upset, nutrient interference, and exposure to natural toxins like solanine. The potential benefits — such as resistant starch and Vitamin C preservation — are better obtained through safer sources.
If you’re looking for ways to boost gut health or nutrient intake, cooked and cooled potatoes, raw sweet potatoes, or other resistant starch-rich foods like green bananas are better options. So the next time you’re peeling potatoes for dinner and feel tempted to snack on a slice, remember: it’s safer, tastier, and healthier to enjoy potatoes cooked.
