Intoleranța la lactoză schimbă meniul.

Because -a here is the Romanian definite article, attached to the end of the noun.

• intoleranță = intolerance
• intoleranța = the intolerance

Romanian usually puts the at the end of the noun instead of as a separate word. In this sentence, intoleranța la lactoză means lactose intolerance as a known condition, so the definite form sounds natural.

Yes, la often means to, at, or on, but in Romanian it is also the normal preposition used in some fixed expressions.

With intoleranță, Romanian commonly uses:

• intoleranță la lactoză
• intoleranță la gluten

So in this phrase, la is simply the standard preposition meaning to in the sense of intolerance to something.

Because lactoză is being used as a general substance name, not as a specific, previously identified thing.

So Romanian says:

• la lactoză = to lactose

not normally:

• la lactoza

You would only use the definite form lactoza in a more specific context, where the lactose is being singled out.

meniu means menu, and meniul means the menu.

Again, Romanian attaches the definite article to the noun:

• meniu = menu
• meniul = the menu

In this sentence, meniul can mean not just a restaurant menu, but more generally what someone eats, their food choices, or their diet/menu plan, depending on context.

Because the subject is intoleranța la lactoză, which is third person singular.

The verb is a schimba = to change.

Present tense:

• eu schimb = I change
• tu schimbi = you change
• el/ea schimbă = he/she/it changes

So:

• Intoleranța la lactoză schimbă meniul.
• Lactose intolerance changes the menu.

ă is a separate Romanian vowel. It is usually pronounced like the a in English sofa: a short uh sound.

So:

• schimbă ends with -ă, not plain -a
• lactoză also ends with -ă

This matters because Romanian diacritics are part of correct spelling, and they can change the form or meaning of a word.

A rough English-style approximation is:

in-to-le-RAN-tsa la lak-TO-zuh SKIM-buh MEH-nyool

A few important sounds:

• ț = ts, like in cats
• ă = a short uh
• iu in meniu sounds roughly like yoo

So:

• Intoleranța → in-to-le-RAN-tsa
• lactoză → lak-TO-zuh
• schimbă → SKIM-buh
• meniul → MEH-nyool

No, this is a very normal Romanian word order: subject + verb + object.

• Intoleranța la lactoză = subject
• schimbă = verb
• meniul = object

So the sentence is structured very much like English:

• Lactose intolerance changes the menu.

Romanian word order can be changed for emphasis, but this version is the most neutral and natural.

Not necessarily. It can be literal, but in many contexts it means that lactose intolerance changes what a person can eat.

So depending on context, meniul may suggest:

• the actual menu
• meal choices
• someone’s diet
• a planned list of foods

This kind of slightly broader meaning is very common in Romanian, just as menu in English can sometimes mean more than a restaurant card.

Yes, but the meaning or tone would change.

For example:

• Intoleranță la lactoză schimbă meniul sounds incomplete or unnatural in standard Romanian.
• Intoleranța la lactoză schimbă un meniu would mean Lactose intolerance changes a menu, which is less general and more specific to one menu.

So Intoleranța la lactoză schimbă meniul is the natural version if you mean the condition affects the menu or food choices in a general, understandable way.
