Study Notes

Importance of Vegetables

Vegetables are packed with vitamins, minerals, and carbohydrates, providing energy without excess calories.
Leafy, dark-green "super vegetables" like kale and spinach are rich in vitamins A and C, and calcium.
These nutrients help maintain healthy eyes, strong bones, and quick healing.

Fiber in Vegetables

Fiber is the part of the plant that the body can't easily break down, like the strings of celery.
Eating enough fiber helps with regular bowel movements and comfortable digestion.

Grains

Grains are small, hard, dry fruits of tall grasses, such as corn, wheat, rice, millet, and barley.
A grain kernel is made up of three parts: bran, germ, and endosperm.
Whole grains provide fiber, vitamins, and minerals, while refined grains lack these nutrients.

Types of Bread

Brown breads are made from whole grains, providing more nutrients and fiber due to the inclusion of bran and germ.
White breads are made from refined grains, lacking nutrients and fiber due to the removal of bran and germ.

Popcorn

Popcorn is a special type of corn that pops due to the hard bran and endosperm, which traps steam and builds pressure until the kernel bursts.

Protein Foods

Protein foods include meat, poultry, seafood, eggs, beans, tofu, and nuts, which are essential for building and repairing body tissues.
Proteins are built from amino acids, with the body needing all types of amino acids to function properly.
Meat, fish, poultry, and eggs contain the full set of amino acids, while plant-based foods can provide the full set through a balanced diet.

Lean Meats vs. Fatty Meats

Fat is a necessary nutrient, but some fats are healthier than others.
Lean meats like chicken and turkey, and good fats like those found in fish, nuts, avocados, tofu, and beans, are healthier than fatty meats like red meats.
