What foods are bad for aging skin?
Eating fruit and
vegetables, apart from the many well-known nutritional benefits it brings,
would also have a clear anti-aging function.
Eating fruit has
multiple health benefits. Just thinking about the great variety that both
fruits and vegetables contain, many of them forgotten within the
ultra-processed foods that make up the terrible Western Diet, is enough to
realize the great nutritional treasure that these foods hide. In fact, many of
these ultra-processed ones use advertising messages where they pride themselves
on containing X or Y nutrients, trying to imitate fruits and vegetables.
One of the many
substances that are often mentioned as beneficial when eating fruit or
vegetables are usually " flavonoids ", which also accompany the
nutritional statements of other foods, such as dark chocolate or even wine;
although in the latter case we know that the harms (alcohol) outweigh the benefits.
Now, new research,
recently published in the journal EBioMedicine, has concluded that a particular
flavonoid found in various fruits and vegetables has a potential new effect: It
can keep us younger.
The
anti-aging effects of eating fruit
The fisetin, a
flavonoid that can be found in many fruits and vegetables, would that natural
flavonoid, whose senolĂtico effect would grant such potential. In other words,
this flavonoid would be able to eliminate cells damaged in the body due to
aging, thus being able to improve general health and extend useful life.
We must bear in mind
that aging is something natural that cannot be eliminated in human life, but it
takes nothing more than to go outside to realize that some individuals cope
better than others: human aging does not understand age, but feeding. That is,
although it is true that (logically), "the older, the more aging", it
is possible to delay this natural process, either through good genetics, or
through a good diet.
Every so often, human
cells, from any part of the body, end up losing their ability to divide
effectively and the immune system "cleanses" the trail when they die.
But, as we age, the immune system also becomes less efficient and erratic in
its task. Thus, damaged cells, or senescent cells, can accumulate and lead to
chronic diseases related to age, and some of them can start even at an early
age if a healthy lifestyle is not carried out. It is what is commonly called
“aging badly”.
Although multiple
investigations are currently being carried out with the aim of artificially
eliminating the accumulation of these aging and harmful cells, the so-called
senolytic drugs, such as those discussed in a study published in Nature in
early 2018, the reality is that improving Its lifestyle in general would be
crucial to avoid the accumulation of these cells.
Flavonoids,
the anti-aging effect of eating fruit
All these senolytic
drugs are based on the use of flavonoid compounds, and that is why it has been
discovered that fisetin would be a potentially effective compound to prevent
aging, both in mice and in humans. However, ideally, eating fruit and
vegetables would be an alternative way to avoid such aging rather than resorting
to medication.
In fact, fisetin was
already known before, although its anti-aging potential had not been so
directly exploited. As early as 2014, in a study published in Aging Cell, a
fisetin-based compound was able to prevent the progression of Alzheimer's
disease, although at that time only hypotheses could be made about fisetin and
its potential, without being able to clearly link it to an anti-aging effect as
such.
In this new research,
thanks to a technology called mass cytometry, it has been possible to observe
how the compound, a fisetin- based compound, would act within a senescent cell
in a specific way, in mice. In addition, its effects on general health could
also be verified, reducing biomarkers of age-related diseases and extending the
average life expectancy of rodents.
Eating
fruit: easier and more natural
At the moment almost
all the research regarding flavonoids in general and fisetin in particular has
been done in mice, and this particular work is still in its early stages.
Still, since eating fruits and vegetables can provide fisetin and other flavonoids,
these compounds being natural and easily accessible, the effects in humans are
expected to be similar or even better.
Researchers hope to
quickly reach clinical trials in humans, although the reality of the ordinary
individual is easier and different, it is another level: the reality is that
there is a lot of talk about developing this or that drug, but always
emphasizing that They are based on natural compounds found in the supermarket. Therefore,
the easy conclusion would be that eating fruit and vegetables, in quantity, as
has always been recommended, and without the need to process them or extract
their molecules in an artificial and isolated way, would be enough to improve
our aging and even delay it.
If your blood
pressure is elevated and you want to see an immediate
change, lie down and take deep breaths. This is how you lower your blood
pressure within minutes, helping to slow your heart rate and decrease your
blood pressure. When you feel stress, hormones are released that constrict your
blood vessels.
