Estrogenic substances (that is, stressful substances) are the likely cause, so check out their medications or supplements, but most importantly, they need to eat a diet very low in unsaturated fatty acids and low in meat. A low cholesterol diet might help too, but it's better to simply not cook food that is rich in cholesterol, such as butter, and not worry about cholesterol (because you don't want to ask someone to limit his diet too much, and there seem to be a lot of benefits to food items like butter, so long as you don't cook them). |
