When a person ingests milk or other products containing Lactose, the undigested sugar in the milk or other products can ferment in the gut, causing a variety of unpleasant symptoms.
The end products of lipase digestion are monoglycerides and fatty acids.
The components of the human diet, as well as some problems that may arise from consuming a diet that does not provide the correct balance, are discussed in this section of the chapter.
Natural sources of sugars include fruits, vegetables, milk, and honey.
Lactose and table sugar are disaccharides.
Monosaccharides are absorbed into the bloodstream and delivered to cells.
Monosaccharides are converted to glucose inside animal cells, which is used for the production of ATP by cellular respiration.
Animals and plants store glucose in different ways.
Beans, peas, and cereals are good sources of starch.
Excess sugar is stored in the stomach as glycogen.
The human body can only store 600 g of sugar in the form of glycogen, which is converted into fat and stored in the body's tissues.
The time it takes for an animal to be eaten for food is not as long as other animals.
Animal foods do not have high levels of carbohydrates.
Beans, peas, nuts, fruits, and vegetables are rich in fiber.
A slice of bread made from whole-wheat flour contains 3 g of fiber, while a slice of bread made from refined wheat flour has less than 1 g of fiber.
Fiber can't be absorbed into the bloodstream by small molecule that enter the bloodstream.
Insoluble fiber adds bulk to fecal material, which makes it less likely that you'll get sick.
bile acids and cholesterol are prevented from being absorbed bysoluble fiber in the small intestine.
High-fiber diet may protect against heart disease.
The recommended daily intake of fiber for women and men is 25 g and 38 g, respectively.
To increase your fiber intake, eat whole-grain foods, snack on fresh fruits and vegetables, and include nuts and beans in your diet.
If you or someone you know has lost weight by following a low-fat diet, you may think that "carbs" are not good for you.
Some low-carbohydrate, high-fat diet are potentially hazardous and have no benefits over a balanced diet that includes the same number of calories.
A recent study of over 4,400 Canadian adults found that people who consumed about half of their calories from sugars had the lowest risk of being obese.
The traditional diet in some countries is 70% high-fiber, and these people have a low incidence of diseases that plague Americans.
A current controversy in human nutrition is the relative risk of consuming high levels of high-fructose corn syrup.
Corn sugar, also known as corn sugar, is the most commonly used sweetening agent, used in soft drinks and a huge variety of foods.
It is likely that people who consume a high percentage of empty calories in the form of simple sugars are more likely to be obese.
Delayed growth and skin problems can occur in people who consume an insufficient amount of these essential unsaturated fatty acids, which are found in high amounts in certain fish and in plant oils.
It is used as a starting point for the synthesis of various compounds.
The cholesterol in plant foods is not as high as it is in animal foods.
The number one cause of disease related death in the United States is cardiovascular disease, caused by elevated blood cholesterol levels.
Statistics show that trans fat is more harmful than saturated fat.
In shortening and some margarines, trans fat acids arise when the oils are hydrogenated to produce a solid fat.
Trans fats may affect the function of the cholesterol blocker in the body.
Cookies and crackers, french fries, and packaged snacks contain trans fats.
Meat, pork, poultry, eggs, and dairy products are considered complete or high-quality when they contain all of the essential amino acids.
The high-lysine corn that has been produced through genetic engineering technology has a low content of the essential lysine.
Approximately 3% of Americans and millions of people in other countries are either vegetarian or vegan.
Neither group needs to rely on animal sources.
Grains, beans, and nuts can be eaten by vegetarians and vegan.
Tofu, soymilk, and other foods made from processed soybeans are complete sources of nutrition.
A report from the American Dietetic Association states that a vegetarian diet is appropriate for all stages of a person's life cycle.
Most Americans probably don't get a life threatening deficiency in their diet.
Some health food stores have supplements for athletes who are trying to build muscle mass.
According to the American and Canadian Dietetic Associations, athletes should only consume 1 to 1.5 grams of protein per kilogram of body weight per day, which is slightly higher than the 0.8 gram per kilogram recommended for sedentary people.
An inactive 150 pound person would need to consume about 60 grams of food-like substance per day, which is about the amount contained in two cheeseburgers.
Dehydration can occur when a person is exercising and losing water by sweating.
Calcium loss in the urine can be increased by a high-protein diet.
High-protein foods derived from animals often contain a high amount of fat, and some plant proteins may cause problems for those who have immune reactions toGluten.
