Pistachios are packed with essential vitamins, minerals, and antioxidants which provide numerous health benefits. In fact, the high fiber nutrient of pistachios helps to relieve constipation in normal circumstances.

However, in some cases, pistachios can promote constipation. This article will cover the constipating factors of pistachios along with pistachios’ benefits for constipated patients.

Can Pistachios Cause Constipation?

Fiber-rich pistachios do not cause constipation in healthy adults. Studies have shown that fiber can increase the frequency, of stools and softens it (1). That’s why pistachios can help to aid in smooth bowel movements.

Moreover, pistachios are a rich source of magnesium also. Magnesium is an essential micronutrient, a deficiency that leads to constipation (2). As pistachios contain a high amount of magnesium, intake of pistachios can help to prevent constipation.

Furthermore, pistachios contain very little amount of saturated fat. Saturated fat is a well-known constipation factor. In fact, more than 30 grams of saturated fat consumption per day is associated with constipation (3).

On the other hand, 100 grams of pistachios contain only 5.91 grams of saturated fat (4). This little amount of saturated fat does not promote constipation in normal circumstances.

When Do Pistachios Cause Constipation?

Although, pistachios are good for constipation, in certain circumstances pistachios can cause constipation. The first and foremost reason for pistachios constipation is not drinking adequate water after consumption of high fiber pistachios.

Dietary fibers from foods are not digestible. Only a very little portion of the fiber is absorbed in the stomach and intestine. The remaining portion of the fiber is passed via stool. Consumption of high fiber can cause phytobezoar formation in the gastrointestinal tract.

The accumulated phytobezoar from the fiber is associated with small bowel obstruction (5). Which in turn promotes constipation. Moreover, several people who are intolerant to nuts, seeds, or pistachios can get affected with gut problems like constipation.

Pistachios have an allergic properties and several people are allergic to them. On the other hand, constipation is one of the most common symptoms of food allergic reactions (6).

Moreover, pistachios contain a high amount of a chemical compound called Salicylates. Studies have shown that dietary intake of salicylates can affect functional gastrointestinal symptoms in patients with IBS (7). This in turn can cause constipation.

Does Eating Too Many Pistachios Cause Constipation In Healthy Adults?

Too much consumption of pistachios may cause constipation in healthy adults because it overloads fiber and saturated fat in the human body. As high consumption of both dietary fiber and saturated fats are interconnected to constipation, too many pistachios promote constipation.

In fact, one cup of pistachios(123 grams)  contains 13 grams of dietary fiber and 7.27 grams of saturated fats. On the other hand, The American Dietary Guidelines have a recommendation of  28 grams of fiber against 2000 calorie intake (8).

That’s why more than four cups of pistachios intake can cross the recommended fiber level which in turn can promote constipation through phytobezoar formation in the gastrointestinal tract.

On the other hand, the same intake level is near about 29 grams of saturated fat. As more than 30 grams of saturated fat is associated with constipation you may get constipated upon consuming too many pistachios.

Also, another study has shown that a diet rich in saturated fatty acids (SFAs) enhances intestinal permeability (9). Intestinal blockage is a common side-effect of intestinal permeability. This intestinal blockage can trigger constipation also.
