The comparison method, a dietary approach to stopping hypertension or DASH (Dietary Approaches to Stop Hypertension) diet emphasise fruit, vegetables and whole grains, reduced meat and dairy intake and eliminating snack food. "We can now say the dietary portfolio is ideal for reducing overall risk of cardiovascular disease," he added.Īlso read: Want to get slim? Eat fruits, cereal and dairy for breakfast Michael's Hospital and professor at the University of Toronto. "This is an important secondary finding to the original study, adding to the literature connecting diet with health," said Dr David Jenkins, study's lead author from St. The portfolio diet includes foods that are scientifically-proven to lower cholesterol including mixed nuts, soy protein, plant sterols (found in vegetable oils and leafy vegetables) and viscous fibre (found in oats, barley and eggplant). Some patients also choose the portfolio diet for ethical and environmental reasons – plant-based diets generally have a smaller eco-footprint than standard Western diets – or in the case of children, to head-off future health problems.The new research was a secondary analysis of data collected for a 2011 study on the effect of the "portfolio diet" on cholesterol. “Especially with chronic lymphocytic leukemia, prostate cancer, and other watch-and-wait diseases, reducing inflammation may greatly extend a patient's lifetime,” says Jenkins. Growing evidence suggests inflammation plays a role in cardiovascular disease, but recent studies have linked it to a host of other diseases, including cancer.

Indeed they’ve shown that by following this approach you can bring about a 25 reduction in your cholesterol levels.

The study's findings on inflammation are particularly exciting, Jenkins says. The Portfolio Diet is a recognised dietary approach to lowering cholesterol - what is interesting about this ‘diet’ is that it’s all about combining groups of food which have been shown in studies to lower bad cholesterol. It's not an all or nothing proposition, which is why we also call it a dietary portfolio,” says Sievenpiper. “One nice thing about the diet is that the effects are additive, so adopting one or more components is better than none. “The same is not true for drugs, and they often produce other effects you don't want.”Īdherence to the diet can be challenging for some patients, but many find that incorporating just a few more plant-based foods offers noticeable benefits.

“We're starting to say to patients, ‘This diet will help you meet your cholesterol goals, but it will also improve your blood lipids and blood pressure, and lower inflammation,’” says Sievenpiper. “But when you pool the results of several trials, the risk reductions become clear and together they provide a really strong case for the cardiovascular benefits of the dietary portfolio.”ĭietary and lifestyle modifications can enable patients to manage high cholesterol and cardiovascular risk, and the current study provides further rationale for that approach. “When you look at individual trials alone, data on these other risk factors can appear random,” says David Jenkins, a professor in the Departments of Nutritional Sciences and Medicine at U of T who holds a Canada Research Chair in Nutrition and Metabolism, and who developed the portfolio diet in the early 2000s. The researchers conducted a meta-analysis that combined results from seven controlled trials involving more than 400 patients, and found that specific risk factors varied from about a 2 percent reduction (for blood pressure) to a 32 percent reduction (for inflammation). “This study allows for greater clarity and certainty about the effects of the diet and its health potential.”

“We've known the portfolio diet lowers LDL cholesterol, but we didn't have a clear picture of what else it could do,” says John Sievenpiper, Associate Professor in the Department of Nutritional Sciences at U of T and a staff physician and scientist at St. and 2 grams of plant sterols – natural compounds that inhibit absorption of cholesterol and are often included in enriched products like margarine. Based on a 2,000 calorie diet, it includes 45 grams of nuts, or about a handful 50 grams of plant protein such as soy, or pulses like beans and peas 20 grams of viscous soluble fiber from oats, eggplant, apples, etc. The portfolio diet has four main components. In addition to reducing LDL (or “bad”) cholesterol by about 30 percent when combined with a low-saturated fat diet – a level comparable to medications – the researchers found the diet limited other factors for an estimated 13 percent reduction in the overall risk for coronary heart disease, which includes angina and heart attack. The portfolio diet, a plant-based way of eating previously shown to lower cholesterol levels, also reduces other risk factors for cardiovascular disease including blood pressure, triglycerides and inflammation, University of Toronto researchers have found.
