What changes in the food industry created the Western diet and can be linked to chronic diseases such as coronary heart disease, diabetes, stroke and cancer?

by given steroid injection to animals

                                  and

                   increasing production of cheap calories of Sugar and Triglycerides  for use in food products

The attempt by farmers to maximize profit prompted them to give hormones e.g streroids to  animals to increase their  biochemical reactions therefore the the products yields e.g they  are  giving  steroids  to poultry  to  improve chicken, eggs production;and  to  cattle for improved beef and milk production.

In order to obtain maximum sugar and fats productions, cheap calories  forms of there  are being  produced. e,g fructose, maltose. if  maltose  is consumed in excess  it leads to  obesity, while fructose increases the level of cholesterol.These products  requires a lot of processing with different chemical products which leads to health problems after consumption

Explanation:

a. by using fur or clothes to trap heat energy near the body

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
