"Food builds big bridges. If you can eat with someone, you can learn from them, and, when you learn from someone, you can make big changes. We changed the courses of America in this restaurant over bowls of gumbo. We can talk to each other and relate to each other when we eat together."
- Chef Leah Chase

Carbohydrates are often associated with having a negative impact on health and/or not being necessary at all, when, in fact, the opposite is true. Carbohydrates are essential and, therefore, should constitute most of an individual's daily caloric intake (45-65% per USDA guidelines). Animals, including humans, are perpetually linked to plants as all carbohydrates come from plants. -
Lipids are important molecules that serve different roles in the human body. A common misconception is that fat is simply fattening. Lipids are essential for cell membranes, hormone production, and energy storage.

Protein is a vital constituent of all organs in the body and is required to perform a vast variety of functions. Therefore, protein is an essential nutrient that must be consumed in the diet. Your protein-rich muscles allow for body strength and movement, which enable you to enjoy many activities.
