This Guide provides guidance, on how cooking demonstrations can be implemented most effectively so that optimal impact on improved nutrition is achieved, especially for women of reproductive age and children aged 6-23 months. Optimal complementary feeding of the children helps to ensure proper infant growth and development and prevent malnutrition. Inappropriate complementary feeding practices and a low dietary diversity can contribute to malnutrition. Supporting mothers and caregivers with knowledge and skills in preparing nutritious foods for children and all family members is important. One approach that is used to provide mothers and caregivers with the required skills and knowledge to prepare nutritious foods are cooking demonstrations. In general, the diets of most households in Zambia were found to be monotonous (Alamu et al., 2019). High levels of food insecurity, low levels of knowledge about adequate nutrition especially for women of reproductive age and young children, and low crop diversity have contributed to the low dietary diversity. Crop diversification can result in a diverse diet in a household. Diversified diets provide different nutrients required by the body. Women of reproductive age and young children require an adequate and diverse diet for a healthy life and optimal development. Nutritionally adequate and safe complementary foods for children aged 6-23 months have been a challenge when the diets are not diversified. In addition, meal frequency in these children has not been adequate.
