Chia seeds
Chia seeds are not commonly seen as "fatty" food, however, one ounce (28 grams) of chia seeds contains 11 grams of fat. Furthermore, practically all of the carbohydrates in chia seeds are fiber, therefore the great majority of calories in them are from fat. These aren't just any old fats. The bulk of the lipids in chia seeds is alpha-linolenic acid, a heart-healthy, important omega-3 fatty acid (ALA).
Chia seeds may potentially provide a variety of health advantages, including blood pressure reduction and anti-inflammatory properties. They are also quite nutritious. Chia seeds are high in nutrients in addition to being high in fiber and omega-3s.
