Vegetable oils like soy, corn,
cottonseed and canola are polyunsaturated fats. These fats are very unstable
(because they have several double bonds that are easily broken, making it easy
for free radicals to attack), especially when heated so they go rancid quickly.
Humans have only been consuming these oils for about 100 years whereas butter,
lard, beef tallow, coconut and olive oils have been consumed for thousands of
years. It is interesting to note that we
didn’t develop epidemic rates of heart disease, cancer, diabetes and obesity
until we stared eating vegetable oils and decreasing our intake of animal fats.
Vegetable oils are generally high in
omega 6 fats and low in omega 3 fats so if we eat a lot of them (which we do in
America because everything is made with them) we get too much omega-6 and not
enough omega-3 causing our fatty acid profile to become unbalanced. Omega-6 and omega-3 fats compete with each
other for absorption which means that a diet high in omega-6 fats will deplete
the body of omega-3 fats. This imbalance
leads to inflammation, pain and disease.
The vegetable oils you buy at the store
are most likely already rancid when you purchase them and products containing
these oils are also already rancid. We
can’t tell they are rancid because deodorizers are used to disguise the rancid
smell. Heating these oils causes even more
damage to these delicate oils which translates to more free radical production
and inflammation in the body.
Another serious problem with vegetable
oils is that, unless they are from an organic source, they are genetically
modified. Allergies have increased
significantly since we have been eating genetically modified foods and these
foods can also contribute to infertility and other problems.
The best fats to use are butter,
coconut oil, olive oil, lard, beef tallow and palm oil, with small amounts of
flax and sesame oil. These fats promote
health in the body and have nourished and strengthened humans for thousands of
generations.
