Higher crude oil prices amid escalation in the Iran war and strong demand for biodiesel supported palm and soy oil prices, though rapeseed and sunflower oil declined. Sugar prices rose 5.6% on weather concerns in Europe and Asia and expectations of stronger ethanol demand in Brazil. In contrast, meat prices fell 2.8% from a record high in June, FAO said. Poultry, pig and bovine meat prices declined, though sheep meat prices reached a record high amid tight export supplies in Oceania. The FAO's overall food price index reading for July was slightly above a previous three-year high in April.
