Why should one cook? It seems like a waste of time if some people are to believed; it destroys nutrients and wastes energy. Eating raw is the natural way, the way nature intended the food to be eaten. It sounds fancily accurate enough to convince many people, but is it the truth?
Nature’s intentions
If we go according to what we know, it is presumptuous to assume
that nature produces food to be consumed by humans, or that it does anything
with the intention of benefiting us humans. We have been here on this planet
for an infinitesimal fraction of time, nature was here much earlier, and it has
produced a lot of stuff that will kill us if we consume it. Of course, this
whole argument collapses if you don’t believe what the guys sitting in their
fancy labs are proving.
Nutrient
loss
Baking or frying food at high temperatures does indeed result in some
loss of nutrients, a chunk of water soluble vitamins are lost when food is
cooked, especially when it is overcooked. But then, in numerous cases cooking
also destroys anti-nutrients that inhibit the process of absorption of
nutrients in the gut.
Also, the loss of nutrients is nowhere close to the high
percentages proclaimed by the proponents of raw food diets. Take for example
raw broccoli and steamed broccoli, close to 25% vitamin C and 20% selenium
present in raw broccoli was destroyed during cooking, however, all the other
common nutrients showed minimal change.
In case of some vegetables such as asparagus and carrots, and the
red fruit tomato, cooking increases the availability of some the advantageous
antioxidants present in them. Eating cooked asparagus will give you more
ferulic acid than the raw ones; cooked carrots will provide more beta-carotene,
which is converted to vitamin A. Cooking tomatoes breaks down the cell walls,
increasing the absorption of lycopene.
Breakdown
of enzymes while cooking
Another misconception of some of the raw food proponents is that
the breakdown plant enzymes, which happens when they are overcooked, increases
the amount enzymes required in digesting them. Even though the plant enzymes
are beneficial for us, they do not speed up the process of digestion when
consumed; they are absorbed by our digestive juices, like other nutrients.
In fact, vegetable soups and steamed vegetables are easier to
digest; the cell structure of the plant is altered by cooking, cellulose is
also broken down, which means that fewer enzymes are required to digest them.
Cooking
meats
Not only is cooking meats essential in order to minimize the
chances of food poisoning, research has shown that cooked meat, and also cooked
sweet potatoes, provide more energy than the raw ones. The preference tests
conducted on hungry mice showed that they had a strong preference towards
cooked food. It is highly doubtful that that was because of the seasonings they
put on the cooked food. It suggests that the subjects were aware of the energy
benefits of eating cooked food.
So
cooking is better than eating raw?
It is not possible to answer this question with a straight forward
yes or no. Cooking meat, poultry and seafood is definitely beneficial and
should be the preferred method. However, when it comes to vegetables and
fruits, it essential to eat them in sufficient quantity. Some vegetables and
fruits are better off cooked, some are not.
Unless you are open to put in the effort and make a chart for the
better way to consume the common produce, or pay someone to do it for you,
eating a variety of produce is what matters. If you have trouble eating raw
broccoli, you will still gain a majority of benefits by eating steamed
broccoli.
