Leguminous seeds in the dietary management of hyperlipemia

Abstract

Seven male hyperlipidemic patients substituted approximately 140g dried beans daily for other sources of starch in their diet over a 4-month period. After this, mean fasting serum triglyceride levels were reduced by 25 +/- 5% (p less than 0.01) while total serum cholesterol levels were 7 +/- 2% (p less than 0.5) lower than the values measured during the previous five clinic attendances (12 +/- 2.5 months). However, low- and high-density lipoprotein cholesterol levels remained unaltered. While taking beans a nonsignificant fall (0.7 kg) was seen in body weight. Nevertheless no change was seen in macronutrient intake determined by 1-wk diet histories recorded both before and four times during the study, although cholesterol intake decreased by 80 mg (p less than 0.02). Reintroduction of dried leguminous seeds into a Western diet may be a useful adjunct to the management of hyperlipidemia.

The Influence of Legume Seeds on Human Plasma Lipid Concentrations

“…However, Jenkins et al (1983) did not find a consistent relationship between the initial lipid levels of their seven subjects (three type I1 and four type IV) and the reduction in cholesterol seen as a result of a legume-rich diet. In fact, in this study, the greatest reduction was seen in a type IV subject with a relatively low starting cholesterol level.…”

Lupin kernel fibre-enriched foods beneficially modify serum lipids in men

“…Jenkins and coworkers recently proposed the 'Portfolio diet' as a new approach to lipid management: the diet utilizes a combination of hypocholesterolaemic agents such as psyllium, oats, nuts, plant sterols and soy protein to provide an additive effect in reducing total and low-density lipoprotein cholesterol (LDL-C), equivalent to first-line drug therapy (Jenkins et al, 2002a(Jenkins et al, , 2003. Dietary intervention studies have shown that numerous legumes (eg, soy beans, navy beans, field beans, lentils, chickpeas and pinto beans) beneficially modify serum lipids (Jenkins et al, 1983;Anderson et al, 1984Anderson et al, , 1990Anderson et al, , 1995Duane, 1997;Fruhbeck et al, 1997). In a recent meta-analysis of non-soy legumes, beneficial effects on serum lipids were partly attributed to the dietary fibre component of these legumes (Anderson & Major, 2002), which was primarily soluble in nature.…”

Extruded dry beans and serum lipoprotein and plasma haemostatic factors in hyperlipidaemic men

“…Some studies reported lowering effects (Anderson et al, 1990;Shutler et al, 1989), others increasing effects (Mackay & Ball, 1992) while some reported no effects (Anderson et al, 1984;Cobiac et al, 1990;Jenkins et al, 1983). The decrease in serum HDL-C concentrations in this study was probably not an independent effect of extruded dry beans because a lowering effect was also seen in the control group.…”

“…The extruded dry bean products were supplied to the subjects. The subjects had to exchange carbohydrate foods for the extruded dry bean products (as in the studies of Jenkins et al (1983) and Mackay & Ball (1992 Preceding the study all the subjects and their wives were invited to an information session where all aspects of the study were discussed and the necessary instructions and directions given. To ensure compliance to the experimental intervention, the subjects could taste some of the extruded dry bean products during this session.…”
