Introduction
- The term bio-fortification came from Greek word “bios” means “life” and Latin word “fortificare” means “make strong”
- Bio-fortification is the process of fortifying/increasing the nutritional quality of the foods through addition of micro nutrients via agronomic practices, modern biotechnological practices or conventional plant breeding
- It is a feasible and cost-effective method of providing micronutrient rich diet to the families which cannot afford/has no access to balanced diet
- Bio-fortification is similar with fortification in function as both of them increase the nutritional quality of the food. The major difference between them is that bio-fortification focuses on improving the nutritional content of the food during plant growth while fortification is done manually during processing of the crops.
- In case of bio-fortification, instead of adding micronutrients in the harvested food (done in normal fortification), the plants/crops are themselves altered so that they can produce nutrients on their own
- It is a useful method of fortification in contexts where conventional fortification and food supplementation activities cannot be performed effectively
- Some examples of bio-fortification include iron bio-fortification of rice, zinc bio-fortification of wheat, amino acid and protein bio-fortification etc.
- Bio-fortification is also an effective method of reaching to a larger population of poor people who are scattered in different regions and parts of the world
- This method is also considered as a successful food based approach to fulfill the gap of hidden hunger (i.e. micro nutrient deficiency) among the people of lower socio-economic groups. Therefore, also considered as a strategy to combat micronutrient deficiency.
- Bio-fortification is a great example of agriculture, health and nutrition sectors working in a combined way to produce better outcomes
Advantages of bio-fortification
- Bio-fortified crops have higher chances to serve the poor people as bio-fortification is mainly done in staple crops (e.g. wheat, maize, sweet potato etc.) which is a major source of nutrient for the poorer households/families
- It is highly cost effective method as only one time initial investment is needed to develop the fortified seeds/crops which fortify themselves later on. Also, there is no recurrent costs except some costs in maintenance breeding
- It is sustainable method of fortification as fortification passes from on from one generation to next generation of crops without further investment and effort (on bio-fortification)
- Bio-fortified crops have higher yielding along with higher disease resistant and drought tolerance
- This method is far more cheaper compared to addition of nutrients in the processed foods
In order to make the bio-fortification method effective, successful and scalable in all settings, below mentioned issues must be addressed. They are:
- Plant breeders must be able to find a crop with high micro-nutrient content which can be bred into local varieties
- Bioavailability of the crop must be ensured
- Nutritional effectiveness of bio-fortified crops must be established
- Both farmers and food consumers must have full acceptance towards this new food based approach and make it a part of their regular diet
Challenges in bio-fortification:
- Initial cost of research may be higher for developing and under-developed countries
- Difficulty in maintaining regulatory compliance as extremely precautionary regulations must be followed
- Fewer profit margins in the production and distribution of crops make it less attractive for the private sectors. Thus, scarcity of government funds may worsen the scenario for the public
