Food Fortification and Nutraceuticals

Food Fortification

Food fortification is the deliberate addition of one or more essential micronutrients to commonly consumed foods to increase their nutritional value and address nutrient deficiencies in a population. It is considered one of the most cost-effective public health strategies for combating hidden hunger (micronutrient malnutrition).

Types of Fortification

1. Mass fortification — addition of nutrients to staple foods consumed by the general population (e.g., iodized salt, fortified wheat flour)
2. Targeted fortification — fortification of foods consumed by specific at-risk groups (e.g., complementary foods for infants)
3. Market-driven fortification — voluntary fortification by food manufacturers to add value to commercial products

Major Fortification Programs in India

Food Vehicle	Nutrient Added	Deficiency Addressed
Salt	Iodine	Iodine Deficiency Disorders (IDD)
Wheat flour (atta)	Iron, folic acid, vitamin B12	Anemia
Rice	Iron, folic acid, vitamin B12	Anemia
Edible oil	Vitamin A, vitamin D	Vitamin A deficiency, rickets
Milk	Vitamin A, vitamin D	Micronutrient deficiency
Double-fortified salt	Iodine + iron	IDD and anemia

FSSAI's +F logo (the fortification logo) is used to identify fortified food products. The Food Safety and Standards (Fortification of Foods) Regulations, 2018 specify the standards for fortification of staple foods in India.

Biofortification

Biofortification is the process of increasing the nutritional quality of food crops through conventional plant breeding, agronomic practices, or genetic engineering. Unlike industrial fortification, biofortification improves the nutrient content of the crop itself.

Examples:

• Iron-rich pearl millet — developed by ICRISAT
• Zinc-rich wheat — varieties released by ICAR
• Provitamin A orange-fleshed sweet potato — rich in beta-carotene
• Golden Rice — genetically engineered to produce beta-carotene
• Iron and zinc biofortified lentils — developed through HarvestPlus program

Functional Foods and Nutraceuticals

Functional foods are foods that provide health benefits beyond basic nutrition when consumed as part of a regular diet. They contain bioactive compounds that may reduce disease risk.

Examples include probiotic yogurt (gut health), omega-3 enriched eggs, beta-glucan-rich oats (cholesterol reduction), lycopene-rich tomatoes (antioxidant), and turmeric (curcumin — anti-inflammatory).

Nutraceuticals are products derived from food sources that provide health benefits in addition to their nutritional value. The term combines "nutrition" and "pharmaceutical." They are available in concentrated forms such as capsules, tablets, and powders.

Categories include dietary supplements (vitamins, minerals, herbal extracts), prebiotics and probiotics, phytochemicals (flavonoids, carotenoids, polyphenols), and omega-3 fatty acid supplements.

The global nutraceutical market is growing rapidly, with India emerging as a significant player due to its rich biodiversity and traditional knowledge of medicinal plants (Ayurveda, Unani). FSSAI regulates nutraceuticals under the Food Safety and Standards (Health Supplements, Nutraceuticals, Food for Special Dietary Use, Food for Special Medical Purpose, Functional Food and Novel Food) Regulations.
