Coconut sugar "toddy" was reduced. Although its use has become more common in developed countries, where it may be perceived as a natural sweetener, there is no scientific evidence that coconut sugar is more nutritious or healthier than any other sweetener. The nutritive value is similar to the empty calories found in table sugar or brown sugar. The major component of coconut sugar is sucrose (70–79%), glucose, and fructose (3–9% each). The glycemic index (GI) of coconut sugar was reported by the Philippine Coconut Authority to be 35 and by that measure is classified as a low glycemic index food. However, the
Proper time arc length of world lines in four-dimensional spacetime. From the mathematical point of view, coordinate time is assumed to be predefined and we require an expression for proper time as a function of coordinate time. From the experimental point of view, proper time is what is measured experimentally and then coordinate time is calculated from the proper time of some inertial clocks. Proper time can only be defined for timelike paths through spacetime which allow for the construction of an accompanying set of physical rulers and clocks. The same formalism for spacelike paths leads to a measurement of proper distance
