The answer is simple: eat fish (preferably oily fish) at least twice a week. Although we can certainly tell you which fish oil supplements (or other omega-3 supplements) are best for providing EPA and/or DHA, our analyses of the clinical literature show that, for both age-related macular degeneration (AMD) and Alzheimer's disease, supplements have generally not been beneficial, while regular consumption of fish is associated with benefits. Only if you won't or can't eat fish at least twice a week might fish oil supplements be helpful for these conditions. 

For more details, see the Alzheimer's Disease and Eye Disease sections of the Fish Oil and Omega-3 Supplements Review.

Your statement that "fish is not beneficial for human consumption for any reason" is not correct, nor does the website you mention seem to make that blanket statement. There are benefits and risks with consuming any food. With fish, the benefits come from essential nutrients, like protein, good fats, and vitamins A and D (particularly from fish liver). The risks are from contaminants, such a mercury and PCBs, as well as from excess consumption. Eating fish can be quite healthful, but you need to avoid or minimize contaminants and, as with anything, don't overdo it. For more details, see our review of canned fish products (, fish oils (, and vitamin A/cod liver oil (, in which we have tested products on the market and provide clinical information about use and side effects.
