Document Summary

Low blood glucose = poor brain function (require it for a brain fuel source) High blood glucose (lt) = damage to blood vessels and nerves. Physiology adapted to be optimal in an environment of food scarcity. Adapted to be able to take up nutrients, store energy (fat), use as required to stay alive for periods without constant food. Now abundance of food so fat storage is less desirable = growing rates of obesity. Huge variability (ie. change diet with age to maintain weight), social inequality (ie. Obesity = having high amount of body fat in relation to lean body mass. Bmi + waist-hip ratio. over 600m ppl worldwide obese, over 2b overweight. Re ects excessive caloric intake relative to energy expenditure. De nition: any substance in food used by the body to promote normal growth, maintenance and repair. Carbs (carbon and water) - sucrose, fructose (worst), glucose (our major energy source).
