Sandi Peterson, group worldwide chairman, Johnson & Johnson
Johnson & Johnson’s boss Sandi Peterson is in fourth place on the list.
She leads the firm, whose food brands include sugar alternative Splenda, yogurt drink Benecol and dairy brand Lactaid.
She has responsibility for $20bn (£12bn) in revenue and more than 70,000 employees –more than half of the firm’s total workforce.
Earlier this year, Johnson & Johnson was forced to recall batches of its Benecol product, because of a possible yeast fermentation.
