By Shereen Jegtvig NEW YORK (Reuters Health) – The types of fat people get in their diet may not be as closely related to their risk of heart disease as previously believed, a new review of past studies suggests.

Polyunsaturated fats generally come from plant-based foods such as nuts, seeds and vegetable oils. Omega-3 fatty acids, a type of polyunsaturated fats, are found in fish.
