Eating peanuts, chickpeas may lower cholesterol, improve BP
Washington, June 5: Eating a diet that includes peanuts, chickpeas, apples and a little amount of plant sterols may lower cholesterol and improve blood pressure, new research has found.
The diet is based on the "Portfolio Diet," which is a plant-based dietary pattern that emphasises a portfolio of four proven cholesterol-lowering foods.
"Previous clinical trials and observational studies have found strong evidence that a plant-based diet can improve heart health," said one of the study authors, Hana Kahleova, Director of Clinical Research at the Physicians Committee for Responsible Medicine in Washington DC.
"This study demonstrates that certain plant foods are especially effective for lowering cholesterol and boosting our overall cardiovascular health," Kahleova added.
The diet that the researchers found beneficial included 42 grams of nuts (tree nuts or peanuts), 50 grams of plant protein from soy products or dietary pulses (beans, peas, chickpeas, or lentils), 20 grams of viscous soluble fiber from oats, barley, psyllium, eggplant, okra, apples, oranges, or berries and two grams of plant sterols from supplements or plant-sterol enriched products per day.
The findings, published in the journal Progress in Cardiovascular Diseases, are based on a new meta-analysis, a statistical procedure that integrates the results of several independent studies.
The results suggest that a diet that includes plant protein, fiber, nuts and plant sterols improves several markers for cardiovascular disease risk including reductions in cholesterol level and improvements in blood pressure.
Following the dietary pattern reduced LDL (low-density lipoprotein), the "bad" cholesterol by 17 per cent, while also reducing total cholesterol, triglycerides, systolic blood pressure, diastolic blood pressure and C-reactive protein.
It also helped reduce 10-year coronary heart disease risk by 13 per cent, the study said.

ISRO successfully conducts hot tests of Gaganyaan propulsion system
Bengaluru (PTI): ISRO has successfully conducted two hot tests of the Gaganyaan Service Module Propulsion System (SMPS) at the space agency's Propulsion Complex in Mahendragiri on July 3.
The short-duration tests, lasting 30 seconds and 100 seconds respectively, were aimed at validating the test article configuration, ISRO said in a statement on Wednesday.
"The overall performance of the propulsion system during these hot tests was normal as per pre-test predictions. During the 100s test, simultaneous operation of all Reaction Control System (RCS) thrusters in different modes (steady state; pulsed) along with all Liquid Apogee Motor (LAM) engines was also successfully demonstrated.
"ISRO's Liquid Propulsion System Centre (LPSC) is leading the technology development activities for the Gaganyaan SMPS. SMPS is a critical system of Gaganyaan Orbital Module and is required during orbital manoeuvring as well as specific abort scenarios," the space agency said.
It comprises five Liquid Apogee Motor (LAM) engines (each 440N thrust) and 16 Reaction Control System (RCS) thrusters (each 100N thrust). In order to simulate the propulsion system conditions closer to flight, the SMPS test article for these hot tests incorporated improvements based on experience gained from earlier hot tests.
"With the confidence gained through these hot tests, ISRO will conduct a full duration hot test shortly," the statement said.
According to ISRO, the Gaganyaan programme aims to demonstrate India’s capability to launch a crewed spacecraft into low Earth orbit, and the experience and knowledge gained from this mission will be crucial for its success.
