Supports is higher

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

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

People who eat nuts have lower rates of death from heart disease and gastric cancer compared to those who do not.

See the scientific wording

Nut consumption is associated with reduced mortality from heart disease and gastric cancer.

Why this might work

Eating nuts lowers bad cholesterol and raises good cholesterol, which stabilizes fatty deposits in arteries and prevents them from bursting. Nuts also supply fats and minerals that calm the heart's electrical activity, stopping dangerous irregular beats that cause sudden death. At the same time, antioxidants in nuts reduce damage to blood vessels and lower chronic swelling in the body, which prevents arteries from narrowing and heart attacks from occurring.

What the research says

4 studies

  1. Study: Dietary components and risk of total, cancer and cardiovascular disease mortality in the Linxian Nutrition Intervention Trials cohort in China

    People who ate nuts a few times a month were less likely to die from heart disease, and the study suggests nuts may also help reduce deaths from stomach cancer, just like vegetables and beans do.

  2. Study: Nut consumption and decreased risk of sudden cardiac death in the Physicians' Health Study.

    People who ate nuts at least twice a week were much less likely to die suddenly from heart problems, and less likely to die from heart disease overall. But the study didn’t look at stomach cancer.

  3. Study: Association between nut consumption and mortality risk: a 20-year cohort study in Korea with a stratified analysis by health-related variables

    People who eat a handful or two of nuts each week are less likely to die from heart disease, but eating nuts doesn’t seem to lower the risk of dying from stomach cancer.

  4. Study: Nut consumption and risk of cardiovascular disease and ischemic heart disease mortality: The Adventist Health Study 2.

    People who ate more nuts were less likely to die from heart problems, according to this big study. But it didn’t look at stomach cancer, so we can’t say nuts help with that.
