Some of pharmacologically active constituents of avocado.

A new review investigates the effects of avocados on different components of metabolic syndrome, which is a clustering of risk factors including high blood sugar, cholesterol, blood pressure, and body mass index. These risk factors lead to an increased risk of type 2 diabetes and cardiovascular disease.

According to studies reported in the literature, avocados have the most beneficial effects on lipid profiles, with changes to LDL-cholesterol, HDL-cholesterol, triglycerides, total cholesterol, and phospholipids. The peel, seed, flesh, and leaves of avocados have differing effects on components of metabolic syndrome.

“Avocado is a well-known source of carotenoids, minerals, phenolics, vitamins, and fatty acids,” wrote the authors of ...

New research predicts that Earth has more than 1,500 undiscovered minerals and that the exact mineral diversity of our planet is unique and could not be duplicated anywhere in the cosmos. Minerals form from novel combinations of elements. These combinations can be facilitated by both geological activity, including volcanoes, plate tectonics, and water-rock interactions, and biological activity, such as chemical reactions with oxygen and organic material.

Nearly a decade ago, Hazen developed the idea that the diversity explosion of planet’s minerals from the dozen present at the birth of our Solar System to the nearly 5,000 types existing today arose primarily from the rise of life...
