But when does adding fat make sense, and when is it a bad idea?

But are any of these oils really special?

For example, lard contains a lot of saturated fatty acids but also a lot of monounsaturated fatty acids.

Here are the types:

Saturated fatty acidswere once demonized, but arenow earning back some respect.

Monounsaturated (omega-9) fatty acidsare considered heart-healthy good fats.

Their best-known sources include olive oil and avocados.

But biochemically speaking, does adding fat to food help vitamin absorption?

The same is true ofsalads that contain eggs, since the yolk contains fat.

Now, if the beverage youre talking about is a smoothie, theres more reason to add fat.

A smoothie is essentially food in liquid form.

Too often, smoothies just contain carbohydrates, but a healthy, filling smoothieshould contain protein and fat too.

These additions make the smoothie more filling, and slow down the sugars rush into your bloodstream.

But remember youre just filling out ahealthy ratio of macronutrients, not applying a magic elixir.
