Oats BY Karamazov Oats and the Effects on Cholesterol Do they really lower cholesterol or is the claim used for marketing schemes? Studies have been done, and they show that eating Oatmeal does lower cholesterol. According to an article written by Charles G. Humble, Oatmeal’s fiber content (7%) is low compared to that of oat brands (15-26%). The study that was done showed that oat bran consumption was associated with twelve percent reduction in total cholesterol compared with wheat bran consumption. In this experiment, they had twelve healthy college students supplement their normal diet with four muffins that ad fifty grams of wheat bran.They did this for six weeks, and after six weeks they substituted wheat bran muffins for oat bran. The week that these students ate oat bran had twice the reduction of total cholesterol.
(Humble, 1) In another study, Kristin M Bugle, did a double blinded, randomized crossover study. She had twenty-four volunteers that had their diet monitored for two weeks. The study was similar to one mentioned above, but in this case they had one week controlled with a low fiber diet and the second week the volunteers had an oat bran diet, consuming about 102+ grams a day. The results showed that cholesterol creased by 14% during the week of oat bran diet.
An even higher percentage of 16% percent decrease in HAD cholesterol (non-high-density lepidopterist) during oat bran diet compared to the week of low fiber diet, which only decreased cholesterol three percent. (Bugle, 2) From the Journal Preventive Medicine, there was an article based on a study that also showed a significant amount of decrease in cholesterol with an oat fiber diet. Two 236 participants were recruited in front of a National bank, Chicago.
This study was constructed for twelve weeks and every four weeks data was collected about heir weight, serum lipid levels, their food records.The participants followed a diet that was recommended by the American Heart Association. After four weeks, the participants were then randomly assigned two groups. The first group was told to include 56 grams of oatmeal to substitute for other carbohydrates. The second group was told not to consume any oat products. Both groups still were ordered to follow the recommended American Heart Association diet. Before both groups were assigned whether or not to consume oats, the cholesterol levels for both groups were about the same.
However, when each group was respectively told to consume or not consume oats, there were leaps of difference between the two. In the group that was told to intake oats, the average cholesterol level was reduced to 6. 8%. The other group that did not consume oats only had an average of 2. 8% cholesterol reduced.
Just like the studies mentioned previously, this Just shows that oats do help in lowering cholesterol levels. (Preventive Medicine) The earliest study I came across was from The Lancet, done by De Grotto. This experiment took 6 albino male rats and 6 albino female rats.
The rats were fed in a ay that they would obtain high cholesterol. They then were fed with substances like whole wheat, rice, barley, and rolled oats to see if there were any significant changes The one that lowered the most cholesterol was rolled oats at 27. 4%. This then was carried on with 21 male volunteers, 30-50 years of age. Within three weeks they were asked to eat daily: egg of bread that contained egg of rolled oats in substitution of their “normal” bread.
Before the volunteers were asked to take oat bread, the average cholesterol level was 251 MGM and it dropped within the first of eating rolled oats to 239 MGM per 100 ml.
