It is commonly believed that a healthy diet is essential for having a healthy heart, but some people still scratch their heads.
A research article today aims to answer common questions about nutrition.
The Journal of the American College of Cardiology aims to guide cardiologists who, although patients view them as a source of information on cardiovascular regimens, do not have a history of cardiovascular disease. do not get much. According to Andrew Freeman, senior author of nutrition training, "the vast majority of cardiologists, and indeed many doctors, have very little practical knowledge about day-to-day nutrition," Dr. Freeman said.
"The goal here was really to tackle the things that people often ask us.
Cardiovascular health benefits based on controversial food evidence.

The authors looked at previous studies to see where the evidence came from specific foods such as dairy products, energy drinks and fermented foods, and nutrients. According to Dr. Freeman, the end result was that whole, plant-based foods, in which nutrients are delivered in their natural form, appear to be the healthiest.
"For example, people are very wary of whether there is sugar or carbohydrates in fruits and vegetables and that they do not really look bad. While if we extract and add sugar, these seem to be harmful.
"Same thing when we remove caffeine to make energy drinks, unlike the naturally occurring caffeine in coffee and tea. harmful. "
So, what is the verdict on the heart health credentials of each of the products studied by the authors? Let's take a look.
Dairy: The jury is still
Dairy products were the main contributor to saturated fats and salt in the American diet, found the authors.

dairy products are a good source of vitamins, minerals and proteins – but they may also contain "
" It was very widely shared on whether [dairy carries] injury or benefit, it is very confusing and disconcerting, "said Dr. Freeman
. All authors agree that the dairy appears to be the primary source of saturated fats and salt in the American diet. "
Getting a healthy intake of dairy products is possible if you make good choices according to Australian dietary guidelines of two and a half years serves one day, according to adv"
"It depends on the type of dairy products you are talking about ", she says.
"If you are talking about whole milk or skim milk, you are talking about it. about a 1% difference in fat … whereas if you're talking about the difference between, say, milk and cream, then you're talking about a 50% fat difference.
"As long as people stick to the types of dairy products like milk, yogurt and even cheese, they will be relatively safe in terms of cardiovascular disease."
Added sugars: Avoid

Fungi have been shown to reduce some of the conditions that sometimes appear alongside cardiovascular diseases, such as diabetes, metabolic diseases, and diabetes. 39; obesity. , the study found.
In addition, there is evidence that people who traded red meat for mushrooms remained satisfied after their meals.
So even though there was no clear, high-quality evidence directly linking fungi to better cardiovascular health, they will do you good in other respects, according to the authors.
Fermented Foods: Always Good!)
Fermented foods improve intestinal health, which has considerable benefits, but research in this area is still evolving, according to dietitian Melanie McGrice

In terms of the food patterns of the moment, fermentation should be among the most popular. But do fermented foods help your heart?
The evidence is not robust enough to recommend them systematically, but some studies suggest benefits for cardiovascular disease risk factors such as high blood pressure and cholesterol.
Ms. McGrice suspected the recent rise of fermented foods meant that the research had not yet caught up.
And although there is no clear evidence linking fermented foods to heart health, there was evidence of other health benefits
" What we are seeing now is that the intestinal microbiome has advantages. Ms. McGrice said, "There is definitely a connection between fermented foods and the improvement of the intestinal microbiome, which we find, is that the improvement of the intestinal microbiome has considerable benefits, but "
" And there may be benefits for cardiovascular diseases, but they have not been detailed yet.

Alongside food groups, the study also examined omega-3s and vitamin B12, both of which have been shown to have heart health benefits. What was the best way to get these nutrients, wondered the authors?
For omega-3s, found in both fish and plants, the evidence was unclear
"Omega-3s appear to be essential to diet food, the question is … what is the best source? Dr. Freeman said.
"And the jury is still on this point but when you look at the fish, even in the best places, they seem to be contaminated with more in addition. "
The authors concluded that one or the other source was probably beneficial to a whole food rather than a supplement.
As for B12, the authors recommended to supplement for people who were vitamin deficient.But they said that there was not much evidence to support the use of supplements as a preventative measure for cardiovascular disease
"And it's probably not like most people want to eat all their meals, but it's actually very feasible and very tasty."
"It's just a question of how clinicians, doctors, and their professionals know that patients are motivated to do that sort of thing."
