SRdude, please save your rant for some other place. This thread is not called the great health debate, so please stay on topic. Participants on this forum can generally distinguish a response that is reasoned, thoughtful, and well put together, from one that lacks those qualities.
Magic7, why I can recommend, staying away from animal products and refined foods for your condition without any qualifications, is because in simple terms, the higher your diet is in these foods, the more likely you are to develope heart disease, cirulatory disorders, type two diabetes, and after age 60 the spectrum of cognitive decline and dementias. These conditions do cause erectile dysfunction, so it behooves all of us to do all we can to avoid them.
SR dude is correct that packaged foods, are high in refined sugars, which I cautioned against. They also contain additives, which you want to avoid since they can build up in your sysetm (but which may not play a role in your specific problem.) They also contain massive amounts of sodium, which can raise blood pressure in certain individuals. High blood pressure sometimes spells low erection quality believe it or not.
As to the relative merits of animal products in the diet, this is largely a hypothetical debate. If you could eat fresh organic eggs from your own well cared for pet chickens, and fresh raw organic milk from your own well cared for pet cow, that might work in moderation. And of course, it would have to be in moderation as it very much was in the past, since these animals take up a great deal of the resources, food, water, money, space, waste treatment, that you would otherwise allocate to yourself. But this is all irrelevant, since this is no longer how animals are raised. Animal foods today are industrial products as much as any processed food is, and impact health negatively. A sound reccomendation for any individual is to limit or reduce their consumption.
Eggs and dairy products contain less saturated fat than meat, and that fat itself is less saturated. They also contain fewer Advanced-glycation end products, heterocyclic aromatic amines (potent carcinigens caused by cooking meat) and heme iron when cooked than meat does. So, these are preferable to meat, for your condition, and organic is even better. Milk and dairy products today though are ultra-pasturized (heated to intense temperatures) and homogenized (extruded through something like a mist nozzle, in order to reduce the fat globules to sizes small enough to remain in suspension.) The problem is that in modern industrial milk, both organic and not, these proceses alter the composition of the dairy fat, make this fat more readily oxidized, and are implicated in coronary artery disease and suspected in diabetes. Non-organic agriculture cows are also treated with antibiotics and hormones, which of course pass to those who consume their milk (or bodies). These are far more potent and dangerous than the soy products that SRdude decries. Additionally, while the milk of grass fed cows are full of saturated fats (bad for cirulation, and erectile function) they also contain positive fats, such as Conjugated linoleic acid, and even DHA (Omega 3s). Traditional dairy in moderation has its good and bad points. Keep in mind though that even organic raised cows are not raised traditionally or allowed to eat grass. They eat mostly organic grain - which SRdude again decries. This is not their natural food and causes a variety of problems for them and us. SrDude points out that eggs are the best animal food, and they just may be. Choose organic, cage free, and omega three enriched. These should cost you about $4 a dozen, which if for no other reason will encourage you to eat them in moderation. Remember though one large egg a day is better for you (and provides more and better-absorbed protein) than one small steak a week.
As to soy, keep it in moderation, and keep it to traditional soy foods. Choose organic soymilk, tofu, tempeh, and yuba - the soy foods eaten in Asia for thousands of years. These are processed the traditional way (boiling, curdling, fermenting), which breaks down the anutrients that can lead to nutritional deficiencies. Societies have known how do do this with their staple crops, or there would not be societies. But soy is neither a panacea nor a danger-food. Corn, likewise, if eaten as a staple, but which has not undergone nixtamalization (treatment with lye) causes pellagra. It is how you eat it, how much, and what else you eat. No one suggested you become a veggie-burger-vegetarian. Keep processed soy products (boca, gardein, morning star, TVP) and fake meats as a few-times-a-week treat. Know though that they would still be better for you if substituted one-for-one in place of meat, even if you were to eat them several times a day.
A pair of great, informative books on all things nutrition are "What to Eat" and "Food Politics" by Marion Nestle.
Amazon.com: What to Eat (9780865477384): Marion Nestle: Books
Amazon.com: Food Politics: How the Food Industry Influences Nutrition, and Health, Revised and Expanded Edition (California Studies in Food and Culture) (9780520254039): Marion Nestle: Books
Marion Nestle is Paulette Goddard Professor in the Department of Nutrition, Food Studies, and Public Health at New York University and was involed in the developement of the Food Pyramid. Her work is no-nonsense, scientific, and an excellent primer for the layman interested in food and health. I highly reccomend it.
But, don't get discouraged. You don't need a PHD to take good care of your body. I gave you my reccomendations Magic7, because they are safe and effective for just about everyone. I hope this helps!
