The Claim
Consuming approximately 15 grams of walnuts per day is associated with a reduction in all-cause mortality risk.
What the research says
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.
People who eat about 15 grams of walnuts each day have a lower risk of dying from any cause compared to those who do not.
See the scientific wording
Consuming walnuts at approximately 15 grams per day is associated with reduced mortality risk.
Eating walnuts introduces special fats and plant compounds into the body that lower bad cholesterol, reduce inflammation in blood vessels, and protect cells from damage. This prevents clogged arteries, weakens the risk of heart attacks and strokes, and reduces damage from chronic diseases like cancer and lung illness, leading to longer life.
What the research says
5 studiesPeople who ate walnuts every day as part of a diet lost weight just like others, but their 'bad' cholesterol went down and their blood pressure stayed healthier over time—both things that help people live longer.
People who ate walnuts every day, even just a small handful, lived longer than those who didn’t eat them. The more walnuts they ate, the longer they tended to live.
People who ate more walnuts and other nuts lived longer, especially from heart disease. Even small amounts seem to help.
Eating a small handful of walnuts every day helps lower bad cholesterol and fats in the blood, which are linked to heart disease — one of the main reasons people die early. So, this study suggests walnuts might help people live longer.
