This paper synthesized from literatures and research studies that generated within the context of 'Sustainable Diets' is in an attempt to foster opportunities for healthful practice, choice and life-style behaviour in support of the ecological public health concept associated with connections between disease burden of obesity epidemic and its related rising NCDs under these interwoven relationships of food, health and environmental sustainability concerns. Health professionals should recognize the needs for expanding their professional roles under this paradigm shift by reconceptualizing holistic vision on global health amongst humans, animals and the planetary. Education of this evolving role as integral part of virtuous trends of dietary transition to all disciplines of nutritional health, medicine, nursing and other allied health field are indeed absolutely indispensable for supporting sustainable development in health towards the 21 st century.
