Summary
Flaxseed, a humble and inexpensive superfood, shows significant potential in managing blood pressure, body mass index, and cholesterol levels, according to a recent study published in the journal Explore. The research, conducted in Iran, involved hypertensive patients who were given either 10 or 30 grams of flaxseed daily or a placebo over a 12-week period. The results indicated that those consuming 30 grams of flaxseed experienced a notable reduction in systolic blood pressure, dropping from an average of 148.38 mmHg to 135 mmHg, while the placebo group saw a slight increase.
The study's design included a placebo that mimicked the taste and appearance of flaxseed, ensuring that participants were unaware of their group assignments. This rigorous methodology helped rule out placebo effects, lending credibility to the findings. Additionally, the 30-gram group showed improvements in diastolic blood pressure and body mass index, while the 10-gram group also reported reductions, albeit to a lesser extent.
Flaxseed is rich in omega-3 fatty acids, fiber, and antioxidants, which may contribute to its health benefits. The researchers speculate that compounds in flaxseed, particularly lignans, could work similarly to certain blood pressure medications without the associated side effects. This study highlights the importance of natural dietary interventions in managing health conditions, suggesting that incorporating flaxseed into daily diets could offer a simple yet effective strategy for improving cardiovascular health.

Expired contains multiple eye-opening revelations about covid with compelling evidence that provides a coherent, sober and clear explanation that better fits the data we have so far. Meticulous research by pathologist Dr Clare Craig sheds light on the largely overlooked evidence of airborne virus transmission, examining twelve related beliefs on spread, lockdowns, asymptomatic infections, and masks. In addition, Expired champions the importance of Western ethical principles, damaged by pandemic actions and calls for their restoration. The covid debate has proved incredibly polarising. One side believed every intervention was saving lives, while the other emphasised the harms caused. Biased modelling based on a worst-case scenario led to fearful assumptions presented as fact. By dint of sheer repetition these ‘facts’ became unquestionable. Those scientists who dared to question were proclaimed dangerous. Welcome to Cloud-Covid-Land.Let’s bring back nuance. It’s time to return to reality." Learn more about your ad choices. Visit megaphone.fm/adchoices Learn more about your ad choices. Visit megaphone.fm/adchoices
