Question 1

What do E numbers and food additives actually do?

Accepted Answer

An E number is simply a **code indicating that an additive has been assessed and approved** for use in the EU and UK. It is a mark of regulatory evaluation, not a warning — which is the opposite of how it is usually read.

**How the numbering works**, and it is systematic:

**E100s** — colours.

**E200s** — preservatives.

**E300s** — antioxidants and acidity regulators. **Vitamin C is E300**, which is the example that usually reframes the whole subject.

**E400s** — thickeners, stabilisers and emulsifiers.

**E500s** — acidity regulators and anti-caking agents. Bicarbonate of soda is E500.

**E600s** — flavour enhancers.

**E900s** — glazing agents, sweeteners and others.

**What they are actually for:**

**Preservatives** prevent microbial growth, which prevents food poisoning. **Nitrites in cured meat** exist primarily to prevent botulism, a genuinely lethal risk, and the debate about them is a real trade-off rather than a simple story.

**Antioxidants** stop fats going rancid.

**Emulsifiers** keep mixtures from separating.

**Stabilisers and thickeners** provide texture, frequently allowing fat reduction.

**Colours** restore appearance lost in processing, or provide it.

**How safety is assessed.** Approval requires toxicological evaluation and an **acceptable daily intake** set well below the level at which no effect was observed, usually with a hundredfold safety margin. Approvals are reviewed, and additives have been **withdrawn or restricted** when evidence changed — several colours now require a warning label about effects on children's attention, and that is the system working rather than failing.

**What is fair to say critically:**

**"Natural" and "artificial" are poor guides to safety.** Many natural compounds are toxic; many synthetic ones are inert.

**Additives are a marker of processing**, and the health questions around highly processed food are mostly about the overall composition — energy density, fibre, salt, sugar — rather than the additives themselves.

**Individual sensitivities exist**, particularly to sulphites, and are worth knowing about.

Question 2

What does "organic" actually mean on a food label?

Accepted Answer

It is a legally regulated and certified term, not a marketing adjective — which distinguishes it from most claims on packaging. What it guarantees, however, is narrower than many buyers assume. What

Question 3

What do the different olive oil grades mean?

Accepted Answer

The grades describe how the oil was extracted and how much it has degraded — not, as many assume, how the olives were pressed or how many times. Extra virgin is the top grade. It is mechanically

Question 4

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

Question 5

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 6

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 7

What are the mother sauces?

Accepted Answer

Five foundational sauces codified in French cuisine, from which a large number of others are derived by addition. The system is a teaching structure more than a rulebook, and its value is in showing
