This article is about how we can eat well but still be malnourished.  Here is the article.  Everyone should go check it out.  A lot of these important nutrients are only found in meat, seafood, and dairy products.  The key is that these animals are grass-fed.  It is important that the nutrients from the grass are part of the diet of the animals: cows and chickens (seafood should be wild).  Then the eggs, meat, and dairy are fully packed with with vitamins and nutrients.  Vitamin A only occurs in animal foods.  Babies and growing children right up to age 18 need more vitamin A in their diet as a function of body weight than adults do.  You can give a baby as much or more cod liver oil on a body-weight basis as an adult.  It is fine because they really need that vitamin A.  The books on infant feeding back in the 1930s and 1940s recommended 2 teaspoons of cod liver oil per day for infants over 3 months old.  Vitamin A is an important part of our families diet.  Make sure it is part of yours!
