Psychoneuroimmunology
There is a mind-body connection that we know as the Autonomic Nervous System (ANS) which when functioning optimally, guides and controls everything happening in the body at all times whether awake or asleep. Stressors that occur in everyday life can negatively affect the mind, body, endocrine function and ultimately the immune system.
Mental stresses can be brought about by poor nutrition, life situations and body malfunction. Body stresses can be induced by poor nutrition, pain, and chronic mental stress. Endocrine function can be reduced by poor nutrition and an ailing autonomic nervous system (back to the mental and body stress). The immune system can ultimately succumb because of poor nutrition, a weak and unbalanced autonomic nervous system and pain.
This field of science was tagged Psychoneuroimmunology roughly 20 years ago but the connections were recognized much earlier by the ancient Greeks. Stress, via bidirectional interactions between the central nervous system, endocrine system, and immune system, impacts the hypothalamic, pituitary, adrenal (HPA) axis, can induce modulation of the immune system and, thereby defense against infectious agents and health.
The diet of human beings prior to the arrival of agriculture, technology and civilization is known as the Paleolithic Diet. In short, it is a diet of the Stone Age which consisted of mainly lean red meat and vegetables. Consumed in large quanties, this type of diet provides 40 to 65% of the energy needed by the body.
Living off of the Paleolithic Diet till the early centuries, people had extremely low rates of cancer, obesity, arthritis, osteoporosis, diabetes and heart diseases before shifting to our modern diets. Therefore, nutritionists and scientists believe that the Paleolithic diet is a great tool for combating modern ailments including obesity, cancer and others.
The foods included in this diet are generally lean red meat, eggs, fish, fruits, nuts and vegetables. Items like breads, pasta, milk, refined sugars were excluded from this diet. This diet used to vary region and culture wise in different countries.
The specialty of this diet is it is rich in protein, fiber, minerals, iron, vitamins, mono unsaturated fat, omega3 fats, antioxidants and phyto-chemicals. On the other hand the diet contains lower quantity of saturated fats, salts, and enzyme inhibitors.
Experts feel that the Paleolithic diet have many health benefits and since foods taken are mostly natural they have no side effects. Since milk and dairy products are excluded in this diet it is safe to have some calcium to protect from rickets, osteoporosis, etc.
