13 Studies on coconut oil and its health effects
Coconut oil has received much attention in recent years.
This is due to their potential health benefits , many of which are attributable to the medium chain triglycerides (MCT) containing.
There are many promising animal studies, test tube and observation coconut oil. However, these types of studies can not prove that coconut oil is beneficial in humans.
Interestingly, it has also been studied in several controlled human trials. These studies are much better in determining whether coconut oil is actually healthy for people.
This article analyzes 13 controlled human studies on coconut oil.
Studies
1. White MD, et al. " improved energy expenditure postprandial with feeding medium chain fatty acids is attenuated after 14 d in premenopausal women. " American Journal of Clinical Nutrition , 1999.
Details
Twelve normal weight women followed a diet of half-triglyceride chain (MCT) for 14 days, consuming butter and oil coconut as its main sources of fat.
for another 14 days, followed by a long chain triglycerides (LCT) diet, consumption of beef tallow as its main source of fat.
Results
After 7 days, the basal metabolic rate and calories burned after meals were significantly higher in the MCT diet, compared with the diet of the LCT. After 14 days, the difference between diets was not statistically significant.
2. Papamandjaris AA, et al. " oxidation of endogenous fat during medium chain versus long chain triglycerides feed in healthy women. " International Journal of Obesity , 2000.
Details
Twelve normal weight women ate a mixed diet either supplemented with butter and coconut oil (diet MCT) or beef tallow (diet LCT) for 6 days. For 8 days, they were given long chain fatty the two groups to assess fat burning.
Results
On day 14, the MCT group burn more body fat than the LCT group. resting metabolic rate was significantly higher on day seven in the MCT group compared to the LCT group, but the difference was already significant by day 14.
3. Papamandjaris AA, et al. " Components of total energy expenditure in healthy young women are not affected after 14 days of feeding with medium-to long-chain triglycerides. " Obesity Research , 1999.
Details
Twelve normal weight women ate a mixed diet supplemented with butter and coconut oil (diet MCT) for 14 days and tallow veal (LCT diet) for 14 separate days.
Results
resting metabolic rate was significantly higher on day seven of the MCT diet compared with the diet of the LCT, but the difference was not significant during the day 14. the total calorie expenditure was similar in both groups throughout the study.
4. Liau KM, et al. " An open space to evaluate the efficacy and safety of virgin coconut oil in reducing visceral adiposity pilot study. " Pharmacology Notices international academic research , 2011.
Details
Twenty overweight or obese consume 10 ml of virgin coconut oil three times a day before meals for four weeks, for a total of 30 ml ( 2 tablespoons) per day. They were instructed to follow their usual diets and exercise routines.
Results
After four weeks, the men had lost an average of 1.0 in (2.61 cm) and women an average of 1.2 in ( 3.00 cm) around the waist. The average loss Weight was 0.5 pounds (0.23 kg) and 1.2 generally pounds (0.54 kg) in men.
5. Assuncao ML, et al. " Effects of coconut oil in the diet on biochemical and anthropometric profiles of women presenting with abdominal obesity. " Lipids , 2009.
Details
Forty women with abdominal obesity were randomly assigned to take 10 ml of soybean oil or coconut oil at each meal, three times a day for 12 weeks. This equates to 30 ml (2 tablespoons) of coconut oil per day.
They were instructed to follow a diet low in calories and walk 50 minutes a day.
Results
Both groups lost about 2.2 pounds (1 kg). However, the coconut oil group had a 0.55-in (1.4 cm) decrease in waist circumference, while the soybean oil group had a slight increase.
The group coconut oil also had an increase in HDL cholesterol (the good cholesterol) and a decrease of 35% in C-reactive protein (CRP), a marker of inflammation.
In addition, the soybean oil group had an increase in LDL (bad cholesterol), HDL cholesterol decreased and a decrease of 14% in CRP.
6. Sabitha P, et al. " Comparison of lipid profile and antioxidant enzymes among men from southern India who consume coconut oil and sunflower oil. " Indian Journal of Clinical Biochemistry , 2009.
Details
Seventy men with type 2 diabetes and 70 healthy men were divided into groups based on the use of coconut oil compared to sunflower oil groups cooking over a period of six years. cholesterol, triglycerides and markers of oxidative stress were measured.
Results
There were no significant differences in values between groups coconut oil and sunflower oil. Diabetic men had higher markers of oxidative stress and the risk of heart disease than non-diabetic men irrespective of the type of oil used.
7. Cox C, et al. " Effects of coconut oil, safflower oil and butter in lipids and lipoproteins in people with high cholesterol levels moderately. " Journal of Lipid Research , 1995.
Details
Twenty-eight people with high cholesterol followed by three diets containing coconut oil, butter or safflower oil as the main source of fat for six weeks each. lipids and lipoproteins were measured.
Results
coconut oil and butter significantly increase HDL that safflower oil in women, but not in men. elevated total cholesterol butter over coconut oil or safflower oil.
8. R Reiser, et al. " plasma lipid and lipoprotein response of humans to meat, fat coconut oil and safflower oil. " American Journal of Clinical Nutrition , 1985.
Details
Nineteen men with normal cholesterol levels consumed lunch and dinner containing three different greases for three periods of sequential test.
They consume coconut oil, safflower oil and beef fat for five weeks each, alternating with the normal diet for five weeks between each test period.
Results
The diet of coconut oil increased the total, HDL and LDL cholesterol more diets oil fat meat safflower, but triglycerides raised under diet containing beef fat.
9. Muller M, et al. " The / HDL serum LDL cholesterol is more influenced favorably by saturated fat exchange not saturated by reducing saturated fats in the diet of women. " Journal of Nutrition 2003.
Details
Twenty-five women consumed three diets: rich in fat, the diet of coconut oil; a diet low in fat, coconut oil base; and diet of highly unsaturated fatty acids (HUFA).
They consume each for 20-22 days, alternating with one week of their normal diet between each test diet period.
Results
The high-fat diet group based coconut oil had a greater increase in HDL and LDL cholesterol than other groups.
The low fat, diet group based coconut oil showed an increase of LDL to HDL, while other groups showed decreased.
10. Muller M, et al. " A diet rich in coconut oil reduces diurnal postprandial variations in the circulation of tissue activator antigen plasminogen and fasting lipoprotein (a) compared with a diet rich in unsaturated fats in women. " Journal of Nutrition , 2003.
Details
Eleven women consumed three different diets: one rich in fat, diet base coconut oil; a diet low in fat, coconut oil base; and a diet with highly unsaturated fatty acids mostly.
were followed each diet for 20-22 days. Then alternate with 1 week of a normal diet between test periods.
Results
Women who consumed the high-fat, diet of coconut oil had the greatest reductions in markers of inflammation after meals and fasting markers risk of heart disease, especially compared with the group of HUFA.
11. Kaushik M, et al. " The effect of coconut oil pulling Streptococcus mutans in saliva count compared with chlorhexidine mouthwash. " Journal of Contemporary Dental Practice , 2016.
Details
Sixty people were randomized to rinse your mouth with coconut oil for 10 minutes, mouthwash of chlorhexidine for a minute or distilled water for one minute. The forming plate bacteria in the mouth were measured before and after treatment.
Results
Both coconut oil and chlorhexidine are found to significantly reduce the amount of plaque forming bacteria in saliva.
12. Peedikayil FC, et al. " Effect of coconut oil related gingivitis plaque. - A preliminary report " Niger Medical Journal , 2015.
Details
Sixty adolescents aged 16-18 with gingivitis (gum inflammation) had oil with coconut oil pulling for 30 days. Inflammation markers and plate were measured after seven, 15 and 30 days.
Results
The markers of plaque and gingivitis was significantly reduced by day seven continued to decline during the study period.
However, there was no control group in this study, so we can not conclude that the benefits were caused by coconut oil.
13. Law KS, et al. " The effects of virgin coconut oil (VCO) as supplementation on quality of life (QOL) of patients with breast cancer. " Lipids Disease Health Journal 2014.
Details
Sixty women with advanced breast cancer receiving chemotherapy in this study. They were randomized to receive either 20 ml of virgin coconut oil daily or no treatment.
Results
Women in the group coconut oil had better scores of quality of life, fatigue, sleep , loss of appetite body image, sexual function and the control group.
Effects on weight loss and metabolism
All five studies that examine changes in fat loss or metabolism found some benefit with coconut oil, compared to other oils or control groups. However, the effects were generally modest.
Here are some facts to consider:
- Coconut oil increased metabolism for at least one point of time in each study that was measured ( 1 2 3 ).
- In one study, subjects in the group coconut oil experienced decreases in body fat and waist circumference without reducing calories intentionally ( 4 ).
- A study that compares calorie-restricted diets found abdominal fat decreased only in the group taking coconut oil ( 5 ).
There are also several studies analyzing fat loss and metabolic changes in response to MCT oil, which makes up about 65% of coconut oil.
In each of these studies, MCT oil was found to increase metabolism reduce appetite and caloric intake and promote fat loss ( 6 7 8 9 10 11 12 ).
Here is a detailed report on the effects of coconut oil Article about the weight and belly fat .
effects on cholesterol, triglycerides and inflammation
Five studies examined the effects of different fats on cholesterol and triglycerides. Here are some points about the results:
- Coconut oil increases HDL cholesterol than saturated fat not made and at least as much as butter ( 5 , 13 14 15 ). found
- Coconut oil to raise the total cholesterol and LDL over safflower oil and beef fat, but less than soybean oil and butter ( 5 , 13 14 ).
- Triglycerides did not change much in response to coconut oil over other oils in diets containing similar fat.
- markers of inflammation and oxidative stress decreased more in people who consumed coconut oil compared to people who consumed other oils. [19459045 ( 5 16 )]
Unfortunately, the studies do not look ApoB or particle count LDL , which are more accurate markers for the risk of heart disease than LDL cholesterol measurement standard.
Other health benefits of coconut oil
Dental Health
found that the oil practice shooting with coconut oil to reduce bacteria responsible for license plate. In addition, significantly it improved gingivitis in adolescents.
Quality of life in breast cancer
The addition of a small amount of coconut oil to the diet of women undergoing chemotherapy for breast cancer resulted in significantly better quality of life scores.
Take Home Message
Coconut oil appears to help overweight people lose abdominal fat . Also it appears to increase metabolic rate, at least temporarily.
However, because each tablespoon of coconut oil provides 130 calories, this increase in metabolism can be easily compensated if large amounts are consumed.
Although coconut oil appears to increase LDL cholesterol over some other fats, their most consistent effect is an increase in HDL cholesterol.
is also important to remember that responses to dietary fats can vary greatly from one person to another.
That said, coconut oil is a general food healthy and naturally. Including in your diet can improve your health, weight and quality of life.
