Fatty fish consumption is linked to delayed precocious puberty in girls and consumption of red meat is linked to the early start of periods, a recent research finding says.

The researchers at Michigan University assessed six years data of 456 girls aged 5 and 12 years who participated in the BogotaSchool Children Cohort in Colombia and discovered that girls who consumed red meat experienced their menstruation cycle earlier than those who didn’t, whereas the ones who included fatty fish in their diets started their period cycles much later.

Research findings revealed that the time period of red meat consumption varied from less than four times a week to two times a day and girls who consumed the most red meat experienced their first onset of puberty at a median age of 12 years and 3 months. On the other hand, those who consumed less red meat experienced their first period at 12 years and 8 months.

It also proved the fact that girls who included fatty fish like mackerel, salmon and sardines in their diet at least one time a week experienced their onset of period cycle significantly later than those who consumed it once a month. Researchers found that girls who consumed fatty fish very often experienced their first cycle of puberty at 12 years and 6 months.

Researchers further said that the results are important as early puberty in girls has been associated with Type 2 diabetes, breast cancer, obesity and heart ailments. Erica Jansen, the author of the study, said that it’s a significant difference because it is linked to the risk of disease in later life and also because few dietary factors are believed to affect the early puberty timings. This study may also go on to elucidate why the consumption of red meat early in life is linked to increased risk of breast cancer at the later stage of our lives.

Dr. Eduardo Villamor, the senior author of the study, said that they cannot give any remark on the basis of this study of whether there exists a casual relation between red meat and the onset of puberty. But there is a mounting body of evidence which suggests that excessive consumption of red meat at various stages of life is connected with a number of unfavorable health outcomes, particularly to inheriting some types of cancer.

The study is issued in the Journal of Nutrition.
