Pregnancy’s Daily Cuppa Coffee Could Be Endangering Your Child’s Heart

Drinking just two cups of coffee a day during pregnancy can damage the heart of offspring for a lifetime.

Women could be risking their child’s weak heart for a lifetime if they insist on the regular two cups of coffee a day during pregnancy. The reason? Caffeine during pregnancy affects heart development and function, says a study published in the FASEB Journal.

According to the research, the equivalent of one dose of caffeine ingested during pregnancy may be enough to affect fetal heart development and then reduce heart function over the entire lifespan of the child.

Study Says Energy Drinks may Be Health Hazards in Disguise
They claim to improve performance, increase concentration, and stimulate metabolism, however the highly caffeinated, sugar-laden energy beverages are harmful for people's health, suggests a new study.

In addition, the researchers also found that this relatively minimal amount of exposure may lead to higher body fat among males, when compared to those who were not exposed to caffeine. Although the study was in mice, the biological cause and effect described in the research paper is plausible in humans.

According to Scott Rivkees, Yale's Associate Chair of Pediatric Research and a senior researcher on the study, "Our studies raise potential concerns about caffeine exposure during very early pregnancy, but further studies are necessary to evaluate caffeine's safety during pregnancy."

To reach their conclusion researchers studied four groups of pregnant mice under two sets of conditions for 48 hours. The first two groups were studied in "room air," with one group having been injected with caffeine and another injected with saline solution. The second two groups were studied under conditions where ambient oxygen levels were halved, with one group receiving caffeine and the other receiving saline solution.

Coffee Reduces Risk of Breast Cancer in BRCA1 Mutation Carriers
women with a BRCA1 gene mutation, which puts them at high risk for breast cancer, could actually benefit by drinking large amounts of coffee.

They found that under both circumstances, mice given caffeine produced embryos with a thinner layer of tissue separating some of the heart's chambers than the group that was not given caffeine.

The researchers then examined the mice born from these groups to determine what long-term effects, if any, caffeine had on the offspring. They found that all of the adult males exposed to caffeine as fetuses had an increase in body fat of about 20 percent, and decreased cardiac function of 35 percent when compared to mice not exposed to caffeine.
