10. Reduce colon cancer risk

Pistachios may reduce the risk of some cancers, such as colon cancer, due to their high fiber content.

Scientists demonstrated this in 2017 research that showed that roasting the nuts did not affect their health benefits in relation to colon cancer cells.

Learn more about colon cancer in males here.

A 2020 study suggests that they are. Researchers found that a group of people with overweight or obesity who ate a serving of pistachios every day had a lower body mass index and waist circumference than those who did not eat pistachios.

They also found that the group who ate pistachios developed healthy shifts in their food choices, increasing dietary fiber overall and decreasing their high sugar and high fat foods consumption.

However, it is important to note that the researchers believed these results were because pistachio consumption meant increased dietary fiber intake and a decreased consumption of sweets.

Although pistachios are high in fat and calories, the fat they contain is monounsaturated fat. This type of fat can help lower low-density lipoproteins (LDL), or bad cholesterol and reduce the risk of stroke.

The American Heart Association says that the majority of the fats in a person’s diet should be monounsaturated fat to reduce the risk of cardiovascular problems. Eating pistachios in moderation should not affect a person’s weight.

One way to moderate pistachio intake is to buy shelled versions. This can help slow down consumption, allowing the person to realize when they are full and reducing the risk of eating too much.

Learn more about the different types of fat here.

Pistachios are a fiber-rich food source, which means that they help to ease constipation rather than cause it. However, people with nut intolerances or allergies may experience digestive problems, such as diarrhea, gas, bloating, or stomach cramps.

People who suspect they have a nut intolerance should speak to a healthcare professional before introducing nuts to their diet.

Learn more about nut allergies here.
