Industrialization and Production
What technological advances enabled intensive meat and chicken production systems
Mechanization, climate control, automated feeding, and the introduction of biosecurity measures
Which part of the egg has the highest protein content, egg white or egg yolk?
Egg white contains the highest protein content compared to the egg yolk.
What is the primary purpose of adding nitrates and nitrites to cured meats?
The primary purpose of adding nitrates and nitrites to cured meats is to develop characteristic color and flavor, and to inhibit microbial growth.
What are two major environmental concerns associated with intensive meat production?
Greenhouse gas emissions and increased water/energy use
Name one biosecurity measure introduced in modern chicken farming
Climate-controlled environments and restricted access to facilities to prevent disease introduction
How do chicken diets influence the nutritional quality of eggs and meat?
Chicken diets can alter the nutritional quality of eggs and meat by changing their fatty acid composition and micronutrient levels.
What microorganism’s toxin formation is inhibited by nitrites, making cured meat safer?
Clostridium botulinum
Which food group has the highest average greenhouse gas emissions per calorie, based on US data?
Animal-based foods—especially meats
What is the "livestock revolution" and which regions are most affected?
Is the global increase in animal product consumption and production, mainly in developing countries
What is the difference between the nutritional profile of meat-based and plant-based diets?
Meat-based diets are generally higher in certain proteins and micronutrients, while plant-based diets may be higher in fiber and certain vitamins, but lower in some essential amino acids.
Name one or more health concers associated with nitrites and nitrosamines in processed meats.
A health concern with nitrites and nitrosamines is their possible carcinogenic, mutagenic, and teratogenic effects.
Explain the role of mechanization in increasing meat production and its environmental consequences.
Mechanization increases production but also creates social and environmental costs not reflected in final food prices, such as pollution and habitat loss.
Despite increases in the number of unnourished people, the number of obese people has also decreased alongside the production and consumption of meat, true or false:
True
Chicken cuts contain higher protein content and lower amounts of saturated fat compared to meat, true or false?
True
The nitrate-nitrite intake from natural sources is lower than that from processed foods, true of false
False
Which country is the leading egg producer worldwide?
China
Is defined as the worldwide increase in consumption and production of animal products, mostly in developing countries
Livestock revolution
Is an organic pigment present in the hemoglobin or red blood cells of chickens:
Protoporphyrin
Is not considered to be an essential component in curing mixtures
Nitrate
What role does biosecurity play in reducing environmental risks in modern chicken farms?
Biosecurity in modern chicken farms helps reduce environmental risks by preventing disease outbreaks that can lead to mass animal deaths and improper disposal, as well as minimizing the need for chemical interventions
