You should read Real Food: What to Eat and Why by Nina Planck
Here’s an excerpt from a review by Publishers Weekly.
“As Planck reveals, in her compellingly smart Real Food: What to Eat and Why, much of what we have learned about nutrition in the past generation or so is either misinformed or dead wrong, and almost all of the food invented in the last century, and especially since the Second World War, is worse than almost all of the food that we’ve been eating since we developed agriculture. This means, she says, that butter is better than margarine (so, for that matter, is lard); that whole eggs (especially those laid by hens who scratch around in the dirt) are better than egg whites, and that eggs in general are an integral part of a sound diet; that full-fat milk is preferable to skim, raw preferable to pasteurized, au naturel preferable to homogenized.”
Excerpt from a review from Booklist.
“Planck has a lot to offer about the role of fats in a healthy diet. Although most nutritionists worry about people consuming too much fat, Planck distinguishes good fats from bad, noting that many vital nutrients are absorbed into the body only dissolved in fat. She describes the differences between industrial fats that have been chemically saturated and hydrogenated and those fats that occur naturally in vegetables, fish, and meats, especially lauding the benefits of homemade lard. Planck draws a similar line between natural and industrial soy foods. She also encourages people to consume much more seafood, finding the threat of mercury contamination a bit overblown. Above all, Planck links good nutrition to sensible enjoyment of food in all its variety.”
My partner read this book a while back. He was so excited about the information he was learning that he would wake me up just to read me quotes. We have been eliminating processed foods from our diet ever since. We make every meal we eat at home with real ingredients.
