The Claim

Consumption of less than 20 grams of nuts per day is estimated to be responsible for 4.4 million premature deaths globally in 2013, under the assumption of a causal relationship.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Cause and effect
1 study reviewed
In plain English

In 2013, an estimated 4.4 million premature deaths across four global regions occurred in people who consumed less than 20 grams of nuts per day.

See the scientific wording

The estimated 4.4 million premature deaths in 2013 across four global regions may be attributable to nut consumption below 20 grams per day, assuming a causal relationship, though this estimate is based on observational data and cannot confirm causation.

Why this might work

Eating nuts lowers harmful fats in the blood, reduces damage from free radicals, and calms chronic inflammation throughout the body. This protects the heart, lungs, and other organs from damage, improves how the body uses insulin, and strengthens the immune system’s ability to fight infections, which prevents early death.

  1. Study: Nut consumption and risk of cardiovascular disease, total cancer, all-cause and cause-specific mortality: a systematic review and dose-response meta-analysis of prospective studies

    The study found that people who ate more nuts were less likely to die early from heart disease, cancer, and other causes. It says that if everyone ate at least 20 grams of nuts a day, about 4.4 million deaths might have been prevented — but it can't prove nuts caused the lower death rates, only that they were linked.
