To provide an overview of recent research that collectively demonstrates the potential for peanuts as an aid to weight management.

Research on nuts and their effects on health has been plentiful in recent years. This short literature review focuses principally on that research relevant to peanuts.

Epidemiological and intervention studies have provided useful information on the beneficial effects of nuts, including peanuts in relation to weight management and obesity. This has served to overturn the perception that peanuts, due to their fat content, should not be included in weight loss diets. Furthermore, that, for effective weight management, a moderate fat diet, that includes peanuts, may be more effective for both cardiovascular health and weight management.

More definitive research to directly assess the effects of peanuts on energy balance and body weight is recommended to ascertain optimal quantities of peanuts that can be included in diets for both weight loss and weight maintenance. Plausible explanations for the absence of expected weight gain with regular nut consumption are reported and further research to explore these theories will be reassuring.

Inclusion of daily 1oz(30g) handfuls of peanuts within a moderate fat diet can be recommended as a useful means not only to improve diet quality but also to assist with weight management, due to their satiating effects.

This paper will be useful to health professionals and educators by highlighting how a convenient snack food, peanuts can play a beneficial role within a healthy diet for both cardiovascular protection and weight management.

The peanut is not in fact a nut at all. It is the seed of an annual legume, akin to beans, peas and lentils. The plants grow close to the ground and bear pods containing the peanuts below the surface. This is why they are still sometimes referred to as ‘groundnuts’.

This paper reviews the nutritional profile of peanuts and summarises recent evidence for their potential as a beneficial food for long‐term health. As such, a more constructive positioning for peanuts and peanut butter within the UK diet is proposed.

This paper summarises recent evidence and consider a more constructive positioning for peanuts and peanut butter within the UK diet. It also briefly discusses the protective role that peanuts may have against certain diseases. The beneficial effects of peanuts in the prevention of coronary heart disease are discussed in detail.

The purpose of this paper is to determine the effect of the genotype on the mineral composition (Ca, Cu, Fe, Mg, Mn, Se, Zn and K) of peanuts.

Samples of peanut of three genotypes common names cultivar cavalo vermelho (CCV), cultivar cavalo rosa (CCR) and cultivar tatu (CTA) were used. They were grown in the Maringá, Paraná State region in the same period and were purchased directly from the producer. About 500 g of each genotype were purchased and divided into five equal parts. Each part was analyzed separately and in triplicate (n=15). Mineral analysis was performed in an atomic absorption spectrophotometer with flame ionization.

Among the analyzed minerals, K occurred in the greatest amount (−600 mg · 100 g⁻¹ of sample), followed by Mg (−250 mg · 100 g⁻¹ of sample), and calcium (−65 mg · 100 g⁻¹ of sample). These values were statistically equal for the investigated genotypes. The iron content varied significantly between samples (from 2.7 to 4.6 mg · 100 g⁻¹ of sample). Zinc content ranged between 6 and 10 mg · 100 g⁻¹ of sample. The contents of the other minerals (Cu, Mn, and Se) were lower than 4 mg · 100 g⁻¹ of sample for all genotypes. The quantities of Mn and Se ranged between 1.2 and 2.1 mg · 100 g⁻¹.

Have few studies of comparative variation in minerals contents in different genotypes of peanuts. In relation to the RDI, the paper observed that 100 g of peanuts can provide significant amounts of most minerals or even more than the RDI amounts, all genotypes being very nutritious.
