• Children under 4 years.
• Postoperative patients.
• Patients with impaired immunity (Aids patients, patients with immunosuppressive drugs, such as Crohn's disease or rheumatism).

Research Question:
A low sodium intake will lower blood pressure?

Study Design:
This overview article contained 14 cohort studies and 5 Rcts that mortality, cardiovascular heart disease, stroke or coronary heart disease had as outcome measures and 37 Rcts that blood pressure, the functioning of the kidneys, the blood fats and the catecholamineconcentratie had as outcome measures. This review article also contained further 9 Rcts and 1 cohort study that blood pressure in children as outcome measure (= end point of the study) had.  

The Rcts had a follow up to 4 weeks to 36 months (most (n = 31) less than 3 months) with 5508 participants and used 24-hour urine to measure the sodium intake. The difference in the sodium intake between the intervention and control group amounted to 40 mmol/day (920 mg) or more.
The cohort studies had a follow-up of at least 1 year.

The funnel plots showed a low risk of publication bias see.

Results and conclusions:
The researchers found that in adults decreased in 36 Rcts carried out sodium intake the systolic blood pressure significantly with 3.39 mmHg [95% CI = 2.46-4.31] and vacuum significantly with 1.54 mmHg [95% CI = 0.98-2.11] reduced. Significant is, there is a link at a 95% reliability.

The researchers found that a sodium intake of 2 grams or more (equivalent to 5 grams of salt or more) per day compared to less than 2 grams per day, the systolic blood pressure significantly with 3.47 mmHg [95% CI = 0.76-6.18] and vacuum significantly with 1.81 mmHg [95% CI = 0.54-3.08] reduced.

The researchers found in mature that a reduced sodium intake no significant, adverse effects on blood fats, the functioning of the kidneys and catecholamineconcentratie [p > 0.05] had.

The researchers found that an increased intake of sodium at risk of getting a stroke significantly with 24% [95% CI = 1.08-1.43] increased.

The researchers found that an increased intake of sodium the risk of dying from stroke significantly with 63% [95% CI = 1.27-2.10] increased.

The researchers found that an increased intake of sodium the risk of dying from heart disease significantly with 32% [95% CI = 1.13-1.53] increased.

In children led a reduced sodium intake to a significant lowering of systolic blood pressure with 0.84 mmHg [95% CI = 0.25-1.43] and vacuum with 0.87 mmHg [95% = 0.14-1.60].

The subgroup analysis (to get additional information) showed that a reduced sodium intake the blood pressure in both people with high blood pressure as people with normal blood pressure reduced.

The researchers concluded that a low intake of sodium (equivalent to 5 grams of salt or less per day) blood pressure and chances of getting heart disease reduced.

1 grams of salt (sodium chloride) delivers 0.4 and 0.6 grams grams of sodium chloride. So 2 grams sodium corresponds to 5 grams of salt.
It's not salt but that sodium raises blood pressure. Starting from 2014, it is no longer required by the sodium content (though the salinity) of a food to mention on the packaging.

Low salt products are products with 0.1-0.5 grams of sodium per 100 g. What products 0.1-0.5 grams of sodium per 100 grams, you can look up here.
Salt-rich products are products with more than 0.3 grams of salt per 100 kcal or more than 0.5 grams of sodium per 100 g. With this formula, you can calculate, or a product in the supermarket salt is rich or not.
5 grams of salt per day corresponds to a power supply with up to 0.25 grams of salt per 100 kcal.

The researchers found a non-linear relationship between the magnesium intake via diet and reduced risk of getting heart disease. The reduced risk was highest between 150 and 400 mg of magnesium per day.

The researchers found that eating magnesium chances of getting heart disease in men with non-significant 13% [95% CI = 0.74-1.00] reduced and in women significantly with 14% [95% CI = 0.76-0.95] reduced. Non-significant is, there is no link to a 95% reliability.

The researchers found that each increase with 100 mg of magnesium per day the chance of getting heart disease significantly with 9% [95% CI = 0.86-0.96, there was a low heterogeneity between the studies] reduced. Not significant because the risk of 1 in the 95% CI of 0.86-0.96 sat.

The researchers found that the serum magnesium content of 2.07 mEq/L compared with 1.36 mEq/L, chances of getting heart disease significantly with 23% [95% CI = 0.66-0.87, there was a low heterogeneity between the studies] reduced.

The researchers found a linear relationship between the serum magnesium and the reduced risk of getting heart disease. The linear relationship was found between 1.44 and 1.8 mEq/l with a significant, lowered risk of 9% [95% CI = 0.85-0.97] per 0.1 mEq/l.

The researchers concluded that a non-linear relationship existed between the magnesium intake via food (150-400 mg per day) and the reduced risk of heart disease and a linear relationship existed between the serum magnesium (1.44-1.8 mEq/l) and the reduced risk of heart disease.

Research Question:
The association between the intake of magnesium through diet and the risk of getting colorectal cancer (colon cancer) is in many prospective studies examined, but it remains controversial because of inconsistent results. It was therefore carried out this review article.

Eating magnesium lowers the chances of getting colon cancer?

Study Design:
This overview article contained 7 prospective cohort studies until June 2012 with 333510 participants, of which 7435 patients with colon cancer.

Results and conclusions:
The researchers found that eating a lot of magnesium compared with little magnesium, the chances of getting colon cancer significantly with 19% [95% CI = 0.70-0.92] reduced. Significant is, there is a link at a 95% reliability.

The researchers found that eating a lot of magnesium compared with little magnesium, the chances of getting colon cancer in women significantly with 19% [95% CI = 0.68-0.94] reduced. Significant is, there is a link at a 95% reliability.

The researchers found that eating a lot of magnesium compared with little magnesium, the chances of getting colon cancer in men with non-significant 24% [95% CI = 0.51-1.01] reduced. Non-significant is, there is no link to a 95% reliability.

The researchers found a non-linear relationship between magnesium intake via diet and reduced risk of getting colon cancer. The reduced risk was the largest at 200-270 mg of magnesium per day.

The researchers concluded that eating 200-270 mg of magnesium per day the chances of getting colon cancer, especially in women reduced.

Colorectal cancer almost always arises from a polyp. A dikkedarmpoliep is an overgrowth of the lining of the colon. Most polyps are benign tumors and will continue too. Only in a small percentage polyps come "troubled cells" for. When malignant cells grow in the wall of the colon, we speak of colorectal cancer. 
Most of the tumors (50 to 60%) originates in the last parts of the colon: the sigmoid and rectum.

Colon cancer occurs mainly in people of 60 years of age and older. But colon cancer can also occur on (much) younger age. At 5 to 10% of patients with colon cancer there is heredity.

Colon cancer occurs slightly more often in men than in women.

Study Design:
This overview article contained 8 cross-sectional studies and 2 prospective cohort studies.

Results and conclusions:
The researchers found that 150 mg of magnesium per day through diet, the chances of getting it metabolic syndrome in adults significantly with 12% [RR = 0.88, 95% CI = 0.84-0.93, I2 = 36.3%] reduced.

The researchers found in the meta-regression analysis an inversely proportional relationship between the intake of magnesium (mg/day) through diet and getting the metabolic syndrome.

The researchers concluded that eating 150 mg of magnesium per day the chances of getting it reduced metabolic syndrome in adults. However, Rcts are needed to determine the causal connection between the magnesium intake and prevention of the metabolic syndrome.

Research Question:
Eating magnesium lowers the chances of getting cancer?

Study Design:
This overview article contained 6 case-control studies and cohort studies with 1236004 participants together 7.

Results and conclusions:
The researchers found that a high magnesium intake through diet, the chance of getting cancer significantly with 19.1% [RR = 0.801, 95% CI = 0.664-0.966] reduced.

The researchers found that a high magnesium intake through diet, the chance of getting cancer significantly with 33.7% [RR = 0.663, 95% CI = 0.475-.925] in case-control study reduced.

The researchers found that a high magnesium intake through diet, the chance of getting cancer non-significant with 11.2% [RR = 0.888, 95% CI: 0.745-1.060] in prospective cohort study reduced.

The researchers found that a high magnesium intake through diet, the chances of getting colon cancer significantly with 22.5% [RR = 0.775, 95% CI =-0.919 0.655] reduced.

The researchers found that a high magnesium intake through diet, the chance of getting cancer significantly reduced in women but not in men.

The researchers concluded that eating much magnesium the chance of getting cancer, especially colon cancer and especially among women reduced.
