You are right about raw

You are very right about raw.
Raw diet does not warrant being free of parasites.

All animal species have at least 5 - 150 different parasitic animals that can live like parasites on them, and one thing is sure: all animals eat raw food.

Actually, eating raw meat or raw fish is almost sure way to contact parasites, especially if it is wild meat.

Wild animals are loaded with parasites.

It is also true that people who mostly eat processed foods and junk foods may actually lower their immunity, and as result, if they come in contact with parasite eggs, they may get infected.

So, avoiding processed foods and junk foods may help prevent parasite infection, but is is not bullet proof system.

If there was way to eliminate parasite infection, parasites would not exist.

Our main protection from parasites is hygiene. It is not bullet proof.

Food that may carry parasites must be sterilized in some way, if we are to avoid infection.

Another very important way to prevent parasite infection is to have strong stomach. It is not bullet proof.
Strong stomach acids help prevent infection, but some parasites evolved to use It, like Tapeworms and ascaris.
