Spinach has always been hailed as a treasure of health benefits in winter season. But daily intake of spinach in excess may prove dangerous to health. Excessive intake of spinach or eating it on a daily basis may cause digestive disorders or health problems in a few people. This article will help you know the health issues caused by spinach.

May Increase the Risk of Kidney Stones

Spinach contains high amounts of oxalate. When oxalate combines with calcium present in the body, it rises to become one of the major causes of kidney stones. Those who have had experiences with the formation of kidney stones should take spinach advisedly.

May Affect the Digestive System

Spinach is rich in fiber, which is generally considered beneficial for digestion. However, consuming too much fiber can cause gas, bloating, or constipation in some people. People with poor digestion should avoid eating large amounts of spinach daily.

Caution Required for Thyroid Patients

There are certain compounds in spinach that can influence the working of the thyroid gland. People who have thyroid ailments must consult their physician before consuming any spinach.

Medications May Decrease Effectiveness

Spinach has high amounts of vitamin K. Such substances can impair blood-thinning drugs. If you take blood-thinning drugs, it is best that you consume spinach in moderation.

Potential for Allergies

In some people, there may be allergy symptoms like itching, swelling, or respiratory problems after consuming spinach. If that happens, it is essential to see a doctor as quickly as possible.

Cause calcium deficiency

The oxalic acid and phytates in spinach may cause inhibition of calcium absorption. Large consumption of spinach may prove to be counterproductive from a bone health standpoint in people already suffering from any bone disorders.

Note for Diabetes Patients: Although spinach is generally considered healthy, diabetics or those taking blood thinners should consume it only as directed by their doctor.
