A living cell has certain requirements to function. It must have a source of fuel. That fuel can be sunlight, carbohydrate, fat or protein (but sometimes it can be odd things like sulfide molecules or metal ions). It also needs a bag to hold it together. That bag is made of fat molecules in the same arrangement, called a bilipid layer. These fats arrange themselves in such a way that movement of chemicals in and out of the cell is controlled. All cells: plant cells, animal ce
Everyone knows that exercise is good for you.

In 2008 there was a meeting in Mexico City of the representatives of the global dairy industry.

Once the food is ready, I enjoy my freshly cooked meal. I then freeze the leftovers in containers that hold one or two servings. If it’s a meal that improves after a night in the fridge (
Some people have adopted a lackadaisical attitude toward healthy eating and exercise. Some people even think that your body only has a certain amount of energy and that exercising regularly depletes that store so that it is bad for you. In December of last year, the New England Journal of Medicine published an amazing article that didn’t get much media attention. In it, the Harvard University authors looked at four different studies which had collected blood from participants
