Are our tastes formed in food even before we are born?

Recent research may shed some light:

Researchers in Britain and France have just published the first direct evidence showing that fetuses can actually taste and smell while in the womb. These important findings could help scientists increase our understanding of how human taste and olfactory receptors develop. But the most immediate implication is that a pregnant woman’s diet may influence her children’s food preferences after birth.

“A number of studies have suggested that babies can taste and smell in the womb, but they are based on postnatal outcomes while our study is the first to see these reactions before birth,” said lead researcher Besa Auston, University of New York’s Embryo and Newborn Research Laboratory. Durham, in a statement.

“As a result, we believe that this frequent exposure to flavors before birth can help determine food preferences after birth, which may be important when considering messages about healthy eating and the possibility of avoiding ‘food discomfort’ at weaning.”

The reactions of children at week 32 and 36 to different flavors in the amniotic fluid were recorded on the ultrasound film:

Pregnant women and their fetuses based in North East England participated in this study from 32 to 36 weeks’ gestation. Fetuses exposed to carrot flavor (n = 35) showed more “lip angle puller” and “laughing gestalt” more frequently, while fetuses exposed to turnip flavor (n = 34) showed more “upper lip lift”, “lower-lip inhibitor” ‘, ‘lip lift’, ‘lip compress’, and ‘crying gestalt’ compared to the carrot group and the control group that were not exposed to any flavors (n = 30). Facial gestalt complexity increased from 32 to 36 weeks in the case of turnips, but not in the case of carrots. The results of this study have important implications for understanding the early evidence of a fetus’s abilities to sense and distinguish between different flavors.

The authors also note that “the amniotic fluid is the first place where fetuses begin to sense their environment, specifically their chemical environment (Brumley and Robinson, 2010). This experience provides continuous sensory information, such as taste and smell, from fetal life to neonatal life (Mellor, 2019). Schall, 2005). Continuity, based on early dating, allows newborns to adapt to their postnatal environment (Mellor, 2019).

Nutrition is a big topic these days, which raises medical concern about it Urban food deserts: “Food deserts are areas where people have limited access to healthy and affordable food. This may be due to low income or having to travel farther to find healthy food options.”

Science writer Puyo notes, “Researchers argue that frequent prenatal exposure to certain flavors may shape a baby’s nutritional preferences, so eating healthy but not very appetizing foods (yes, like kale) during pregnancy could be a viable strategy for mothers to promote healthy diets from for their children.” He adds, more study is definitely needed. But it may be best for the baby to start winning eating habits before birth.

Ignorance of life before birth

One difficulty is the pervasive ignorance of life before birth. An example from Today’s News is Georgia Governor Stacy Abrams’ claim that there is “nothing” like a fetal heartbeat at six weeks gestation.

However, just months ago, Planned Parenthood’s website said that “the beating heart and blood circulation are very fundamentally developing” during the fifth to sixth week of pregnancy.

Planned Parenthood later modified its website to more closely reflect pro-abortion messages against heart rhythm laws, which ban abortions once a fetus’s heartbeat is detected. Now the site says “part of the fetus begins to show cardiac activity” during that time.

The mainstream media has helped increase pro-abortion messages about fetal heartbeats. In May, after a leaked Supreme Court draft opinion suggested the court was about to overturn Roe v. Wade, NBC News reported that experts say the term “fetal heartbeat” is “misleading and medically inaccurate.”

However, the article quotes a quote from a doctor who says the heart “begins to develop in about six weeks” but argues that “at this point, the heart as we know it is not yet there.”

Here is an ultrasound scan of the human heart/heartbeat of that age group:

It would not be possible for a human to live long without a heart once the body has a large number of cells and systems in the making, so the heart actually begins to form in about three weeks.

The heart changes with its growth and age. The most shocking change at birth occurs when the mother’s supply line to everything essential to life is suddenly cut off and the heart is defending itself on behalf of the whole body.

Lack of information or the spread of incorrect information about prenatal life may make it more difficult to meet health needs in the long term.

NB: Kale needs a PR team. It offers specific health benefits but should be treated as cabbage and not lettuce.
