By Genevra Pittman NEW YORK (Reuters Health) - A new study offers evidence to support what many people have learned for themselves: never go grocery shopping when you're hungry. Researchers found that people who hadn't eaten all afternoon chose more high-calorie foods in a simulated supermarket than those who were given a snack just before online food shopping.

Caracas, May 13 (EFE).- The Venezuelan government said Monday that this week a shipment of 760,000 tons of food will arrive in the country, all of it being the product of agreements reached during President Nicolas Maduro's recent tour through countries of the Mercosur trade bloc. "On this visit to Uruguay, Argentina and Brazil we arrived at some agreements ... (for) the first month of the food reserve, which is comprised of 760,000 tons," the minister responsible for food supplies, Felix Osorio, told state television.

NIAMEY (Reuters) - Some 800,000 people will require food aid in Niger in the coming months despite a good harvest last year due to problems supplying cereals to markets, which have pushed up prices, and an influx of Malian refugees, the United Nations said. The U.N. office for humanitarian coordination (OCHA) said they would need food from now until the start of the rainy season, which is usually in July, July and August.

World food prices edged slightly higher in March, their first rise so far this year, the United Nations Food and Agriculture Organization (FAO) said Thursday, though prices stayed within the narrow price band where they have stayed since November. With rice prices almost unchanged from February, the cereals index -- the largest single component in the overall index -- was unchanged compared to February.
