make the porridge on-site at a feeding centre from where patients are fed daily. With
the ‘dry rations’ option, the porridge premix is given in one- or two-weekly rations
to the care-giver of the patient for preparation at home (ACF 2011).
The traditional formulation of FBF consists of corn soy blend (CSB) with high
levels of phytates which inhibit the absorption of several micronutrients. Thus, there
has been a shift towards the use of newer products (e.g. CSB+, CSB++) which have
been modified to reduce the level of phytates (anti-nutrients). The levels of phytates
and fibre are reduced through dehulling the soybeans used in CSB+ and CSB++
(ACF 2011).
Advantages of FBF:
– It is of low cost
– Readily provides amino acids
– The blended flour ingredient is readily available
Disadvantages:
– The pre-mixing of the ingredients is a difficult procedure
– The product is bulky (i.e. it’s relatively of a high weight for the number of calories provided compared to other products)
– It is of poor nutritional quality
– Requires an addition of oil which may not be readily available
23.4 Lipid-Based Nutrient Supplements
Products which derive most of their energy supply from fats are known as lipidbased nutrient supplements (LNS). The fat content in these products are made up of
varying amounts of vegetable fat, milk powder, ground nuts or soya (ACF 2011).
The RUTF, RUSF and RUCF products discussed earlier are some of the examples
of LNS which have penetrated the therapeutic realm due to their low moisture content, less risk of contamination and long shelf life.
23.5 Product Fortification
Food fortification is the addition of nutrients at a level of higher than those found in
the original food. Infants and young children are highly vulnerable to micronutrient
deficiencies because of their high nutrient needs relative to energy intake.
Micronutrient deficiencies in early life cause damage to brain development which is
irreversible. Fetal and child malnutrition influences health throughout the life. A
number of interventions exist to improve the micronutrient intakes in early life, such
as fortification (Preedy et al. 2013).
