Lethbridge Herald, The (Newspaper) - March 1, 1973, Lethbridge, Alberta 13 THE UTH3R1DGI HERALD Ihimday, March 1, 1973 LAWRENCE E. LAMB, M. D. Cholesterol varies with individuals Dear Dr. Lamb How does a physician delennine whether a patient's cholesterol elevation is hereditary? When I last vis- ited my doctor he Informed me that my cholesterol was slightly elevated but not to worry about it to Irim fat off my meat, no butter, no bacon. No list of verbolen foods was given to me but I have done some re- search on this so I am ques- tioning that particular aspect. Since I am on the lean side and have normal blood pres- sure, I questioned the reason as to the elevation. He replied that it was hereditary and he did not seem to want to discuss the matter further. Now I have a friend who is a b o u t 60 pounds overweight and does taka medication for hyperten sion. Her doctor informs Irer not to worry about her cholest crol, that if it rises it will re- turn to normal. I am puzzled and like an answer to these apparently conflictini statements. Dear Reader Some scien- tists think that whatever our levels of cholesterol are they are hereditary or at least re- lated lo our genes. Of course, that can mean that we inherit a chemical characteristic that causes us to have elevated cho- eslerol levels when our living habits are not optimal. In oth- er words, our body wasn't de- signed to eat as much rich food as our society does and to be as inactive as we frequently are. Nature designed the hu- man body to be considerably more active and to eat an en- tirely different type of fare than civilization currently pro- vides. Some individuals have very high elevations in their choles- terol and other indications of abnormal fat metabolism pec- uliar to their family. They may have a family tendency to early heart attacks. These individli als are relatively raie compar ed to the total population o individuals who have a les? jnarked chemical problem aru aren't constructed to handle mndern living patterns.

The cholesterol level ca fluctuate in some individuals Indents with cholesterol leve! eterrainations at the time ol teir term examinations were ound to have sharp elevations vhich dropped to normal after he examinations were over The elevations that are import ant are those that are persist ent. A large number" of these can be decreased to rclativcls ow values by restricting one's otal caloric intake to the poin .hat all significant excess fa deposits in the body are elim mated. Now there will still be som individuals who even after they are truly lean will still have high cholesterol. These indiv- iduals need to curtail their total fat intake awl frequently their saturated fats found primarily in animal foods and many doc- tors think they should also lim- it their cholesterol intake. If you limit the number of calor- ies eaten and still get a good balanced diet it means you are going to have to restrict high calorie foods which include both Ask Andy The Gulf Stream Andy sends a complete 20- volume set of the Merit Stu- dents Encyclopedia to Jack Evans, age 10, of San Diego, California, for his question: What causes Itie' Gulf Stream? In some places, you can sail a mile across the Mississippi dip down 100 feet. It car- ries four million tons of water on its long journey to the sea The Gulf Stream carries four billion tons of much deeper wider water and the round trip may be miles or more. Obviously the forces tha run it must be extremely pow rful. Let's picture the Gulf Stream as an enormous water whee jddying around tiie North A1 antic.
