How human body digests fat and oils? Which one is good for health?

What are Fats? It is one of the three main components of our food. Fats are made up of long chain organic acids called fatty acids. Fat are important for almost all hetertrophs(organism which cannot fix carbon and feed on other organism for carbon) structurally as well as metabolically. Fats are necessary for absorbing fat soluble vitamins. A small amount of fat is an essential part of a healthy, balanced diet. Fat is a source of essential fatty acids such as omega-3 – "essential" because the body can't make them itself.  Little kids, especially, need a certain amount of fat in their diets so the brain and nervous system develop correctly.That's why toddlers need to drink whole milk, which has more fat, and older kids can drink low-fat or skim milk. Cutting down on fats is not all good because you might unknowingly cut down on essentials fats for your body. Fat is not the only culprit that makes you overweight. The mechanism is fairly simple you eat more energy than your body needs the body converts into stored energy in the form of fats.

Fats and oils do not easily dissolve into the watery digestive juices of the intestinal tract. Bile, produced by the liver and stored in the gallbladder, can attach to molecules of both water and fat. Bile breaks up conglomerations of fat in the digestive tract into smaller emulsified particles, where lipase, a fat-digesting enzyme, can break it down. The broken down fat particles -- fatty acids and cholesterol -- are absorbed through the intestinal walls into the bloodstream, where they accumulate in the chest veins and are then carried to fat-deposit areas throughout the body to be stored and used for fuel when necessary.

Choosing Foods with Healthy Fats

1. Use liquid plant oils for cooking and baking. Olive, Canola, and other plant-based oils are rich in heart-healthy unsaturated fats. Try dressing up a salad or roasted vegetables with an olive oil-based vinaigrette.

2. Ditch the trans fat. In the supermarket, read the label to find foods that are trans-fat free. The label should say “0” (zero) on the line for trans-fat; you should also scan the ingredient list to make sure it does not contain partially hydrogenated oils. In restaurants that don’t have nutrition information readily available, steer clear of fried foods, biscuits, and other baked goods, unless you know that the restaurant has eliminated trans-fat—many already have.

3. Switch from butter to soft tub margarine. Choose a product that has zero grams of trans-fat, and scan the ingredient list to make sure it does not contain partially hydrogenated oils. Even better, use a liquid plant oil whenever possible; refrigerated extra virgin olive oil makes a great spread for toast.

4. Eat at least one good source of omega-3 fats each day. Fatty fish (such as salmon and tuna), walnuts, and canola oil all provide omega-3 fatty acids, essential fats that our bodies cannot make. Omega-3 fats, especially those from fish, are very beneficial for the heart. Read more about omega-3 fatty acids and why they are so important to good health.

5. Cut back on red meat, cheese, milk, and ice cream. Red meat (beef, pork, lamb) and dairy products are high in saturated fat. So eat less red meat (especially red processed meat, such as bacon), and choose fish, chicken, nuts, or beans instead. If you do eat red meat, choose lean cuts and keep the amounts low.

Low-fat and reduced-fat cheeses are often not so low in fat—and are often higher in sodium than regular cheese. So it is best to choose the cheese you like and savor it in small amounts.

Australia's Great Barrier Reef. An aquatic heaven on earth.

The Great Barrier Reef is incredibly rich and diverse. Stretching 2300 kilometres, this natural icon is so large it can even be seen from outer space.It is known mostly for its large maze of colourful reefs, but also provides a home for a huge number of plants and animals.Some of these, such as turtles and crocodiles, have been around since prehistoric times and have changed little over the course of time.

The diversity of marine creatures includes 600 types of soft and hard corals, more than 100 species of jellyfish, 3000 varieties of molluscs, 500 species of worms, 1625 types of fish, 133 varieties of sharks and rays, and more than 30 species of whales and dolphins. No other World Heritage property contains such biodiversity. This biodiversity contains many endemic species which cannot live outside ans also contains many threatened species which gives it a scientific importance.

The Great Barrier Reef is also unique as it extends over 14 degrees of latitude, from shallow estuarine areas to deep oceanic waters. It is considered as the largest living structure in the world.

Within this vast expanse are a unique range of ecological communities, habitats and species – all of which make the Reef one of the most complex natural ecosystems in the world. 

The Great Barrier Reef Marine Park stretches approximately 2300 km along the coast of Queensland in north-eastern Australia – this is about the same length as the west coast of the USA from Vancouver to the Mexican border.The great barrier reef is so big that even the combined area of United Kingdom,Switzerland and Holland is still smaller. It can also be seen from outer space. It includes world largest coral reef ecosystem.

It provides most spectacular natural scenic beauty under water full of colours and life. It is literally an aquatic heaven on Earth and thus it becomes a must visit place in a lifetime for any person who wants to feel close to mother nature underwater. 

Kjeragbolten, Only for those who have no fear of heights.

Kjeragbolten – the official name for the boulder – is located on the edge of the Kjerag mountain in Rogaland, Norway.

It is situated more than 3,500ft above sea level and is a popular photo spot for thrill-seekers who are willing to risk their lives for a memorable holiday photo. This rock is wedged between mountain's crevasse. This is accessible to tourist without climbing equipments.  there is a vertical 1000 m drop to the Fjord below-making it popular with base jumpers. People those who are brave take photographs by stepping onto the boulder.

The rocks surface is pretty flat but if you try to look down you may loose your balance.

Lets take a look at some of the pics of Kjeragbolten.

Asch Paradigm: Don't let people make you wrong.

We do something just because others do the things in the same way. To put it in simple words our actions and behaviour is guided or influenced by others' actions and behaviour.

This psychological effect is called Asch paradigm or social conformity. This me we try to seek social conformity to get social acceptance. It got its name because of the experiment conducted by the Solomon Asch a polish psychologist and in this experiment 37 % of the participant chose to answer wrong even they had known the answer was wrong because others in the experiment who was fake participants chose to give wrong answer.

The two major motives in conformity are:

1) normative influence, or the tendency to conform in order to gain social acceptance; and
2) informational influence which is based on the desire to obtain useful information through conformity and achieve a correct or appropriate result.

Several factors are associated with conformity. A few of these include:

1. Group size - individuals are more likely to conform in larger groups, although research suggests that conformity pressures peak once the majority reaches about four or five
2. Unanimity - individuals are more likely to conform when the rest of the group's response is unanimous
3. Cohesion - groups high in cohesion produce more conformity than non-cohesive groups
4. Status - individuals are more likely to conform with high status groups
5. Culture - collectivist cultures exhibit a higher degree of conformity than individualistic cultures
6. Gender - societal norms establish gender differences which affect the ways in which men and women conform to social influence; women are more likely to conform than men in situations involving surveillance, but less likely when there is no surveillance
7. Age - younger individuals are more likely to conform, perhaps due to lack of experience and status
8. Importance of stimuli - in a study where participants were told that their responses would be used in the design of aircraft safety signals, conformity decreased, suggesting that individuals may conform less frequently when the task is considered important

So if you live in a world with full of dumb people to get their acceptance you will choose to become dumb deliberately. If not them why bother, be yourself and don't let people tell you who you are.

Pain is never permanent, it eventually subsides.

We live in a world where good as well as bad things happen, which is out of our control. Good things are always acceptable but sometimes the bad things is unacceptable so much that we might consider giving up on life. But the thing is the show must go on. We must accept the things that happened and must move on with life because time only flows in one direction, so we cannot undo the happenings.

Forgetfulness is a gift given to human kind to forget something which is very painful that remains within our memory for our whole life. We cannot forget our pain no matter how hard we try to forget. Actually if we are trying to forget something, we end up remembering it. So nearly all of us lives with the pain and cope with it so that we can move forward.

There is a process described in psychology in which it is explained that how we come to an understanding with pain(Grief) no matter how bad it is , this process is called 'Five stages of Grief'.

Five Stages of Grief 

1. Denial and Isolation. At first, we tend to deny the loss has taken place, and may withdraw from our usual social contacts. This stage may last a few moments, or longer.

2. Anger. The grieving person may then be furious at the person who inflicted the hurt (even if she's dead), or at the world, for letting it happen. He may be angry with himself for letting the event take place, even if, realistically, nothing could have stopped it.

3. Bargaining. Now the grieving person may make bargains with God, asking, "If I do this, will you take away the loss?"

4. Depression. The person feels numb, although anger and sadness may remain underneath.

5. Acceptance. This is when the anger, sadness and mourning have tapered off. The person simply accepts the reality of the life and moves on.

This prayer is what keeps me inspiring and going on in life
"Lord! Give me courage to change what we can, give me strength to accept what we can't and the wisdom to known the difference between them."

What is magnetron? and Why it makes your life easy?

No, its not a name of a Transformer but it is a part of a common household thing called microwave oven. This pat is the most important part of it which generate the microwave radiation.

Today, it has become an important part of our households. You can’t imagine a kitchen without a microwave oven. But in fact I don't have one. So are we interested to know, what exactly is a microwave oven and how does it work? This article is going to answer all your questions about this amazing gadget.

Principle: Microwave radiations generated by a magnetron pass through the exposed food, create dielectric heating within the food, this is the basic principle on which a microwave oven works.

Magnetron has tens of other applications other than microwave ovens, but it’s purpose is to generate microwaves of required frequency and wavelength. Magnetron was invented by Dr. Hull (USA) in 1921. During the second world war, it was then modified to use in radar technology, later it’s application in cooking was discovered. That’s why it is generally said that, microwave oven is the only gift which war has given to humanity.

The heart of microwave oven is a device to generate microwaves of required frequency and wavelength called magnetron. Microwaves generated by the magnetron are bombarded on the food, which cook the food through a process called dielectric heating.

The magnetron generates microwave which has frequency between radio and infra-red. In common home ovens, the frequency of microwave radiation is 2.45 Ghz with a wavelength of 122 millimetres. It is to be noted that, microwaves always posses an alternating electric and magnetic field around them. When microwaves penetrate through the exposed food, they are intervened by the dipolar water molecules present within the food. As the electric and magnetic fields associated to the microwaves alternate, the individual water molecules also rotate to align their dipoles with respect to the changing electric field they are subjected to these electric and magnetic fields, alternating 2.45 billion times a second in case of a microwave oven. This causes the dipolar water molecules to rotate or simply move back and forth at a high speed, which causes vibration and thus causing molecular friction. This causes heat generation at the molecular level. This whole process works under a principle of dielectric principle.
