I’m A Doctor — Focusing Too Much On Your Protein Intake Is Putting Your Health At Risk

In his latest newsletter, NHS Surgeon and TikTok creator Dr Karan Rajan reveals that back in 2018, he was doing pretty significant damage to his gut health without even realising it.

He says: “My Indian ancestors were spiritually shaking their heads at me, because despite coming from a lineage of fibre-laden dal, lentils, and spice-rich cuisine, my diet at the time contained about as much fibre as a wet paper towel.

“You could almost hear the garam masala, coriander, and cumin seeds collectively sighing in disappointment every time I ate yet another low-fibre, protein-heavy meal.”

However, his gut health seemed fine. He was regularly passing stools, still very active and, in his words, “Nothing about my daily life screamed -you are a fibre-deficient failure.”

However, his blood tests said otherwise

While the routine blood tests he undertook didn’t suggest that a heart attack was imminent, Dr Rajan did experience a bit of a shock to the system when they revealed that his health wasn’t quite where it should be.

He explains: “let’s just say certain fractions of my cholesterol were slightly higher than they should have been. My triglycerides were creeping up, whispering ominous things about my future and the overall pattern wasn’t what you’d expect from a “healthy” young person.”

Initially, it didn’t make sense to the doctor. He didn’t eat fast food, he regularly exercised and his diet appeared to be overall pretty good.

Then, he explained, “it hit me…I had completely neglected one of the most powerful metabolic regulators: fibre.”

Fibre: essential for more than just bowel movements

Dr Rajan says: “Most people think of fibre as nature’s plumbing assistant; helpful for keeping you regular, preventing constipation, and producing structurally sound poops.

“But fibre is a metabolic heavyweight.”

He explains that some of the benefits of fibre include:

  • Cholesterol regulation: “It reduces cholesterol reabsorption, meaning less circulates in the blood, keeping arteries unclogged”

  • Blood glucose control: ”High-fibre diets have been linked to a reduced risk of type 2 diabetes… and if you already have diabetes, fibre can blunt those glucose swings”

  • Cognitive & neurological benefits: Emerging research suggests fibre indirectly supports brain health by feeding gut bacteria that produce short-chain fatty acids (SCFAs). SCFAs reduce neuroinflammation, improve the gut-brain axis, and may even protect against cognitive decline

  • Microbiome & liver function: ”A fibre-rich diet lowers systemic inflammation, reducing fatty liver disease risk and keeping gut-derived endotoxins from overwhelming the liver”

The UK Government also urges that we should eat more fibre

On their website, The British Nutrition Foundation warns: “Adults in the UK are not consuming enough fibre. On average, we consume about 20g per day rather than the recommended 30g.”

The UK Government also urges that eating more fibre can reduce your risk of bowel cancer, adding: “Fibre is an important part of a healthy diet as it aids digestion, prevents constipation and helps to reduce your risk of bowel cancer. Foods like wholegrain cereals, wholewheat pasta, oats, beans, chickpeas, and lentils are all sources of fibre.”

How to add more fibre to your diet

The NHS recommends the following steps:

  • Choose a higher-fibre breakfast cereal such as plain wholewheat biscuits (like Weetabix) or plain shredded whole grain (like Shredded wheat), or porridge as oats are also a good source of fibre.
  • Go for wholemeal or granary breads, or higher fibre white bread, and choose wholegrains like wholewheat pasta, bulgur wheat or brown rice
  • Go for potatoes with their skins on, such as a baked potato or boiled new potatoes. Find out more about starchy foods and carbohydrates.
  • Add pulses like beans, lentils or chickpeas to stews, curries and salads.
  • Include plenty of vegetables with meals, either as a side dish or added to sauces, stews or curries
  • Have some fresh or dried fruit, or fruit canned in natural juice for dessert. Because dried fruit is sticky, it can increase the risk of tooth decay, so it’s better if it is only eaten as part of a meal, rather than as a between-meal snack
  • For snacks, try fresh fruit, vegetable sticks, rye crackers, oatcakes and unsalted nuts or seeds

I’m A GI Surgeon ― When You Eat Bananas Affects Their Health Benefits

Posted on by

Did you know unripe bananas can have a small laxative effect?

I do, but not because I’m an expert on the fruit. I just really, really like green-tinted bananas ― life’s the best teacher, I suppose.

As bananas ripen, they become sweeter, too. That’s partly why they’re preferred for banana bread.

But according to gastrointestinal (GI) surgeon and author Dr Karan Rajan, there’s more variation in the food’s health benefits than you’d expect.

In a recent TikTok, he shared: “If you’re eating a banana… each stage offers a completely different nutritional profile.”

Which stage of banana ripeness is healthiest?

It depends on what your goals are.

In their green stage, Dr Rajan says, bananas are packed with resistant starches that work as a prebiotic (food for the healthy bacteria in our gut).

A 2021 study found that the resistant starch which is most present in the least ripe bananas can help to improve our microbiome.

Green bananas are lowest in sugar (10g per 100g) and highest in fibre (3.5g per 100g), the doctor continues.

In brown-spotted, overripe bananas, the sugar content nearly doubles to 17g per 100g. That, alongside their higher fibre content, is why less-ripe bananas might be better for those with diabetes.

Barely-ripe bananas have slightly less fibre and slightly more sugar, though as the fruit ages, “you also get more of a potassium boost.”

Fully ripe yellow bananas, meanwhile, are “packed with antioxidants,” the doctor says ― including catechins, which are great for our heart health and reducing inflammation.

It’s also got the highest vitamin C and B5 levels, and because that resistant starch we mentioned earlier has all but gone by the time the banana’s yellow, it;s far easier to digest.

That makes it perfect for a pre-workout snack, Dr Rajan suggests.

Lastly, overripe bananas have more sugar ― good for a quick, if short-term, energy hit ― and contain the least fibre.

It is also, however, “the richest in antioxidants” the fruit will ever be, as the brown spots we associate with older bananas come from those heart-healthy catechins.

How big are the differences really?

The 2021 paper we mentioned earlier said that while the types of fibre, sugar, and starch levels in bananas can change as they ripen, results from controlled studies don’t always match what’s found in store-bought bananas.

That’s partly down to “variables in the supply chain,” they say.

Besides which, all bananas have some health benefits. Turns out the best banana is often the one you like most.

This NHS Doctor’s Sleeping Hack Can Make You Fall Asleep Within Minutes

If you suffer from insomnia or even just have occassional bouts of being unable to sleep, you’ve likely tried every trick in the book.

From sleepy girl mocktails to magnesium supplements, sometimes the sleep just isn’t coming and you’re left wide awake in bed counting down how many hours of sleep you’d get if you fell asleep riiight… now.

It’s unbearable and knowing the health impacts of losing sleep such as mental health problems and even diabetes doesn’t do much to make you feel more rested.

However, according to one NHS surgeon, there is something we don’t do enough and it actually works as a ‘biological power off button’.

How to fall asleep faster, according to a health expert

Dr Karan Rajan, an NHS surgeon, social media creator and all-round health expert revealed that there is a sort of ‘Spotify shuffle’ we can do to help ourselves doze off faster.

In a recent Instagram reel he said: “If you’re struggling to fall asleep, this is the biological equivalent of holding down the power button.

“When you’re in bed, it’s easy to get into repetitive, disrupting thought patterns. This can trigger a stress response which keeps you awake, the more you’re awake, the more unwanted thought patterns you get, meaning less sleep.”

However, he revealed that a sleep hack named ‘cognitive shuffling’ can break this cycle by taking away your active cognitive effort (overthinking.)

Dr Rajan said: It’s the human brain version of pressing shuffle on your mind Spotify playlist.”

How to do cognitive shuffling

First, choose a word. The word that Dr Rajan chose was aptly “bedtime”.

From there, for each letter of that word, think of another word starting with that letter and visualise it.

So, for example, for the letter ‘B’, you could choose words like bear, brace, bones, bench.

Keep doing that until you’re out of words or bored and then move on to the next letter.

Dr Rajan urges that you visualise these words too as it simulates micro-dreams.

He said: “This trick helps to calm racing thoughts, so if your sleep software is malfunctioning, it’s worth giving it a go.”

The Simple Reason Why You’ve Been Storing Your Cheese Wrong

Have you found that no matter how well you seal plastic food bags, cheese always tends to go off inside of them very quickly?

Yes, me too. I find myself reaching for the cheese a couple of days later, only to see that it’s suddenly inedible.

Well, it’s not because we haven’t sealed them effectively, according to one medical expert. It’s much more simple than that and in part comes down to the types of cheese we’re having.

Dr Karan Rajan explained in a recent TikTok video that if you’ve been wrapping your cheese in food bags, you’ve been setting yourself up for failure.

How to properly store cheese

So if, like me, you thought that most foods could be refrigerated in the same way, this will be a cold awakening. (Sorry.)

Dr Rajan explained: “Once you finish gobbling your cheese like a hungry little rat, try and avoid putting your cheese in a plastic bag. Especially softer cheeses which have a higher water content.”

These include Havati, Mozzarella, and Gouda.

He said: “This is because moisture can get trapped in the plastic bag and cover the cheese surface. This provides a breeding ground for bacteria and mould — and not the tasty kind.”

Instead, Dr Rajan recommends using cheese paper, which actually is a thing, yes. Alternatively, parchment paper is a good choice, too.

If you are still keen to use plastic bags, Dr Rajan recommends first wrapping the cheese in wax, parchment or cheese paper before placing it inside of the bag.

Fortunately, harder cheeses like Parmigiano can withstand plastic bags no problem.

He did also point out that you could just eat the food very quickly, ‘for science, of course’ and to reduce food waste.

Of course.

If You’ve Ever Wondered Why You Fart More On Planes, This Is For You

Posted on by

We don’t talk enough about the sensory experiences on flights. The popping ears, the flip of the stomach as take-off happens, the vast array of confined noises all happening at once… it’s a lot.

However, the one sensation that we really don’t talk enough about is just how much more gassy we are when we’re thousands of feet in the air. It’s fine, you don’t have to say it out loud, we’re saying it for you.

There’s something so cruel about experiencing excessive gas when you quite literally can’t escape the situation but it really is normal and if you experience this, you’re not alone.

In fact, according to Dr Karan Rajan, it’s pretty much unavoidable.

Why you need to fart more on planes

In a reel posted on Instagram, the doctor explained that because the cabin pressure decreases which leads to the air inside of your intestines increasing by up to 30%.

Then, since your colon has limited space and can only expand so much, a natural consequence is to release the fumes. While you can try to hold farts in, not only is that going to leave you feeling uncomfortable, it’s also almost impossible on a flight.

This is because the pressure of the gas travelling down will take over the integrity of your anal sphincter, and some stinky fumes will make their way out. Sorry.

If you’ve ever wondered why the food on planes is very carb-heavy, this is why. Low fibre foods are less likely to leave you quite so gassy.

However, Dr Rajan assures, the filters in flight air conditioners are actually charcoal and they can absorb a lot of the smell. If you do worry about farting too much or just have a sensitive stomach, he recommends avoiding high FODMAP foods such as onions, garlic, seeds, and some kinds of breads as well as eating slowly to aid digestion.

Plus, you can take comfort in knowing this can happen to everyone so you won’t be the only gassy passenger.

The 3 Major Reasons Why Women Get Much Worse Healthcare Than Men

Posted on by
Reply

Following a TikTok user pointing out that her partner received more aftercare following his vasectomy than she did after giving birth, Dr Karan Raj stepped in to explain why women are still getting the short straw when it comes to healthcare, and specifically pain relief.

Dr Raj said that this is down to a combination of systemic unconscious bias, a lack of research, as well as a failure to acknowledge biological differences in how women process pain.

All of that has led to pain being dismissed, misdiagnosed or undertreated which can have lethal consequences.

Love. That. For. Us.

Why women’s healthcare still falls behind

The surgeon added that despite advances in healthcare, women are diagnosed ‘significantly’ later across over 700 diseases and in some cases, such as endometriosis, waiting up to 10 years for diagnosis.

Frustratingly, he also revealed that sometimes, women’s pain is wrongly attributed to psycological causes and the word ‘hysteria’ was only removed from the American Psychiatric Association’s DSM classification.

Additionally, women’s health and specifically pain-focused research is less likely to be studied in clinical trials which makes effective treatment difficult to find.

He admitted that to this day, we don’t know how women metabolise and react to various pain medications or how women experience or manifest pain.

Finally, he said that because there are so many knowledge and gender gaps when it comes to women’s pain, “It’s imperative that we treat the pain the patient has, not the pain we think the patient should have.”

How to advocate for yourself at the doctors

According to the period health experts at Clue, these are the best ways to advocate for yourself at a doctor’s appointment:

  • Be prepared and assertive. Write a list of symptoms to discuss with your doctor and on the day, , give the doctor the facts about your symptoms and don’t downplay your symptoms
  • Ask questions. For example, if you don’t feel that your doctor has considered alternatives, simply say, “is there anything else it could be?”
  • Try to not be pressured into treatment that you don’t want to do. It’s normal to need a second opinion and listening to your own thoughts and feelings matters, too
  • Take notes at your appointment to ensure that you remember everything that’s said and can refer back to them in future appointments
