What Your Energy, Mood and Nervous System Might Be Telling You

For a long time, sugar carried most of the blame. And yes — excess sugar can absolutely place strain
on the body.

But there is another player in the modern food landscape that receives far less attention, yet quietly
places a demand on your metabolism and nervous system.

Refined starches.

Ingredients like maltodextrin, tapioca starch, corn flour, rice flour, and modified starches now
appear everywhere — especially in gluten-free products, sauces, and many foods marketed as better
choices.

On the surface, they often look harmless. Sometimes even reassuring.

Inside the body, however, the story can be very different.

How refined carbohydrates affect blood sugar and inflammation

Some refined starches can raise blood glucose even more rapidly than table sugar.

Maltodextrin, for example, can have a glycaemic index between 110 and 136, compared with table
sugar at around 65.

Because these carbohydrates are absorbed so quickly, they create sharp spikes in blood sugar and
insulin. Over time, frequent spikes can contribute to energy crashes, increased hunger, insulin
resistance, and ongoing inflammatory stress within the body.

This isn’t shared to create fear. It’s shared to create awareness. Because once you understand what
may be happening beneath the surface, you can begin to support your body more gently — and
more intentionally.

The hidden nutrient demands your body has to meet

Processing refined carbohydrates places a demand on key nutrients.

The body draws heavily on B-vitamins — particularly vitamin B1 (thiamine) — to metabolise these
foods effectively.

The challenge is that refined starches often come with very little of the nutrients the body needs to
handle them well.

So the body gives, and gives again.

Over time — especially during periods of stress, pregnancy, illness, or higher caffeine and alcohol
intake — this can leave some people running quietly low.

Low thiamine status doesn’t always present loudly. It often shows up as persistent fatigue, anxiety,
mood swings, nervous tension, disrupted sleep, or even nausea in early pregnancy.

Vitamin B1 plays a deeply supportive role in energy production, blood sugar regulation, nervous
system balance, immune support, and cognitive clarity.

When levels are sufficient, many systems simply run more smoothly in the background.

Why nutrient form and absorption can make a difference

The form of nutrients matters just as much as the dose.

Genetic variations such as MTHFR can influence how well synthetic vitamins are converted into their
active state. Many fortified foods contain folic acid, a synthetic form of vitamin B9. Some people
convert this without difficulty. Others do not. For those who struggle with conversion, the body may
still experience symptoms associated with low active folate despite adequate intake.

This is why, for some individuals, the form of the nutrient matters just as much as the amount.

Active forms such as methylfolate (B9), benfotiamine or TPP (B1), methylcobalamin (B12), and P5P
(B6) are often better utilised and more supportive.

Magnesium is another important part of this picture.

Diets higher in highly processed carbohydrates may increase the body’s demand for magnesium — a
mineral deeply involved in blood sugar regulation, nervous system calm, muscle relaxation, and
vitamin D activation.

When magnesium runs low, the body may feel more wired, more tired, more tense, or more easily
overwhelmed. Forms such as magnesium glycinate and magnesium threonate are often well
absorbed and commonly well tolerated.

Supporting your body without needing perfection

This isn’t about perfection.

It isn’t about removing every processed food overnight.

It’s an invitation to notice something many people have never been told:

Sometimes the body isn’t overreacting. Sometimes it’s under-supported. When you begin to
replenish what modern food patterns can quietly deplete, something starts to shift. Energy becomes
more stable. Mood softens. The nervous system begins to feel safer in its own rhythm.

Your body is not fragile. It is responsive, adaptive, and often waiting for the right support to arrive.

Your body understands more than you think. It just needs the right support.
