如今,美食家们对吃提出了更高的要求。他们不仅要观色、闻香、尝味、赏形,而且还要求食物具有养生方面的特色。
This is from the Standard Course Book of HSK5, section 19. I don't understand the meaning of 方面的特色。Actually, I cannot make the need of both words make sense:
而且(furthermore)还(also)要求(they require)食物(the food)具有(to have)养生(health-preserving)的方面(aspects)
而且(furthermore)还(also)要求(they require)食物(the food)具有(to have)养生(health-preserving)的特色(characteristics)
So why are both needed? Or how to make the 方面的特色 = aspect characteristic make sense?
