Nanotech-based Food: An Initiative for Alternative Pharmaceuticals

Nanotechnology opens many avenues in the food sector and offers applications associated with food production, processing, cultivation, and packaging. Nanofood employs nano-techniques like nano-encapsulation to conjugate various phytochemicals, antioxidants, probiotics, minerals, vitamins, etc., into nanovehicles. Food fortification strategies are implemented to incorporate nano-processed substances. Nanofood is mostly used for improving health and as a supplementation in various diseases ranging from liver diseases to neurodegenerative disorders. Here, we focus on recent studies that exhibit comparable results for nanofood and conventional medicines, subsiding the limitations of traditional therapies. Nanofood holds the potential for the management of various health problems and can be used as an alternative to medicine in clinical conditions, like cancers and inflammatory bowel disease. With further advances in nanotechnology and expansion in the scope of the current nanofood industry, in addition to proper regulations set in place, nanofood may offer a wide variety of advantages in terms of safety, long-term stability, etc.
