Quick Scoop: The main downsides of palm oil are environmental: it has been linked to deforestation, habitat loss, biodiversity decline, greenhouse-gas emissions, and water pollution from plantation waste. Health concerns also come up because palm oil is high in saturated fat, which can raise LDL cholesterol when eaten in large amounts.

What people worry about

  • Deforestation: Forests are cleared to make room for plantations, which destroys carbon-storing ecosystems and pushes wildlife out of its habitat.
    • [7][2]
  • Species loss: Orangutans, tigers, elephants, and other endangered animals can lose critical habitat when forests are converted to palm plantations.
    • [2][7]
  • Pollution: Waste from processing, especially palm oil mill effluent, can contaminate waterways and harm aquatic life.
    • [3][2]
  • Climate impact: Clearing forests and peatlands releases large amounts of carbon dioxide, adding to climate change.
    • [2]
  • Health concerns: Palm oil is roughly half saturated fat, so eating a lot of it may raise cholesterol and heart-disease risk.

Why it stays controversial

Palm oil is very efficient to grow, so supporters argue it can produce more oil on less land than some alternatives. Critics say that benefit only matters if production is truly sustainable, because the environmental damage can be severe when forests and peatlands are cleared.

Bottom line

The biggest problem with palm oil is usually not the oil itself, but how it is produced. If you want to avoid the worst effects, look for certified sustainable palm oil or reduce heavily processed foods that use it.

TL;DR: Palm oil’s biggest drawbacks are deforestation, wildlife loss, pollution, and climate harm; on the health side, it’s high in saturated fat and can affect cholesterol if consumed often.
