Leptin can help you lose weight?

Image
Leptin is a small hormone produced by the adipose tissues (fat cells) in our body and functions as a signal for the amount of fat present in the body. Depending on the 'Leptin' signal received, the brain can instruct our stomach to stop demanding food or our mouth to stop eating, thereby reducing food intake. So, in theory, more the amount of leptin in your body, lesser will you eat and it would be a a breeze to keep your weight in control. Of course, there is a catch.
The effect of Leptin was discovered in 1994 in a study involving voraciously eating obese mice. When these mice were given leptin injections, their craving for food dropped and they returned to normal body weight. So, scientists attempted to cure obesity in humans with the help of leptin injections. But, during trials, large amounts and frequent doses of leptin had to be injected to gain significant weight loss in highly obese patients. Also, large doses resulted in redness of skin at the site of injection for c…

Allergies and The Hygiene Hypothesis

Image
Have you ever gone to a kid’s birthday party and every time someone got up for the food table the host would go on with a list of what could be probable allergens in the dish? With kids today being allergic to perpetually everything (except junk food), throwing a birthday party may be the worst nightmare for any host! But all jokes apart, anyone would have noticed that the list of allergies seems to be getting more and more bizarre.
Our connection with microbes
Our tiff with the microbial world kick starts quite early in our neonatal life. When the fetus is growing inside its mother’s womb, it is protected from this microbial world. After it is born, it gets introduced into a different environment- one abundant in microbes. These microbes rapidly colonize the gut and respiratory tract, to the extent that at the cellular level they exceed human cells by ten times! But these microbes are actually beneficial to the human body. They provide a constant stimulus for the development and matu…

You are what you eat

I’m sure all of us must have, at some time or the other, been drilled to eat our veggies, because they were undoubtedly the healthiest anything could get. But recent scientific studies say that this belief may not be entirely true. Although veggies help in improving eyesight, providing nutrition, etc. the genomes of these plants are believed to have a negative impact on human health.

A study done by a Chinese team indicated that micro RNAs present in vegetables enter the human bloodstream after consumption. Genomes of plants were observed to have health consequences, and some bio molecules were observed to be active even after digestion!

The team tested hundreds of volunteers for a study and, nearly 50 types of plant micro RNAs were found present in the blood samples of the volunteers. In the study it was also observed that the molecule MIR168a commonly found in rice, paired with human RNA led to removal of unwanted LDL cholesterol present in the bloodstream.

So, all is not bad after all…

6 fun facts about food you should know before you eat your next meal!

Image
We have long known that food and nutrition is a science in itself, and like every science, eating food and the assimilation of nutrients also has a formula to it, if not done right and with the right coupling agent, can be useless, and render absolutely nothing.

This may come as a revelation for you, but scientists have been working on right combos, for a while now. There have been a number of studies done and experiments carried out on both mice and human, that have led to various discoveries about nutrition and food about the importance of eating not only the right food, but eating it the right way.

Here are some fun facts that’ll get you thinking

The consumption of coffee or tea during a meal reduces the body’s uptake of iron from food in comparison to a glass of orange juice that actually doubles the uptake. (J.M. Bourre, Vol 10. Number 5 Journal of Nutrition Health and Aging, 2006)
Animal protein (milk, cheese, curd, meat etc.) increases the uptake of iron from food, than protein fro…
