Most seeds are nutritious and many are used in cooking. Two in particular – sunflower seeds and pumpkin seeds – offer valuable benefits. Packed with vitamin E, sunflower seeds also supply folate, a possible cancer-fighter. Pumpkin seeds are rich in zinc, an immune-system booster.
As well as being used in the production of polyunsaturated oil and margarine, sunflower seeds are also roasted and ground to make a flour, which is available from health food shops.
