A small study titled “Acute Effect of Oatmeal on Subjective Measures of Appetite and Satiety Compared to Ready-to-Eat Breakfast Cereal: A Randomized Crossover Study” was recently published in the Journal of the American College of Nutrition.
The study showed that a simple low caloric, high satisfaction breakfast primarily of oatmeal “can prolong the period between meals and thus help establish habits conducive to weight loss.”
β-glucan content of the oatmeal, a viscous fiber, seems to result in the high satiety index of oatmeal. Its important to note that the oatmeal be as unprocessed as possible, for example muesli is only half as satisfying as oatmeal using the satiety index.
The Satiety Index of foods was developed by Susanna Holt PhD, and associates at the University Of Sydney. It adds a further refinement to other food indexes such as the Glycemic Index
Interestingly even though boiled potatoes are high on the Glycemic Index they are also the highest food on the Satiety Index. Meaning that if you fill up on them (note, not fries) you will stay full for a long time and therefore eat less. If you eat them with other foods, you will eat less.

The Pima Paradox also shows how a high Satiety Index can greatly alter a high Glycemic Index score.
Whereas the Pima Indians have a significant genetic propensity toward diabetes which manifests in those consuming (in Arizona) a modern diet of plentiful refined carbohydrates, animal fat and protein. Their traditional diet (still consumed in Mexico) however comprises large amounts of corn and potatoes as well as activity, resulting in lean body mass and rare incidence of hyperinsulinemia, obesity and type 2 diabetes (NIDDM).

While caffeine has been demonized by CAM practitioners for decades an increasing number of studies are supporting tea and coffee consumption in moderated daily quantities (even in some studies what would generally be considered excessive consumption). Coffee which contains numerous flavonoids, chlorogenic acid and the antioxidant caffeine, has been shown to to reduce incidence of several diseases and support healthy brain function.
A study conducted at the University of South Florida and the University of Miami involving 124 people aged 65 to 88 was published 6/5/12 in the Journal Of Alzheimer’s Disease. It showed that those individuals with the highest blood caffeine levels actually avoided conversion of mild memory impairment to Alzheimers disease in the 2 to 4 year period in which the study was conducted.
“These intriguing results suggest that older adults with mild memory impairment who drink moderate levels of coffee — about 3 cups a day — will not convert to Alzheimer’s disease — or at least will experience a substantial delay before converting to Alzheimer’s,” said study lead author Dr. Chuanhai Cao, a neuroscientist at the USF College of Pharmacy and the USF Health Byrd Alzheimer’s Institute. “The results from this study, along with our earlier studies in Alzheimer’s mice, are very consistent in indicating that moderate daily caffeine/coffee intake throughout adulthood should appreciably protect against Alzheimer’s disease later in life.”
The following article published by the Life Extension Foundation, an integrative medicine research organization, outlines the numerous health benefits of coffee –
- Decaffeinated and caffeinated coffee lowered the risk of kidney stones in women by 9 and 10%, respectively.
- Caffeinated coffee reduced the incidence of gallstones and gall bladder disease in both men and women.
- Scientists found that coffee boosted regular weight loss by 8 pounds and promoted body fat metabolism.
- Sometimes-inconsistent findings have generally linked coffee drinking with reduced all-cause mortality and cardiovascular mortality.
- For athletes, caffeine reduced muscle pain, increased energy (ergogenic aid), and enhanced endurance.
- One study found caffeine, taken 2 hours before exercise, prevented exercise-induced asthma.
- Confirming earlier research, a 2011 study on over 50,000 women found that 4 cups of coffee daily lowered the risk of depression by 20%, compared to coffee abstainers.
- Antibacterials in coffee were found to inhibit plaque formation and prevent dental decay.
- Whether caffeinated or decaffeinated, coffee consumption prevents constipation and – despite the myth that coffee dehydrates the body – contributes to the body’s fluid requirements.
- Caffeine is believed to boost by 40% the effectiveness of pain relievers against headaches. Caffeine also helps the body absorb headache medications more quickly.
A large, as-yet-unpublished study presented October 24, 2011, found that men and women with the highest coffee consumption have a 13% and 18% lower risk, respectively, for basal cell carcinoma (a type of skin cancer).129
The May 14, 2011, issue of Breast Cancer Research reported that postmenopausal women who consumed 5 cups of coffee daily exhibited a 57% decrease in their risk of developing ER-negative
A promising study appeared in the June 8, 2011, issue of the Journal of the National Cancer Institute. The research team reported that men who drank over 6 cups of coffee a day had an 18% lower risk of prostate cancer – and a 40% lower risk of aggressive or lethal prostate cancer.
A 2009 meta-analysis in the Annals of Internal Medicine combined data on over 450,000 people and found that every additional cup per day of caffeinated or decaffeinated coffee lowered the risk of diabetes by 5 to 10%.
Caffeinated coffee has also been associated with protection against Parkinson’s disease, the second most common neurodegenerative disorder after Alzheimer’s. A study of 29,000 individuals found that one to four cups daily decreased the risk of Parkinson’s by 47% and 5 or more cups decreased the risk by 60%.
Many epidemiological studies show that the risk of diabetes drops directly according to the amount of coffee consumed. For instance, scientists found that overall risk is reduced by:
- 1. 13% with one cup a day
- 2. 47% with 4 cups a day,
- 3. 67% with 12 cups a day.
It’s noted that most of the benefits outlined are available with decaffeinated coffee as well. Also for many people coffee is the major or only source of polyphenols in the diet so those consuming a whole foods largely plant-based diet will already likely have significant reduction in incidence of diseases mentioned above. It’s also difficult to deduce which of the 1,000 phytochemicals contained in coffee are responsible for improved health though chlorogenic acid and caffeine may have significant play in neurodegenerative disorders.
