* Energy versus fat
The US/Canadian nutritional tables often have an entry ''Energy from Fat''. So we would expect a correlation between energy and fat percentage. This is shown in the graph below. Both the fat percentage and the Energy (kcal) have been normalised.

There is also no correlation between the saturated fat content and the energy.

As expected there is a good correlation between the mono- and poly-unsaturated fat percentages. The normalisation worked out well.
