Rau cần tốt cho người cao huyết ápRau cần được sử dụng khá phổ biến khi nấu canh và các món lẩu nhưng ít ai biết loại rau này còn có giá trị chữa bệnh.
ũng như trong nhiều loại rau quả khác, hàm lượng các chất dinh dưỡng phân bố trong rau cần không đều, thí dụ các chất protit và hợp chất đường (gluxit), caroten, vitamin C có trong lá rau cao hơn hẳn trong thân cây rau.Ngược lại, các chất khoáng như canxi, photpho, sắt... lại tập trung trong thân cây nhiều hơn. Vì vậy, khi chế biến thức ăn, nên chú ý sử dụng cả lá và thân cây rau để không lãng phí chất dinh dưỡng.
