Apple Cider vinegar is an acid . Doesn’t many Cancers like an acidic body to live well within ? Our water here at home is slightly acidic already and we treat it so the Ph rises above 7.5 so I’ll leave the vinegars alone .

I am very healthy and fairly old. Keeping your weight down is
one of the most important things you can do for your health.
I am 73 and have been on diets since I was 15. I have always plateaued and stopped losing weight, , , until doing intermittent fasting and Keto simultaneously. I am now down (with ease) to the lowest weight I have been in 29 years. The belly fat I have had since I was in my 40s, is finally disappearing.

Anyone that ‘knocks’ something without knowledge of it, is
simply STUPID. I have never taken ‘fad’ supplements or done
‘fad’ diets Just sensible food restriction and exercise.

I feel great and look great. Now if you will excuse me, I have to
go outside, play with my 2 terriers, and work on my 50 rose
bushes. I hope you all will be as healthy as I am at this age.

Jesus didn’t push fish, wine, and red meat on anyone. If you want to eat/ not eat it, then you have free will. But don’t blame Jesus for this.

It works for me. Keeps you feeling healthy. It also keeps your teeth white, just add water with it before you rinse your mouth out with it. Gets rid of excess water weight too. I drink two cap fulls in a glass of bottled water before going to bed at night.

Sipping gently with a straw keeps most of the vinegar off your teeth.

Have tried Apple cider for over a year now, every morning in v-8 juice . No noticible results, except I don’t like the v-8 juice unless it has apple cider vinegar in it.

I tried it and it didn’t work.

Firstly, I enjoyed reading this newsletter. You are a good writer not too technical, practical with a twist of wisdom. I understand that Apple cider vinegar is a probiotic though acidic going down once it gets digested it releases basic properties. I use a table spoon everyday and I understand that a good probiotic pill may contain as much as 40 billion beneficial bacteria, fermented foods and beverages contain way more and cheaper. I can also attest to its anti-inflammatory and pain benefit. I suffered at one time from severe arthritic joint pain in my little finger for about 6 months before doing something about it. I was given Celebrex for it and received some temporary relief that lasted about 30 mins. I heard about organic apple cider vinegar and took 2 table spoons at a time which gave me more pain relief for about the same amount time. Eventually I realized that MSG intolerance was the cause of the pain and inflammation and could stop taking apple cider vinegar every few hours which did cause me some stomach upset in that quantity.

“An apple a day keeps the doctor away”!


But that was before they started spraying them with deadly insecticides.

Salmon is good for you!

Yeah! Wild salmon – NOT farmed salmon.

Veggies are good for you!

Yeah! Organic grown veggies — NOT insecticide drenched veggies.

Do YOU get my drift?

Jesus is to blame for GOUT!

One of the huge credibility gaps between science and personal experience is vividly alit in this item. Science can’t find how something works; therefore it doesn’t work. Can’t find God? No problem; There is no God. Can’t find a numerical rhythm in PI? Again, no problem there isn’t any. Actually there really is.
So we move into meds that work or not. Even though they’ll offer you a placebo. So what’s wrong with belief? We know a person can affect their health simply by changing perspectives.
I do have a bone with science; even my own biology. Giving up the hunt is counter science. If you can’t find it, at least find out why not. After centuries of medicine we just now discover a new organ? Really? Is that because of scientific dogma? If science is so precise, why are so many discoveries accidental?
Science does itself a disservice by spouting off and trying to convince people of things. Most believe GMO’s are bad and science will tell us one way or the other depending of the nation we ask. Depending on the death, sickness, environmental destruction, and other things of concern experienced in each of those nations. Our nation is truth challenged.

I have taken apple cider tablets with water for years to relieve painful cramps. It works like magic but I have never seen this remedy anywhere in the media or in the medical literature.

At the point where you wrote ‘Apple cider vinegar comes from apples that have been crushed, distilled, and then fermented’, I began to seriously doubt your knowledge of the subject.
There is no distillation involved in the production of ACV. The apples are crushed and the juice extracted, then the juice is fermented (by yeast) to turn the sugar to alcohol. A secondary bacterial fermentation by acetobacter then turns the alcohol into acetic acid. The acidity of the vinegar is a mixture of this acetic acid and the naturally occurring malic acid from the apple juice.

Interesting re tooth enamel but I have never heard it recommended for weight loss but for arthritis and general health by keeping your gut healthy. All read that farmers in Vermont discovered it was excellent for cows that weren’t calving. (I think we are pretty safe!

I used Apple cider vinegar in my diet mostly after consuming high fat intake calories. It help keep the weight off and I’ve lost weight. It works for me.

I ate sauerkraut salad made with apple cider vinegar almost everyday for about 2 months, and it damaged my tooth enamel despite rinsing my mouth after eating it. I’m currently trying to remineralize a tooth, which my dentist wanted to fill. Just 2 weeks after I stopped consuming ACV and using products to remineralize, my teeth have improved. Dentist has pictures. Avoiding ACV like the plague.

Disagree. Pair vinegar(s) with the heart-healthy Mediterranean diet/lifestyle…not to forget olive oil, tea, and honey–yes, you can lose unwanted weight–and more! Top experts show how it works!

Disregarding the pros and cons of vinegar for weight loss, I selected the apple cider vinegrette to use on my daily salad lunch because it was sodium free, fat free, and tastes good. Consequently, I eat more of my favorite spinach salads, which is low calorie and good for you. It is beneficial for my heart disease and health. I would contribute the health benefits to the veggies, rather than the vinegar, but hey, anything that makes veggies taste better without adding calories or sodium is not all bad.
Pass the salad please.

I’d like to know about PREbiotic and probiotic. There is a DR Gunter (?)…..saying, a SIDE effect is weight loss.
I wonder what Harvard Health thinks about it?

I tried this for about two weeks and suffered from itchy skin, particularly on my limbs and abdomen. It’s so irritating for your whole body to itch at once! As soon as I stopped taking ACV, the itching subsided drastically. It did cause me to feel fuller and not so hungry. I’ve now replaced it with lemon water. So far, so good.

Is Apple cider vinegar use in treating blocked fallopian tube?

A couple comments… They make apple cider vinegar capsules, which protect your tooth enamel and which don’t have an obnoxious taste.

Apple cider vinegar is great for acid reflux; just take a couple of capsules 10 minutes before eating. The apple cider vinegar closes the valve that protects your throat from stomach acid.
