More about fats.

Some fat is good for you. Some types of fat are good for our health and we need small percentage of fat in our diet. However, fats have high calories contents. The various types of fat are listed below.

Additional information pertaining to fats.

Fats and oils that contain primarily saturated bonds.
The source of these fats is primarily fatty meats such as bacon or sausage, lard, and dairy products such as whole milk, cream, butter, ice cream and hard cheeses. “Trans Fats” or Hydrogenated Vegetable Oils are two other types of fats. Just like saturated fats, these particular oils originated from vegatables and they become hard after getting processed. You find them frequently in canned and packaged meals and desserts. We should try to limit our intake of saturated fats and trans fats as they contribute to weight gain and a raised cholesterol level.

Unsaturated fats.

The main source of these fats is plants, not animals.  The categories include:

Polyunsaturated fats like corn, canola, and sunflower oil
Monounsaturated fats such as olive oil and rapeseed oil.
Omega 3 fatty acids. Primarily these are from oily fish like fresh tuna, pilchards, salmon mackerel, and sardines. Some omega 3 fatty acids are found in various plant foods and vegetable oils.

Unsaturated fats are ‘good fats’ as they are less likely to raise your cholesterol level. Omega 3 fatty acids are also thought to help prevent heart disease and may help to improve our health in other ways. Special leaflet is there as ‘Cholesteral’ which guide us in reducing the level of cholesterol
Fatty foods generally contain a combination of both saturated and unsaturated fats. The amount of food and the fat are shown in the food labels. We must make it a point to minimize the consumption of saturated fat and opt for unsaturated ones instead. Labels on food, show its calorie contents. Hence, inculcate the practice of browsing the labels when you go out to buy.
If you want to lose weight, you need to eat less calories per day than you have been eating or do more exercise. Usually eatables made up of more fat are rich in calories too. Of course, other food products also are very high in calories. The problem with sugary food is that while they do not have fat, they can still have a lot of calories. 

Fats and Oils.

   

Choose from:
Vegetable oil as first ingredient on the list, saturated tablespoons margarine or liquid vegetable oil 1, 2 grams of fat with no more than one. canola, corn, olive, safflower, sesame, soybean and sunflower oils.
Liquid or tub margarines that are low in saturated fat and trans fat. Bad cholesterol, or LDL, and overall cholesterol are both raised by trans-fats.
1 gram of saturated fat per tablespoon you can try the reduced fat and no-fat salad dressing.

Helpful advice for how to shop and prepare.
Sparingly use fats and oils. And use the ones lowest in saturated fat and cholesterol for cooking, baking and in spreads.
Use hydrogenated shortenings sparingly. Select those made from plant sources such as canola or corn. These have reduced saturated fats over other animal or vegetable fat mixtures.
For a healthier life style use reduced-fat or no fat salad dressing for dips, marinades and salad dressings.

Low-fat diet plans.

Utilize cooking techniques which don’t add much or no fat to dishes, and asked for foods cooked that way when eating out.
Don’t forget to account for the so-called hidden fats in snacks and baked goods, the fat contained in breads and vegetables, or foods cooked in fat. Read nutritional stickers on food.
Some vegetable oils for high in saturated fat, examples are coconut oil, palm oil, and pal kernel oil even though they have no cholesterol. Read food labels carefully.

There are four main kinds of fat that we consume through the foods we eat: saturated, poly- and mono-unsaturated, and trans fats. Your blood cholesterol is raised by saturated fats and trans fats. Blood cholesterol levels may also be higher due to cholesterol found in your diet. Major risk factor for coronary heart disease with high levels of cholesterol in the blood leads to heart attacks, also increase the risk of stroke.

Limit foods high in saturated fat, trans fat and/or cholesterol, such as whole-milk dairy products, fatty meats, tropical oils, partially hydrogenated vegetable oils and egg yolks. Instead choose foods low in saturated fat, trans fat and cholesterol. Here are some helpful tips:

Eat a variety of fruits and vegetables.
Make sure that an array of whole grains find their way into your diet.
It is beneficial to consume fatty fish at least two times a week.
Keep fat less and low-fat milk items, legumes, beans, skinless poultry as well aslean meats.
as liquid and tub margarines, canola, corn, safflower, soy bean and olive oils.

Saturated fat intake should not exceed 7 percent of total calories each day. Limit your trans fat to 1 percent or less of your daily calories.

Total fat intake - saturated, trans, monounsaturated, polyunsaturated - should be adjusted to fit total caloric needs.  People that are considered overweight should not consume more than 30 percent of total calories from fat.

What are saturated fatty acids?

Saturated fatty acids have all the hydrogen the carbon atoms can hold. Because of their chemical nature, saturated fats tend to be firmer at room temperature and resist the spoiling effects of oxygen longer.  Saturated fat and trans fats raise blood cholesterol is a major dietary factors. The main sources of saturated fat in the typical American diet are foods from animals and some plants.

The next lesson to learn is the meaning of trans fats. 
Trans fats may be similar chemically to unsaturated fats, but they have two major health consequences in that they lower your HDL ratio whilst simultaneously raising you LDL ratio. commercial baked goods and for cooking in most restaurants and fast-food chains.
Cookies, crackers and other commercial baked goods made with partially hydrogenated vegetable oils may be high in trans fat.

Major sources of trans fat in the diet are french fries, donuts and other commercial fried foods.

Hydrogenated fats are what? 

During food processing, fats may undergo a chemical process called hydrogenation. In case of fatty acids ‘hydrogenate’ means to add hydrogen or, to saturate The process changes a liquid oil, naturally high in unsaturated fatty acids, to a more solid and more saturated form. The saturation of a fat is corresponding to the level of hydrogenation. A lot of commercial items include hydrogenated or somewhat hydrogenated veggie oils. Certain fats have been shown to increase the cholesterol in your blood.  The fatty acid content of most margarines and spreads is printed on the package or label. The amount of saturated fat or trans fat is limited in soft tub or liquid margarines.

Explain poly- and mono- unsaturated fatty acids?

The two types of unsaturated fatty acids are Polyunsaturated and monounsaturated fatty acids. Hydrogen can be added somewhere in the molecule for all unsaturated fats. You will notice them in liquid oils derived from vegetables.
In the refrigerator, Polyunsaturated oils are liquid just as they are at room temperature. They can become spoiled when oxygen and air mix.

If you refrigerate monounsaturated oils they will begin to harden.

Polyunsaturated fats assist in eliminating recently built up cholesterol in your blood vessels. Therefore, they will help make cholesterol plaques shrink and the level of circulating cholesterol go down. According to studies, monounsaturated fats may also be beneficial to the body as long as the person has a diet that contains very low amounts of saturated fat.

Both types of unsaturated fats may help lower your blood cholesterol level when used in place of saturated fats in your diet. However, due to loose fat you eat what you all kinds of fat calories and 2 contain one or more proteins and carbohydrates times.

In place of of fats with a high saturated fat content like butter, lard or hydrogenated shortenings, one should eat margarines and spreads made from polyunsaturated or monounsaturated oil.
