from my reading i have come to understand that foods with pungent or sharp smell and tastes are to be avoided. not because of sin, but as an aspiring spiritualist, avoiding these foods would help in controling of desire, be it sexual or taste wise. i think it depends of the level of control that the individual has that would determine waether or not they should eat hese foods. as sri ramakrishna says " a young plant must be well guarded, but when fully grown, an elephant can be tied to it " the plant would be your spiritual life and by avioding these things in early spiritual growth, later on when control is there, there is no need to abstain because you now have control over desires
