The first class of foods (meat soups and others) is said to be of high nutritive value conducive for the formation of healthy rasa. The second class of foods (syāmāka and others) is said to be otherwise.

It is known that folic acid supplementation starting before pregnancy can reduce the incidence of neural tube defects. Even deficient maternal vitamin B (12) status has been reported to be associated with a significantly increased risk of neural tube defects. [2] [3] These studies are suggestive of the fact that maternal nutrition plays an important role in embryogenesis. The factor rasa in this context, in fact is indicative of maternal nutrition.

It may be noted that the nuclear genome is characterized by homologous pairs of chromosomes of biparental origin. However, the mitochondrial DNA is transferred exclusively from the mother to the offspring without undergoing any recombination as the paternal mitochondrial DNA undergoes degradation during fertilization. It is interesting to note that the organs afflicted by the diseases transmitted through mitochondrial inheritance are skeletal muscles, brain, heart, eye, colon, pancreas, inner ear, liver, kidney and blood.

The term shukra has been described to be of two forms in Ayurveda textbooks: 1. The one that is ejaculated during the process of mating, which is responsible for fertilization of ovum and thus embryogenesis, and 2. The one that is formed from Majjā (marrow, or the tissue that fills up bone cavities) which in turn circulates all over the body both in males and females.  Reproduction is the function of this second form of shukra also. Therefore, on careful examination, it seems that the first form of shukra stands for semen in general and for sperms in particular and, the second form of shukra stands for hypothalamo-pituitary-gonadal axis of hormones that circulates all over the body. For instance, the GnRH of the hypothalamus stimulates the anterior pituitary to secrete LH which in turn stimulates testes and ovaries to form hormones such as testosterone, estrogen and progesterone. As per Ayurveda classics, the brain, and thus, the hypothalamus, is obviously a part of majjā which is enclosed in mastaka. [5]

The term rasa has been translated by various authors as chyme, chyle, lymph, plasma etc. However, it is difficult to restrict the meaning of this term to any of such specific fluids. As rasa has been described to be a colorless fluid that gets propelled out of the heart by vyāna vāyu into the vascular tree, it is more logical to translate it as plasma. However, the fluids in the interstitial spaces and the fluid in the lymphatic vessels also are to be included under rasa because we find no other apt term that describes these fluids. Moreover, the word rasa includes all those bodily fluids that flow. As the major function of rasa is to nourish the other tissues, we have translated it as nutritive fluid in this context. [6]
