Adaptation to the pattern of food intake: some mechanisms and consequences

Abstract

I44 SYMPOSIUM PROCEEDINGS I967or father. He is followed by the other productive members of the family, i.e. the elder sons and younger brothers. Other older children come next and often the mothers and toddlers are last to be considered. Obviously a programme aimed at the toddler will fail if the type of food it receives is acceptable to the other members of the family, unless there is enough for all.T h e animal husbandman is being faced with rising costs all round and a shorter working week. He generally tries to find cheap sources of energy and protein and dietary regimes which will give a considerable concentration of these per unit dry weight. He also wishes to cash in on the most efficient periods of growth and other productions in respect of nutrient utilization. He tries to find labour-saving devices -including changes in dietary pattern-particularly at weekends, but you will hear more about all this from the experts who are with us today.

The effect of growth hormone treatment on growth in zinc deficient rats

“…This altering of the frequency of food ingestion may result in differences in nutrient metabolism and body composition (Fabry and Braun, 1967;Leveille, 1972).…”

Effects of Isolated Zinc Deficiency on the Composition of Skeletal Muscle, Liver and Bone during Growth in Rats

“…Previously, we obwhereas zinc-deficient animals fed ad libi-served that rats force-fed a zinc-deficient turn develop nibbling but cyclic patterns of diet in an amount identical to ad libitumfood intake (2,3). Studies have shown that fed zinc-replete controls became seriously ill altering the frequency of food ingestion re-in 8 d (7), and the cutaneous lesions in these suits in differences in nutrient metabolism rats were similar to those seen in patients and body composition (4)(5)(6).…”

Meal frequency and plasma lipids and lipoproteins

“…The hyperlipidaemic group consumed a significantly greater percentage of their total energy as fat (mean 34 % compared with 30 %) and less as carbohydrate (mean 49 % compared with 54 %) or simple sugars. This may be significant as it has been suggested that the composition of the background diet, particularly the carbohydrate content, may influence the metabolic response to an altered periodicity of nutrient intake (Fabry & Braun, 1976;Adams & Morgan, 1981). Differences in metabolism in normolipidaemic and hyperlipidaemic individuals may also be relevant.…”
