Scientists published myriad diet and nutrition studies in 2022, bringing to light surprising connections between what we eat and drink and our health.
It turns out
butter might not be as unhealthy as we thought, people who drink red wine have
less stomach fat than liquor-drinkers, and there are even more reasons to eat
bread.
Below are
seven things we learned about diet and health in 2022.
1. A variety of protein sources may lower the risk of high blood pressure.
A March
study in the journal Hypertension suggested that consuming a wider variety of
high-protein foods, such as beans, seafood, whole grains, and lean meat, may
help reduce the chance of developing high blood pressure.
According to
Insider's Gabby Landsverk, researchers looked at 12,117 Chinese people' eating
patterns and blood pressure over a median of six years of follow-up.
Compared to
people who ate just one or two types of protein, those who consumed four or
more were 66% less likely to develop high blood pressure.
2-Butter and full-fat dairy products
might be healthier than previously believed.
Butter and
other high-saturated-fat foods have traditionally been associated with poor
heart health due to their links to these conditions, but new research published
in Scientific Reports in August reveals that some saturated fats may actually
be beneficial to health.
According to
studies by Stephanie Venn-Watson, a veterinary epidemiology and public health
researcher, moderate doses of the saturated fat C15:0, which is present in butter
and full-fat dairy, may actually lower the risk of disease and enhance health
and wellbeing.
Years of
study on Navy dolphins revealed a resemblance between the animals' risk of
age-related sickness and that of people, according to Landsverk, who then
announced the findings on C15:0.
3. Whole grain bread's fiber content may be superior to that of fruits and vegetables for lowering the risk of heart disease.
A healthy
diet should include a variety of foods that are high in fibre.
Landsverk
said that a March study raises the possibility that whole grain fibre may have
even greater cardiovascular benefits than fruit and vegetable fibre.
A research
of 4,125 individuals published in March in JAMA Network Open found that
fiber-rich foods like dark bread, bran, and cereals (like oats) may help reduce
inflammation and the risk of heart disease.
4. A Mediterranean diet may lower the incidence of preeclampsia in pregnancy, especially for Black individuals.
Preeclampsia,
which is characterized by extremely high blood pressure and organ damage, is a
significant pregnancy condition with long-term repercussions on heart health.
According to
study that was published in April in the Journal of the American Heart
Association, a Mediterranean-style diet may, however, lower the risks,
especially in Black individuals.
The freshest
produce, olive oil, cereals, fish, nuts, and legumes are the top priorities of
the Mediterranean diet.
5. Eating two fish dishes each week is associated with a higher risk of skin cancer
Fish has
long been known to have many health benefits, including lowering cholesterol
and regulating blood sugar, but a study published in June in the journal Cancer
Causes and Control also discovered a link between eating two servings of fish
per week and an increased risk of developing skin cancer.
As noted by
Landsverk, fish like tuna may contain carcinogenic amounts of harmful mercury,
arsenic, and other pollutants.
More
research is required, the experts added, although it can still be a part of a
balanced diet.
6. Compared to alcohol or beer consumers, red wine drinkers have less belly fat.
According to
a study published in the February issue of the journal Obesity Science and
Practice, those who drink red wine have less belly fat than people who drink beer,
white wine, or liquor.
Red wine
drinkers were shown to have less visceral fat, which surrounds the abdominal
organs and is associated with a higher risk of cardiovascular disease and
metabolic syndrome.
According to
qualified dietician Rhiannon Lambert, the health dangers of alcohol use
currently outweigh any potential benefits.
7. Compared to women who eat meat, vegetarians are more likely to suffer hip fractures.

A study that
was published in BMC Medicine in August found that vegetarian women had a higher
risk of hip fractures as they aged than meat-eaters.
Vegetarians
had a third higher risk of breaking a hip than people who frequently consumed
meat, according to research that examined data from more than 26,000 women
between the ages of 35 and 69 over a 22-year period.
Researchers
suggested that nutritional deficits or the typical lower BMI of such women
could be contributing factors.
