Yes, thirty days of McDonald’s meals causes weight gain, even heart palpitations. But what happens to your arteries?
For the first time, a short term, six week, study (using mice) shows that a similar diet causes arteries to begin clogging, and worse, affects its structural and mechanical properties. This study used a high fat diet comprised of about 36% of calories as fat; a Big Mac has about 49%.
From the study:
The arterial compliance was compared between control and high fat-fed mice for 6 weeks.We show that the compliance of the TDAs was dramatically reduced in high fat-fed mice whereas the compliance of the carotids remained unchanged. An abundance of collagen deposition in the media/adventitia of the carotids and TDAs was observed in high fat-fed mice. These results demonstrate that the structural and mechanical properties of small arteries are rapidly altered even after only 6 weeks of high fat feeding.
Take a look for yourself. Tha’ts food for thought the next time you visit a fast food restaurant!
