If you want just one valuable addition to any diet, I recommend Drumstick Tree (Moringa oleifera). Water Thyme (Hydrilla verticillata) is another excellent candidate. Certain of the Brown Seaweeds (actually macro-algae, not plants) would add in Iodine, in which most Americans are deficient.

my BIL has been fighting a skin rash which the docs are throwing things at. I got him the "horse paste" via mail order -- it is a paste with ivermectin at 1.87 percent in a non-reactove carrier -- to apply externally. Used as a rub-on, it seems to be providing relief and some remission. Work in progress....

Ivermectin Horse paste- cheap- rub it on.It has helped me and friends in so, so many ways. A woman I know rubbed it on her pre- cancerous ( Melanoma?) spot, three weeks later- healed.

I would also look into a liver flush which is drinking a tablespoon of epsom salts in warm water and a 1/4 cup of olive oil. Sounds grosser than it is but it will really help to flush things and get it moving. 

There are supplements that directly force defective mitochondria to self-destruct and make new, healthy ones. One such item is urolithin A, available from Celltrient and Timeline Nutrition, in the form called “Mitopure.”

The senolytics mentioned above generally seek to kill the whole cell, rather than just the mitochondria.

Drinking the Lemon Juice Really works and it's natural, 8 oz 3 times a day followed by lots of water the pain has let up some.

Or you could just take 1000-2000mg of Fish Oil (especially EPA) daily. I dropped my tryglicerides from 240 to under 140 in less than 3 months using this inexpensive OTC suppliment.

ALSO:
I never heard of tricaprin before, but it seems very worth it to examine.

In the meantime, having plenty of Vitamin K2 and Vitamin D will keep calcium out of your arteries, having plenty of anti-oxidants will keep LDLs from oxidizing as much, and having plenty of Omega-9 oils (from EVOO and avocados) will promote overall good heart health - those things, and at least some degree of moderate exercise, getting a reasonable amount of sleep and not smoking or drinking to excess. This isn’t rocket science.

Perhaps vaccination is not the answer. It is, at best, only a stopgap measure at this point. A more personal form of prevention would include changes in diet, adding a zinc compound like zinc gluconate, and a zinc ionophore like Vitamin D3, quercetin, or hydroxychloroquine. In therapeutic level of dosage, the presence of the Zn++ ion stops the replication of the COIVID-19 Wuhan virus in its tracks, and the natural immune factors of the body now respond to this “killed” virus. In effect, your body learns to fight off the virus by being trained to recognize and resist the infection.

Which is what the vaccine was supposed to do.

Turmeric and milk paste to draw out a cyst.

Turmeric for inflammation.

Lemon juice keeps my reflux at bay. An ounce before bed keeps me from waking up choking on reflux.

Colloidal Silver is good for infections.

I do original Coca Cola for small kidney stones. Drink 6 cans in two hours. Follow with a can of asparagus. Relief has been immediate.

Daily D3 to prevent flu and colds

Several in my family have used colloidal silver for kidney infections to good effect. It is a general antibiotic that germs don’t get inured to.
Mange and dandruff — Mix 50% borax and 50% apple cider vinegar. Shake it up, and immediately apply to fur/hair before it quickly solidifies. Apply generously to hair and leave it on for a few minutes. To keep it from solidifying quickly so it is easier to use, you can do a little more vinegar, such as 25% borax and 75% apple cider vinegar. This will also remove build up on your hair from shampoos and conditioners.

Apple cider vinegar for yeast infections

I have heard from someone who tried it that baking soda mixed with olive oil and applied to a precancerous skin lesion will get rid of it. Cancer cannot survive in the presence of baking soda.
