POTENTIAL CONTRIBUTION OF KENYAN-GROWN QUINOA IN IMPROVING MACRONUTRIENT AND MICRONUTRIENT INTAKE IN CHILDREN AGED 2-6 YEARS IN KENYA

The triple burden of malnutrition is a problem that is being fought against at global, continental, regional and national levels. When consumed in adequate quantities, healthy diets are important in reversing the menace of malnutrition. In Kenya, grains are an important source of energy and micronutrients. Even though they contribute most energy and micronutrients, a huge Recommended Daily Allowance deficit still exists. Incorporating ancient grains such as quinoa which are nutrient-rich and can survive in harsh climatic zones into the diets, can boost the efforts made towards the fight against malnutrition. Though quinoa adaptation trials have been conducted in Kenya, expanded data on the nutrient content are yet to be compiled. Between May 2022 and August 2022, four varieties of quinoa; Cherry Vanilla, Titicaca, Brilliant Bright Red and Biobio were grown at the University of Nairobi, Upper Kabete campus field station. The harvests of the four varieties were separately analyzed to determine and compare the content levels of macronutrients (carbohydrates, crude protein, fats) and micro-nutrients (manganese, magnesium, potassium, calcium, iron, copper and zinc). The four varieties were significantly different in all the analyzed elements except moisture content. Cherry vanilla had the highest level of crude protein (25.1[+ or -]0.3g/100g) and fat (11.46[+ or -]0.184g/100g) but the lowest level of carbohydrates (42.5[+ or -]0.4%). Titicaca had the highest amounts of; manganese (21.9[+ or -]0.06g/100g), potassium (511.9[+ or -]0.03mg/100g), iron (11.5[+ or -] 0.07mg/100g) and zinc (14.1[+ or -]0.0mg/100g). Biobio variety exhibited the highest amount of magnesium (73.9[+ or -]0.1mg/100g). In conclusion, the different varieties of quinoa significantly differ in their levels of macro and micronutrients. The Kenyan-grown quinoa has the potential to contribute to increased dietary intake of both macronutrients and micronutrients of children aged 2-6 years old. The Kenyan-grown quinoa contains levels of micronutrients in higher amounts compared to maize, rice and wheat - the commonly consumed cereals in Kenya. On this basis, the study recommends that the growing and consumption of quinoa should be promoted in Kenya and introduced into the diets of children aged 2-6 years of age in Kenya. Quinoa-based products for children aged 2-6 years should be developed. Climate zone-oriented agronomic trials on quinoa farming should be conducted.
