(Add sales at business segments, 2018 forecast)
Feb 8 (Reuters) - Kellogg Co's sales topped analysts' forecasts in the fourth quarter, as the cereal maker benefited from the acquisitions of protein bar maker RXBAR and Brazilian food group Parati.
Kellogg said on Thursday net sales rose 3.6 percent year-over-year to $3.21 billion in the quarter ended Dec. 30, exceeding analysts' average estimate of $3.08 billion, according to Thomson Reuters I/B/E/S.
The Battle Creek, Michigan-based company reported a net income of $428 million, compared to a net loss of $53 million a year earlier, when it took a charge to deconsolidate its Venezuelan unit. Excluding one-time items, Kellogg earned 96 cents per share, meeting analysts' estimates.
Sales from Kellogg's North America unit that comprises frozen foods, nutritious foods unit Kashi, and RXBAR, rose more than 9 percent to $412 million.
Sales at Kellogg's U.S. morning foods and snacks businesses both declined.
Kellogg's key cereals business has suffered for several years as people seek foods with lower sugar.
For 2018, Kellogg expects net sales to remain unchanged year-over-year. Adjusted earnings are forecast to increase 9 percent to 11 percent, with the recent U.S. tax reform contributing 5 to 6 percentage points of growth. (Reporting by Sangameswaran S in Bengaluru; Editing by Sai Sachin Ravikumar)
