(1) Too Many Antioxidants Are Bad

Vitamin C and other antioxidant compounds such as phytonutrients, etc in turnip protects our cells from free radical damage and reduce the risk of various cancers such as colon cancer, stomach cancer, abdominal cancer, breast cancer, skin cancer, and lung cancer, etc. 

Antioxidants also provide other benefits such as improving cardiovascular health, strengthening immunity, improving respiratory health, promoting detoxification, keeping vital organs like the liver and kidneys healthy, and so on. 

However, an overdose of antioxidants is bad as an excessive amount of antioxidants not only targets the cancer cells but also the healthy cells around them.

As per a study by the National Cancer Institute, smokers who took beta-carotene in large doses were at higher risk of developing lung cancer compared to the other groups.

Overdosing vitamin E for a long time may increase the risk of prostate cancer and hemorrhagic stroke.

Turnips are rich in antioxidants and eating them while being on antioxidants supplementation may cause problems.

Eat turnips in moderation and if you take supplements, ensure that there is no food-drug interference. 


(2) Not So Good For Diabetic Patients

Turnips have a moderate glycemic index of 62. When consumed in moderation, they slow down the rate at which sugar is released into the bloodstream and prevent a sudden spike in blood sugar levels. This helps in managing diabetes.

Dietary fibers in turnips slow down the rate at which sugar is absorbed by the bloodstream and keep blood sugar under control.

Eating turnips while being on a high protein diet further helps in managing diabetes as protein reduces the glycemic properties of turnips.

Despite the advantage, eating turnips in moderation as in excess amount they may drop blood sugar below the healthy range and cause dizziness, excessive hunger, excessive sweating, fast heartbeat, confusion, and moodiness.

If you take diabetes medication, eat turnips after consulting with your doctor to ensure there is no food-drug interference.


(3) May Drop Blood Pressure Levels

Hypertension or high blood pressure is a common health problem that affects millions around the world and is a leading cause of cardiovascular and other health problems.

Turnips contain potassium, a natural vasodilator that relaxes blood vessels improves blood circulation, and provide relief from hypertension or high blood pressure.

Potassium also helps with other functions like maintaining electrolyte balance, improving cardiovascular health, and strengthening bones.

However, overeating turnips may drop our blood pressure below the healthy range and cause dizziness, fainting, nausea, trouble breathing, irregular heartbeat, dehydration, blurred vision, and poor concentration, etc. 

Eating turnips while being on blood pressure medication should be considered only after consulting with a doctor to avoid the risk of interference.

(4) Too Much Dietary Fiber Is Bad For Stomach

Turnips improve digestion as they contain dietary fibers that improve bowel movement, relieve constipation and provide relief from gastrointestinal problems like abdominal pain, gas, bloating, and flatulence, etc.

However, too many dietary fibers may cause poor absorption of nutrients and increase the risk of diarrhea and other digestive problems such as intestinal gas and intestinal blockage, etc.

Also, turnip contains raffinose  ( a non-digestible carbohydrate) that causes gas, bloating, and abdominal pain when consumed in excess.

People with a sensitive digestive system may experience gas and abdominal pain even with a small portion.

To stay safe, eat turnips in moderation. Start with a small portion, and let your digestive system gradually adjust.

Turnips regulate blood sugar levels and reduce the risk of gestational diabetes.

other nutrients like potassium, magnesium, iron, and vitamin B complex, etc also play an important role in maintaining a healthy pregnancy.

However, consuming turnips may cause gas, abdominal pain, and bloating. Individuals with sensitive stomachs are likely to experience these symptoms even with a small portion of turnips.
