Jau, also known as barley, is a cereal grain with a chewy texture and nutty flavor. It's the fourth most important cereal crop in India, after rice, wheat, and maize. Jau is high in fiber, especially beta-glucan, which may help lower cholesterol and blood sugar levels. It's also a good source of selenium, which helps preserve skin elasticity.

Jau is also rich in B-vitamins, which may help lower cholesterol and improve brain health. Research has linked B-vitamins to reducing the risk of cognitive decline due to potential memory boosting benefits. Jau contains phytochemicals, which help with heart health. The presence of copper in barley reduces symptoms of rheumatoid arthritis and maintains flexibility in bones and joints.
