How is yogurt made?
Correct Answer
B. By adding live bacteria to milk.
Explanation
Yogurt is made by adding live bacteria to milk. The live bacteria, specifically Lactobacillus bulgaricus and Streptococcus thermophilus, ferment the lactose in the milk, converting it into lactic acid. This process thickens the milk and gives yogurt its tangy flavor. The live bacteria also produce probiotics, which are beneficial for gut health. Mixing milk with cheese, freezing milk, or letting milk age are not the correct processes for making yogurt.

Yogurt is particularly rich in protein, making it a beneficial food for promoting muscle growth and maintenance, improving satiety, and supporting overall health and wellness. Additionally, yogurt also provides other important nutrients like calcium, vitamins, and probiotics, which further contribute to its nutritional value.
6.
What does the casein contained in yogurt do to your body?
Correct Answer
D. It promotes lower blood pressure.
Explanation
Casein is a protein found in yogurt that has been shown to have a positive effect on blood pressure. Consuming casein can help lower blood pressure levels, as it contains bioactive peptides that act as ACE inhibitors, which help relax blood vessels and improve blood flow. This can ultimately lead to a reduction in blood pressure.
7.
How much whey can be found in yogurt?
Correct Answer
A. 20%

10.
How is the family of trans fat found in yogurt called?
Correct Answer
D. Ruminant.
Explanation
The family of trans fat found in yogurt is called ruminant. Ruminant trans fats are produced by the digestive system of ruminant animals such as cows, sheep, and goats. These animals have a unique ability to convert dietary unsaturated fatty acids into trans fats through microbial fermentation in their rumen. The trans fats produced in this process have different chemical structures compared to industrially produced trans fats, making them less harmful to human health. Therefore, the correct answer is ruminant.
