Paul Greenberg, a New York City writer and journalist, who has written books about fish before, takes the reader on a journey around much of the world to explore the health benefits of Omega-3 Fatty Acids in The Omega Principle. Greenberg focuses on the subject of Omega-3 Fatty Acids and sees where it takes him. Onto many subjects and places in this trip to validate the enthusiasm the compound brings. Omega-3 Fatty Acids, found in fish but also in some nuts, is trumpeted as a medical remedy and cure helping our hearts and our minds. The enthusiasm over the find rivals that of other miracle drugs, but there are those who doubt whether it is a valid medicine. There are many though who swear by it, and Greenberg follows its use even into ancient times. He is a convert here, and fish consumer and promoter, but also an inquiring mind with great prose and refreshing use of phrases and language. Eating Omega-3 Fatty Acids maybe can be a bit of a cure all for some of our present environmental and public health catastrophe, but fish are also on the decline. A Mediterranean Diet with more fish is recommended by Greenberg who sees it also as a remedy for some of the ails of middle age.
