  • Male and Female Fat Tissue Highlights Differences in Health Implications

    By Alton Parrish (Reporter)

    New research from York University on fat tissue is providing an important clue as to how females stay healthier than males, even as their body fat increases.

    Published Oct. 23 in Frontiers in Physiology – Vascular Physiology, the research focuses on the differences between male and female abdominal fat in mice. A team of researchers under the direction of Faculty of Health Professor Tara Haas found that female abdominal fat had more blood vessels than the fat on males, which could be a factor in protecting the health of females as they gain fat from eating a high-fat diet.

    Males and females develop fat tissue differently and also differ in susceptibility to cardiovascular disease, insulin resistance and diabetes. However, the underlying biology behind why fat tissue in females is more protective against these conditions was not well understood, says Haas, a professor in the School of Kinesiology and Health Science.

    Blood vessels are critical for maintaining healthy fat tissue by ensuring that the expanding fat cells are supplied with enough oxygen and nutrients, so the researchers looked at whether the abilities of the fat tissue to grow blood vessels and maintain healthy fat tissue would be different between males and females.
