A. gallstones

B. ulcers

C. goiters

D. allergies

Answer Explanation:

A) gallstones

- Correct: Hardened deposits of cholesterol that accumulate in the structure that stores bile, which is the gallbladder, are known as gallstones. Gallstones can also contain other substances, such as bilirubin or calcium salts, in addition to cholesterol. These stones can vary in size and may cause symptoms such as abdominal pain, nausea, and jaundice. In severe cases, gallstones may require medical intervention, including surgery, to remove them.

B) ulcers

- Incorrect: Ulcers are sores or lesions that develop in the lining of the digestive tract, commonly in the stomach (gastric ulcers) or the upper part of the small intestine (duodenal ulcers). They are not related to hardened deposits of cholesterol in the gallbladder.

C) goiters

- Incorrect: Goiters are abnormal enlargements of the thyroid gland in the neck. They can be caused by iodine deficiency, thyroid disorders, or other factors, but they are not related to gallstones.

D) allergies

- Incorrect: Allergies are immune responses to specific substances (allergens) that the body perceives as harmful, leading to symptoms such as sneezing, itching, or anaphylaxis. They are not related to hardened deposits of cholesterol in the gallbladder.

Therefore, the Correct Answer is A.

Q #1: Which foods should be included in a balanced diet as a good source of roughage?

A. red meat and poultry

B. fresh fruits and vegetables

C. eggs and milk products

D. animal fat and plant oil

Answer Explanation

B) fresh fruits and vegetables

- Correct: Fresh fruits and vegetables are excellent sources of roughage, also known as dietary fiber. These foods provide insoluble fiber, soluble fiber, or a combination of both, which adds bulk to the stool and promotes healthy digestion. Insoluble fiber, found in foods like leafy greens, celery, and broccoli, helps to move food through the digestive tract, preventing constipation. Soluble fiber, found in foods like apples, oats, and beans, can help lower cholesterol levels and regulate blood sugar levels.

A) red meat and poultry

- Incorrect: While red meat and poultry are good sources of protein and other nutrients, they are not significant sources of dietary fiber or roughage. These foods do not contribute to the fiber content of the diet.

C) eggs and milk products

- Incorrect: Eggs and milk products are valuable sources of protein, vitamins, and minerals, but they are not significant sources of dietary fiber or roughage. These foods do not provide the fiber needed for healthy digestion.

D) animal fat and plant oil

- Incorrect: Animal fat and plant oils are sources of dietary fat, which is important for providing energy and essential fatty acids in the diet. However, they do not contain significant amounts of dietary fiber or roughage. These foods do not contribute to the fiber content of the diet.
