Teens with high-fat di­ets have breast can­cer risk

The Sun (Malaysia) - - ZEST -

A NEW US study has found that con­sum­ing large amounts of sat­u­rated fat or low amounts of mono- and polyun­sat­u­rated fats dur­ing ado­les­cence is linked to higher breast den­sity in young adult­hood, a strong risk fac­tor for breast can­cer.

As breast tis­sue is most sen­si­tive to dif­fer­ent ex­po­sures dur­ing the teenage years, when breasts are de­vel­op­ing, the team wanted to look into a pos­si­ble link be­tween fat in­take dur­ing this time and breast den­sity in early adult­hood.

The team an­a­lysed data from 177 fe­male par­tic­i­pants who had their diet as­sessed be­tween the ages of 10 and 18.

A fol­low-up study to mea­sure breast den­sity was car­ried out when the par­tic­i­pants were 25 to 29 years old.

Af­ter tak­ing into ac­count var­i­ous fac­tors in­clud­ing race, ed­u­ca­tion, adult­hood fat­ness, num­ber of live births, and en­ergy and pro­tein in­takes, the re­searchers found that a higher in­take of sat­u­rated fat and lower in­takes of mono- and polyun­sat­u­rated fat dur­ing ado­les­cence were both as­so­ci­ated with a higher per­cent dense breast vol­ume (DBV) in early adult­hood.

Women who were in the high­est quar­tile of sat­u­rated fat in­take had a mean per­cent DBV of 21.5%, com­pared with 16.4% for those who were in the low­est quar­tile.

Sim­i­lar dif­fer­ences were found for those in the low­est ver­sus the high­est quar­tile of mo­noun­sat­u­rated fat in­take.

Sat­u­rated fats are com­monly found in meat and dairy prod­ucts like fatty meats, cheese and but­ter, while nuts, olive oil and av­o­cado are among com­mon sources of mo­noun­sat­u­rated fats.

Se­ungy­oun Jung, one of the study au­thors, com­mented that be­cause an in­crease in breast den­sity is as­so­ci­ated with an in­creased breast can­cer risk, the study’s re­sults, if con­firmed, could be of in­ter­est re­gard­ing breast can­cer risk in later life. – AFP-Re­laxnews
