9 Side Effects of Eating Too Many Turnips

Turnips are nutritious and tasty root vegetables that have been enjoyed for centuries. From roasted to boiled, turnips are a versatile addition to any meal.

But while turnips can provide essential nutrients and potential health benefits, eating too many can cause some side effects.

This article will explore the possible adverse reactions associated with eating turnips, their nutritional profile, and how to safely enjoy turnips as part of a balanced diet.

What Are Turnips

Turnips are a root vegetable commonly used in dishes around the world. They have white flesh and purple, brown, or red skin. Turnips are low in calories but high in vitamins and minerals including folate, calcium, magnesium, potassium, vitamin C, and dietary fiber. Additionally, they provide small amounts of protein, iron, and zinc.

The nutrition data also shows that turnips contain compounds such as glucosinolates which may provide anti-cancer benefits by inhibiting tumor growth. Furthermore, their high levels of dietary fiber help promote healthy digestion and prevent constipation.

There is evidence to suggest that consuming turnips regularly can reduce cholesterol levels and even improve heart health due to their antioxidant properties. Finally, countless recipes utilize turnips including roasting them with other vegetables or making soups out of them – whatever your preference is!

Nutritional Information

Turnips are nutritious vegetables, providing essential vitamins and minerals.

One cup of cooked turnip contains 34 calories, 0.2 grams of fat, 6.6 grams of carbohydrates, 2.5 grams of dietary fiber, 1 gram of protein, and 3.6 grams of sugar. Additionally, they offer a good source of vitamin C (21% DV), vitamin B6 (10% DV), and potassium (9% DV). They also contain calcium (4% DV), magnesium (3% DV), and folate (3% DV).

The carbohydrate content in turnips is mainly composed of complex carbohydrates – starches that take longer to digest than simple sugars. This helps stabilize blood sugar levels over time which has benefits for weight management as well as energy levels throughout the day.

The high fiber content may help with digestion and keep you feeling fuller for longer periods after eating turnips. Moreover, the low-calorie count makes them an ideal addition to any healthy diet plan when looking to lose or maintain body weight while still getting adequate nutrition from food sources.

Health Benefits

Turnips are a nutritious root vegetable with numerous health benefits. Studies suggest that turnip consumption can reduce the risk of heart disease, lower cholesterol levels and control blood sugar levels. Furthermore, they are beneficial for bone health due to their high calcium content.

Turnip consumption has also been linked to improved digestive health; this is because they contain dietary fiber which aids in digestion while providing bulk to the stool. In addition, turnips possess anti-inflammatory properties, potentially preventing inflammation and helping fight against some cancers.

They may even help boost immunity and improve skin health due to their vitamin C content. All these factors illustrate how turnips provide multiple nutritional benefits when included as part of a healthy diet.

Gas And Bloating

Gas and bloating are common side effects of turnips.

Turnip gas is a frequent complaint amongst individuals who have consumed the vegetable, as it contains raffinose, an indigestible complex carbohydrate that can cause digestive issues when broken down in the intestines by bacteria.

The resulting symptoms include flatulence, abdominal pain, and discomfort. Bloating is another symptom that may be caused by consuming turnips due to their high fiber content. Furthermore, the digestion of turnips can cause excessive production of gas in the stomach and intestines which can lead to further bloating symptoms.

The severity of these digestive complaints varies from person to person; however, if you experience extreme or prolonged flatulence or discomfort after eating turnips then it is advised that you seek medical advice.

It is also important to note that there could be other underlying causes for your digestive discomfort such as food intolerance or allergies.


Diarrhea is a potential side effect of consuming turnips. It can be caused by an intolerance to the vegetable or due to the presence of certain components such as fiber, starches, and other carbohydrates that are difficult for some people to digest.

Symptoms may include frequent loose bowel movements, abdominal cramps, nausea, and dehydration. To prevent or manage diarrhea related to consuming turnips, dietary modifications should be considered. This includes limiting the intake of turnips and avoiding high-fiber foods that may exacerbate symptoms.

Other remedies include drinking plenty of fluids and taking over-the-counter medications such as bismuth subsalicylate which can help reduce symptoms.

If diarrhea persists or worsens despite self-treatment measures, medical attention should be sought to determine if any underlying health issues exist and develop appropriate treatments accordingly.


Turnips contain compounds called goitrogens, which can interfere with the body’s ability to absorb iodine and create hormones needed for proper metabolic control.

Long-term consumption of turnips is linked to an increased risk of thyroid disorders due to decreased production of the hormones thyroxine (T4) and other hormones responsible for the normal functioning of the thyroid gland.

This can lead to various forms of thyroid dysfunction, such as Hashimoto’s disease, which is an autoimmune disorder causing inflammation in the thyroid gland.

Therefore, it is recommended to limit the number of turnips consumed to avoid any future problems related to reduced hormone function caused by decreasing iodine levels in the body.

Allergic Reactions

Turnip allergies are not very common, but they can affect some people.

Symptoms of an allergic reaction to turnips include itching, swelling around the mouth or eyes, stomach aches, diarrhea, and other gastrointestinal issues. If any of these symptoms occur after eating turnips, medical attention should be sought.

Additionally, people who are allergic to other vegetables in the Brassica family, such as cabbage, may also be allergic to turnips.

It is important to get tested if there is a suspicion of an allergy to turnips before consuming them. If a reaction does occur, it is best to avoid eating turnips until further testing is completed to confirm the allergy.

Kidney Problems

Eating turnips regularly has been linked to kidney problems such as kidney stones, cysts, chronic kidney disease (CKD), and glomerulonephritis.

It can also cause inflammation of the kidneys (nephritis) and proteinuria.

To avoid these risks, individuals who eat a lot of turnips should monitor their kidney health and see a doctor if they experience any signs or symptoms of kidney issues, such as pain in the abdomen or back, swelling around the eyes, changes in urination, difficulty breathing, extreme fatigue, nausea, or vomiting.

There is limited information available about the potential side effects of turnips on kidneys, so it is important to seek medical advice if any symptoms of kidney problems occur.

Interference With Medication

Turnips are a nutritious vegetable but can interact negatively with certain medications.

Eating too many turnips can reduce the effectiveness of antibiotics, increase the risk of adverse reactions with blood thinners, and interfere with chemotherapy drugs.

Turnips are high in vitamin K, which can reduce or block the efficacy of drugs used to treat heart conditions, diabetes, and cancer.

People taking medication should be aware of their turnip consumption and should also avoid supplementing their diets with additional dietary fiber, as this could further increase the risk of drug-turnip interactions.

Eating a balanced diet and discussing any potential side effects with a healthcare provider can help to reduce the risk of drug interactions when consuming turnips.

Changes In Urine Color

Turnips are generally considered safe and beneficial to many due to their high nutritional value, consisting of vitamins A & C, folate, and minerals such as phosphorus and magnesium.

However, the yellow-orange pigment present in the vegetable can be passed through excretion and lead to changes in urine color. This is not typically harmful and doesn’t indicate any health issue, but is a sign of recent turnip consumption.

Although not everyone may experience digestive issues as a result of turnip consumption, some may, including allergies, gas, bloating, and diarrhea.

If this occurs, it is recommended to seek professional medical advice. To avoid changes in urine color, it is advised to limit the intake of turnips until further consultation with a healthcare provider.

Gastrointestinal Distress:

Turnips can cause gastrointestinal distress in certain individuals. Symptoms may include turnip gas, diarrhea, stomach pain, bloating, and/or constipation.

Other signs of distress are nausea, indigestion, flatulence, heartburn, cramps, and general discomfort. The severity of these reactions can vary greatly due to factors such as sensitivity, lifestyle habits, and pre-existing medical conditions.

To reduce symptoms, it is advised to eat turnips in moderation and with other foods. Drinking plenty of water can also help improve digestion and prevent dehydration from diarrhea and vomiting.

Interference With Iodine Uptake

Turnips contain goitrogens, which can interfere with the body’s ability to absorb iodine. This can lead to hypothyroidism, as iodine is essential for metabolism, growth, and development.

Eating too many turnips can block the enzymes that help iodine uptake into cells, leading to low thyroid hormone levels. Therefore, it is important to limit turnip intake and be aware of the potential for interference with iodine absorption.

Healthcare professionals should consider this when advising patients with diets high in turnips on how to manage and prevent hypothyroidism.


Turnips are nutritious root vegetables, providing essential vitamins, minerals, and dietary fiber that are beneficial for digestion. However, eating them too often or without consulting a healthcare provider if taking medication can lead to some unwanted side effects.

These may include gas and bloating, diarrhea, urine discoloration, gastrointestinal distress, and reduced iodine uptake, which can interfere with thyroid hormone production.

To ensure these risks are minimized while still benefiting from turnips’ nutritional value, it is recommended that individuals only consume small amounts at one time and consult their healthcare provider before adding them to their diet.
