Science-Based Health Benefits of Pumpkin Seeds

It Promotes Heart Health

Unsaturated fats, in contrast to saturated fats, can help lower cholesterol levels in the blood. Pumpkin seeds contain a good amount of unsaturated fats, such as alpha-linolenic acid which is good for the heart. [19] Scientific evidence points to the effectiveness of alpha-linolenic acid in the prevention of cardiovascular disease when included in a balanced diet. [20]

A 2011 study with 35 postmenopausal women also showed that pumpkin seed oil was effective in improving their cholesterol levels. [21] It reduced the diastolic readings of their blood pressure by 7 percent and raised the levels of good cholesterol in their blood by 16 percent.

Some studies suggest that the positive health benefits of pumpkin seed to the heart are due to its ability to increase the production of nitric oxide in the body. [22] Nitric oxide helps widen the blood vessels. This improves blood flow and lowers the possibility of plaque clogging the arteries.
