AND DIETETICS ?
There are 3 major families of fatty acids.
Saturated fatty acids (found in meats, butter, milk), consumed in excess, tend to favor cardiovascular diseases by raising blood cholesterol levels. Fortunately, vegetable oils contain only a few, compared to animal fats (around 10% for most oils).
Polyunsaturated fatty acids are more interesting, especially omega-6 (linoleic acid for example) and omega-3 (alpha-linolenic acid or ALA). These fatty acids are called "essential" because our body can not synthesize them from other sources of food. It is therefore important to have some in its diet, especially thanks to vegetable oils. But omega-6, with their cholesterol-lowering properties, and omega-3 that participate, among other things, in cardiovascular protection, must be consumed in balanced proportions. Scientific studies advise an omega-6 / omega-3 ratio of less than 4: 1. However our diet is deficient omega-3 in favor of omega-6. There is a better understanding of the importance of looking for oils rich in omega-3 (the optimal ration of ALA is two grams per day).
The last family of fatty acids are monounsaturates. It is mainly oleic acid, omega-9, which takes its name from the olive oil of which it is the main constituent. Monounsaturates have a positive effect on metabolism, in particular helping to prevent cancers and autoimmune diseases and to protect against the occurrence of cardiovascular events. However in too large quantities (more than 50 g per day), some studies have shown that monounsaturated fatty acids could have the opposite effect by increasing the LDL, the "bad cholesterol".
It is therefore necessary to consume all of these fatty acids in balanced proportions. The ideal omega-9 / omega-6 / omega-3 ratio should be 10 / 2.5 / 1.
The olive and avocado oils are quite close to these proportions. These 2 oils are also very rich in antioxidants and various vitamins.
Coconut oil is quite special. Indeed it contains a rare combination of three fatty acids: lauric, capric and caprylic acid, which are among the rarest in nature. These medium-chain fatty acids (MCFAs) provide extraordinary health benefits; they are easy to burn during exercise and have antibacterial properties.
Coconut oil is particularly indicated for people who have gallbladder problems, because it is the only oil that does not require action of this organ.
We can note these benefits:
- Balance the hormonal system
- Eliminate candida
- Improves digestion
- Moisturizes the skin
- Reduces cellulite
- Attenuates wrinkles and age spots
- Balances blood glucose and improves energy
- Improves the condition of people with Alzheimer's
- Increases HDL ("good cholesterol") cholesterol and lowers LDL
- Burns fat
