We often hear the so-called vegetable oils '' heart-healthy "on advertisements, but actually, they are heart-damaging; they often contain hidden trans fats and high amounts of omega-6 polyunsaturated fatty acids, which are known for their provocative actions on the body and constricts the blood vessels, companies claim that they lower cholesterol in your blood, it's true, but cholesterol isn't the problem for decades of primitive populations thriving on animal fats which are high in good HDL cholesterol and reasonable amounts of omega-3 fatty acids, heart diseases are almost unknown before the introduction of processed vegetable oils, and also many recent studies have found no association of heart diseases with cholesterol, so you not need to worry about animal fats being high in cholesterol.
1. High amounts of omega-6 fatty acids
Our body needs both omega-6 and omega-3 fatty acids in our diet because we can't produce them; their ratio is to be maintained at 1:1 in our body and should not exceed 4:1, almost in equal amounts to claiming lipid profile. Vegetable oils except for coconut, olive oil, and flaxseed oils have these ratio's ranging from 10:1 to 40:1 and have significantly fewer amounts of anti-inflammatory omega-3 fatty acids, which are primarily found in animal-derived fats like grass-fed butter and ghee and all seafood products, remember plant-derived omega-3s are converted only 1% into essential Epa and DHA's. Below is the chart of vegetable oils :
This clearly shows high amounts of omega-6 fatty acids, which causes inflammation in the body if not provided along with anti-inflammatory omega-3 fatty acids.
2. Vegetable oils are pro-inflammatory
Prolonged consumption of high amounts of omega-6 fatty acids can lead to complications like hypertension, thyroid, diabetes, and heart diseases; below is the amount of omega-6 to omega-3s in population around the world :
Population. . . . . Omega-6/omega-3s ratio
Paleolithic. . . . . . 0.79
Greece(before60s). . . . . . . . . 1.00-2.00
Current Japan. . . . 4.00
Current UK. . . . . . 15
Current USA. . . . . 16.74
Current India, rural.. 5-6.1
Current India, urban.. 38-50
>India accounts for 60% of the world's heart attack deaths because of high omega-6s in the urban population and other risk factors
3. Most of them are refined and have little nutritional value
Most of the seed oils are refined to enhance the production of these oils; companies use five steps of refining :
1. Degumming
2. Neutralization
3. Bleaching
4. Deorderization
5. Winterization
and heating in high temperatures up to 200 °C, which remove phytonutrients
4. Vegetable oils are almost non existing before the 19th century
When the population rose in the 19th century, there is a significant concern of food security around the world, so by industrialization, we started producing oils by seeds and using chemicals to enhance their production; before that many cultures are consuming mostly oils high in monounsaturated and saturated fats and animals fats high in omega-3s and low omega-6 contents
5. Usage of carcinogenic chemicals in refined vegetable oils
The processing of refined oils involves adding orthophosphoric acids and hexane, which are human carcinogens, and synthetic vitamins, which are entirely different from whole food-derived vitamins.
Conclusion:
You should not completely stop the omega-6s; instead, use oils that have omega-6 to omega-3s up to 4:1 like lard, tallow, butter, or ghee in your cooking or taking fish oil supplements, flaxseed oil is only suitable for salad dressings, not for heating, coconut or MCT is also a good choice for cooking, but they didn't have omega-6 and omega-3 fatty acids. If you cannot maintain omega-3s in your diet, take fish oils supplements after consulting with your doctor.
