Research Question:
There is a constant speculation about the association between the metabolic syndrome and colorectal neoplasia, but the published results are contradictory. It was therefore carried out this review article.

The metabolic syndrome increases the chance of getting colorectal neoplasia?

Study Design:
This overview article contained 18 studies (case-control and cohort studies) from January 1980 to July 2011.

Results and conclusions:
The researchers found in 18 studies that the metabolic syndrome the chance of getting colorectal neoplasia significantly with 34% [95% CI = 1.24-1.44] increased. Significant is, there is a link at a 95% reliability.

The researchers found in case-control studies that the metabolic syndrome the chance of getting colorectal neoplasia significantly with 58% [95% CI = 1.44-1.73] increased.

The researchers found in cohort studies that the metabolic syndrome the chance of getting colorectal neoplasia significantly with 21% [95% CI = 1.13-1.29] increased.

The researchers found that the metabolic syndrome the chance of getting colorectal cancer significantly with 30% [95% CI = 1.18-1.43] increased.

The researchers found that the metabolic syndrome the chance of getting Colorectal carcinoma significantly with 37% [95% CI = 1.26-1.49] increased.

The researchers found in the subgroup analysis (to get more information) that the Association was significant in both men and women.

The researchers concluded that the metabolic syndrome the chance of getting colon cancer (colorectal cancer) increased.

In cancer it is referred to as malignant neoplasia. Neoplasia is cancer is malignant neoplasm and malignant tumor. Cancer can arise from malignant tumor.

The metabolic syndrome is a condition that consists of a cluster of risk factors for the onset of heart disease. These risk factors are abdominal obesity (large waist dimension), high blood pressure, elevated triglycerides, Hyperglycemia and reduced HDL-cholesterol levels. If a person has 3 or more of these risk factors, there has been talk of the metabolic syndrome.

Research Question:
Previous studies showed inconsistent findings regarding the link between a high plasma homocysteine levels and abdominal aortic aneurysm (AAA). It was therefore carried out this review article.

Increases the chances of getting a high plasma homocysteine levels of abdominal aortic aneurysm?

Study Design:
This overview article contained 7 case-control studies with 6445 participants, of which 1410 patients with abdominal aortic aneurysm.

There was no question of publication bias.

Results and conclusions:
The researchers found that an increased plasma homocysteine levels the chance of getting an abdominal aortic aneurysm significantly with 229% [95% CI = 1.66-6.51, I2 = 92.9%, p = 0.000] increased.

The researchers found that an increased plasma homocysteine levels the chance of getting an abdominal aortic aneurysm in men non-significant with 136% [95% CI = 0.63-8.82] increased.

The researchers concluded that a high plasma homocysteine levels the chance of getting an abdominal aortic aneurysm probably increased. Probably because this overview article contained only case-control studies and also knew heterogeneity.

Conclusion found in case-control studies is not really reliable because case-control studies very sensitive to errors, which can affect the conclusion. Therefore, the conclusion be confirmed in case-control studies found in cohort studies or in RCTs. Read more study design.

An abdominal aortic aneurysm is a local dilation of the abdominal aorta. An abdominal aortic aneurysm is defined as an aortic diameter of at least one and a half times the diameter measured at the level of the renal arteries. A Dilated abdominal aorta can tear after which the patient can bleed to death within minutes.

• Risk factors of abdominal aortic aneurysm:
• Diabetes mellitus (diabetes)
• Heredity
• Hypercholesterolemia (high cholesterol)
• Hypertension (high blood pressure)
• Age (> 50)
• Men are more likely than women
• Smoking

Research Question:
The total homocysteïneconcentraties during pregnancy are associated with a wide range of unwanted pregnancy outcomes and may possibly affect the birth weight.

Should women during pregnancy on their homocysteine levels look for?

Study Design:
This overview article contained 19 Rcts with 21326 participants.

Results and conclusions:
The meta-analysis showed a crude OR of 1.25 [95% CI = 1.09-1.44] see. By the crude OR as a linear effect to express it came in line with a decrease in the birth weight of 31 grams (95% CI =-13 to-51 grams) at a 1-SD increase in maternal homocysteine levels.

The researchers concluded that women who during pregnancy a high homocysteine levels had an elevated risk of getting an SGA baby or a baby with a low birth weight. The small estimated birth weight difference would have little clinical relevance to individual newborn but it would be of greater importance, however, are on the population level.

• Homocysteine is a non-essential sulphur-containing amino acid. The name is based on the fact that it is a homologue of cysteine. A non-essential amino acid is, the amino acid that the body itself can produce.
  Amino acids are building blocks of proteins.
• Homocysteine occurs in the metabolism of proteins by the essential amino acid methionine.
• Homocysteine is labeled by the WHO as a risk factor for heart disease.
• Homocysteine makes heart endothelial cells more susceptible to inflammatory mediators and can directly cause cell death.
• An increased homocysteine levels can be caused by genetic defects, but also by a shortage of folic acid, vitamin B6 and B12.
• At least 200 micrograms (mcg) folic acid is a day to avoid a high homocysteine levels.
• Homocysteine can be measured in blood and urine. In blood is it for about 70% bound to plasma proteins.
• Homocysteine levels can only be determined when someone 12 hours has not eaten or drunk (sober).
• The normal homocysteine levels in the blood is about 13-14 µmol/l for men and 12-13 µmol/litre for women.
  However, an optimal level is 7.5. A homocysteine level above the 15 µmol/l is too high.
• With the rising of the age, the "normal" homocysteine levels far: with such a 5 to 10% every 10 years.
• What factors increase homocysteine levels?
  • hyperhomocysteinemia. In about 10% of the persons in whom a hyperhomocysteinemia is found, there appears to be a hereditary cause.
  • Smoking (smoking inactivates vitamin B12)
  • alcohol
  • elevated cholesterol levels
  • a deficiency of vitamin B6, B12 and/or folic acid
  • gluten-sensitivity
  • bowel problems
  • genus. Men have a slightly higher homocysteine levels than women.
• The most effective way to reduce homocysteine levels is through folic acid supplements.
  Vitamin B12 reduces very light homocysteine levels.
• Via folic acid supplements can homocysteine levels by an average of 25% be lowered.
  The effective dose of folic acid supplements is between 200-800 micrograms per day.
• It is through power supply not possible to 400 micrograms (mcg or µg) folate to get inside. Thus lowering homocysteine levels through food supplements.
• The increased homocysteine levels (> 15 µmol/l) cannot be lowered with vitamin B6.

Homocysteïneverlagende meals (at least 200 micrograms (mcg) folic acid):

• Spinach dish with egg and cheese for 4 people
• Krieljes with roasted Brussels sprouts and pecans for 4 people
• Sweet potatoes with salmon and spinach for 4 people

Scientific studies on the relationship between high homocysteine levels and health:
The review articles of randomized, placebo-controlled double-blind human studies (Rcts) answer the following question:
"Is swallowing food supplements make sense?". Yes at a positive conclusion and no in the case of a negative conclusion.

The review articles of cohort studies or case-control studies answer the following question:
"Should I change my diet?".

1. Low vitamin B12 levels increases age-related macular degeneration
2. 5 mg folic acid per day for a minimum of 4 weeks reduces homocysteine levels of patients with coronary heart disease
3. A high plasma homocysteine levels increases probably abdominal aortic aneurysm
4. Folic acid supplements lower homocysteine levels in people with type 2 diabetes
5. Maternaal a high homocysteine levels increases the chances of SGA baby

The two most common hereditary forms of colon cancer are familial adenomatous Polyposis (FAP) and the Lynch syndrome (previously Hereditary Non-Polyposis Colorectal carcinoma (HNPCC) called). FAP and the Lynch syndrome are responsible for about 5 to 10% of all cases of colon cancer. Characteristic of these hereditary forms of colon cancer is that they are usually at a young age (for the 50th year of life) originated. Hereditary predisposition does not mean someone will certainly get colon cancer. Carriers of the Lynch syndrome have an increased risk of inherited by one of their parents (25-70%).

Colon cancer (not hereditary form) is mainly found in people of 60 years of age and older. But colon cancer can also occur on (much) younger age.

The Minister of health, welfare and Sport has decided to starting from 2014 a rural population screening for colon cancer to enter. The introduction of the population screening means that from 2014 all Dutch people between 55 and 75 year get a call every two years to surrender to defecate. This is checked for traces of blood. Traces of blood in the stool may indicate colon cancer but doesn't have to be that way.

At an early detection of colon cancer survives 90% of patients the first 5 years. But when colon cancer a chance to sow out to other organs, then only 10% survive the first five years.

The growth of colon cancer usually goes very slowly. It may take up to ten years a healthy cell eventually a cancer cell.

There is no single cause for the emergence of non-hereditary colon cancer.

Scientific studies on colon cancer:
The review articles (meta-analyses) of randomized, placebo-controlled double-blind human studies (Rcts) answer the following question:
"Is swallowing food supplements make sense?". Yes at a positive conclusion and no in the case of a negative conclusion.

Research Question:
Eating mushrooms lowers the chance of getting breast cancer?

Study Design:
This overview article contained 8 case-control studies (2313 cases and 2387 controls) and 2 cohort studies (4577 cases and 1748623 persons years).

There was no question of publication bias.

Results and conclusions:
The researchers found in a dose-dependent analysis linear relationship between eating mushrooms and the reduced risk of getting breast cancer.

The researchers found that eating every ounce mushrooms per day, the chance of getting breast cancer significantly with 3% [RR = 0.97, 95% CI = 0.96-0.98, I2 = 56.3%, p = 0.015] reduced.

The researchers found that eating mushrooms the risk of getting breast cancer among premenopausal women significantly with 4% [RR = 0.96, 95% CI = 0.91-1.00, I2 = 79.1%, p = 0.008] reduced.

The researchers found that eating mushrooms the risk of getting breast cancer among postmenopausal women significantly with 6% [RR = 0.94, 95% CI = 0.91-0.97, I2 = 0%, p = 0.408] reduced.

The researchers concluded that eating mushrooms reduced the chance of getting breast cancer.

Research Question:
Observational studies suggest a link between fiber intake and the risk of getting type 2 diabetes, but the results are inconsistent. Therefore, this review article was carried out.

Eating fiber reduces the chances of getting diabetes type 2?

Study Design:
This overview article contained 17 prospective cohort studies with 488293 participants, of which 19033 people with diabetes type 2.

Results and conclusions:
The researchers found that eating total fibers, corn fiber, fruit fiber and insoluble fiber, the chance of getting type 2 diabetes significantly with respectively 19% [95% CI = 0.73-0.90], 23% [95% CI = 0.69-0.85], 6% [95% CI = 0.88-0.99] and 25% [95% CI = 0.63-0.89] reduced.

The researchers found a non-linear relationship between eating (total) fibers and getting diabetes type 2, with a non-significant reduced risk of 2% at 15 grams per day, a non-significant reduced risk of 3% at 20 grams per day, a significantly reduced risk of 11% at 25 grams per day, a significantly reduced risk of 24% at 30 grams per day and a significantly decreased risk of 34% at 35 grams per day.

The researchers found that every increase of 2 grams of corn fiber a day, the chance of getting type 2 diabetes significantly with 6% [RR = 0.94, 95% CI = 0.93-0.96] reduced.
Significant is, there is a link at a 95% reliability.

The researchers concluded that eating fiber (at least 25 grams a day) the chances of getting diabetes type 2 reduced. The reduced risk was non-linear.

• Dietary fiber, also called "ballast substances", is a collection of substances not be digested in the small intestine. They come so unchanged in the colon where they exert positive effects on the body.  
• Dietary fiber or fibers are chemically carbohydrates that give firmness to plants.
• Dietary fiber do not occur in animal products. They come only in plant products, such as vegetables, fruits and nuts for.
• Dietary fiber do not provide nutrients to the body but they are important for proper bowel function.
• There are 2 types of dietary fiber:
  1. Non-fermentable dietary fiber, also known as insoluble fiber called. Insoluble fiber works like a sponge in the colon: they take on moisture. As a result, hard, dry stool soft and supple. Loose stools is referred to by the sponge effect just thickened. Non-fermentable dietary fiber give a longer satiety.
     Insoluble fiber are especially in whole grain and grain products, such as whole wheat bread, brown bread, muesli, Granola, oatmeal and bran.
     Examples of non-fermentable fibers are: resistant starch, hemi-cellulose, cellulose and lignin.
  2. Fermentable dietary fiber, also known as soluble fiber called. Fermentable dietary fiber also take water on, albeit less than the non-fermentable fibers. They are mostly well water soluble and also bind bile acids, glucose, cholesterol and fatty acids to itself. They are broken down by intestinal bacteria in the large intestine. The short-chain fatty acids, substances that promote the release, such as bowel function.
     Fermentable fibers occur mainly in vegetables, fruits and legumes.Non-fermentable dietary fiber give a longer satiety, while fermentable dietary fibers promote bowel function.
• In food, these 2 types of fiber next to each other. In one product are more soluble fiber than insoluble and vice versa.
• Dietary fiber that serve as food for the good intestinal bacteria in the colon, are called Prebiotics. Prebiotics are fermentable fibers.
• The EFSA has adopted no health claims of Prebiotics in 2013.
  In the year 2013 is not punishable by law approved health claims of Prebiotics on food packaging and food supplements to put.
• The most well-known Prebiotics are:
  • Inulin (is to high fiber white bread added).
  • Fructo-oligosaccharides (FOS to baby food as CIS and added).
  • Pectins (as thickening agents added to soft drinks).
  • Glucans from grain products.
• Dietary fiber supply per gram 2 kcal.
• Dietary fiber in the food industry are often used as thickening agents such as pectin and gums. Thickening agents for food law E-numbers.
  Thickening agents improve the mouthfeel of diet drinks and sugar-free soft drinks.
• A high-fiber diet is a diet with a minimum of 1.5 grams of fiber per 100 kcal.
• Recommendations of dietary fiber:
  • 25-30 grams of dietary fiber per day.
    25 grams of dietary fiber per day corresponds to a daily diet with at least 1.3 grams of fiber per 100 kcal and 30 grams of fiber corresponds to a minimum of 1.5 grams of fiber per 100 kcal.
  • The minimum limit for the fiber intake for children over 2 years is "the age + 5" g and the maximum intake is "the age + 10" g.
  • Still no specific recommendation for soluble and insoluble dietary fibre.

Scientific studies on dietary fiber:
The review articles (meta-analyses) of randomized, placebo-controlled double-blind human studies (Rcts) answer the following question:
"Is swallowing food supplements make sense?". Yes at a positive conclusion and no in the case of a negative conclusion.

2. 10 grams of fiber a day reduces death from heart disease
3. 10 grams of fiber a day lowers total mortality
4. At least 25 grams of fiber a day lowers diabetes type 2
5. Fiber intake through feeding lowers possible stroke
6. Standard diabetes type 2 patients benefit from fiber intake
7. Dietary fiber provide protection against breast cancer
8. A diet with plenty of fiber and dairy products and less refined grains, meat and sugar-rich foods and drinks lowers body weight

Research Question:
Epidemiological studies have reported an inverse association between the frequency of nut consumption and BMI and the risk of obesity. However, clinical studies on the relationship between nut consumption and overweight are scarce and unconvincing. It was therefore carried out this review article.

Increases the risk of overweight eating lots of nuts?

Study Design:
This overview article contained 33 clinical trials.

There was no question of publication bias.
This meta-analysis used the weighted average difference and the random-effects model.

Results and conclusions:
The researchers found that a diet high in nuts compared with little nuts, the weight does not significantly with 0.47 kg [95% CI =-1.17 to 0.22 kg, I2 = 7%] reduced.
Not significant is, there can not be said with 95% reliability that a diet high in nuts with 0.47 kg reduced the weight really.

The researchers found that a diet high in nuts compared with little nuts, the BMI is not significant with 0.40 point [WMD =-0.40 kg/m (2), 95% CI =-0.97 to 0.17 kg/m (2), I2 = 49%] reduced.
Not significant is, there is no link to a 95% reliability.

The researchers found that a diet high in nuts compared with little nuts, the waist circumference not significant with 1.25 cm [WMD =-1.25 cm, 95% CI =-2.82 to 0.31 cm, I2 = 28%] reduced.

The researchers concluded that a diet high in nuts the chance of getting overweight not raised or lowered.

Conclusions of studies with a larger number of patients or with a better methodological quality are more reliable than studies with a smaller number of patients or with poor methodological quality.
The weighted mean difference (WMD) is the result of a meta-analysis of the pooled and weighted results of studies with continuous outcomes (including averages and standard deviations).

Research Question:
Inconsistent results with regard to the relationship between eating fish and the risk of getting various forms of esophageal cancer, such as esophageal squamous cell carcinoma and esophageal adenocarcinoma are found in scientific studies. It was therefore carried out this review article.

Eating fish reduces the chance of getting esophageal cancer?

Study Design:
This overview article contained 21 3 cohort studies and case-control studies.

Results and conclusions:
The researchers found that eating a lot of fish compared with little fish, the chance of getting of esophageal squamous cell carcinoma significantly with 19% [95% CI = 0.66-0.99 and there was heterogeneity between the studies, p = 0.007] reduced.

In the highest versus the lowest analysis the researchers found that eating fish the chance of getting esophagus adenocarcinoma non-significant 14% [95% CI = 0.61-1.22] reduced. Non-significant is, there cannot be said with 95% reliability that eating a lot of fish the chance of getting esophagus adenocarcinoma reduced.

Esophageal cancer is a malignant tumor in the esophagus. There are two types of esophageal cancer:

1. Esophagus squamous cell carcinoma: this tumor forms from the layer of cells that line the inside of the esophagus and arises especially in the middle and lower part of the esophagus.
2. Esophagus adenocarcinoma: this tumor develops from cylindrical epithelium, also called Barrett epithelium called.

The Dutch recommendation for fish consumption is fish twice a week (100-150 grams at a time), including at least 1 time oily fish. Fat fish have more EPA and DHA than not fat fish.
 

Research Question:
Long chain polyunsaturated fatty acids (LC-PUFA) would be beneficial in preventing pancreatic cancer, but the relationship between the consumption of fish or LC-PUFA and pancreatic cancer found in epidemiological studies is controversial and inconclusive. It was therefore carried out this review article.

Eating fish or LC-PUFA lowers the chances of getting pancreatic cancer?

Study Design:
This overview article contained 9 cohort studies with 1209265 participants, of which 3082 people with pancreatic cancer and an average follow-up period of 9 years. This review article also contained further 10 case-control studies with 2514 patients with pancreatic cancer and 18779 controls (people without pancreatic cancer).

Results and conclusions:
The researchers found in 8 cohort studies that compared with the lowest fish consumption, the highest fish consumption the chance of getting pancreatic cancer non-significant with 2% [RR = 0.98, 95% CI = 0.86-1.12] reduced. Non-significant is, there is no link.

The researchers found in 9 cohort studies that compared with the lowest fish consumption, the highest fish consumption the chance of getting pancreatic cancer non-significant 4% [RR = 0.96, 95% CI = 0.76-1.21] reduced. Non-significant is, there is no link.

Similar results were also found for LC-PUFA in 4 cohort studies and case-control studies 2.

The researchers concluded that there is no link existed between eating fish or LC-PUFA and the chance of getting pancreatic cancer.

Lowers eating n3-fatty acids the chances of getting breast cancer?

Study Design:
This overview article 26 contained articles that 21 prospective cohort studies (20905 883585 participants, of which people with breast cancer).

11 articles on visinname (13323 with breast cancer patients and 687770 participants), 17 articles on maritime n3-fatty acids intake (16178 with breast cancer patients and 527372 participants) and 12 articles on alpha-linolenic acid intake (with 56811 breast cancer patients and 405592 participants).

There was no question of publication bias.

Results and conclusions:
The researchers found that eating a lot of n3 fatty acids of maritime origin compared to little, the chance of getting breast cancer significantly with 14% [95% CI = 0.78 to 0.94, I2 = 54%] reduced.
The reduced risk remained the same, regardless of whether the n3-fatty acids of maritime origin was measured via the questionnaires [RR = 0.85, 95% CI = 0.89-0.96, I2 = 67%] or via tissue biomarkers (RR = 0.86, 95% = 0.71-1.03, I2 = 8%].

The researchers found that the reduced risk in subgroup analyses between the n3-fatty acids of maritime origin and getting breast cancer was clearer in studies where not corrected was BMI [RR = 0.74, 95% CI = 0.64-0.86, I2 = 0%] than in studies involving corrected was BMI [RR = 0.90, 95% CI = 0.80-1.01, I2 = 63.2%].

The researchers found that every increase of 0.1 grams of n3 fatty acids of maritime origin per day, the chance of getting breast cancer significantly with 5% [95% CI = 0.90-1.00, I2 = 52%] reduced.

The researchers found that every increase of 0.1 grams of alpha-linolenic acid per day, the chance of getting breast cancer is not significantly with 1% [95% CI = 0.98-1.01] reduced.  

The researchers found that both eating only EPA [RR = 0.93, 95% CI = 0.85-1.02] as DHA [RR = 0.88, 95% CI = 0.75-1.03] the chance of getting breast cancer are not significantly reduced. Not significant is, there is no link to a 95% reliability.

The researchers found that every increase of 15 grams of fish per day, the chance of getting breast cancer is not reduced or increased [RR = 1.00, 95% CI = 0.97-1.03].

The researchers concluded that eating a lot of n3-fatty acids (at least 0.1 grams per day) of maritime origin (so not plant origin) reduced the chance of getting breast cancer.

Research Question:
The intake of EPA and DHA lowers blood pressure?

Study Design:
This overview article contained 70 RCTs. The average study duration was 69 days and the average intake of EPA and DHA was 3.8 grams per day.

Results and conclusions:
The researchers found that the intake of EPA and DHA (through diet and supplements) the systolic blood pressure (systolic blood pressure) significantly with 1.52 mmHg [95% CI =-2.25 to-0.79] reduced.

The researchers found that the intake of EPA and DHA (through diet and supplements) the diastolic blood pressure (underpressure) significantly with 0.99 mmHg [95% CI =-1.54 to-0.44] reduced.

The researchers found that the intake of EPA and DHA systolic blood pressure among people with high blood pressure significantly with 4.51 mmHg [95% CI =-6.12 to-2.83] reduced.

The researchers found that the intake of EPA and DHA the diastolic blood pressure among people with high blood pressure significantly with 3.05 mmHg [95% CI =-4.35 to-1.74] reduced.

The researchers found that the intake of EPA and DHA systolic blood pressure among people with normal blood pressure significantly with 1.25 mmHg [95% CI =-2.05 to-0.46] reduced.

The researchers found that the intake of EPA and DHA the diastolic blood pressure among people with normal blood pressure significantly with 0.62 mmHg [95% CI =-1.22 to-0.02] reduced.

The researchers found that swallowing of EPA and DHA supplements the systolic blood pressure significantly with 1.75 mmHg [95% CI =-2.55 to-0.94] and the diastolic blood pressure significantly with 1.11 mmHg [05% CI =-1.72 to-0.50] reduced.

The researchers found that the intake of EPA and DHA (through diet and supplements) to 2 grams per day systolic blood pressure significantly with 1.81 mmHg [95% CI =-3.59 to-0.03] and 3-4 grams per day with 3.85 mmHg [95% CI =-5.55 to-2.15] reduced.

The researchers found that the intake of EPA and DHA (through diet and supplements) to 2 grams per day the diastolic blood pressure non-significant reduced. However, 2 to 3 grams per day reduced the diastolic blood pressure significantly with 1.09 mmHg [95% CI =-2.08 to-0.11 and 3 to 4 grams per day with 1.86 mmHg [95% CI =-2.67 to-1.06].

The researchers concluded that the intake of more than 2 grams of EPA and DHA (through diet and supplements) per day reduced both systolic and diastolic blood pressure, particularly among people with high blood pressure that no blood pressure lowering medications.

Research Question:
Observational studies of the relationship between the consumption of witvlees (including fish and poultry) and the risk of getting colorectal adenoma, the precursor to colon cancer, showed mixed results. It was therefore carried out this review article.

Lowers eating witvlees (including fish and poultry) the chance of getting colorectal adenoma?

Study Design:
This overview article contained 16 case-control studies and cohort studies 5 until april 2012.

Results and conclusions:
The researchers found that eating a lot of witvlees compared to little, the chance of getting colorectal adenoma non-significant 4% [95% CI = 0.84-1.09] reduced. Non-significant is, there is no link to a 95% reliability.

The researchers found that eating a lot of fish compared to little, the chance of getting colorectal adenoma with insignificant 2% [95% CI = 0.80-1.19] reduced. Non-significant is, there is no link to a 95% reliability.

The researchers found that eating a lot of poultry compared with little, the chance of getting colorectal adenoma with insignificant 2% [95% CI = 0.80-1.18] reduced. Non-significant is, there is no link to a 95% reliability, or in other words, there cannot be said with 95% reliability that eating a lot of poultry reduces the chance of getting colorectal adenoma.

The researchers concluded that eating a lot of witvlees (including fish and poultry) the chance of getting colorectal adenoma not reduced.

Research Question:
Lowering eating fish and swallowing fish oil supplements the chance of getting heart disease?

Study Design:
This overview article contained 26 prospective cohort studies and 12 Rcts. This 38 studies gave participants 800000 together, spread over 15 countries. There was limited evidence of publication bias and heterogeneity between the studies or within the subgroups.

Results and conclusions:
The meta-analysis of cohort studies showed that people who ate fish 2-4 servings per week, significant 6% less likely walked on getting heart disease than people who ate fish 1 serving or less per week. The combined relative risk was 0.94 [95% CI = 0.90-0.98]. Significant is, it can be said with 95% reliability that the decline of 6% was really due to eating fish.

The meta-analysis of cohort studies showed that people who ate 5 or more servings of fish per week, significant 12% less chance ran on getting heart disease than people who ate 1 serving of fish per week. The combined relative risk was 0.88 [95% CI = 0.81-0.96].

The meta-analysis of Rcts with primary prevention heart disease as outcome showed that swallowing fish oil supplements the chance of getting heart disease non-significant with 2% [95% CI = 0.89-1.08] reduced. Not significant is, it cannot be said with 95% reliability that the decline of 2% was due to really swallowing fish oil supplements.

The meta-analysis of Rcts with secondary prevention of heart disease as outcome showed that swallowing fish oil supplements the chance of getting heart disease non-significant 17% [95% CI = 0.99-1.38] increased. Not significant is, it cannot be said with 95% reliability that the rise was due to the 17% really swallowing fish oil supplements.

The researchers concluded that eating fish the chance of getting heart disease reduced. However, swallowing fish oil supplements reduced the chance of getting heart disease

Additional information about El Mondo:
For years is the reduced risk of heart disease attributed to the omega-3 fatty acids EPA and DHA (the two main visvetzuren in fish oil supplements). But there is more and more scientific evidence that swallowing of EPA and DHA chances of getting heart disease not lowers. In other words, scientists are no longer convinced of the causal link between EPA and DHA and the reduced risk of cardiovascular disease.

While science is about to move away from the causal link between the omega-3 fatty acids and heart disease, the food industry about to more omega-3 fatty acids to add to its products with the claim that omega-3 fatty acids good for heart and blood vessels.

1 serving of fish is 100-150 grams.
