Both high cholesterol and high blood pressure have nothing to do with what you eat. The "eating too much cholesterol is bad" claim is a myth, as is "too much salt causes high blood pressure".
If the medical profession truly understood how the body works, they wouldn't be so "prescription-happy". Their claim of getting too much salt from eating processed food is wrong to the point of being a fraud.
As they already know, you ingest salt through processed food as well as using it as a flavor enhancer. But the body is designed to take care of itself - it takes what it needs and discards what it doesn't need since there are no storage compartments to save nutrients.
The one thing the body can't do is obtain sufficient water from food - the average adult loses around 2 quarts of water per day, and the body can't get all of this from food. You have to actually physically drink water.
When you don't, then the body starts holding onto salt since salt retains water. This is the only way it has to prevent cell damage when you won't drink the water you should.
Thus, the "excessive salt" that doctors associate with high blood pressure is the result of chronic dehydration. Another way of understanding this is when doctors advise to stay away from salt and then write a prescription for high blood pressure. If salt is what causes high blood pressure and you follow the advice to avoid salt then there should be no need for the medication. If the cause of a health problem is taken away, the problem will resolve itself.
When they tell you to avoid salt, they never seem to mention "drink more water" - peculiar.
Likewise, high cholesterol is an adaption by the body to dehydration.
Blood is 94% water. When you get dehydrated, it loses 8% of its water volume, causing it to thicken. The metabolic waste contained in the blood becomes concentrated and turns acidic. As this acidic blood gets forced through the arteries under a shearing pressure it damages the tissues.
If left unchecked, this damage can peel off and become embolisms that travel through the bloodstream to the brain or some other main organ and cause a stroke or death or other serious problem.
Cholesterol is designed to cover the damaged tissues like a waterproof bandage until they can be repaired.
Unfortunately, this is where the medical profession steps in and starts writing prescriptions to lower the cholesterol. This exposes the damaged tissues to the same environment that caused the problem in the first place, which triggers the formation of more cholesterol. It becomes an endless cycle with the pharmaceutical companies coming out on top.
Another problem with this "treatment" is that when the damaged tissues are constantly being exposed to the acidic blood, they develop even more damage. There could come a time when the vessels will give out anyway, and there's no amount of medication that will do any good (I've seen it happen).
The way to fix both problems (as well as prevent or fix many others) is to stay properly hydrated by replacing the 2 quarts of water every day - and don't run from salt.
Water is the most important resource the body needs to live because every function is tied to it. It might surprise many people to know that the next most important resource needed by the body is salt.
By avoiding these two most important nutrients, health problems are inevitable. It's not a matter of "if", but "when".
