The high monounsaturated fat peanut diets lowered their total body
cholesterol by 11 % and bad LDL cholesterol by 14 %, while their good
HDL cholesterol was maintained with reduction in triglycerides (Pelkman ).
The benefits of the peanut diets on cholesterol were comparable to the olive
oil diet. There is strong evidence supporting an association between
monounsaturated fat as well as overall nut intake and reduction in the risk of
coronary heart disease (Matilsky et al. ). https://www.ozstarmakina.com/en
Emerging data clearly shows that type of fat can impact health in
various ways at different stages of life. The fat in peanuts and peanut butter
provides healthy calories to malnourished infants and children at their time of
need. https://www.ozstarmakina.com/en
Peanuts are actually a legume and have more protein
than any other nut with levels comparable to or better than serving of beans.
After the peanut oil is extracted, the protein content in the cake can reach
50 %. Peanuts contain all the 20 amino acids in variable proportions and
is the biggest source of the protein called “arginine”. https://www.ozstarmakina.com/en According
to Protein Digestibility Corrected Amino Acid Score (PDCAAS) peanut proteins
and other legume proteins such as soy proteins are nutritionally equivalent to
meat and eggs for human growth and health.
The amino acid profile of the peanut
meals shows that it can be an ingredient for protein fortification. Since the
proteins in peanuts is plant based, it carries with it additional components
that have positive health benefits like fiber and unique bioactive components,
unlike animal protein. https://www.ozstarmakina.com/en
The peanut proteins have been found to have good emulsifying activity,
emulsifying stability, foaming capacity, excellent water retention and high
solubility, and can also provide a new high protein food ingredient product
formulation and protein formulation in food industry. Based on these
observations, recently peanut protein has been incorporated into noodles and
infant formula. There is a renewed interest in the studies related to the
flavors in the peanut kernel and skin.
The components in peanuts are highly
digestible. https://www.ozstarmakina.com/en
The true protein digestibility of peanuts is comparable with that of animal
protein. The limiting amino acid in peanuts varies based on the study i.e.
lysine, methionine or threonine. Protein quality is defined based on the amino
acid pattern and percent of digestibility of proteins. https://www.ozstarmakina.com/en
The
PDCAAS for peanuts has been estimated to be about 0.70 out of 1 where as for
whole wheat PDCASS is 0.46. Fat digestibility varies based on the structure of
different fatty acids. Peanuts contain over 50 % monounsaturated fats,
which are easily digested due to single unsaturated hydrogen bond which is
easily broken. Since peanuts are legumes, they contain phytic acid which is
associated with decreasing the bioavailability of other nutrients due to their
binding properties, but the amount in peanuts is lower than compared to other
legumes such as soybean. https://www.ozstarmakina.com/en
The fiber in peanuts is mainly
insoluble, with lower amounts of soluble fiber. It contributes to daily intake,
but has not been shown to bind nutrients and restrict their absorption. In
fact, the small amount of soluble fermentable fiber may improve adsorption of
some minerals. Peanuts are also a good source of fiber, according to the Food
and Drug Administration. Sucrose and starch constitute the major while reducing
sugars form the minor proportion of the peanut carbohydrates. https://www.ozstarmakina.com/en
This
may contribute to the fact that peanut have a low glycemic index (GI) and
glycemic load (GL) . On a 100 –point scale, the GI of peanuts is 14, and the GL
of peanuts is one. https://www.ozstarmakina.com/en
Additional research has shown that when
peanuts or peanut butter are added to a high glycemic load meal, such as with a
bagel and a glass of juice, they actually keep the blood sugar stabilized so
that it does not rise too high too quickly (Johnston et al.
