The Most Important Macronutrient for Your Brain is FAT
Sixty percent of your brain is fat. DHA alone makes up about 15 to 20
percent of your brain’s cerebral cortex, as well as 30 to 60 percent
of your retina, making it an essential nutrient for both brain and eye
health. Your neuron membranes are composed of a thin double layer of
fatty acid molecules. Myelin, the protective sheath surrounding your
neurons, is composed of 30 percent protein and 70 percent fat.
You can protect your brain by giving it healthful fats from whole
foods, such as organic eggs from pastured hens, whole raw milk from
pastured cows, raw nuts, avocados, and olive oil. Eggs and dairy are a
rich source of lecithin, choline and vitamin B12 – nutrients
especially important for good brain function. There is also evidence
that coconut oil may offer very significant protection against brain
diseases such as Alzheimer’s, and may even stop brain atrophy in its
tracks.
