16- and 18-carbon omega−7 unsaturated fatty acids are known to be converted into 18- or 20-carbon highly unsaturated fatty acids in the body by nonselective desaturating enzymes. [4] The same enzymes also act on omega−3, omega−6, and omega−9 fatty acids. As a result, while proportions of individual highly unsaturated fatty acids may ...
The key is to consume more “good” or healthy fats (polyunsaturated and monounsaturated fats) and fewer “bad” or unhealthy fats (saturated and trans fats), per the American Heart Association.
In foods exposed to air, unsaturated fatty acids are vulnerable to oxidation and rancidity. [2] [7] There is no high-quality evidence that dietary supplementation with omega−3 fatty acids reduces the risk of cancer or cardiovascular disease.
[23] Healthy fats include polyunsaturated and monounsaturated fats, found in vegetable oils, nuts, seeds, and fish. Foods containing trans fats are to be avoided, while foods high in saturated fats like red meat, butter, cheese, ice cream, coconut and palm oil negatively impact health and should be limited.

“Diets that lack emphasis on whole foods tend to promote ‘diet’ products that typically are low-fat versions of foods and fake sugars as the primary food sources,” Castro says. “These ...
According to a 2009 review by the American Heart Association, instead of avoiding ω-6 fats, the ω-6:ω-3 ratio should be decreased by consuming more ω-3 fats. The conversion rate of linoleic acid (LA) into arachidonic acid is very low with a diet high in linolenic acid. [11] The maximum ω-6:ω-3 ratio allowed in dog food by the AAFCO is 30: ...
On a plant-based diet, you consume mostly vegetables, fruits, whole grains, nuts and seeds, beans and legumes, fortified plant-based milk and water, along with small amounts of healthy fats ...
Some omega−9 fatty acids are common components of animal fat and vegetable oil. Two omega−9 fatty acids important in industry are: Oleic acid (18:1, n−9), which is a main component of olive oil, macadamia oil and other monounsaturated fats; Erucic acid (22:1, n−9), which is found in rapeseed, wallflower seed, and mustard seed.
