COMPARISONS

What is already compared

Every comparison is a table of measurements from an official report: the substance, how much on one side, how much on the other, and the difference.

Composition in numbers

Cow milk VS Soy drink

Per 100 g. Milk with added vitamin D; soy drink unsweetened, shelf stable.

Composition in numbers

White rice VS Brown rice

Per 100 g cooked. The white rice is enriched with B vitamins — visible in the thiamin and folate rows.

Composition in numbers

Butter VS Olive oil

Per 100 g. Few rows: for olive oil the database has measured fatty acids, not vitamins and minerals.

Composition in numbers

Chicken breast VS Ground beef

Per 100 g raw. Both are raw: cooking changes water and fat and would make the sides incomparable.

BUILD YOUR OWN

Pick two categories

Only categories from the same family can be compared: they share properties, so the comparison means something. Pick the first and the rest will guide you.

HOW IT WORKS

From question to clear difference

  1. 01

    Choose categories

    The platform offers only categories that can be compared correctly — those from one family.

  2. 02

    Compare the same criteria

    Both sides are examined against one structure of properties and carry equal visual weight.

  3. 03

    Check the evidence

    Every material claim carries a source, a review date and its stated limitations.

  4. 04

    Make your own decision

    CONTRAST names no winner and does not replace professional advice.

Microplastics in tap and bottled water: what the review found

A systematic review of studies from 2010 to 2024 reports a wide range of microplastic counts: tap water from 0.7 particles per litre in rural areas to 1753 in urban surface water, bottled water up to 8934 particles per litre for the 1–50 µm range. The authors attribute the high bottled-water figures to packaging degradation.

OUR EVIDENCE STANDARD

Not just a claim. A verifiable chain.

We show the structure behind every meaningful statement — and the limits of what is currently known.

Source next to the claim

The source sits beside the information it supports.

Evidence types are separated

Studies, agency positions and reviews are visually distinct.

Uncertainty is visible

Insufficient and outdated information is given a status.

Partners do not shape conclusions

Advertisers have no influence on the content of comparisons.

WHERE WE STAND

We do not choose for people. We help them choose with clarity.

Most comparison services try to name a winner. CONTRAST shows the structure of the difference, the evidence behind each claim and the limits of what is currently known.
