Beware Expectant Mothers! High Fat Diet May Disturb Your Child’s Mental Health

An unhealthy diet not only creates health problems for expectant mothers, but also alters children's development of the brain and endocrine system which may cause long-lasting mental health ramifications

New York, July 22, 2017: Babies whose mothers consumed a high-fat diet during their pregnancy may be at an increased risk of developing mental health disorders such as anxiety and depression, a study has warned.

The findings, of an animal study, showed that an unhealthy diet not only creates health problems for expectant mothers, but also alters children’s development of the brain and endocrine system which may cause long-lasting mental health ramifications.

“Given the high level of dietary fat consumption and maternal obesity in developed nations, these findings have important implications for the mental health of future generations,” said Elinor Sullivan, assistant professor at the Oregon Health and Science University (OHSU) in the US.

Further, exposure to a high-fat diet during gestation and early in development impaired the development of neurons containing serotonin — a neurotransmitter that is critical in developing brains.

On the other hand, introducing the child to a healthy diet at an early age also failed to reverse the effect, the researchers said.

“It’s not about blaming the mother,” but “about educating pregnant women about the potential risks of a high-fat diet in pregnancy and empowering them and their families to make healthy choices by providing support. We also need to craft public policies that promote healthy lifestyles and diets,” Sullivan noted.

For the study, published in the journal Frontiers in Endocrinology, the team tested the effect of a maternal high-fat diet on non-human primates, tightly controlling their diet in a way that would be impossible in a human population.

Researchers grouped a total of 65 female Japanese macaques into two groups, one given a high-fat diet and one a control diet during pregnancy.

They subsequently measured and compared anxiety-like behaviour among 135 offspring and found that both males and females exposed to a high-fat diet during pregnancy exhibited greater incidence of anxiety compared with those in the control group. (IANS)

Do You Feel Sleepy Post-Lunch? Well, Take a Look at the Possible Reasons!

Feeling sleepy after lunch. Wish to take a nap. Heavy lunch makes you feel lethargic.

New Delhi, August 22, 2017: Have you ever wondered that from the total office hours, why is it only post-lunch that you feel like slugging away? What could possibly be the reason behind these post-lunch slumps?

Most of the people tend to grab a bite from outside eateries. They eat anything that they feel like such as pasta, bread, burger etc., without even giving a thought to what kind of food they are in-taking. Is it high in protein, carbohydrate or fat? This thought never comes to their mind.

The main reason behind this drowsiness is not the lunch but what we consume in the lunch. It is basically due to the chemical changes in the body during the digestion process that you feel sleepiness.

After the meal, our body generates insulin to regulate blood-sugar levels. The amount of insulin released primarily depends on two main factors. First, the type of meal i.e, whether it is rich in protein, carbs or fat. The other factor is the size of the meal.

If we have a large meal, then the amount of insulin released will be more and vice-versa. With the secretion of insulin, our body also produces Serotonin and Melatonin. Similar is the case with the protein-rich diet. The protein contains Tryptophan amino acids, which is used by the body to produce Serotonin.

Serotonin and Melatonin are basically neurotransmitters that have a calming effect and help regulate sleep. When they get metabolized in the brain, they induce drowsiness.

Moreover, the body streams more blood to the digestive system to digest food. If you opt for a heavy lunch, then post-lunch, your body would stream more blood to the digestive system. And for that period of time, most of your body’s energy would be used by your digestive system and not by your brain. This makes you feel lazy and forces you to go for a siesta.

So, do not opt for heavy lunch. Instead, have a heavy breakfast so as to set good energy level for the day and then eat small meals throughout the day. This is the way to adios to the post-lunch sleepiness.

Stem cells used for crucial brain chemical

New York: Researchers at the University of Wisconsin-Madison have used stem cells to create a specialised nerve cell that makes serotonin, a signalling chemical with a broad role in the brain.

Serotonin affects emotions, sleep, anxiety, depression, appetite, pulse and breathing. It also plays a role in serious psychiatric conditions like schizophrenia, bipolar disorder and depression.

“Serotonin essentially modulates every aspect of brain function, including movement,” said one of the researchers Su-Chun Zhang said.

A small number of neurons localised on one structure at the back of the brain are responsible for making this chemical.

Serotonin exerts its influence because the neurons that make it project to almost every part of the brain, the researchers said.

The study began with two types of stem cells: one derived from embryos, the other from adult cells.

As serotonin neurons form before birth, the researchers had to recreate the chemical environment found in the developing brain in the uterus, Zhang said.

Because the neurons can be generated from induced pluripotent stem cells, which can be produced from a patient’s skin cells, “these could be useful for finding treatments for psychiatric disorders like depression, where we often see quite variable responses to drugs,” study first author Jianfeng Lu said.

“By identifying individual differences, this could be a step toward personalised medicine,” Lu noted.

The findings were reported in the journal Nature Biotechnology. (IANS), (image courtesy: stemology.co.uk)
