Cashews: A Heart-Healthy Nut

Cashews are kidney-shaped seeds sourced from the cashew tree — a tropical tree native to Brazil but now cultivated in various warm climates across the world.

Cashews May Improve Heart Health

Diets rich in nuts, including cashews, have been consistently linked to a lower risk of disease, such as stroke and heart disease. Several studies show that eating cashews regularly may reduce blood pressure and triglyceride levels.

They May Help You Lose Weight

Nuts are rich in calories and fat. Hence, people wishing to lose weight have traditionally been advised to limit their nut intake. However, research is beginning to suggest that eating nuts, including cashews, may be beneficial for weight loss.

Cashews May Help Manage Type 2 Diabetes

People with type 2 diabetes may benefit from adding cashews to their diet. That's in part because cashews are a good source of fibre, a nutrient that helps prevent blood sugar spikes and which is believed to offer protection against type 2 diabetes.
