There are already plenty of apps that let people estimate how many calories are in the foods they're eating. However, most of these programs require users to either guess at their portion sizes, or actually weigh the food. That's where the University of Washington's NutriRay3D comes in. It's a smartphone device/app combo, that uses lasers to ascertain how many calories are sitting on the plate.
While some people take off-the-shelf supplements, others use products
that are formulated to their own unique nutritional needs. According to
the folks at Boston-based startup FitNatic, however, that's still not
specific enough. Their Nourish device keeps track of its user's states
of health and fitness, then serves up nutritional supplements that are
custom-blended on a daily basis.
We frequently hear that eating fish is a healthy thing to do, because
it's full of beneficial long chain fatty acids. Unfortunately, the
Western diet tends to be short on fish and bigger on beef, which
contains short chain fatty acids that aren't quite so good for us.
Chinese scientists are creating a work-around, however –
genetically-engineered beef that's high in the "good" fatty acids.
