How well does such low intake of zinc work for most raw vegans though ? We see clearly that such sub-optimal intake of these nutrients doesn't work well for the majority who try these raw vegan diets.

Even on a low phytic acid diet such as the typical raw vegan diet, 4mg of zinc is far, far too low for a male. At the end of the day if 4mg of zinc was enough for most male raw vegans, we wouldn't be seeing the level of copper imbalances and zinc deficiency that we do in the raw vegan movement.

The studies show time and time again that zinc is a common vegan deficiency.

Adam hasn't taken into account the copper/zinc imbalances, that come with eating a strict plant based diet. The typical raw vegan diet contains about 2-3 times the amount of copper to zinc, if not more when you eliminate the only half decent vegan sources of zinc such as beans, pulses, nuts, seeds and even grains to a degree.

This is why we see many raw foodists emaciated despite eating some level of protein, the body requires zinc for protein synthesis. It could be said in theory, that due to the excessive level of copper in a raw vegan diet, that raw vegans may require slightly extra zinc.

Just because you don't have phytic acid binding to a small amount of zinc, doesn't mean you don't have other factors lowering zinc, such as excessive levels of copper, which antagonize zinc, and in extreme circumstances can cause the same symptoms of zinc deficiency. Most raw vegans are very deficient in zinc.

Infact studies are showing that a third of population suffer from sub-optimal zinc levels despite the current RDA. I think the RDA's for alot of nutrients are too low i.e vitamin C, iodine etc. We can probably therapeutically benefit from slightly higher intake of these nutrients.
