Protein, fat, and carbohydrates are called macronutrients. Vitamins
and minerals are referred to as micronutrients. All plant foods are a
mixture of protein, fat, and carbohydrate (the macronutrients). Even
a banana contains about 3.5 percent protein, almost the same as
mother's milk. Fruit and starchy vegetables, such as sweet potatoes,
corn, carrots, and butternut squash, are predominantly carbohydrate
but also contain some fat and protein. Green vegetables are about
half protein, a quarter carbohydrate, and a quarter fat. Legumes and
beans are about half carbohydrate, a quarter protein, and a quar-
ter fat.
One of the principles behind the health and weight-loss formula
in this book is not to be overly concerned about the macronutrient
balance; if you eat healthful foods, you will automatically get enough
of all three macronutrients as long as you do not consume too many
calories from white flour, sugar, and oil. So don't fear eating foods
rich in carbohydrates and don't be afraid of eating fruit because it
contains sugar. Even the plant foods that are high in carbohydrate
contain sufficient fiber and nutrients and are low enough in calories
to be considered nutritious. As long as they are unrefined, they
should not be excluded from your diet. In fact, it is impossible to
glean all the nutrients needed for optimal health if your diet does not
contain lots of carbohydrate-rich food.
Fresh fruits, beans and legumes, whole grains, and root vegeta-
bles are all examples of foods whose calories come mainly from car-
bohydrate. It is the nutrient-per-calorie ratio of these foods that
determines their food value. There is nothing wrong with carbohy-
drates; it is the empty-calorie, or refined, carbohydrates that are re-
sponsible for the bad reputation of carbs.
Understanding the Concept of Caloric Density
Because meats, dairy, and oils are so dense in calories, it is practically
impossible for us to eat them without consuming an excess of calo-
ries. These calorie-rich foods can pile up a huge number of calories
way before our stomachs are full and our hunger satisfied. However,
eating foods higher in nutrients and fiber and lower in calories al-
lows us to become satiated without consuming excess calories.
