Questions: Question 60 Food restriction may extend the lifespan by preventing: a, hormone synthesis. b. gene suppression. c. protein accumulation. d. lipid oxidation. e, insulin reduction. Moving to the next

The answer is c: protein accumulation.

Explanation for each option:

a. Hormone synthesis: Food restriction does not primarily extend lifespan by preventing hormone synthesis. Hormones are essential for various bodily functions, and their synthesis is not directly linked to lifespan extension through dietary restriction.

b. Gene suppression: While gene expression can be influenced by diet, food restriction is not primarily known for preventing gene suppression as a mechanism for extending lifespan.

c. Protein accumulation: Caloric restriction has been shown to reduce the accumulation of damaged or misfolded proteins, which can contribute to aging and age-related diseases. This reduction in protein accumulation is one of the mechanisms by which lifespan may be extended.

d. Lipid oxidation: While lipid oxidation can be harmful, food restriction is not primarily known for preventing lipid oxidation as a mechanism for extending lifespan.

e. Insulin reduction: Food restriction can lead to reduced insulin levels, but this is not the primary mechanism by which it extends lifespan. Instead, it is more about improving insulin sensitivity rather than preventing insulin reduction.

In summary, the primary mechanism by which food restriction may extend lifespan is by preventing protein accumulation.
