Many people consider a cleanse after feeling sluggish, tired, or lacking energy. Poor diet, stress, alcohol, and environmental toxins can all contribute. Supporting your body's natural detoxification processes may help restore balance and overall wellness. However, successful detoxification requires more than following the latest trend. Detoxes and diets are not the same. Some cleansing programs can place unnecessary stress on the body and may do more harm than good. Understanding how your body's natural detoxification systems work help you make informed choices. The liver, kidneys, digestive tract, skin, and lungs already remove waste efficiently. Healthy habits and targeted nutrition can support these processes. Before starting any cleanse, learn which approaches are evidence-informed and which to avoid. These detoxification tips will help you support your body's natural detoxification safely and effectively.
How Does a Detox Work?
A detox, short for detoxification, is the body's natural, ongoing process of neutralizing or eliminating toxins from the body. What are toxins? This can be anything that can potentially harm body tissue – think of the process that leads to ammonia, or even man-made toxins that are floating around in the environment that we ingest. Together, our liver, kidneys, intestines, lungs, skin, blood and lymphatic systems work to ensure toxins are transformed to less harmful compounds and disposed of from our body, a detox simply helps this process along. Did you know that the average American has over 90 toxic chemicals in their body? While this stat is scary, Dr. Oz only recommends doing a cleanse 3-4 times a year, at most.
What is a Detox?
Let's define detoxification before exploring different approaches. Many detox programs exist, but this article focuses on a specific method. A detox diet typically lasts at least two to three weeks. It limits foods and drinks that burden the body's natural detoxification systems. It may also include herbs, vitamins, minerals, and nutrients that support the liver, kidneys, and colon. This approach does not include calorie-restricted plans, juice cleanses, or harsh laxatives. Detox foods and supplements do not directly remove toxins. Instead, they support the organs that naturally process and eliminate waste. Strong detoxification depends on healthy liver, kidney, and digestive function. When done correctly, a detox may improve liver function, digestion, elimination, skin clarity, bloating, energy, mood, mental clarity, and healthy weight management.
What Are The Main Detoxification Organs?
Everything that we consume, including food, medication, drinks, and supplements, is filtered through our liver, making it the most important organ in detoxification. Other organs that play important roles in the detoxification process are the lungs, gastrointestinal tract, kidneys, and skin. Since everything is filtered through the liver, it can get sluggish over time from all of the processed, refined and fast food chemicals we consume. In fact, alcohol, refined sugar, coffee, processed/pre-made food and fast foods are included as restricted foods when doing a detox.
Detoxification Tips: Herbs and Nutrients
Herbs such as milk thistle, dandelion, globe artichoke, and curcumin are important for liver support, as are lipotropic factors, choline, inositol, and methionine. Vitamins C, E, and a full range of B’s, as well as minerals such as magnesium, selenium, and molybdenum, are also vitally important for the detoxification process. A number of amino acids (taurine, glycine, glutamic acid), along with CoQ10, and NAC (N-Acetyl Cysteine), are also necessary nutrients for detox – your lungs, liver, and kidneys all benefit from these.
What a detox diet consists of:
- Fruits: Apples, bananas, pears, oranges, etc. [fresh, frozen, dried or canned in natural fruit juice]
- Fruit juice: Homemade fresh fruit juices or smoothies [not sweetened]
- Vegetables: Almost any vegetable: carrots, turnips, sprouts, cabbage, onions, peppers, sweet corn, mushrooms, broccoli, cauliflower, salad, etc. [fresh or frozen]
- Beans and lentils: Any beans: haricot, cannelloni, red kidney, black eye, red lentils, green lentils, etc [fresh, dried or canned in water]
- Starches: Potatoes [all types], brown rice, rice noodles, etc.
- Fresh fish: Any fresh fish: cod, salmon, lobster, plaice, mackerel, crab, trout, haddock, tuna, Dover sole, red mullet, prawns, etc
- Unsalted nuts: Brazil, cashew, hazelnuts, peanuts, almonds, pecans, pine nuts, macadamia, walnuts, pistachio, etc
- Live natural yogurt
- Extras: Garlic, ginger and fresh herbs, honey, etc
- Drink: Tap or mineral water [at least 2 litres a day] + herbal/fruit teas
Avoid eating:
- Meats: Chicken, turkey, Red meat, and meat products such as burgers, sausages, etc
- Milk and milk products, such as cheese, cream, and butter
- Eggs
- Breads: Anything that contains wheat, etc
- Salted snacks, salted nuts
- Refined Sugars: Sweets, jam, chocolate, sugar, etc
- Alcohol
- Coffee, tea
- Fizzy drinks
- Squashes: all types
- Processed foods
- Sauces: salad dressing, pickles, mayonnaise, etc.

Detoxification Tips: Things to Avoid
The diets in the following list have the potential to be harmful and hard on the body. As Dr. Oz exclaims, downsides to popular detoxes can rob the body of important nutrients, place your body in starvation mode and in turn, actually slow down your metabolism. These types of detoxes are typically, if anything, more taxing on our organs and can create dehydration, fatigue, dizziness and/or nausea.
- Avoid 2-3 day detox kits (they tend to be very harsh as they are trying to speed up a process that in no way can, or should happen this quickly.). These short detox diets also tend to be very restrictive, which can have consequences for those with blood sugar issues, blood pressure issues, or immune deficiencies, to name a few.
- Avoid detoxes that use harsh/strong laxatives, and a lot of them, to increase elimination of waste. These can be very inflammatory to the bowel, and for those with inflammatory bowel issues, will surely cause a flare-up. They can also cause cramping, diarrhea, nausea, and dehydration, to name a few side effects.
- Avoid calorie-restricted detoxes that last more than 24 hours. Juice diets have their place, but need to be conducted under the strict supervision of a qualified healthcare practitioner, and again, are not for everyone.
Be cautious when doing these, or any detox, in the heart of the summer or winter. Especially in the winter, when our body is already overwhelmed with cold and flu viruses, and other infection, a detox can further compromise or weaken your immune defences. You should never start a detox when you have an infection.
Other helpful hints
Another ‘must’ with any detox is increasing water consumption, along with fibre. This gently supports the bowel in its job of eliminating all the toxins filtered by the liver, and helps to decrease any side effects. Exercise can also help to support the detoxification process and elimination of toxins through the skin (sweat). So get moving!
How Will A Detox Make Me Feel?
The detox that we are talking about here will have significantly fewer side effects than many of the ‘unhealthier’ detox options. That being said, headaches during detoxification are very common, as are acne flare-ups or skin exacerbation. Generally, the first week of a detox can cause individuals to feel a little more lethargic than usual. Listen to your body and be gentle with it. Go to bed early if you are tired, and don't overdo it with exercise if your body is saying no. By the end of the second week, most people feel significantly better than they did before they started.
We advise you to seek the advice of a Naturopathic doctor before starting any detox regime – they can tailor the detox to your individual needs, and monitor your progress throughout.




I do a detox annually, to ensure everything is cleaned out and working well.

Great information about detoxing. I've never done one before.
Great information about detoxing, I haven't done one but have been thinking about trying. Excellent info for a newbie like me!
I like the advice in this article that recommends a safe way to detox. Eat healthy, exercise, get rest, add in beneficial supplements to support your detox organs. I like the advice not to detox in the hottest or coldest parts of the year when your body is already working harder.
Hello Wendy,
Yes, fad detox's aren't the healthiest way to go about it. We wanted to educate on how to cleanse in a healthy way. Milk Thistle is a great supplement to support detoxification and an overall cleanse.
Stay healthy & well
A good article on how to gradually detox the body. The diet restrictions are pretty extensive. I find it is usually enough to increase fruit and vegetables and eliminate caffeine, sugar, wheat, soy, dairy and red meat. Never heard of eliminating all types of squashes before. I find it also helpful to add a small amount of mineral powder (no sugar added electrolytes) and acacia powder (clear fibre) to all the extra water I drink. A bit of gentle dry body brushing also helps to make sure the lymph system is draining well.

Great article. I was happy to see exercise included in your "helpful hints" With so many toxins are in our food, but also in the air we breathe, the water we drink, products we apply directly to our skin, hair, and even fingernails and eyelashes detoxing is so important. Although some of these toxins will pass through us, but some build up in our organs, causing them to not function effectively. A big mistake I made when I first tried detoxing was not opening my channels of elimination first. I had major detox reactions because I had stirred up all of my toxins, but I wasn't able to effectively eliminate them. After consulting with a Naturopath, I worked on a program that opened up my organs (bowels, liver and gallbladder, kidneys, and skin) for the excretion or elimination of toxins. This made subsequent detox cleanses much more manageable. A few things that really helped me were sauna, bouncing on a trampoline for my lymph system, and as you mentioned exercise, diet, herbs and supplements to help with parasites.
Hello Ryan,
We're happy you enjoyed our Detox 101 article and thank you for sharing your tips and experience. Indeed, your body must be able to release the toxins from a cleanse in order to be effective. We are exposed to toxins daily; therefore daily detoxing activities such as exercise, taking herbs and using a sauna are great ways to micro-detox daily.
Stay healthy & well!
Loved this article! Fabulous information that covered all aspects of detoxification. So important to get this information out to those whom might shy away from cleansing. It offers so many benefits and would be an asset to anyone's health care regime.

Detoxing is something not to be to avoided or brushed off. The body is so full of microplastics and other dodgy ingredients in this North American diet, it's really dangerous the stuff that's out there presented safe for sale when really it's not. Detox combined with fasting is really good. I sometimes do a 23 hour fast, where i only eat for 1 hour per day, and it actually works/ The body doesn't need as much food as we think it uses up fat and turns it into energy which is a good way to lose your fat.

I like your tips on things to avoid. For example, 2-3 day short detox diets also tend to be very restrictive, and though brief fasts or fasting like diets can have metabolic benefits, these need to be underwent with caution and doctor consultation for those with blood sugar or blood pressure issues and other health conditions. Also, excess laxatives can have very bad effects on gut health, as you mention, and also can create dependancy if used in excess which creatres a very difficult situation.
Finally, your note on restrictive detoxes in the winter possibly making it even harder for the body to defend against winter immune assaults is a good one. Thank you for your sane and wise detox cautions!
