Our second brain
We have a second brain in our guts. Known as the enteric nervous system, it consists of a mesh-like network of around 100 million neurons lining the entire gastrointestinal tract. These neurons include a range of cell types operating via a complex system of circuitry largely independent of the central nervous system.

The eating of insects, or entomophagy, is not a new concept. In fact, insects have been eaten around the world since prehistoric times.
A history of insect consumption
Stable carbon isotope analysis of the bones and dental enamel of australopithecines, for example, has shown that they were significantly enriched in isotope 13C, suggesting that the diet of these people was largely composed of animals feeding on grasses, including insects. Termites are reported to have been included into the Plio-Pleistocene hominin diet, and an analysis of fossils from caves in the USA and Mexico showed that coprolites from caves in Mexico contained ants, beetle larvae, lice, ticks and mites, providing further evidence for entomophagy in human history.

If you want your toddler to be a healthy weight you might control portion sizes or the frequency of their meals and snacks. Of course, you could use both of these strategies, but a study we recently published found that one strategy is likely to be much more effective than the other depending on the traits in appetites of individual children.

New nutritional therapies are aimed at boosting the variety of microorganisms that live in your GI tract, says neuroendocrinologist Mark Heiman.
Since the discovery that dietary saturated fats increase plasma cholesterol levels, low fat foods have been an important area of research, mainly because a link was assumed between plasma cholesterol levels and cardiovascular disease risk.
Recent studies have suggested that the connection between saturated fat intake and cardiovascular health is more tenuous than was previously thought. Despite this, advisory bodies, such as the British Heart Foundation, still recommend that people should avoid saturated fats as much as possible and eat small amounts of polyunsaturated fatty acids and monounsaturated fats.
