Are blueberries actually “good for you”?

Yes… but not for the reason most people think.

They’re not just antioxidants.

Blueberries contain compounds like anthocyanins and polyphenols that act more like gene signalling molecules than direct antioxidants.

They help switch on your body’s own antioxidant and detox systems.

Which means the benefit you get depends on your genetics.

Some people may benefit more, especially if they have variants in genes like:

• MnSOD – protects mitochondria from oxidative stress
• NRF2 – regulates hundreds of antioxidant and detox genes
• GSTP1 – supports detoxification pathways

Same food.
Different biological response.

That’s the shift.

It’s not just “is this food healthy?”
It’s “how does my body respond to it?”

Because nutrition is not one-size-fits-all.

Sleep isn’t just “rest”.

It’s biological repair.

Every night, your body is:
• regulating your immune system
• clearing waste from the brain
• rebalancing hormones
• controlling inflammation

And when sleep is poor, that system breaks down.

What the research shows 👇
Even short term sleep restriction can increase CRP (a key marker of inflammation) by 145%.

Worse still?
After “recovery sleep”, it didn’t normalise.
It increased further - up to 231% above baseline.

That’s not a small shift.
That’s a major inflammatory response.

Why does this matter?

Because chronic low grade inflammation sits underneath:
• cardiovascular disease
• insulin resistance
• autoimmune conditions
• mood disorders
• cognitive decline

If your sleep is off, your inflammation rises.
And when inflammation rises, everything becomes harder to regulate.

Sleep is not optional.
It’s foundational.

If you’re trying to improve your health - start there.

Coeliac disease and oats…
Can you have them or not?

There’s a lot of confusion - and a lot of trial and error.

The truth is 👇
It’s not “all coeliacs must avoid oats.”
It’s not “oats are always safe.”

Some people with coeliac disease or gluten intolerance can tolerate certified gluten-free oats.

But there are two key issues:

• Cross-contamination
Oats are often contaminated with wheat, barley and rye.
If it’s not certified gluten-free - avoid it.

• Genetic sensitivity
Some people with the HLA-DQ2.5 variant are more likely to react to avenin (the protein in oats).

For these individuals, oats and oat milk may still trigger symptoms.

This is where genetics matters.

Instead of guessing, eliminating, and reintroducing foods…
You can identify your risk upfront.

And it’s worth knowing - because oats contain beta-glucan, which has real benefits for gut and metabolic health.

So you don’t want to cut them out unless you actually need to.

Stop guessing.
Personalise your approach.

ADHD isn’t just behavioural.
It’s neurochemical.

If you’ve been diagnosed with ADHD - or suspect you have it - one enzyme matters more than most:

COMT

COMT controls how quickly your brain breaks down dopamine, especially in the prefrontal cortex - the area responsible for:

• focus
• motivation
• planning
• impulse control
• emotional regulation

Here’s where it gets interesting 👇

Too little dopamine → poor focus, low drive
Too much dopamine → anxiety, overthinking, irritability

COMT determines how fast dopamine is cleared.

And your genetics influence this directly.

Some people clear dopamine too quickly.
Others hold onto it longer.

Neither is “good” or “bad”.
But it changes how your brain functions under stress, pressure and stimulation.

This is why ADHD treatment isn’t one-size-fits-all.
Different people respond very differently to the same strategies or medications.

The shift is this:

Stop asking
“Why can’t I focus?”

Start asking
“How does my brain regulate dopamine?”

Because once you understand that, you can start to personalise your approach.

Struggling with eczema or ongoing skin issues?

It might not just be “skin deep”.

Research shows that many of the same genetic variants linked to food intolerances are also associated with skin conditions such as:
• eczema
• atopic dermatitis
• dry, sensitive skin
• persistent itching

This is especially important in children.

If your child has eczema, it’s worth considering whether certain foods may be contributing.

The key triggers to investigate:
• gluten
• dairy
• histamine
• egg
• peanuts

The earlier symptoms appear - and the more severe they are - the more important it becomes to identify potential triggers early.

Genetic screening offers a simple and accurate way to understand predispositions to food intolerances, even from a very young age.

Because when you understand the cause, you can move from managing symptoms to making targeted, personalised decisions.

Feeling worse after eating “healthy” foods?

Fish.
Spinach.
Fermented foods.

For some people, these don’t heal - they trigger symptoms.

You may be dealing with histamine intolerance.

At the centre of this is one key enzyme: DAO (Diamine Oxidase).

DAO is responsible for breaking down histamine from:
• the foods you eat
• your body’s immune response

But here’s the catch 👇
Your genetics determine how well DAO works.

If DAO activity is reduced, histamine can build up and affect multiple systems in the body:

• Gut - bloating, discomfort
• Brain - headaches, migraines
• Skin - rashes, flushing
• Cardiovascular - palpitations
• Respiratory - congestion

Same foods.
Very different reactions.

The good news?
This can be easily identified through genetic screening.

So instead of guessing, eliminating foods, and hoping for the best…
Find out for certain.

Breast health is not just about hormones.
It’s about how your body processes them.

When your body metabolises estrogen, it naturally produces free radicals.

In small amounts, this is normal.
But when oxidative stress builds up, it can:
• damage DNA
• increase cellular stress
• place pressure on repair systems
• contribute to long-term tissue vulnerability

This is where one key enzyme matters 👇
MnSOD (Manganese Superoxide Dismutase)

It acts as a powerful antioxidant, helping neutralise the free radicals generated during estrogen metabolism.

But here’s the key:

How well MnSOD works is genetically determined.

Some people have variants that reduce how effectively this enzyme protects their cells.

The good news?
This can be easily identified through genetic screening.

And if support is needed, there are targeted strategies to improve antioxidant defence and reduce oxidative stress.

This becomes especially important:
• during reproductive years
• when using the oral contraceptive pill
• during perimenopause and menopause
• when considering HRT or BHRT

Estrogen isn’t the problem.
Your ability to process it safely is what matters.

Move beyond generic advice.
Start personalising your breast health.

Breast cancer and the BRCA1 and BRCA2 genes became widely known after Angelina Jolie spoke publicly about her testing.

But many people still don’t fully understand what these genes actually do.

BRCA genes are tumour suppressor genes.

Every day, cells in your body experience DNA damage.
Normally, BRCA proteins help recognise and repair this damaged DNA before it develops into cancer.

When BRCA mutations are present, this repair system does not function as effectively.

That means supporting DNA protection and repair pathways becomes even more important.

This includes looking beyond just BRCA and considering other genes involved in tumour suppression and DNA repair, such as Quinone Reductase (NQO1) and TP53.

Understanding these pathways can help guide more personalised prevention strategies.

Because genetics isn’t just about risk - it’s about knowing where to focus your prevention efforts.

Prostate cancer affects around 1.5 million men globally each year.

It is one of the most common cancers in men.

Most people focus on one thing - PSA testing.

But there is another important factor many people overlook: Vitamin D receptor function.

Vitamin D does not simply work by circulating in the blood.
It produces its biological effects by binding to the Vitamin D Receptor (VDR) inside cells.

The VDR is present in prostate tissue and plays an important role in:
• supporting healthy cell differentiation
• suppressing abnormal cell proliferation

But here’s the key point.

How well your Vitamin D receptor responds to Vitamin D is genetically determined.

Some men have genetic variants that reduce how effectively the VDR functions.

In these cases, simply measuring Vitamin D levels or taking supplements may not be enough.

Genetic screening can identify when the Vitamin D receptor pathway needs additional support.

Because when it comes to prevention, understanding how your body responds at a genetic level can make a significant difference.
