(John Reginald Nuttall); Emmambux, Mohammad Naushad; Kruger, Johanita (Wiley, 2015-01)One cause of obesity and related diseases like type-2 diabetes is overconsumption of cereal foods with readily available carbohydrates, resulting in hyperglycaemia and ultimately insulin resistance. A strategy to combat ...

Krishnamoorthy, Srinivasan; Coetzee, Vinet; Kruger, Johanita; Potgieter, Hanneke; Buys, E.M. (Elna Maria) (Elsevier, 2020-03)OBJECTIVE : To determine the association between the fecal microbiota diversity of the infants with different disease conditions, and vitamin A supplementation, antibiotic, and deworming therapies. STUDY DESIGN : In this ...

Kruger, Johanita; Oelofse, Andre; Taylor, J.R.N. (John Reginald Nuttall) (Informa Healthcare, 2014-08)Soaking of cereal grains has been suggested as a method to reduce their phytate content and hence increase their mineral availability. Whole and milled wholegrain, normal and low phytate sorghum and normal maize were ...
-
Adeyanju, Adeyemi A.; Kruger, Johanita; Taylor, J.R.N. (John Reginald Nuttall); Duodu, Kwaku Gyebi (Wiley, 2019-03)Souring by lactic acid fermentation and lactic acid acidification as well as inclusion of amaranth were explored as ways of improving the protein quality and iron and zinc bioaccessibilities of non‐alcoholic sorghum‐based ...
-
Vilakati, Nokuthula; Taylor, J.R.N. (John Reginald Nuttall); MacIntyre, Una Elizabeth; Kruger, Johanita (Elsevier, 2016-11)While dietary diversification of monotonous cereal-based diets using legumes and vegetables can alleviate the high prevalence of iron and zinc deficiencies in sub-Saharan African children, laborious cooking times limit ...
-
Kruger, Johanita; Taylor, J.R.N. (John Reginald Nuttall); Oelofse, Andre (Elsevier, 2012-03)Improved iron availability from sorghum porridges will benefit many malnourished communities in rural Africa, where there is a high prevalence of iron deficiency. This research compared the efficacy of reducing sorghum ...
-
Kruger, Johanita (AgriConnect, 2016-08)While milk has long been regarded as a healthy, whole food that can provide almost all the nutrition one needs, the Internet and social media are full of negative information about milk, especially as far as its role ...

Van der Merwe, Renee; Kruger, Johanita; Ferruzzi, Mario G.; Duodu, Kwaku Gyebi; Taylor, J.R.N. (John Reginald Nuttall) (Springer, 2019-03)Essential mineral (iron and zinc) deficiencies are still prevalent in the Semi-arid Tropics, where many people consume monotonous, predominantly cereal-based diets. This study aimed to evaluate the potential of including ...
-
Gwamba, John; Kruger, Johanita; Taylor, J.R.N. (John Reginald Nuttall) (Wiley, 2020-04)The present study aimed at determining whether mineral biofortified pearl millets will continue to maintain significantly higher iron and zinc contents after processing, and the effects of decortication, steeping/fermentation ...
-
Kruger, Johanita; Stuetz, Wolfgang; Frank, Jan (American Chemical Society, 2019-05)Green leafy vegetables have low β-carotene bioavailability, which we hypothesized to be, at least in part, due to high contents of fiber, minerals, and phenolics. We investigated the effects of pectin (40–120 μg/mL), iron ...
