Scientists are working to make "junk food" healthier

Pizza
is widely considered an important member of junk food, and may even be the leader of junk food
-
at least
pizzas delivered to your home by supermarket shelves or takeaway delivery
.Historically, small ingredients, bread, tomatoes and a little cheese, have combined to form a traditional, healthy food, but many of today's
pizzas
contain two new ingredients that pose a health hazard

salts and saturated fatty acids.However,
pizzas
and many other foods with questionable nutrition can be a model of nutrition: the most brilliant example is

Stealth Health
", which
scientists say can achieve public health goals by adjusting the formulation of these foods, an adjustment that doesn't affect the food's original taste, so producers can keep it commercially successful.

Mike Lean
, a physician and nutritionist at
the University of Glasgow School of Medicine, said: ' traditional
pizzas
should be a low-fat food with at least some vegetables, mainly made from ingredients that are more cardiovascularly healthy.
” “
However, to improve shelf life,
pizza
higher fat and salt content than expected. Until now, no one has noticed that many of these essential vitamins and minerals are so low that they are not even enough. From a nutritional and health point of view
they
harmful junk food.
” “
Pizza is
widely consumed, and it is also used as a staple food, but the
pizza
's effects on human nutrition don't seem to have been studied.
”A team of scientists, including Dr
Emilie Combet
, dr
Amandine Jarlot
and Dr
Kofi Aidoo
from glasgow Caledonian University, studied the nutritional content and quality of
pizzas
and demonstrated that
pizzas
can once again form the basis of a fully nutritious diet.series of new pizza recipes have been developed, each containing
30% of the
. In other words, it's an ideal staple.team analyzed
25
margarita pizzas
the
25. These
pizzas
vary widely in calorie content, from
200
to
562
kca. It's rare to get close to the
600
kcale energy needed for a proper meal, so people tend to eat some extra food after
pizza
somewhat surprising is that only
6
of the
25,

pizzas
were detected to contain too much fat
(
35% of the total energy of >
)
,


pizzas
with excessive saturated fatty acids were detected, and only two claimed to have a satisfactory fat content of
(
11%) of <
's total energy
Most
pizzas
from cheese.
of the 25
pizzas
are significantly above the recommended limit, including
9

pizzas
containing more than
1,
grams per
600,
kca.several
pizzas
are within the recommended limit, but are not labeled low in salt or sodium, suggesting that the modified formula can still be commercially successful.a healthy and balanced meal, at least 45% of

energy intake should come from carbohydrates. Only five
pizzas
this requirement due to their high fat and protein content.most packages are free of vitamins and minerals, only five
pizzas
provide such details and three provide basic information. No pizza
can
the recommended values for iron, vitamin
C
and
vitamin
A. Only one can meet the iron content requirement, and two meet the
C
vitamin. Four met the requirements
vitamin
A, while only one met the calcium requirement.Professor Lean
said
"
some
pizzas
really unhealthy. While no tested
pizza
can meet all nutritional needs, some
pizzas
can meet many requirements, which tells us that if you want, it's possible to modify the formula to make
pizzas
nute more balanced without affecting flavor
-
, which is invisible health.
” To demonstrate how this can be done, the researchers teamed up with a food manufacturer to modify the current
pizza
formula: reduce salt additions, add whole wheat flour, add a small amount of Scottish seaweed to add flavor, vitamin
B12
, fiber, iron, vitamin
A
and iodine, and add red peppers to provide additional vitamin
C
. the ratio of dough to mozarella cheese was adjusted to an appropriate carbohydrate
/
fat
/
protein ratio and reduced saturated fatty acid content. After cooking,
pizza was
in the lab for a final analysis. , the team conducted a public tasting experiment in which both children and adults praised its taste and appeal. the world's first nutritionally balanced
pizza
which was then sold by food company
Eat Balanced.com
and all three flavors are available in UK supermarkets. Professor lean
:
"
" pizza
and other ready-to-eat meals should be nutritionally unbalanced, this is not true. We've proven that this can be done, and it doesn't hurt the flavor.
” “
So far, promoting healthy eating and nutrition education have had little impact on eating habits or health, while the so-called
'
nutrient supplement
'
has made the situation worse.
” “
We can't make our own food completely, so it's only a matter of time for manufacturers to take steps to make their products more suitable for human biology, and we've shown what to do. Instead of sneaking in additives like salt, they can boast about healthier ingredients that are good for consumers.
