Where do calories come from? Carbohydrates Proteins Fats

Carbohydrates

Principal source of fuel for our bodies. Combination of carbon, hydrogen,

oxygen. Guidelines suggest

55-60% of our diet should be carbohydrates.

Not all carbs are created equal!

Some are simple and easily digestible. quickly raise blood sugar (glucose) insulin flood soaks up glucose looking for more – cravings More refined foods

white potato, white rice, white pasta, soda, juices, sweets

Fruits

Not all carbs are created equal!

Some are complex and digested more slowly. Broken down more slowly or

not at all (fiber). More staying power Less refined foods – plant based

whole grain breads and cereals, veggies

Fiber Rocks! Soluble fiber dissolves

and becomes “gummy” creating a sense of fullness and traps cholesterol. Apples, citrus fruit, and carrots

Insoluble fiber or roughage speeds the passage of food through the intestines. Wheat bran, whole grains, and veggies

Net carbs

Proteins

Growth and repair of all human tissue. Chains of amino acids

Complete – full compliment of amino acids Red meat, poultry, fish, eggs, dairy

Incomplete – lacking one or more amino acids

Vegetable proteins

How much protein do we need?

Current guidelines 10-15% with some consensus of no more than 30% of daily diet.

Lean protein is better! Red meat only

occasionally. Fish, nuts,

poultry, and beans

Fats Need for storage of energy,

insulation of body temperature and transport of vitamins A, D, E, & K.

Recommended daily allowance is about 30% fats.

Fats: the good, the bad, and the ugly!

Good:Monounsaturated and Polyunsaturated increases HDL or “good cholesterol”.

Nuts, seeds, fish, and most vegetable oils (canola, olive, sunflower, corn…)

Saturated fats (the bad)and trans-unsaturated fats (the ugly) increase LDL or “bad cholesterol” and triglycerides.

Red meat, ice cream, butter (sat fats) Margarine, processed foods like

Hostess Twinkies, fried foods, “partially hydrogenated” (trans fats)

Eat Vegetables in Abundance and Fruits Frequently!

Fruits and veggies are packed with phytochemicals. Vitamins Carotenoids Flavonoids Indoles Isoflavones and phytosterols
