The Ganepão conference considers, within its educational proposal, the dissemination of knowledge as a fundamental action. On this space, you can follow relevant nutrition contents based on scientific evidence.
A new study that followed more than 2,600 men and women for 16 years found that consuming less sodium wasn't associated with lower blood pressure. The new findings call into question the sodium limits recommended by the current Dietary Guidelines for Americans.
The 2015-2020 Dietary Guidelines for Americans recommends limiting sodium intake to 2300 milligrams a day for healthy people. For the study, the researchers followed 2632 men and women ages 30 to 64 years old who were part of the Framingham Offspring Study. The participants had normal blood pressure at the study's start. However, over the next 16 years, the researchers found that the study participants who consumed less than 2500 milligrams of sodium a day had higher blood pressure than participants who consumed higher amounts of sodium.
The researchers also found that people in the study who had higher intakes of potassium, calcium and magnesium exhibited lower blood pressure over the long term. In Framingham, people with higher combined intakes of sodium (3717 milligrams per day on average) and potassium (3211 milligrams per day on average on average) had the lowest blood pressure.
"This study and others point to the importance of higher potassium intakes, in particular, on blood pressure and probably cardiovascular outcomes as well," said the author. "I hope that this research will help refocus the current Dietary Guidelines for Americans on the importance of increasing intakes of foods rich in potassium, calcium and magnesium for the purpose of maintaining a healthy blood pressure."
The author says that there is likely a subset of people sensitive to salt who would benefit from lowering sodium intake, but more research is needed to develop easier methods to screen for salt sensitivity and to determine appropriate guidelines for intakes of sodium and potassium in this salt-sensitive group of people.

Even with the long holiday and cold temperature in São Paulo City, our conference reached the considerable mark of 2,579 participants.
Ganepão 2017 contemplated the 7th Brazilian Congress of Integrated Nutrition - CBNI, with the theme "Translating Nutrients and Nutraceuticals in Nutrition Prevention and Therapy", and the 3rd Brazilian Congress of Pre, Pro and Symbiotics - Preprosim, under the theme "Organic and al Repercussions Of Dysbiosis: Diagnosis and Treatment".
The Conference had 5 days of intense scientific activity, where 5 Pre-Congress Courses were held, 755 lectures distributed in 10 rooms, 8 of them with simultaneous translation. In addition, we had a simultaneous real-time broadcast room.
The active participation of 306 teachers, 21 of them internationally renowned, guaranteed excellent scientific programming with a multidisciplinary proposal to update participants.
The presence of Brazilian research was reflected in 268 scientific papers presented, with 6 of them being awarded in the 3rd Preprosim / FQM Award and another 8 papers in the 19th Paulista Research Forum of Clinical and Experimental Nutrition. The contributions were made available in annals, as an electronic supplement in BRASPEN's Brazilian Journal of Clinical Nutrition. Download by clicking HERE (portuguese only).
Ganepão 2017 was realized with the support of important Entities, Councils and Associations of the areas of Medicine, Nutrition, Nursing and Pharmacy, national and international.
Our partners in the Food Industry and Laboratories unanimously evaluated the scientific programming and general organization of Ganepão 2017 as "optimum".
