The “health” culture has it all backwards
Thyroid suppressive diets. Restricting salt, dairy, animal protein. Eating nuts, seeds, uncooked vegetables, legumes. Polyunsaturated fats that all lower thyroid function. They also damage mitochondria and delicate enzymes through lipid peroxidation.
Decreased thyroid hormone and progesterone, increased estrogen and stress hormones.
Being in a chronically high catabolic stressed state: breakdown of tissue like skin, muscle and bone loss
“All phases of development, from gestation to aging, are altered by the presence of the unsaturated fats, and these effects correspond closely to the loss of regenerative capacity, the ability to replenish and restore tissues.”
