Some like it hot. But a new report from the World Health Organization suggests that when it comes to beverages such as coffee, liking it too hot may increase the risk for esophageal cancer.

The warning follows an exhaustive review of studies on coffee, tea and cancer by the WHO's International Agency for Research on Cancer. A working group of 23 scientists declared that drinking beverages hotter than 149 degrees is "probably carcinogenic to humans." However, the report makes clear that it is temperature that makes an espresso, cappuccino or plain old cup of joe risky — not the coffee itself.

Nations face both malnutrition, obesity

Twenty countries are triply cursed: They have serious levels of malnutrition, diet-related anemia and obesity, said the Global Nutrition Report. Only China, Vietnam and South Korea had no serious problems with any of the three indicators that health experts used as harbingers of poor nutrition: stunted toddlers, anemic young women and obese adults.

The United States, Germany and 12 other countries have significant obesity.

The report praised seven countries for making progress: Nepal for fewer stunted children; Suriname for fewer underweight children; Jamaica for fewer obese children; Peru for less female anemia and more breast-feeding; Nauru for fewer adults with a body mass index over 25, North Korea for fewer adults with a BMI over 30; and Israel for less adult diabetes.

For every $1 spent malnutrition, a nation eventually saves $16, the report found.
