The research took eight different sample jars produced by four popular brands from the shelves of leading supermarkets and analysed the micro-nutrient content, with a tool called an Inductivity Coupled Plasma-Optical Emission Spectrometer.
The samples included four meat and four vegetable varieties, one with pasta, but specific manufacturers were not identified, the Food Chemistry Journal reports.
The research by the University of Greenwich School of Science showed that infants given one meat jar and one vegetable jar on top of 600 ml of formula milk would not be getting enough calcium, magnesium, copper and selenium. On average, the levels were below 20 percent of the recommended daily supply.
