Pistachios 🌰

What It Is?

Pistachios (Pistacia vera) are edible seeds that grow on small trees native to the Middle East and Central Asia. Although commonly referred to as nuts, pistachios are technically seeds. They are known for their green color, slightly sweet flavor, and naturally split shells.

Pistachios provide healthy fats, plant protein, fiber, vitamin B6, potassium, and several antioxidant plant compounds. They are also rich in carotenoids such as lutein and zeaxanthin, which have been studied for their potential roles in eye health and antioxidant protection.

Pistachios are best known for supporting heart health, metabolic health, eye health, weight management, and antioxidant protection.
