Melatonin is considered the most important hormone for sleep quality. This hormone is only produced by the body at night, playing a vital role in regulating the circadian rhythm, inducing sleepiness, and promoting restful, deep sleep.

Walnuts are a rich source of melatonin. Drinking walnut milk daily can improve sleep quality and alleviate conditions like insomnia and fatigue.

Researchers at the University of Wollongong (Australia) found that eating about 30g of walnuts per week for at least one year reduces the risk of type 2 diabetes by approximately 30% compared to those who don't consume nuts.

In a study conducted with 50 overweight participants diagnosed with diabetes, two groups were formed: one group added walnuts to their diet, while the other group followed a low-fat diet. After some time, the group consuming walnuts daily showed significant improvements in insulin levels due to the presence of unsaturated fats in their diet.

To manage blood pressure, adding walnuts to your diet is beneficial. The unsaturated fats in walnuts help supply essential nutrients to the body, reduce blood pressure, and stabilize it. Additionally, walnuts contribute to healthier arterial walls.

Blood pressure is the force that blood exerts on the walls of the arteries, essential for delivering blood to body tissues. It’s determined by both the heart’s contractions and the resistance of the arteries. To determine normal blood pressure, two key numbers are measured: systolic and diastolic pressure. The wider the gap between these numbers, the healthier the blood pressure. A narrow gap indicates higher risk of complications. Keep in mind that blood pressure fluctuates based on various factors, so monitoring it multiple times a day or month is recommended to confirm if hypertension is present.

In addition to its rich fat content, walnuts are also high in fiber. Studies have shown that eating walnuts increases the presence of beneficial bacteria in the gut, helping reduce inflammation and improve digestion.

However, frequent laxative use can cause inflammation in the intestines, leading to digestive problems.

Pregnant women often face stress and fatigue, and walnuts can help manage these issues effectively. Constipation, common during pregnancy, can also be alleviated due to the high fiber content in walnuts. These nuts provide essential nutrients such as Omega-3s, Vitamin E, phosphorus, and L-Arginine amino acids, all of which support both maternal and fetal health. The Omega-3 content in walnuts is over three times that of salmon, further promoting fetal brain development. Pregnant women who consume walnuts regularly can expect a smart and healthy baby. According to research from the Department of Public Health Nutrition in the United States, a nut-inclusive diet during pregnancy, including walnuts, can reduce the risk of allergies in children by 50%.
