Did you know? Pistachios are actually fruits. They're actually the seeds of a fruit (the outer fruit is removed during processing). Like other 'nuts', pistachios are a rich source of protein, fibre, vitamin and mineral, which can help people with weight management, protect against diabetes and hypertension and improve digestion. The omega-3 fatty acids present in pistachios can help lower your blood pressure and may also reduce your risk of heart disease.
