Conclusions Plant-based diets are associated with decreased total cholesterol , low-density lipoprotein cholesterol , and high-density lipoprotein cholesterol , but not with decreased triglycerides .
Context Although a recent meta- analysis of r and omized controlled trials showed that adoption of a vegetarian diet reduces plasma lipids , the association between vegetarian diets and long-term effects on plasma lipids has not been subjected to meta- analysis .
Objective The aim was to conduct a systematic review and meta- analysis of observational studies and clinical trials that have examined associations between plant-based diets and plasma lipids .
Nutrition intervention for migraine: a randomized crossover trial
Background Limited evidence suggests that dietary interventions may offer a promising approach for migraine . The purpose of this study was to determine the effects of a low-fat plant-based diet intervention on migraine severity and frequency . Methods Forty-two adult migraine sufferers were recruited from the general community in Washington , DC , and divided r and omly into two groups . This 36-week crossover study included two treatments : dietary instruction and placebo supplement . Each treatment period was 16 weeks , with a 4-week washout between . During the diet period , a low-fat vegan diet was prescribed for 4 weeks , after which an elimination diet was used . Participants were assessed at the beginning , midpoint , and end of each period . Significance was determined using student ’s t-tests . Results Worst headache pain in last 2 weeks , as measured by visual analog scale , was initially 6.4/10 cm ( SD 2.1 cm ) , and declined 2.1 cm during the diet period and 0.7 cm during the supplement period ( p=0.03 ) . Average headache intensity ( 0–10 scale ) was initially 4.2 ( SD 1.4 ) per week , and this declined by 1.0 during the diet period and by 0.5 during the supplement period ( p=0.20 ) . Average headache frequency was initially 2.3 ( SD 1.8 ) per week , and this declined by 0.3 during the diet period and by 0.4 during the supplement period ( p=0.61 ) . The Patient ’s Global Impression of Change showed greater improvement in pain during the diet period ( p<0.001 ) . Conclusions These results suggest that a nutritional approach may be a useful part of migraine treatment , but that method ologic issues necessitate further research .Trial registration Clinical trials.gov , NCT01699009 and NCT01547494
