Let's break this down like the digestive system! Detoxes tell us on our diet is filled with "toxins" and "chemicals," that need to be cleaned out. Their solution is to eat raw things, or only drink juice, or whatever… Detoxing is a huge industry that has been completely debunked by medical science, but that doesn't stop us doing it. If you are a drug addict, medical science can help clear your system with a detox, but if not -- buying dime-store online direct-to-consumer health fad detox is not going to do anything helpful. Pills and potions to improve the body have been sold for centuries; and every time science looks into it, it's obvious they're selling snake oil. The human body is an incredible thing -- it can take in any number of edible, drinkable and breathable things which are low-level poisons, and process them. You're probably thinking sugar! alcohol! fast food! But, oxygen, salt, and water are poisons! In high enough quantities, each of those can kill. It's all in the dosage. Everything in moderation, is a great way to look at it. For example, alcohol got its moniker as a poison from the Women's Christian Temperance Union, The Anti-Saloon League and the KKK to get people to stop consuming. Sure, in massive quantities alcohol will poison us, but so will salt or oxygen! Plus, popular "detox" foods like tomatoes and broccoli contain cyanide! And drinking nothing but fructose -- the sugar which makes fruit juice sweet -- does not go over well in humans. In reality, the human body comes with structures designed specifically to clean and filter the blood and digestive systems -- the liver and the kidneys. They do a great job keeping us clean. When we consume anything, the kidneys and liver filter out any "toxins" and send them out of the body as waste. *hands* done. A "detox diet" doesn't help the kidneys do this job any better. According to the Guardian and Harvard Medical School, detox kits are often designed to make you FEEL like you're getting something for your money, even if you're not. For example, there are no little bits of poop stuck in your colon that need to be cleansed, but some colon-cleansing tablets claim to have a polymerising agent that makes your poop stick together in a single piece; so you can then admire it and feel accomplished-- actually, that sounds pretty awesome. BUT IT'S NOT HEALTHIER. Even though the detoxing itself isn't doing anything helpful, the act often has people reporting they feel healthier or have more energy, or even have weight loss! All these things are possible, some might be a placebo… But in the end, it could also be down to the highly restrictive forms of many of these diets. Intermittent fasting has shown some benefits… and if you're restricting nutrients you're essentially fasting. During a fast, your metabolism drops, and your body puts more resources into your brain power to help you find food. In modern society that means more energy flow for your neurons! The reason people keep doing it is a mystery, maybe it's because we want to believe we have control over our bodies, or because we feel like we have to make up for eating badly, or because we hear about pollution and toxins in our environment, or because taking a pill seems easier than exercise… or something else… Who knows. The best way to "detox" your body, is not to drink only juice for a week, that's for SURE; but rather to eat healthily, exercise outside.
