Sept 15 (UPI) – Walnuts do more than just add crunch to banana bread or muffins, according to new research suggesting that eating walnuts regularly early in life may lead to better health with age.

The researchers found that participants who ate walnuts in young to mid-adulthood were more likely to be more physically active, follow a higher-quality diet and develop a better heart disease risk profile as they got older.

They said this corresponds to 2020-2025 United States. Dietary Guidelines for AmericansRecommending eating nuts, such as walnuts, as part of a healthy diet.

the new the findings It appeared Thursday in the Journal of Nutrition, Metabolism, and Cardiovascular Disease.

For the study, researchers from the University of Minnesota School of Public Health reviewed 20 years of diet history and 30 years of physical and clinical measurements.

The new study, which was funded in part by the California Walnut Commission, a government agency founded in 1987, is part of a broader, long-term research: Study of the evolution of coronary artery risk in young peoplebetter known as CARDIA.

CARDIA, which explores the development of heart disease risk factors over time, is funded by the National Heart, Lung, and Blood Institute at the National Institutes of Health. It began tracking just over 3,000 adults between the ages of 18 and 30 in Birmingham, California, Chicago, Minneapolis, and Oakland, California in the mid-1980s.

Self-reported diet history was taken three times during the study: at baseline, at year 7 and year 20. Physical and clinical measurements were taken from multiple tests spanning over 30 years.

“Nut eaters appear to have a unique body phenotype that carries with it other positive effects on health such as better diet quality, especially when they start eating walnuts from young to mid-adulthood – as a risk of developing chronic diseases such as heart disease, obesity and diabetes,” said Lin M. Stephen. CARDIA Principal Investigator in a press release.

Walnuts “may act as a bridge or ‘food carrier’ to help people form healthy eating and lifestyle habits throughout life,” said Stephen, a professor of epidemiology and community health at the University of Minnesota School of Public Health.

Researchers note the unique properties of walnuts as the only nut that is an excellent source of the plant-based omega-3 alpha-linolenic acid (2.5 grams per ounce). previous search It is suggested that it may play a role in heart health, brain health, and healthy aging. Flaxseeds are also a good source of this type of omega-3 fatty acid.

Researchers note that one serving of walnuts, or roughly a handful, contains other healthy nutrients, including 4 grams of protein, 2 grams of fiber and 45 milligrams of magnesium. They said walnuts contain many antioxidants, including polyphenols.

The researchers said they looked for relationships between heart disease risk factors, including dietary intake, smoking, body composition, blood pressure, plasma lipids, fasting blood glucose and insulin concentrations, in 352 walnut consumers, 2,494 “other nuts” consumers and 177 Someone who didn’t. Do not eat nuts.

During the study, nut eaters ate about three-quarters of an ounce per day, while other nut consumers ate about 1.5 ounces. day.

After 30 years, nut consumers had higher self-reported physical activity scores than subjects in the ‘other nut’ and ‘without nut’ categories. They also have a better heart disease risk profile, with lower BMI, waist circumference, blood pressure and blood triglyceride levels.

The study said that nut eaters gained less weight during the study period, and fewer were classified as obese, compared to people in the other groups.
