Elderly: 1 fruit a day is like a sleeping pill and protects the heart.

Insomnia is a common problem among older adults. The Sleep Foundation explains that changes in the brain and hormones that occur with age are the main causes of poor sleep quality.

The good news is that in a study recently published in the American Heart Association's journal JAHA , American scientists have found a great secret for people over 50 to sleep better, according to the medical news site News Medical.

To investigate the impact of avocado consumption on heart-healthy lifestyle habits and sleep quality, scientists at Penn State University (USA) conducted a study including 969 participants with an average age of 51, monitored for 26 weeks.

Participants were divided into two groups: One group ate one avocado per day, while the control group maintained their normal diet with the occasional avocado.

Results found that consuming one avocado per day significantly improved sleep quality, reduced blood fat levels, and improved diet quality.

Specifically as follows:

Positive impact on sleep of the elderly

People who consumed one avocado per day slept significantly better, with increased sleep duration.

Researchers believe that this may be due to the nutritional composition of avocados, which contain many substances that aid sleep. On average, 1 avocado contains Tryptophan (39 mg) - a precursor of melatonin that plays a role in regulating sleep; Folate (135 mcg) accounts for 30% of daily needs, involved in the production of melatonin; Magnesium (45 mg) accounts for 12% of daily needs, involved in the process of muscle contraction and relaxation.

Improve blood lipid levels

Consuming one avocado per day helps to reduce bad cholesterol and total cholesterol levels.

Researchers explain that avocados are high in fiber and good fats. In addition, 1 avocado contains 15 grams of monounsaturated fat, which can help lower bad cholesterol levels, reducing the risk of heart disease and stroke.

Improve diet quality

Eating one avocado a day can also significantly improve the quality of your diet.

The authors said: Avocados are a source of healthy fats and fiber that help improve diet quality and blood lipid (cholesterol) levels. In particular, the effect of avocados on sleep quality is most notable, according to News Medical.
