How much will we eat in the future?

The amount of food needed to feed the world’s population in the future is of vital importance.

Narcissists: Why we need to take better care of them

Narcissists, like sharks, get a bad press. Both are generally seen as menacing, negative forces to be feared and avoided.

How our sense of taste changes as we age

We do not experience the sensation through a single sense (as we would when we see something using our sense of sight, for example) but rather it is made up of the five senses working together to allow us to appreciate and enjoy food and drink. Initial visual inspection of

Eating more of this nutrient supports muscle strength as we age

If protein is the king of muscle mass food, nitrate might just be the king of muscle strength food. A new Australian study has found eating nitrate-rich vegetables like spinach, rocket and lettuce significantly improves muscle strength and physical function as we age. Power food … the nitrates in spinach, the vegetable which fuelled Popeye’s
