Why Does Everything Hurt My Gut? A Guide to Modern Food Allergens & Safe Sweet Treats

If you had told me ten years ago that reading a snack ingredient label would feel like sitting a chemistry exam, I wouldn’t have believed you. Yet here we are! As a vegan with a gluten and dairy intolerance, along with a sensitive gut courtesy of Irritable Bowel Syndrome, treat shopping often feels like navigating a minefield.Why on earth is milk powder added into everything these days?

If you’ve found yourself wondering why it feels like half of the population is suddenly dodging dairy, avoiding gluten, or reacting to ingredients that our grandparents ate without a second thought, then let’s break down what’s actually happening with modern food and our bodies.

Allergies vs. Intolerances: What’s The Difference?

Before diving into why modern food seems to be so tricky, it helps to clear up the jargon first. People often use the words allergy and intolerance interchangeably, but medically, they’re quite different:

Food allergies are an immune system reaction, where our body mistakenly identifies a specific protein in food like peanuts or shellfish as a dangerous invader and releases antibodies and histamine to fight it off. Symptoms can range from hives and swelling to life-threatening anaphylaxis.

Whereas food intolerances and sensitivities are a digestive system reaction. They usually happen when our body lacks the specific enzymes needed to break down certain foods like lacking lactase to process the sugars in dairy. While not usually life-threatening, they result in bloating, cramps and distress which can be deeply uncomfortable.

Gut Disorders like IBS aren’t a food allergy or a single intolerance, but a functional gastrointestinal disorder. A sensitive gut can react strongly to fermentable carbohydrates known as FODMAPs, artificial additives, or sudden shifts in fibre, turning everyday eating into a guessing game and dash to the bathroom.

Why Is Modern Food Causing Us So Many Problems?

You haven’t imagined it, more people than ever are managing daily food restrictions, as scientists and nutritionists point to a few key factors behind this sudden spike. Modern food production relies heavily on processing aids, emulsifiers, artificial flavours and refined starches to extend shelf life and lower costs. Ingredients like milk derivatives, wheat starches, and soy lecithin end up added to foods that naturally shouldn’t contain them at all.

Our gut health relies on a complex ecosystem of trillions of bacteria, and so, factors like antibiotic use, ultra-processed diets, and pristine modern sanitation have changed the diversity of our gut microbiomes, making our digestive systems less resilient and more prone to reactivity.

For vegans and those avoiding animal products, sweet treats are a notorious trap. Traditional confectionery, especially marshmallows and gummy sweets, almost always rely on gelatine which is made from animal collagen, alongside dairy derivatives and artificial colours.

Finding Joy In The Free From Aisle

When you are managing multiple dietary boundaries, as I do, finding simple, comforting treats can feel almost impossible. You often end up with snacks that taste like cardboard or leave you doubled over in pain just an hour later.

Marshmallows used to be an ultimate off-limits food for me, as traditional versions are a triple-threat of gelatine, potential gluten cross-contamination, and unnecessary additives. But the Free From Fellows Vanilla Vegan Mallows are little clouds of vanilla goodness, fully approved on my restrictive diet checklist.

Being 100% gelatine-free, they are approved by both The Vegan Society and The Vegetarian Society, so there’s zero stress about animal by-products. they are also completely safe for coeliacs, those with non-coeliac gluten sensitivity, and anyone avoiding dairy or gluten.

Many plant-based marshmallows end up dense or sticky in comparison, but these manage to get that classic, super fluffy, pillow-soft, squishy texture just right. And as they are made with natural flavourings, it’s is a massive relief for anyone with IBS who triggers easily on synthetic additives.

Whether you toss a handful into a cup of hot chocolate with oat milk, toast them over an open flame, or snack on them straight out of the bag whenever a sweet craving strikes, they deliver a classic childhood nostalgia without any of the gut-wrecking consequences.

Living with food intolerances, IBS, or an ethical diet like veganism doesn’t mean giving up on all of the delicious food that you love and cherish from childhood. It just means being a little more selective and knowing about which brands genuinely understand dietary needs rather than just treating them as a buzzword.
