Question 1

How common is food fraud, and which foods are affected?

Accepted Answer

**Food fraud** is the deliberate substitution, dilution, mislabelling or misrepresentation of food for economic gain. It is more widespread than most consumers assume, and it concentrates in predictable products.

**Why certain foods are targeted.** Fraud follows a simple logic: high value per unit, a cheap substitute that is hard to detect, a long and opaque supply chain, and consumers unable to verify quality. Products meeting all four are persistently affected.

**The most commonly documented:**

**Olive oil.** Extra virgin diluted with cheaper refined oils, or with entirely different seed oils, and false origin claims. Repeated investigations across decades have found substantial mislabelling rates.

**Honey.** Adulterated with sugar syrups — rice, corn or beet — which are difficult and expensive to detect, since testing methods and adulteration techniques have escalated against each other. Also false floral and geographic origin.

**Fish.** **Species substitution** is extremely common, with studies internationally finding high rates of mislabelling — cheaper species sold as expensive ones, particularly in restaurants and processed products where the whole fish is not visible.

**Spices**, especially saffron, paprika, turmeric, oregano and black pepper, bulked out with fillers, dyes or unrelated plant material.

**Meat.** Species substitution, as in the 2013 European horsemeat scandal, and false origin or welfare claims.

**Wine and spirits**, particularly high-value bottles, and false geographic designation.

**Organic certification fraud**, since organic commands a premium and the difference is invisible.

**Why it persists.** Supply chains cross many jurisdictions and intermediaries; testing is expensive; and penalties are often modest relative to profit.

**What reduces your exposure:** buying single-ingredient products in recognisable form (whole fish rather than fillets, whole spices rather than ground); buying from sellers with short, traceable supply chains; being sceptical of prices well below market; and looking for protected designation schemes, which carry verification.

**Most fraud is economic rather than dangerous** — though allergen and contamination risks are real.

Question 2

Is MSG actually bad for you?

Accepted Answer

The scientific consensus is that MSG is safe for the general population at normal dietary levels, and the reputation it acquired has not held up under testing. What it is. Monosodium glutamate is the

Question 3

How do restaurants handle allergies?

Accepted Answer

Through legal obligations, documented ingredient information and physical separation — and the quality of handling varies enormously, which is why how you ask matters as much as what you ask. The

Question 4

Does eating seasonally and locally actually matter?

Accepted Answer

For taste and cost, frequently yes. For environmental impact, far less than people assume — because transport is a small share of most foods' footprint, and the intuition that local always means

Question 5

What is the difference between "best before" and "use by"?

Accepted Answer

Use by is about safety. Best before is about quality. Confusing them causes both unnecessary waste and genuine risk, in opposite directions. Use by appears on foods that become unsafe as they age,

Question 6

What actually causes food poisoning, and which pathogens matter?

Accepted Answer

A small number of organisms account for most cases, and they behave differently enough that the same precaution does not work for all of them — which is why general advice to "cook things properly"

Question 7

Is the five-second rule real, and how does cross-contamination actually work?

Accepted Answer

No — transfer of bacteria to dropped food is effectively instantaneous — though the amount transferred does increase with contact time, which is the grain of truth the rule was built on. What matters
