Health benefits of quinoa

Quinoa has been given the status of superfood as it is nutrient rich and helps lower the risk of many ailments. Let us look at some of them.

1. Ideal for people allergic to gluten

Quinoa is ideal for people who are allergic to gluten, like those with celiac disease. Not only is it safe for those who need to consume a gluten-free diet, but it also provides them with a lot of nutrients and antioxidants (17).

2. Reduces risk of diabetes

Whole grains like quinoa help reduce the risk of type 2 diabetes, while refined carbs raise this risk. A study was done recently to compare the effects of quinoa and traditional gluten-free products. The study found that quinoa is much better in reducing blood triglycerides and free fatty acids than gluten-free bread or pasta (18).

3. Helps to lose weight

Quinoa is high in protein which helps boost metabolism (19). Its high fibre content makes you feel fuller for longer and helps reduce appetite. The low glycemic index of quinoa has also been linked to the low-calorie intake.

4. Improves heart health

Quinoa is considered good for reducing the risk of heart disease. It contains omega-3 and omega-6 fatty acids and antioxidants which are suitable for heart health.

5. Improves digestion

Quinoa contains insoluble fibre which helps improve the digestive health. It helps in reducing constipation, bloating, flatulence and pain.

Low levels of magnesium are linked to migraines (a magnesium deficiency symptom). Quinoa is a rich source of magnesium, so it helps prevent migraines.

Adverse effects

Quinoa has very few health risks and can be eaten safely by most people. Let us look at some of the harmful effects of quinoa.

1. Lowers absorption of minerals

The presence of phytates in quinoa can reduce the absorption of iron and zinc in the body. Washing or soaking quinoa seeds before cooking them can help reduce the levels of phytates in them.


2. May cause kidney stones

Quinoa contains high amounts of oxalates. Dietary oxalates contribute to the formation of kidney stones as they are associated with low calcium intake (20).
