Thank you for your replies. I have since decided to not bother with cleansing diets, as I eat a healthy and balanced diet anyways with lots of fiber, vegetables/fruit, --no more apple cider vinegar, legumes, fish, lean and organically raised meats, lots of water, avoiding dairy and soy, and so on.
Having been told that that's really all a cleansing diet is (adding more types of food to your diet, eliminating others, and/or fasting, or some combination of all three), I realize that I really don't need to do one. My diet is more or less fine. I discovered that I was suffering from a minor vitamin A deficiency (which I would not have expected because I get plenty of beta-carotene in my diet). Since supplementing it (and I plan to get mostly natural food sources of it soon, so I will not have to supplement it), the issues that made me want to begin a cleansing diet have diminished. I think I will continue on my merry way and hopefully my ailments will soon disappear entirely. Thank you though, for replying and offering insight.
A cleansing diet is different from taking a supplement, which is what you're doing by drinking apple cider vinegar. People have claimed all kinds of benefits from organic apple cider vinegar with the mother included in the product; the ultimate believer that this cured everything is Dr. Bragg, who probably isn't actually a doctor, but who knows? It does do some great things for people, and harmful things to others; it depends on how people react to acidity. But it isn't a cleansing "diet." A cleansing diet would be rearranging your entire diet, for a short time or forever, to emphasize cleansing toxins out of your colon, liver, and other organs. The reason you read about fasting a lot is that it's the best cleansing diet there is -- you take in no toxins while your body has the opportunity to clean itself out in the meantime. How long to fast is controversial, but when first starting out it's usually recommended to do one day, then move on later to two, etc. The type of diet would depend on what part of your body you're trying to cleanse. If it's your liver, you're most concerned with fatty foods. If it's your intestinal tract, you're most concerned with adding in foods that clean the colon such as fiber while eliminating those that "stick," such as too much animal products or foods that contain toxic additives. If it's your pancreas, you avoid foods that easily convert to sugar. If it's your joints, you add in anti-inflammatory foods and eliminate pro-inflammatory foods. That's cleansing dieting.
Search youtube: Detox Retreat Success Stories. Results speak for themselves. I was glued to my TV for 5 hours straight watching back to back episodes of the popular UK show "Spa of Embarrassing Illnesses" only to find Austar (Australian paid TV) didn't air the final episode! Grrrr lol.
