ELI5 - Why I have to eat fruits and vegetables everyday to stay healthy, but an Inuit can go his whole life without ever seeing a vegetable?

From wikipedia: 

>While it is not possible to cultivate plants for food in the Arctic the Inuit have traditionally gathered those that are naturally available. Grasses, tubers, roots, stems, berries, fireweed and seaweed (kuanniq or edible seaweed) were collected and preserved depending on the season and the location.


>Because the fats of the Inuit's wild-caught game are largely monounsaturated and rich in omega-3 fatty acids, the diet does not pose the same health risks as a typical Western high-fat diet.

>Vitamins and minerals which are typically derived from plant sources are nonetheless present in most Inuit diets. Vitamins A and D are present in the oils and livers of cold-water fishes and mammals. Vitamin C is obtained through sources such as caribou liver, kelp, whale skin, and seal brain; because these foods are typically eaten raw or frozen, the vitamin C they contain, which would be destroyed by cooking, is instead preserved.

tl;dr: They do have access to some kind of plants, and many of the vitamins we usually get from plants are also found in the animals that they eat in abundance. In addition, Western diets require more of the nutrients in healthier foods to help the body deal with the higher amount of saturated fat that we eat relative to Inuits.
