Star Ingredient:

Butternut Squash Contain:


What is manganese? A trace mineral essential for the body to metabolize fats and carbohydrates.  In the body, it is found mostly in the bones and glands and is a cofactor for many enzymes, helping to facilitate dozens of metabolic processes.  Manganese requirements are low, and plant foods such as nuts, whole grains, and green leafy vegetables contain significant amounts of this trace mineral.  Deficiencies are therefore unlikely.

Vitamin A*

When most people think of vitamin A, they think of their eyes. When vitamin A is lacking, the eye has difficulty adapting to changing light levels. Vitamin A is a versatile vitamin that also is involved with protein synthesis, reproduction and growth. The role that vitamin A plays in vision is undeniably important, but only one-thousandth of the body’s vitamin A is in the retina.  Much more is in the skin and the linings of organs, where it participates in protein synthesis and cell differentiation.

Vitamin C*

Did you know the human body does not have the ability to produce vitamin C on its own? That’s why it’s so important to make sure we are eating a wide variety of foods with Vitamin C.  This vital vitamin is not only useful to help our bodies fight off the common cold, but it’s necessary for the absorption of iron and very important for our connective tissues. Connective tissues are what keep our skin firm and our muscles strong. Because vitamin C supports our connective tissues, it is also useful in speeding up the healing process. If you have a wound, you might want to consider increasing the intake of foods higher in vitamin C.

Trivia:  Cats and dogs can make vitamin C therefore they don’t need fruits and vegetables.
