Good fats :facts about fats
acts about fats
The indisputable fact is that the
fat is part of any diet. The world is spending millions of dollars to indicate
the ill effects of saturated fats of animal origin, and on the other side
well-being of vegetable oil.
Here are some facts about fats that you have not yet heard and it’s good to know. It will be hard to think outside normal, but stay with us… can be interesting (you will find some good fats...)
Saturated fats
Products of animal origin are the main source of saturated fat in our diet. You will be surprised by the fact that actually coconut and palm oil have a maximum saturated fatty acids in themselves (92 and 50%)
In the human body 50% of the
membrane of each cell consists of saturated fats. Together with proteins those
cells give strength and integrity. Also, saturated fats have a very important
role in bone health. It is also important as a source of vitamins A and D. The
saturated fatty acids have important antimicrobial effects and protect us from
microorganisms in the intestine that cause disease. For all these, saturated
fatty acids have to make up 50% of total fats we consume during the day.
Cholesterol
This form of fat is normally
defined as a “bad guy”; something which should be reduced to a minimum and
avoid as much as possible. Yet cholesterol is also one of the most important
components of the cell wall. When you are infected (cold, etc.), the needs for
cholesterol are increasing and your body (liver) itself will produce
cholesterol as it is necessary for the
fight against the virus / bacteria. Similarly happens with regular
training in the gym – constant damage
and recovery of muscles that regularly
occur in the training process and require regular renewal of the cell walls.
Another important role of
cholesterol is in the synthesis of
corticosteroids. They’re defending us from serious illnesses such as cancer and
heart disease. Testosterone is also produced from cholesterol. This form of fat is important for effect of serotonin –
the hormone of happiness.
Unsaturated fats
Unsaturated fats are divided into
poly and monounsaturated. Polyunsaturated are divided into two groups of
essential fatty acids (EFA): omega-3 and omega-6 essential acids, which we must
enter through food because our organism cannot create them.
Omega-3 EFA are essential for
energy, transfer of oxygen, making hemoglobin, the synthesis of cell membranes,
muscle recovery, growth, cell division and
immunity.
Adequate omega-3 EFA are necessary
for brain development and is most important
for babies and children. Sources of high-quality omega-3 EFA are green leafy
vegetables, fish oil, fatty fish, eggs, nuts, flax seed and flax seed
oil.Omega-3 EFA are essential for energy, tranfer of oxygen, making hemoglobin,
the synthesis of cell membranes, muscle recovery, growth, cell division
and immunity. These EFA are very
important for us earlier because they can help with wound healing, provide
smooth skin, make us a vital and settled. It also reduces inflammation, reduce
water retention, preventing an increase in blood pressure and the occurrence of
certain types of tumors. The lack of omega-3 EFA leads to asthma, heart disease
and problems with memory and learning.
Omega-6 EFA are somewhat worse for
us. They stimulate inflammation, reduce
the work of the thyroid gland, slowing metabolism. People whose diet contain
large amounts of EFA have a better chance of thrombosis, digestive problems,
infertility and even the risk of developing tumors.
All the unsaturated fatty acids
are considered to be very unstable at the temperatures, and should not be
warmed (roasting in oil and the like.). Cooked EFA creates free radicals that
attack the tissues and cells leading to a wide range of diseases.
The omega-3 and omega-6 EFA are
very important. They need to be in certain ratio about 1:4 in favor of omega-3
EFA.
So what do you eat? The best source of fat are plants and animals grown in the countryside or in households. In these cases, the cattle eat healthy, organic food, not receiving antibiotics, and the plants have no pesticides and herbicides (or at least contain less the same).
Farm animals are grown to the
principles of quantity and to save time and increase production, practically
100% of the animals eats food with antibiotics and hormones and food full of
pesticides and herbicides.
So try to buy food grown in home
conditions, the small farms. Keep the meat
roasted on the grill or in the oven, avoid fried foods. All nuts and
seeds, walnut, almond, sunflower and pumpkin are rich in good EFA. Also try to
make olive, fish and flaxseed oil part
of your daily diet.
