Calcium alginate and blood fats after a fatty meal
What it found
In healthy adults, taking calcium alginate with a fatty meal led to lower blood triglyceride and remnant-like lipoprotein cholesterol levels than a placebo.
The trial was small and short.
What they found
Studies in people
Triglycerides lower
Triglyceride levels were significantly lower at all time points in the calcium alginate group compared to the control group, starting 2 hours after the fatty meal.
Remnant cholesterol lower
Remnant-like lipoprotein cholesterol levels were also significantly lower at all time points in the calcium alginate group compared to the control group.
Overall exposure lower
The total exposure to triglycerides over 6 hours and the highest level reached were both significantly lower in the calcium alginate group than in the control group.
Calcium and sodium changes
At 6 hours after the fatty meal, the change in serum calcium was significantly increased, while the change in serum sodium was significantly decreased in the calcium alginate group compared to the control group.
What the authors conclude
“These results indicate that Ca-Alg may have broad applications as a supplement that also contributes to the prevention of lifestyle-related diseases such as hyperlipidemia.”
Also in their conclusions
- They say that calcium alginate may have broad applications as a supplement that also contributes to the prevention of lifestyle-related diseases such as hyperlipidemia.
How it was done
The authors wanted to see whether calcium alginate could help prevent lifestyle-related diseases such as hyperlipidemia.
Eight healthy adults ate a fat-loaded food and then took either a placebo or 1.5 g of calcium alginate (300 mg per capsule, 5 capsules). Blood levels of triglycerides and remnant-like lipoprotein cholesterol were measured before and at 2, 3, 4 and 6 hours after the meal.
What it can’t tell you
- We summarised it from the abstract only.
- The trial was very small and only looked at one dose over a few hours. It cannot show what happens with long-term use or in larger groups of people.
