New York: Anxious parents are more likely to have anxious children, a study on rhesus monkeys has revealed. It added that the risk of developing anxiety and depression is passed from parents to children.

An over-active brain circuit involving three brain areas inherited from generation to generation may set the stage for developing anxiety and depressive disorders, said the researchers from University of Wisconsin-Madison.

“Over-activity of these three brain regions are inherited brain alterations that are directly linked to the later life risk to develop anxiety and depression,” said senior study author Ned Kalin.

The findings showed that elevated activity in the brain areas is likely involved in mediating the in-born risk for extreme anxiety and anxious temperament that can be observed in early childhood.

Monkeys, like humans, can be temperamentally anxious and pass their anxiety-related genes on to the next generation.

By studying nearly 600 young rhesus monkeys, the team found that about 35 percent of variation in anxiety-like tendencies is explained by family history.

To a certain extent, anxiety can provide an evolutionary advantage because it helps an individual recognise and avoid danger.

“But when the circuits are over-active, it becomes a problem and can result in anxiety and depressive disorders,” Kalin explained.

Surprisingly, the study found that it was the function of brain structures – and not their size – that was responsible for the genetic transfer of an anxious temperament.

“Now that we know where to look, we can develop a better understanding of the molecular alterations that give rise to anxiety-related brain function,” Kalin noted.

The findings are a big step in understanding the neural underpinnings of inherited anxiety and begins to give scientists more selective targets for treatment.

The study was published in the journal Proceedings of the National Academy of Sciences (PNAS).

Fat is an important part of any balanced diet but the type of fat you eat matters the most particularly when it comes to cholesterol level so make sure you are avoiding the ones that is causing health problems.

Manoj Acharya, Food Consultant at Zappfresh and Mehar Rajput, Nutritionist and Dietician at Fitpass tells us about the foods that are full of trans fats and are harmful to our health.

* Cakes, pies and cookies (especially with frosting) : Most cakes and cookies mixes list 0 gm of trans fat on the label. But there is a catch. Manufacturers can list 0 gm if the trans fat content is under 0.5gm. Those small amounts add up when you eat multiple serving of sweets that too with frosting. An average serving of frosting contains 2 gm of trans fats, plus the same amount of sugar.

* Biscuits: This one surprises a lot of people. Biscuits contain 3.5gm of trans fats. It also contains over half of the daily recommendations of sodium.

* Margarine: Most margarine makers have removed trans fats from their ingredients. But you still must check. The few that still contains trans fats as high as 3gm per servings.

* French fries: You need to be cautious about where they fry your French fries in Vanaspati ghee or hydrogenated fat. Though certain food chains decided to turn healthier by becoming trans-fats free, you must care about it. But if you are cautious about health, you shouldn’t be having French fries.

Cholesterol -- a molecule normally linked with cardiovascular diseases -- may also play an important role in the onset and progression of Alzheimer's disease, researchers have found.

* Fried chicken: Just like French fries you need to be sure that your fried chicken has not been fried in hydrogenated oil. Same goes for fried fish.

* Frozen foods: People who are perpetually busy tend to pick up frozen meals from the supermarket. They are most likely to have trans-fat in them as they need to be kept preserved for a longer time.

* Ice creams and Indian savouries: It contains 0.5 gm of trans fat per servings. But if you read the ingredients list, the listing of partially hydrogenated oil is missing. That may be because there are naturally occurring trans fats in fat-containing dairy products which are not as dangerous as the manufactured trans fats. These products are high in calories, so one should still keep a check on their intake. Besides this, all the India savouries like Gulab Jamun, Gujhia, Laddo and Kachouri.

* Popcorns: There is a good way and bad way to eat popcorn. The snack itself is a healthy whole grain packed with fibre. It is the extra add-on that gives it that trans-fat flag. Plain popcorn is fine but when you add butter to it(which is not real butter ), it made it loaded with trans fats with no other health benefits in it.

* Non-dairy creamers: For coffee lovers, non-dairy creamers can become an integral part of their morning. Over time, however, they can also add trans-fat to your diet. One serving contains 0 gm trans-fat, yet, for some flavours, partially hydrogenated oils are the second or third ingredients listed, which can add up if you drink multiple servings in a day. So keep a check on the portion size.

* Sandwich spreads: Think twice before next time when you go out to have your sandwich with spreads if you got cholesterol concern. Trans fat occur naturally in some food like meat and While it’s not as concerning as the artificial kind added through hydrogenated oil, it doesn’t do you much good, either. Those who have heart disease, it is recommended to choose lean meat as much as possible as well as low fat or fat-free dairy products. (IANS)
