Spring Fats/ Fall Fats

This is an extremely good article!

I'll quote part of it here:

"While researching a book on omega-3s, I realized that the essential fats—the omega-3s and their close cousins, the omega-6s—change with the seasons. It might sound like a small idea, but it may soon fundamentally change the way you think about food.
First, let's start with omega-3s, what I'll call the spring fats. These are likely the most abundant fats in the world, but they don't originate in fish, as many believe. Rather, they are found in the green leaves of plants. Fish are full of omega-3s because they eat phytoplankton (the microscopic green plants of the ocean) and seaweed. In plants, these special fatty acids help turn sunlight into sugars, the basis of life on Earth. The spring fats speed up metabolism. They are fats that animals (humans included) use to get ready for times of activity, like the mating season. They're found in the highest concentrations in all the most active tissues: brains, eyes, hearts, the tails of sperm, the flight muscles of hummingbirds. Because fish have so many of these fats in their diets, they can be active in cold, dark waters. These fats protect our brains from neurological disorders and enable our hearts to beat billions of times without incident. But they are vanishing from our diet, and you'll soon understand why.
Next up are the omega-6s, what I'll call the fall fats. They originate in plants as well, but in the seeds of plants rather than the leaves. The fall fats are simply storage fats for plants. Animals require both—omega-3s and omega-6s—in their diets and their tissues. But omega-6s are slower and stiffer than omega-3s. Plus, they promote blood clotting and inflammation, the underlying causes of many diseases, including heart disease and arthritis. Omega-3s, on the other hand, promote blood flow and very little inflammation, which may prevent things like heart disease. The proper mix of these two fats helps create tissue with the right amount of blood flow and inflammation. But because they're in constant competition to enter our cells, if your diet consists of too many omega-6s, your body will be deficient in omega-3s. And that is what's been happening to us as we've been eating more and more seed fats in the form of soybean, corn and other vegetable oils."

Continuing with this line of thought...
The notion of seasonal foods is certainly not new. Cycles and seasons have been celebrated and honored throughout the ages. It is only recently that we have forgotten why. Globalization has made any food available at any time, anywhere on Earth. Our modern heated houses mean our bodies are no longer stressed in the winter cold and so no longer burn winter fat. We have quite effectively removed the seasonal cycles from our lives and our bodies suffer the consequences. Artificial lighting has disrupted day/night cycles creating a sleeping disorder pandemic, lighting also interferes with lunar/menstrual cycles in women, and the seasonal lengthening and shortening of the days is obscured by modern artificial lighting. Chickens will lay eggs all year, cutting their life span in half as a result. In humans, it contributes to the growing (pun intended) obesity pandemic and high blood pressure, heart disease, cancer, diabetes, ...
How much healthier would we be if we simply brought our bodies back into the natural rhythms of nature?
