In this day and age it's virtually impossible to find food that hasn't been tampered with in some way so we need to just do the best we can in choosing what we eat and be sensible about it.
This sums it up, ie choose wisely and use your brain, and may be do some research into what you are actually eating before making a decision.
natural food is also a mixture of compounds... in the end, everything, even us, is made of chemicals
Yes, but I think his point is that it is a finely balanced natural combination of compounds that has developed over millions of years of evolution.
Once you (humans) mess with it you change the make up of it, and who knows what affect that will have??
Margarine starts off as a flower or plant and then gets processed into something entirely different, while butter is just butter (cream).
This seems to be on topic but here is a copy and paste on how maragrine is made:
How is margarine made: Step 1
Margarine makers start with cheap. poor quality vegetable oils, such as corn, cottonseed, soybeans, safflower seeds and canola.
These oils have already turned rancid from being extracted from oil seeds using high temperature and high pressure. Rancid oils are loaded with free radicals that react easily with other molecules, causing cell damage, premature aging and a host of other problems.
The last bit of oil is removed with hexane, a solvent known to cause cancer. Although this hexane subsequent removed, traces of it are inevitably left behind.
How is margarine made: Step 2
The raw oils for making margarine are steam cleaned. This destroys all the vitamins and antioxidants.
However, the residues of pesticides and solvents – that is, hexane – remain.
How is margarine made: Step 3
The oils are mixed with finely ground nickel, a highly toxic substance that serves as a catalyst for the chemical reaction during the hydrogenation process.
Other catalysts may be used, but these, too, are highly toxic.
How is margarine made: Step 4
The oils are then put under high temperature and pressure in a reactor.
Hydrogen gas is introduced. The high temperature and pressure, together with the presence of nickel catalyst, causes hydrogen atoms to be forced into the oil molecules.
If the oil is partially hydrogenated, it turns from liquid into a semi-solid.
Trans fats are formed during partial hydrogenation. These are fat molecules that have been twisted out of shape. In liquid oils, the molecules are bent, with the hydrogen atoms on opposite sides of each other.
During partial hydrogenation, the molecules are somewhat straightened and now all the hydrogen molecules are on the same side.
If the oil is fully hydrogenated, it turns into a hard solid that cannot be eaten. It no longer contains trans fats because the "out of shape” oil molecules have all been broken up to form straight chains. But this does not mean they have become healthy again because of all the unnatural steps above.
How is margarine made: Step 5
What comes out of the partial hydrogenation process is a smelly, lumpy, grey grease.
To remove the lumps, emulsifiers – which are like soaps – are mixed in.
How is margarine made: Step 6
The oil is steam cleaned (again!) to remove the odor of chemicals. This step is called deodorization and it again involves high temperature and high pressure.
How is margarine made: Step 7
The oil is then bleached to get rid of the grey color.
How is margarine made: Step 8
Synthetic vitamins and artificial flavors are mixed in.
A natural yellow color is added to margarine, as synthetic coloring is not allowed!
In fact, early last century, all coloring was not allowed and margarine was white. This was to protect consumers so that they do not get butter and margarine mixed up.
How is margarine made: Step 9
Finally, the margarine is promoted to the public as a health food – with the full endorsement of many scientists, doctors, nutritionists and health authorities.
HOW BUTTER IS MADE:
Step 1 :Fresh milk from dairy farms is collected and brought to the creamery.
Step 2 : The cream is then separated from the fresh whole milk using centrifugal force. It is then pasteurized by heating it rapidly to a high temperature to eliminate potential disease-causing bacteria and help the butter stay fresh longer.
Step 3 : The cream is beaten vigorously in a churning cylinder until it thickens naturally into butter.
