PepsiCo's product line ranges from salty chips and its sugary namesake drink to more healthful fare like hummus and yogurt. In 2010, the company announced plans to cut sugar, fat and sodium in its products to address health and nutrition concerns.
Many big food companies are caught in a dilemma these days. They want to rebrand themselves as merchants of health — Coca-Cola's new anti-obesity ads are just the latest example — but many of their profits still come from products that make nutritionists scowl.
If there's one person who symbolizes this tension, it's Derek Yach.

The uprisings of the Arab Spring unleashed a new political force in the region — Salafis. These ultra-conservative Muslims aspire to a society ruled entirely by a rigid form of Islamic law. Their models are the salaf, or ancestors, referring to the earliest Muslims who lived during the lifetime of the Prophet Muhammad.
To their critics, the Salafis are religious fanatics who are trying to drag the region back to 7th-century Arabia. But the Salafis maintain that they are offering the purest alternative to the dictatorships that have long dominated the region.

DEA Special Agent Paul Roach says federal law does not distinguish between hemp and marijuana.
With recreational marijuana now legal in Colorado, small-scale pot shops will open up soon in places like Denver and Boulder. But that's not the only business that could get a boost: Large-scale commercial farmers may also be in line to benefit.
Why? When Colorado voters legalized marijuana last November, they also legalized hemp.
In California in the early 1980s, a cracked tooth sent Mike Williams to the dentist's office.
When Williams asked to see the tooth, the dentist said he had a mirror but that there was no camera or anything to show people the insides of their mouths. So, Williams invented one: the first intraoral camera.
His invention was a big success, and it led to other medical technology ventures that made him millions of dollars. Williams' career as an inventor and entrepreneur took off, but it wouldn't last.
