Omega-3 From Seafood Is Kidney-friendly

Omega-3 From Seafood Is Kidney-friendly

Fish is a nutritious food. It is an excellent protein source and filled with omega-3 fatty acids. Fatty cold-water fish like salmon, sardines, mackerel, and herrings, as well as, to a lesser extent, shellfish like oysters, mussels, and crab, are some of the richest dietary sources of these fatty acids. Research led by the George Institute for Global Health and the University of New South Wales has suggested that eating at least 2 portions of oily fish is associated with a lower risk of chronic kidney problems.


The research team combined the findings of 19 studies from 12 nations examining the connection between omega-3 fatty acid levels and the onset of chronic kidney problems in adults. The main analysis comprised about 25000 individuals, ranging in age from 49 to 77.


Participants were split into groups based on how much seafood omega-3 fatty acids they consumed, and those in the highest fifth had a 13% lower risk of developing chronic kidney problems than those in the lowest fifth. A Higher level of seafood omega-3 fatty acids was linked to an 8% decreased chance of getting chronic kidney problems after variables such as age, sex, race, body mass index, smoking, alcohol use, physical activities, and other chronic health issues were taken into account. A slower annual loss in renal function was linked to higher levels. However, this link was not found with higher plant-derived omega-3 fatty acids consumption.


While the findings were observational and did not prove that including more seafood in the diet would surely lower the risks of chronic kidney problems, the results appeared consistent across age groups.

"Can doctors know how well my kidney is functioning by simply looking at my creatinine level in blood?" That's properly a common question to ask. In short, the answer is no. Today, we will go through what creatinine is and how it is linked with kidney function.   Creatinine is a waste product produced when creatine, a molecule that provides energy to the muscles, is broken down. Creatinine is then eliminated from the body through the kidneys. When the ki
Swelling is one of the common signs for people living with kidney problems. It often indicates the kidneys do not remove excess fluid. Swelling can happen in ankles, feet, or any body part. It is rather uncomfortable because it can affect walking or cause shortness of breath.   There is an easy test to get an idea if one has swelled. Press on a bony area on the lower legs for around 5 seconds. Observe any pit formed, and if there is a dimple, note the depth of the pit
Hit Questions
How long does it take to see results? Should I stop taking it after a while? Are there any side effects? These are some of the most common questions we get, and let’s find out the answer together.   How long does it take to see results? Results often vary among different users, as no two individuals have the same condition, diet, and lifestyles, which could all play parts in the effects of DTS. Kidney damage is known to be irreversible
DTS is scientifically proven to be beneficial to kidney function and has a positive effect on supporting the eGFR level. It is suitable for people to use as kidney support. Some may wonder, how about individuals without any kidney issues? Is DTS good for them too?   Absolutely yes! As “prevention is better than cure” is one of the basic modern healthcare strategies, the best time to take DTS is right before any kidney and liver problems show up. The herbal
Using creatinine as an indication of kidney function level is common, but just this number alone is not the optimal way to monitor kidney health nor to detect early kidney problems. According to professional recommendations, using an eGFR level is a more accurate indication of kidney health.   Creatinine is a by-product generated from protein metabolism. Therefore, muscle mass and diet can affect creatinine generation. For example, a muscular person or a person who cr
A study conducted in 2016 has shown that extracts from different parts of Eucommia, such as bark, stem, and seeds, contain health-promoting properties. Here are some examples:   1. Eucommia bark extract demonstrates an antihypertensive effect, confirmed by many human and animal models. 2. Under vivo and vitro studies, Eucommia has established strong antioxidant properties. 3. Eucommia leaf extract shows properties that promote the
