I am new to the list but have been a paleo-eater for about a year and a half, with good success, although, like many others, I find that it becomes expensive! I have a few questions, so that's why I'm joining the list. I have two questions regarding an article I recently read dealing with PMS & nutrition, which recommeded reducing salt, sugar, & animal fat, and increasing B6, magnesium, fiber, and other fats to alleviate premenstrual symptoms. The author indicated that PMS headaches, dizziness, & fatigue are blood-sugar related, and anxiety, moodiness and depression are related to surplus estrogen. I was especially interested in what he had to say about 1) magnesium and 2) animal fat. With regard to magnesium, he mentioned that the RDA is too low, that magnesium consumption in the US has drastically dropped in the past 35 years (why?), and that magnesium consumption by women with PMS symptoms should be close to 1000mg. I have read in other sources that magnesium deficiency is also a common cause/factor for post partum depression. What are natural (food) sources of this mineral? Should I consider a supplement, or does a paleodiet naturally supply a higher level of magnesium? What foods should I increase/ adjust? With regard to his comment on animal fat, he says that excess animal fat elevates estrogen levels, causing symptoms. I wondered if this is not so much an issue of animal fat as imbalance of omega-3 to -6? Because evening primrose oil and other omega-3 supplements are known to be helpful with female hormonal problems. Does anyone have any info about this? thanks, Mary
