MUMBAI (Reuters) - Nestle India Ltd reported first-quarter net profit below analysts' estimates as it struggles to regain market share of its once-popular Maggi noodles that were temporarily banned last year over safety concerns. The India unit of Nestle SA, the world's largest packaged food company, reported a net profit of 2.59 billion rupees ($38.87 million) for the January-March quarter, while analysts polled by Thomson Reuters had expected 2.87 billion rupees on average. The net profit was well below the 3.20 billion rupees Nestle India posted a year earlier, before Indian regulators found some samples of its Maggi noodles contained unsafe levels of lead.
