Researchers and health professionals have, for long, believed that fat is the villain of many diseases including obesity, cancer and cardiovascular.
In reality, a healthy body needs fats to function properly, but there is a distinction to be made between “good” and “bad” fats. One thing is clear that fats contain more calories (1 gram= 9 calories) than carbohydrates (1gram=4 calories), but not all fats should be dismissed as unhealthy.
Chemically, fats, also called lipids, consist mostly of fatty acids and glycerol.
They are grouped into saturated and unsaturated depending on the proportion of hydrogen atoms. If fatty acids contain the maximum amount of hydrogen, they are saturated. Meat, poultry, dairy products, coconut and palm oils contain mostly saturated fatty acids, whereas olive-, peanut-, and canola oils, known as mono-unsaturated are much better. Polyunsaturated fats (corn, sunflower, and safflower oils) according to some researchers are better than both saturated and mono-unsaturated fats.
All fats contain all three categories but are grouped according to the type of fat the contain most.
Trans fats are liquid lipids that have been rendered solid by hydrogenation. They are stable, oxidize much slower than unprocessed fats and preferred by manufacturers of cookies, snack foods, fried fast foods and many manufactured bakery goods.
Most margarine consists of hydrogenated fats. Researchers determined all transfats to be unhealthy.
Polyunsaturated oils help the body to eliminate newly formed cholesterol and thus keep cholesterol levels down. There are two types of cholesterol HDL (high density lipoproteins) and LDL (Low density lipoproteins). HDL is good for you, whereas LDL is not.
Olive-, canola, nut-seed-, sesame-, soy-, corn- and sunflower oils, salmon, sardines, trout, mackerel, herring, and walnuts, avocados, pecans and soybeans are good for you.
On the other hand, meat, poultry, butter, cream, cheese, coconut-, palm- and kernel oils, fried fast foods, hydrogenated oils of all types, snack foods and commercial bakery products must be consumed in the least amounts possible or eliminated altogether.
A healthy diet consists of a variety of foods including carbohydrates, fats, proteins, and vegetables and fruits. In the Middle Ages, people ate healthier diets than today because of necessity and poverty. Their diets consisted of vegetables, fruits, legumes, little fat and much less protein in form of animal flesh. In fact, meat was a “condiment” next to vegetables. In modern day western diets meat has become the “main ingredient”, and vegetables, fruits and legumes the “condiment”.
Think of steakhouses serving 453-gram steaks with nothing else on the plate as is the case in the U S A; if you want vegetables and a potato you must order these as a side dish and pay extra!
A steady diet of greasy foods, and immobility lead to lethargy and pack on weight, as is now evidenced with young adults across the country.
After WW II the German population was starved but healthier than shortly after the economy improved, thanks to the Marshall Plan. Along with this, coronary diseases started to manifest themselves. The same is happening now in China and other developing countries.
Coronary diseases are the so-called diseases of wealth!
