10 Side Effects Of Asparagus

Read on to know about the various side effects of eating asparagus and the right way to use it to avoid the negative effects.

1. Might Experience A Dry Mouth

Asparagus stems are powerful natural diuretic veggies. This diuretic nature triggers frequent urination, leading to dehydration. The lesser the fluid levels are in your body, the more the dehydration levels will be. This, in turn, will leave you dry mouthed.

2. Bowel Mobility May Suffer A Setback

This springtime bright green veggie stalks are potential treasure troves of fiber. 100 grams of this veggies contain 2.1% of fiber, meeting up to 8% of the recommended daily value of the nutrient. Excessive intake of fiber is not advisable. The fiber eliminates the moisture, thus hardening the stools. Thus, in turn, affects the bowel movement in the small intestine negatively. The result – you might experience an obstruction in the intestine, accompanied by constipation, cramps, and pain.

3. Foul Smelling Urine

This is one of the most commonly reported side effects of eating asparagus. This vegetable contains aspargusic acid, a compound that breaks down into sulfur compounds, which make your urine smell foul (5). However, keep in mind that the smell can vary depending on the genes, i.e., some genetic variants may not experience smelly urine.

4. Not Safe For People Having Edema Conditions

6. May Cause Flatulence

Foods rich in carbohydrates, especially dietary fiber, causes gas in the digestive tract. While studies suggest that people, on a daily average, pass gas 14 times. Asparagus is the trove of raffinose, the complex carbohydrate that contains 3 different sugar variants – glucose, fructose, and galactose. We do not possess the enzyme essential for breaking down this carbohydrate and hence, it gets fermented by bacteria, triggering the formation of gas in excess. Excessive gas puts you under the siege of burp as well as flatulence. Just make sure you do not overindulge in this healthy delight!

Asparagus also contains fructan, a carbohydrate, which may be difficult to digest and cause intolerance. The typical symptoms of fructan intolerance are gas, bloating, belching, distension, and constipation or diarrhea (7).

Asparagus is known to have a positive role in regulating the blood pressure level, thus alleviating the risks associated with hypertension.
