discuss how people used high sugar or high salt to preserve food?

Expert Solution

Answer-

Long before the invention of refrigerator, foods where cured using a mixture of sugar and salt in combination with smoking. This combination of sugar and salt as food preservative helps to increase osmotic pressure thus destroying the harmful bacteria and slowing decay alongwith promoting the build up of beneficial bacteria and rich taste.

Curing foods by salt or sugar draws water out and ties up the water within thus preventing the food from any kind of reactions that leads to decay.

It is recomended to use salts containing nitrates as they act as antioxidants in food preservatives. They undergo free radical and oxidation mechanisms thus prevent food spoilage.

Similarly, Food and Agriculture Organisation(FAO) recommends the use of sucrose and fructose instead glucose as a food preservative. They also promote the growth of healthy bacteria that will prevent any sickness post consumption of the food.

Describe how high dietary sugar diets could promote insulin resistance. Be sure to 1) discuss how dietary sugar gets digested/absorbed 2) explain the fate of glucose into the muscle cell in insulin-sensitive states then how it could lead to insulin resistance as well as 3) identify how sugar interacts with exercise (before, during and immediately after) to foster movement. Highlight cell mechanisms and key hormones within answers when possible.

Salt-free diets are often prescribed to people with high blood pressure. The following data values were obtained from an experiment designed to estimate the reduction in diastolic blood pres- sure as a result of consuming a salt-free diet for 2 weeks. Assume diastolic readings to be normally distributed. (a) Calculate a 90% confidence interval for the mean reduction. (b) Is there evidence that diastolic blood pressure is reduced by having salt-free diets, use α = 0.05. Patients A. B. C....
