This week a study links increased nightly fasting to reduced risk of developing breast cancer, the possible protective effect of flavonoids naringin and rutin against short-and long-term memory defecits, and BANT members benefit from 50 per cent off tickets to The Sugar Reduction Summit on 22nd September.
Prolonged nightly fasting and breast cancer prognosis
Inspired by promising animal trails, a prospective study by The University of California published this year in JAMA Oncology revealed that women who fast for less than 13 hours a night might increase their risk of mortality from breast cancer. Data was used from 2413 women with early-stage breast cancer who participated in the Women’s Healthy Eating and Living study. The mortality rates and recurrences of breast cancer where compared in two groups of women: those who fasted for less than 13 hours, and those who fasted 13 hours or more. Women who fasted less than 13 hours had increased risk of breast cancer recurrence, while those who fasted for more than 13 hours had no increased risk of breast cancer or all-cause mortality. Interestingly, each two-hour increase in nightly fasting duration was linked to significantly reduced haemoglobin A12 levels and longer sleep. The mechanism suggested was based on improvements in glucoregulation and sleep. this may provide a simple strategy for reducing breast cancer risk. Read the paper here
The potential protective effect of naringin and rutin on memory
An animal study published earlier this year by Manipal University in India suggests that the flavonoids naringin and rutin exert protective cognitive effects. This dose-dependent outcome seem to result from the reversal of short- and long-term episodic memory deficits. Wistar rats were given naringin and rutin at two doses for 15 days before and during the trial. The animals were observed doing novel object recognition tasks (NORT) and were monitored for any change in locomotor ability. Animals given higher doses of the flavonoids showed significant improvements doing recognition and discrimination indices compared to control. The authors suggest part of the procognitive effect may result from interactions of the flavonoids with intracellular signalling affecting vascular function, synaptic plasticity and neurogenesis in addition to their antioxidant power. The active compounds in naringin and rutin are narinenin and quercetin. Read the paper here
The Sugar Reduction Summit: Industry, Regulation and Public Health – on Thursday 22 September 2016 at the Royal Society of Medicine
Those who took a particular interest in the Government’s strategy for tackling Childhood Obesity may want to consider registering for this event in September. It is the third annual Sugar Reduction Summit which includes talks from leading speakers and debates about the feasibility and ability of regulations, including advertising, EU changes to labelling and sugar tax. The day will also involve exploring the impact of voluntary measure and examining the role of sweeteners in reducing sugar dependency. The Summit starts at 8.55 am, finishes at 5.15 pm and costs £195 including 50% discount and lunch. View full details and register here cheap air max 97
