Since wine is natural and made from fruit, I would say it is OK in moderation. Obviously we know the polyphenols in red wine has high antioxidant properties, anticancer, etc. so I say drink it IN MODERATION. Now a bottle per night, that is too much. There is a high probability that wine and other fermented products were used by our ancestors thousands of years ago. Off hand I cannot provide you with the research for it although I am sure it is a mouse click away.
Fasting, there is too much to explain about it as far as insulin sensitivity and how our ancestors fasted during long days and nights of hunting. Again, all this info is a mouse click away. Check out Robb Wolf. He is the go-to go on the paleo lifestyle along with Loren Cordain of course.
Vitamin D, the mother of all vitamins. In fact, latest research shows it is actually considered a hormone. Name a disease-it is linked to low levels of vitamin D. Cancer rates are associated with low D. Elite athletes that supplement with D, as compared to those who dont, have better balance, better coordination, more strength, more endurance, etc. Even the common cold anf the flu are linked to low D. This is one supplement that everyone needs to be on. You can get it from fatty fish ( salmon, tuna, mackerel, sardines), eggs and cod liver oil. It is also synthesized in the stratum basale and stratum spinosum layers of the skin. So all this jargon about avoiding the sun is a crock! Unless you are pale as can be, have freckles and are a red head.
The RDA of Vit D is 400IU. That is the bare minimum to prevent rickets. I recommend supplementing 1000-2000IU/day. Take the D with fat containg foods as it is fat soluble-nuts, avocados, olive oil, coconut oil, fish. Not all supplements are created equal. You want to purchase a company that is third party regulated. i.e. dont purchase from a GNC , walmart , target etc. Garden of life is a great whole food organic product regulated by a third party.
