during the menstrual cycle. is result is corroborated by other studies
evaluating women at childbearing age [2,17].
However, although there are still controversies related to changes
in energy consumption in the dierent phases of the menstrual cycle,
changes have been observed in the amount of ingested macronutrients
throughout the cycle such as concomitant increase in the consumption
of carbohydrates and lipids and reduction in proteins [1,4,17-19]. e
present study found results similar to those reported in literature such
as reduction in protein intake during the luteal phase. Some studies
indicate reduction in protein intake days before menstrual bleeding
[20] and in the bleeding period [21], as well as increase in the intake of
carbohydrates and lipids [4,17-24].
e literature shows that not only the quantity but the quality of
carbohydrates ingested has been evaluated. Changes in carbohydrate
quality during the menstrual cycle have been observed, with predominant
intake of simple carbohydrates from sweets and sugars in the luteal
phase [3]. is change in the intake of macronutrients, especially
those from sweets, has also been associated with mood improvement
during this period. It is believed that women increase carbohydrate
ingestion days prior to menstruation due to an unconscious search
for production of neurotransmitters related to mood improvement,
since carbohydrates, especially simple carbohydrates, increase the
tryptophan availability, precursor of serotonin in the brain [25].
Regarding the intake of minerals, all elements studied were ingested
in inadequate amounts throughout the cycle, indicating nutritional risk
in this population. In relation to sodium intake, all participants had
intakes above recommended values in both phases. In the study by
Santos et al. [3], in women in the luteal phase, increased consumption
of foods rich in sodium and fat was observed, which may be related to
the appearance of certain symptoms of the pre-menstrual syndrome
(PMS). One should also consider that high intake of this nutrient is
related to the development of coronary heart disease and high blood
pressure [26,27], hence the great importance of studies that can serve as
basis for the development of programs for the nutritional counseling of
women at childbearing age with or without symptoms of PMS.
Calcium intake during the study did not achieve adequate average
recommendations, presenting high frequency of low intake, which
result is in line with literature [28]. e intake of adequate amounts
of this mineral, especially in women during adulthood is essential to
prevent osteoporosis [28], since the calcium metabolism is inuenced
by female hormones [29]. Furthermore, inadequate intake of this
mineral has been associated with symptoms of PMS [30]. According
to clinical investigations conducted by ys-jacobs [31], low calcium
concentration can be involved in the etiology and emotional symptoms
of PMS [31].
Similarly, magnesium consumed in insucient amounts appears
to inuence the symptoms of PMS due to the reduction of its serum
concentration. In the body, this nutrient is involved in functions such
as regulation of serotonin and neurotransmitters. us, reduction
in the magnesium concentration may trigger emotional symptoms
related to PMS [32].
Studies have shown that changes that seem to occur in taste
during the menstrual cycle can inuence food intake among women
[5]. Among tastes studied, the acid taste was the only that had its
perception changed, with reduced sensitivity in the luteal phase. Kuga
et al. [5] suggested that changes in taste may occur in the luteal and
follicular phase, inuencing the choice of foods to be ingested. us, it
is suggested that the decreased sensitivity to acid taste possibly induces
the search for foods containing this taste. Usually, foods with this
feature are those at the top of the Food Guide Pyramid, which should
be consumed with caution and moderation.
Foods with acid taste are oen sugary or those with some degree of
sweetness, such as citrus fruits, so drinks and some candies. Studies
on dietary intake during the menstrual cycle have found changes in the
type of food selected during the cycle, with increased consumption of
sweets and sugars [3]. us, it is suggested that decreased perception
to acid taste in the luteal phase may reect a possible search for sweet
foods during this period.
In the present study, it was found that volunteers who had low
serum progesterone concentrations only perceived salty taste at
higher concentrations, while volunteers who had adequate serum
concentrations of this hormone perceived salty taste at lower
concentrations, which, in part, can justify the search of women for
salty foods in the luteal phase of the menstrual cycle. In the study by
Alberti-Fidanza et al. [6], where the sensitivity to tastes was analyzed,
the authors concluded that the sensitivity to salty taste is impaired due
to the progesterone concentration, and sweet and acid tastes can also be
inuenced by the hormones estrogen and progesterone, respectively.
According to these authors, sensitivity to sweet taste is increased
according to the estrogen levels and when progesterone concentration
rises, sensitivity to bitter taste increases. ese authors did not identify
inuences on sensitivity to acid taste.
Although no changes in the bitter taste perception have been
identied, positive associations were found between bitter taste
perception and the intake of calories, carbohydrates and lipids in
the luteal phase of the menstrual cycle. It seems that the bitter taste
induces food intake cession, when this occurs excessively. e bitter
taste perception by the tongue is involved in inducing the nishing
of the food intake. e identication of this taste causes an aversive
response, so as to avoid the intake of food toxins, which usually have
characteristic bitter taste [33-36]. Recent studies have evidenced the
presence of bitter taste receptors elsewhere in the digestive system
besides the oral cavity, such as in the intestine. ese receptors have also
been related to increased secretion of intestinal peptides responsible
for reduced appetite such as cholecystokinin (CCK) and glucagon-like
peptide-1 (GLP-1) [37].
It seems that in conjunction with the mechanism involved in food
intake cession involving the bitter taste also involves hormone insulin.
e anorectic eects of this hormone are well elucidated in literature
[38]. According to the results found in this study, during the luteal
phase, there is a trend of positive association between hormone insulin
and the bitter taste perception. It is assumed that this hormone when
in high concentrations leads to an increase in bitter taste perception,
also increasing GLP-1, thereby increasing serum insulin levels and also
delayed gastric emptying and induction of food intake cession.
Shin et al. [39] demonstrated the ability of ghrelin in modifying the
gustative quality. According to these authors, ghrelin may be produced
by taste receptors, with an eect on the perception of sweet, acid and
umami tastes. In the present study, trend towards a negative association
between hormone ghrelin and acid taste was identied, hypothesizing
that high concentrations of this hormone lead to reduced acid taste
perception.
In relation to female sex hormones and appetite regulators, no
associations were found. ese results corroborate those found by
Dafopoulos et al. [40].
