Introduction
Detoxing has become a popular trend in recent years, with many people turning to “detoxing foods” to help flush out toxins from their bodies. But is this really a thing? Can certain foods really help your body to detox? In this article, we’ll take a look at the science behind detoxing and how your body actually flushes toxins. We’ll also explore the potential benefits of eating certain foods to help your body detox. By the end, you’ll have a better understanding of how your body works to flush out toxins and whether or not “detoxing foods” are a real thing.
Are ‘Detoxing Foods’ a Real Thing? How Your Body Actually Flushes Toxins
The idea of “detoxing” has become increasingly popular in recent years, with many people turning to special diets and supplements to help rid their bodies of toxins. But is there any truth to the idea of “detoxing”? Can certain foods really help flush toxins from your body?
The answer is yes – but it’s important to understand how your body naturally detoxifies itself. Your body is equipped with a number of organs and systems that work together to filter out and eliminate toxins. The liver, kidneys, lungs, and skin are all involved in the process of detoxification.
The liver is the main organ responsible for detoxification. It filters out toxins from the blood and breaks them down into smaller molecules that can be eliminated from the body. The kidneys also play an important role in detoxification, as they filter out waste products from the blood and excrete them in the form of urine.
Your lungs also help to detoxify your body by eliminating toxins in the form of carbon dioxide. The skin is also involved in the process, as it helps to eliminate toxins through sweat.
In addition to these natural detoxification processes, there are certain foods that can help to support your body’s detoxification system. Foods that are high in antioxidants, such as fruits and vegetables, can help to neutralize toxins and protect your cells from damage. Foods that are high in fiber, such as whole grains, can help to flush toxins out of your body. And foods that are high in essential fatty acids, such as fish and nuts, can help to support your liver’s detoxification process.
So while there is no one-size-fits-all “detox” diet, there are certain foods that can help to support your body’s natural detoxification processes. Eating a balanced diet that includes plenty of fruits and vegetables, whole grains, and healthy fats can help to keep your body healthy and functioning optimally.
“Detoxing” has become a trendy word in the wellness space. As a potential solution for people who have been eating too much sugar, have completely given up on their diet for a while, or who simply want to cleanse their bodies of whatever they consider to be a toxin, detoxing foods and diets are certainly having a moment.
But are there really foods that rid the body from toxins, or is this just one more bogus claim made at the hands of the wellness industry?
How your body rids itself from toxins
Before we dig into whether eating certain foods can truly detox the body, we first need to have an understanding of how the body works when toxins are in the body in the first place.
The word “toxin” has different meanings depending on who you ask. In conventional medicine, the term generally refers to drugs and alcohol, and detoxing means getting a person to stop taking these substances and ridding the body of them as well. But in other circles, toxins refer to pollutants, heavy metals, sugar, and other components that enter our bodies.
The human body has a highly sophisticated mechanisms for eliminating toxins. The liver, kidneys, gastrointestinal system, skin and lungs all play a role in the excretion of unwanted substances. The pathways used for detoxification depend on the particular chemical, although they include conversion to a less toxic form, metabolism to produce a water-soluble form of the toxin that can be urinated out of the body, conjugation to allow for the toxin to be released via a bowel movement, and the ability of the body to bind heavy metals.
So, if you have functioning organs, your body is already working to rid the body of what some people deem to be “toxins.” (Although, they aren’t harmful to our bodies unless we take in certain large quantities. Remember—it’s the dose makes the poison).
“These chemical reactions that help the body ‘detoxify’ are heavily nutrient-dependent and rely on nutrients including B2, B3, B6, B12, and folate as cofactors,” Melissa Azzaro, RDN, LD, a registered dietitian and podcast host at Hormonally Yours, explains. She added that antioxidants, magnesium, choline, protein and water can also play positive roles.
However, certain pollutants like DDT and metals like lead are not easily removed from the body and can take years to break down. So, no matter how healthy and functioning your body is, these items can remain in your system for many years, regardless of what you eat or do to combat this.
Can foods be detoxing?
There is currently no evidence to support the use of most commercial detox diets for removing toxic substances from the body. The main health risks of detox diets relate to severe energy restriction and nutritional inadequacy. Plus, they can be stressful to follow, and may result in feelings of deprivation—ultimately opening the door to overeating once the “detox diet” is complete.
Detox dieters are also at risk of overdosing on supplements, laxatives, diuretics or even water. One example of this is a 19-year-old man who developed serotonin syndrome after following a detox protocol he found online, with the aim of ridding his body from MDMA.
However, there are some studies suggesting that certain nutritional components may have detoxification properties. For example, there is evidence that coriander, malic acid (found in grapes and wine), citric acid (found in citrus fruits), succinic acid (found in apples and blueberries), citrus pectin (found in the peel and pulp of citrus fruits) and chlorella (a type of green algae) exhibit natural chelating properties, suggesting that they may be useful for the elimination of certain toxic metals. Although some of these interventions need well-designed human studies before a firm recommendation can be established.
Selenium supplementation has been shown to reduce the toxic effects of mercury in mammals, birds, and fish. And one study of long-term mercury exposed individuals in China found that three months of selenium supplementation almost tripled the urinary excretion of mercury, suggesting that this intervention helped the body rid itself, or “detox,” from this metal.
One noteworthy study reported that consumption of tropical fruit could reduce mercury levels as a result from eating fish in the Brazilian Amazon. This study showed that for the same levels of fish consumption, eating tropical fruit was associated with a lower level of mercury in the hair, suggesting that the body has similar lower levels as well.
Azzaro adds that cruciferous vegetables, like cabbage, brussels sprouts, and our beloved cauliflower, help support phase 1 detoxification in the liver. Phase 1 detoxification is the first step in a natural process in which the liver uses a pathway to change a toxic substance, like a drug, into a less toxic substance that is easier for the body to excrete. Azzaro also claims that green tea and turmeric may offer support for the body’s natural ability to “detox,” as well.
Eating habits that support detoxification
When focusing on freeing the body from toxins, it is important to keep in mind that it is nearly impossible to be toxin-free, thanks to the world that we live in. Between the mercury found in the oceans, the pollution that is in our atmosphere, and the medications many of us rely on to keep our bodies functioning properly, toxins are going to exist in our bodies no matter which diet we follow.
To reduce our body’s toxin levels, the best thing to do is try and limit your exposure to these items in the first place. Opt for lower mercury fish when you have a seafood meal, wash your produce well to remove any pesticides, and limit or avoid alcohol consumption.
“The bottom line is that eating a nutrient-dense diet high in antioxidant-rich fruits, vegetables, and other foods like green tea and turmeric may help support our liver to do its job more efficiently, help your body bind certain metals, or perform other processes that help our bodies rid themselves of toxins,” Azzaro shared. She reiterates that while these foods won’t “detox” you directly, they can help your body perform its job efficiently to rid itself of components that aren’t benefiting your health.
So, if you want to detox and stick to a remedy that has evidence backing it, skip the expensive “detox cleanses” that may be low in calories, protein, and other important nutrients. Instead, lean on foods that may help your body do its detoxing job—like cauliflower, blueberries, citrus, and broccoli—while avoiding exposure to metals, alcohol, pesticides, and other potentially harmful compounds. Also, drink adequate water to encourage the elimination process, since our bodies rid itself of these compounds via our urine, sweat, and stool. Additionally, limit ultra-processed foods in your diet.
Taking these steps will be a more sustainable way to support your natural detoxification process with very little risk. And it will be a lot more economical than following that trendy detox challenge you found online, too.
