Why Science Often Gets Food Stories Wrong (And What We Should Do About It)

Food is something we all care about, what we eat, what we avoid, what might help us live longer, or what might make us ill. 

So when headlines scream, "Red meat causes cancer!" or "Wine is good for your heart!" it’s no wonder people sit up and pay attention. But how reliable are these scientific-sounding food stories?

The truth? Science often gets food stories wrong, or, more accurately, the way science is communicated to the public often distorts the reality of what was actually studied. 

Let's take a closer look at why this keeps happening, and how we can all become savvier eaters and readers.

1. Nutrition science is incredibly complex

Unlike something like physics, where experiments can be repeated in tightly controlled lab environments, nutrition research often deals with messy, real-life conditions. People eat a huge variety of foods, in different combinations, in different quantities, with varying genetics, lifestyles, and health conditions.

Trying to isolate the effect of one nutrient—like saturated fat or fibre, often relies on observational studies, which can only show associations, not causation. So, if a study shows that people who eat more processed meat have a higher risk of heart disease, it might not be the meat, it might be that they also smoke more, exercise less, or have other dietary factors at play.

2. The media loves a bold headline

Studies are often misrepresented in the media because nuance doesn’t sell. A story like “Small-scale study suggests possible link between compound X and reduced risk of disease Y, but more research is needed” won’t make the front page. But “CHEESE CURES CANCER” just might.

The result? We’re whiplashed by contradictory stories: one week eggs are bad for you, the next week they're a superfood. It creates public confusion and fuels distrust in science, when in fact, it’s often the journalism that’s the problem—not the science itself.

3. Industry funding and biases can play a role

Sometimes the science is skewed from the beginning. A company funding research into its own product can influence study design, publication, and interpretation of results. That doesn’t mean all industry-funded research is invalid, but it does require a critical eye.

Think of studies funded by soda companies that try to downplay the link between sugar and obesity, or food industry-backed research focusing on exercise rather than diet in tackling weight gain. These subtle shifts in focus can have a massive impact on public perception.

4. Science changes—because that’s how science works

We often forget that science is not a fixed truth—it’s a method. When new studies come out that contradict older ones, that doesn’t mean the whole field is unreliable. It means we’re learning more and refining our understanding. But to the public, it can feel like scientists are constantly changing their minds.

This is especially difficult in food and health reporting, where people understandably want clear, simple answers. Unfortunately, science rarely offers certainty, it offers probability, patterns, and evolving insight.

5. What can we do about it?

Don’t rely solely on headlines. Dig deeper or wait for reviews from trusted health sources like the NHS, the British Dietetic Association, or reputable health journalists.

Beware of “miracle” foods or “evil” ingredients. If something sounds too good or too bad to be true, it probably is.

Understand study types. Randomised controlled trials (RCTs) are stronger than observational studies, but still not perfect. Look for meta-analyses that review many studies on a topic.

Watch out for conflicts of interest. Always ask: who funded the study?

Eat based on overall patterns, not one ingredient. A varied, mostly whole-food, plant-forward diet still holds strong across decades of research.

The relationship between food and health is deeply personal, cultural, and emotional—but it’s also scientific. The problem isn’t with science itself, but how we translate it into public knowledge. If we can learn to question the headlines, understand the limits of research, and think in terms of long-term patterns rather than quick fixes, we’ll all be better off.

So next time you see that catchy article claiming that chocolate, coffee, kale, or ketchup will either kill you or save you, take it with a (moderate) pinch of salt.

Coconut Water and Cancer: Separating Facts from Fiction

In recent years, coconut water has enjoyed a meteoric rise in popularity, touted as a natural superdrink brimming with health benefits. 

From hydrating your body better than water to replenishing electrolytes post-workout, it’s often marketed as a miracle in a bottle.

Among the more controversial and unproven claims is that coconut water can “beat” cancer. But how much of this is rooted in science, and how much is wishful thinking?

Let’s take a closer look.

What Is Coconut Water?

Coconut water is the clear liquid found inside young, green coconuts. It is not the same as coconut milk, which is made by grating the meat of a mature coconut and mixing it with water. Coconut water is naturally low in calories, rich in potassium, and contains small amounts of calcium, magnesium, and phosphorus.

It is often promoted for its:

Hydrating properties

Electrolyte balance

Antioxidant content

Digestive support

The Alleged Anti-Cancer Claims

Online health influencers and some natural health websites have suggested that coconut water has anti-cancer properties. Claims range from it being able to “kill cancer cells” to preventing tumour growth or even curing the disease. These statements are almost always anecdotal, vague, or supported by limited lab-based studies that haven’t been replicated in human trials.

What Does the Science Say?

Let’s be clear: there is no scientific evidence that coconut water can cure or significantly treat cancer in humans.

Some laboratory studies on compounds found in coconuts, not necessarily coconut water, have shown antioxidant and anti-inflammatory properties. For instance:

Certain polyphenols and cytokinins (like kinetin) in coconut water have been studied for their cellular health benefits.

Antioxidants may play a role in reducing oxidative stress, which is linked to chronic diseases, including cancer.

However, these findings are very early-stage and do not support any clinical use of coconut water in cancer therapy.

In fact, cancer is a complex group of diseases, and treatment typically involves combinations of surgery, chemotherapy, radiotherapy, and immunotherapy, none of which can be replaced by a drink, no matter how healthy it may be.

Why Do These Claims Persist?

Anecdotal stories: Personal experiences of people improving their health while drinking coconut water are often shared widely, but correlation does not equal causation.

Desire for natural cures: Many people seek alternatives to conventional cancer treatment due to fear of side effects or mistrust in pharmaceuticals.

Misinformation online: Social media and unregulated wellness blogs are breeding grounds for exaggerated health claims.

The Real Benefits of Coconut Water

While it can’t beat cancer, coconut water can offer real, modest health benefits when consumed in moderation:

Hydration: Its natural electrolytes make it a good option after light exercise or in hot weather.

Low calorie content: A good alternative to sugary fizzy drinks.

Kidney health: Some studies suggest it may help reduce the risk of kidney stones.

Digestive support: Contains enzymes that may help with digestion.

However, it's not a miracle food. For people undergoing cancer treatment, hydration and nutrition are vital—but always best managed with guidance from oncologists and dietitians.

Bottom Line

Coconut water is a healthy, refreshing beverage that may support overall wellness, but the claim that it can "beat cancer" is not backed by credible scientific evidence. 

It's important to be wary of misinformation, especially when it concerns something as serious as cancer. If you or someone you know is undergoing treatment, always consult with medical professionals before considering alternative or complementary therapies.

Enjoy coconut water for what it is, not for what it’s falsely claimed to be.

Could Protein Supplements and Shakes Be Linked to Colon Cancer?

In today’s fast-paced world, many people turn to protein supplements and shakes to help build muscle, aid weight loss, or simply boost their daily nutrition. 

However, as these products have grown in popularity, so too have concerns about their long-term health effects. 

One area receiving increasing attention is the potential link between regular use of protein supplements, particularly certain types, and an increased risk of colon cancer.

Understanding Protein Supplements

Protein supplements come in various forms: whey, casein, soy, pea, and rice protein powders are among the most common. They are heavily marketed to athletes, gym-goers, and those aiming for a high-protein diet. While they can certainly offer convenience and support muscle growth, not all protein supplements are created equal. Some products contain added sugars, artificial sweeteners, preservatives, and even undisclosed ingredients.

The Potential Cancer Connection

Emerging research suggests that diet plays a significant role in colon cancer risk. High intake of processed and red meats has long been associated with increased risk, but now attention is turning to highly processed supplements too. Although protein powders themselves are not meats, they can sometimes mimic the effects of a high-protein, low-fibre diet — a dietary pattern associated with colon issues.

Some key points that scientists are exploring include:

High Protein, Low Fibre Diets: Fibre helps to protect the colon by supporting healthy digestion and feeding beneficial gut bacteria. Diets very high in protein but low in fibre may lead to harmful changes in the gut microbiome, potentially raising colon cancer risk. Many people using shakes may inadvertently reduce their intake of fibre-rich foods.

Processing and Additives: Some protein powders are highly processed and contain additives that could contribute to inflammation or oxidative stress, both of which are linked to cancer development.

Hormonal Effects: Certain animal-based protein powders, like whey and casein, can influence levels of insulin and other growth factors in the body. Elevated levels of insulin-like growth factor-1 (IGF-1) have been associated with a higher risk of several cancers, including colon cancer.

Contaminants: Testing has found that some protein powders contain traces of heavy metals like arsenic, lead, and cadmium, especially products made outside of regulated markets. Long-term exposure to such contaminants can contribute to cancer risk.

What Does the Research Say?

It is important to note that, currently, there is no definitive proof that protein shakes themselves cause colon cancer. Most available studies suggest potential risks based on associated dietary patterns rather than direct causation.

For example, a 2023 review published in Nutrition and Cancer discussed how high-protein, low-fibre diets could alter gut health in ways that might increase the risk of colorectal cancer. Another 2022 study from Cancer Epidemiology hinted at possible risks tied to ultra-processed food consumption overall — which includes many types of ready-to-drink protein shakes.

However, no large, high-quality, long-term studies have yet confirmed a direct link between protein supplements and colon cancer specifically.

How to Protect Your Health

If you use protein supplements regularly but are concerned about potential risks, there are sensible steps you can take:

Prioritise whole foods: Try to get most of your protein from whole food sources like lean meats, beans, lentils, nuts, seeds, eggs, and dairy.

Choose cleaner supplements: Look for third-party tested protein powders without artificial additives, and with minimal processing.

Keep fibre intake high: Even if you’re using shakes, make sure you are also consuming plenty of fruits, vegetables, whole grains, and legumes.

Moderation is key: Occasional use of protein shakes as part of a balanced diet is unlikely to pose significant risks.

Stay informed: As research continues to evolve, staying aware of new findings will help you make the best choices for your health.

Final Thoughts

While the current evidence linking protein supplements and colon cancer remains preliminary, it’s clear that diet quality as a whole plays a vital role in cancer prevention. Relying heavily on processed foods — even protein shakes — at the expense of natural, fibre-rich foods could increase risk over time.

If you’re using protein powders, use them wisely: as a supplement, not a replacement. A balanced diet, rich in fibre and minimally processed foods, remains the best defence against colon cancer and many other chronic diseases.

All foods give you cancer?

If you follow the news it seems that all foods give you cancer and that the incidents of cancer are rapidly growing.

But if we are eating the same foods as we previously did, how come the risk of cancer is now rapidly growing?

Implicated by some campaigners are: Processed meats, tinned foods, fried food, "overcooked" food, eggs, dairy, sugar, artificial sweeteners and alcohol. 

But! Researchers for Cancer Research UK have completely refuted these claims. And casts doubts on certain superfoods as being helpful in warding off cancer.

https://www.cancerresearchuk.org/about-cancer/causes-of-cancer/diet-and-cancer/food-controversies

CRUK says: 

"Eating sugar doesn’t cause cancer."

"Eating burnt food does not cause cancer."

"Artificial sweeteners don’t cause cancer."

"Eating eggs does not cause cancer."

"Eating canned or tinned food does not affect cancer risk."

"Eating soy products does not affect cancer risk, including breast cancer."

Obviously eating a healthy diet is important, but many of the claims by some campaigners should be taken with a healthy pinch of salt. And don't get me started on salt! However, seeing as you asked...
