These are the worst frozen foods for your health, experts say



NEWYou can now listen to Fox News articles!

Many of us head first to the frozen foods aisle when we go grocery shopping. Could this common practice be sabotaging our health? Like most things on the nutrition front, it depends.

“When it comes to frozen foods, several nutrients are of major concern for heart health; salt, sugar and unhealthy fats. Not only are foods that contain an excess of these nutrients inflammatory, they are also key drivers for obesity, heart disease, high blood pressure and diabetes,” said registered dietitian Angela L. Lago, also known as “The Mental Wellness Dietitian.”

The American Heart Association (AHA) recommends no more than 2,300 milligrams of sodium per day.

The “ideal limit” is no more than 1,500 mg per day for most adults, especially those who have high blood pressure, according to the AHA.

Lago said that some frozen foods like frozen vegetables, fruits and whole grain products are not all bad, though there are categories individuals looking to improve or protect heart health should avoid.

“When frozen food is the only choice, compare food labels and choose the product with less salt, sugar and trans fat,” she said, noting that processed, packaged foods make up 70% of the salt in average Americans’ diets.


“Ultra-processed foods are not only loaded with sugar, fats, and/or salt, but also include preservatives and artificial colors and flavors that allow the products to have a longer shelf life. These ultra-processed foods are associated with a greater risk of cardiovascular disease,” Lago, pointing to the 2021 dietary guidance to improve cardiovascular health from the AHA.

Packaged frozen dinners

Pointing to a review published in the International Journal of Molecular Sciences about sodium intake and heart failure, Kaleigh McMordie, a registered dietitian nutritionist of the, said, “While there are certainly healthier options available among single-serve frozen dinners, many are notoriously unhealthy. One of the main reasons is the sodium level. Frozen dinners can have upwards of 1,000 mg of sodium, often from sodium-based preservatives, contributing more than half a day’s recommended amount of sodium.”


“Too much sodium, especially from frozen and packaged foods, is a contributing factor to hypertension, stroke, and heart disease,” she added. “Frozen dinners are also usually severely lacking in vegetables.”

McMordie said that if you must buy a frozen dinner, read the label to find a lower sodium option and pair it with a salad or other vegetable side.

(You may want to split it into multiple portions, too, even if it’s marked as a single-serve meal.)


Frozen pizza roll snacks

A combination of icky additives, calories galore, and excess fat and sodium is the name of the game when it comes to most frozen pizza roll snacks.

“These snacks are far from a slice of pizza. They’re typically filled with sodium, fat, lots of additives for preservation, such as nitrates and phosphates and even imitation cheese,” said McMordie, highlighting a study published in the German Medical Association’s science journal, Deutsches Ärzteblatt international, about the potential of added phosphates to damage heart health.

“I recommend having a slice of real, thin crust pizza if you’re craving pizza.”

Frozen pizza can be just as bad as frozen roll pizza snacks.

Frozen pizza can be just as bad as the frozen roll pizza snacks discussed above.

“Frozen pizza is a high-calorie food that is loaded with calories, salt and fat. While there are healthier choices, such as thin crust options topped with vegetables, most frozen pizzas have a thicker refined grain crust, topped with cheese and processed meat ,” said Lago.


As Lago explained, frozen pizza checks several of the boxes for evidence-based dietary practices you should avoid in order to promote cardiovascular health, such as:

-Choose foods made primarily with whole grains rather than refined grains
-Choose healthy choices of protein, lean cuts and avoid processed forms
-Choose foods with little or no salt
-Choose low-fat or fat-free dairy products

Frozen pot pies

We know they can taste good, but not so good that it’s worth compromising your health.

“While frozen pot pies may provide us comfort, these are one of the highest calorie and fat-containing frozen foods,” said Allison Tallman, registered dietitian at

“There is limited beneficial nutritional value coming from this product. The excess calories and fat may lead to weight gain,” she continued, adding that weight gain can lead to an array of diseases like heart disease, high cholesterol, metabolic syndrome or type 2 diabetes.

Frozen corn dogs

This state fair staple should be enjoyed – occasionally – at such events, and not stored in your freezer for easy access whenever a corn dog craving strikes.

“Processed meats, such as sausages, bacon and hot dogs, are some of the worst offenders when it comes to heart health, mostly because of the sodium content and chemical preservatives in them. Studies have linked higher processed meat intake to higher risk of heart disease and diabetes,” said McMordie.


“Frozen corn dogs not only have highly processed meat, but that meat is also wrapped in a sugary batter devoid of any real nutrients then fried before being frozen,” she elaborated, suggesting people limit processed meat intake to less than one serving per week for heart health.

Frozen french fries

When buying frozen French fries, be sure to scan the ingredients list and look for added oils and salt.

Be sure to scan the ingredients list when buying these and look for added oils and salt.

“When you order French fries, you’re also getting a helping of heaping of fat and calories,” said Janet Coleman, registered dietitian of She noted that an order of McDonald’s fries contains 530 calories and 22 grams of fat; at KFC, a large order of fries has 610 calories and 25 grams of fat; and Wendy’s Natural-Cut Fries have 610 calories and 28 grams of fat.

Frozen French fries you buy at the supermarket can have a similarly poor nutrition profile, so buyer beware.

Frozen calzones

Tallman puts this on the list due to the high amounts of sodium found in the product.

“These calzones often have about 1,700 mg of sodium in just one serving! An excess of sodium in the diet can lead to increased blood pressure,” she said.

Considering you can hit your daily sodium allotment in just one frozen calzone, it may be worth a pass.

Sweet and Sour Chicken

“Sweet and sour chicken is a good source of protein (from the chicken), but is secretly packed with a ton of added sugar,” said Tallman. “Some have upward of 40 g of added sugar per serving. Added sugar is negative for your health because it can increase risk of obesity, which leads to heart disease.”

If you’re craving sweet and sour chicken, try making it from scratch; that way, you can control exactly how much sugar you use.

Frozen toaster pastries

Add this popular breakfast item to your list of foods to avoid in the frozen foods’ aisle.

“Frozen breakfast pastries consist of several forms of highly processed carbohydrates and sugar with no real nutritional value, not to mention all the chemical preservatives. Regular intake of these kinds of highly processed foods — high in refined white flour, refined sugar and high fructose corn syrup — is associated with a poor lipid profile,” said McMordie, referencing a study published in Current Atherosclerosis Reports on carbohydrates and blood lipids.

“High triglyceride and LDL cholesterol levels in the blood, caused by high refined carb intake, is a major risk factor for heart disease. Skip the toaster pastries and opt for a breakfast that has a balance of healthy fat, protein, and carbohydrates from whole grains or fruit.”

How about whipping up some nutritious apple pie breakfast tacos?


Frozen Baked Goods

“Frozen baked goods, such as cinnamon rolls, biscuits, waffles, and dessert items are loaded with salt, sugar, and fat,” says Angela L. Lago MS, RDN, LDN.

There are other frozen sweets you may want to skip.

“Frozen baked goods, such as cinnamon rolls, biscuits, waffles and dessert items are loaded with salt, sugar and fat,” said Lago, nodding at a 2019 study published in BMJ about the connection between ultra-processed foods and the risk of heart illness.

“While they may be a convenient breakfast or sweet treat, these items should never be a staple in one’s diet,” Lago added. “Many times, even though you cannot taste the salt, it’s still there in many baked goods. Items in the frozen baked goods category are [also] often low in fiber and vitamin density.”

Protein Variety and Heart Health Are Linked, Study Finds



We’ve all found ourselves in the habit of eating the same three things over and over (…and over) again. When life gets busy, falling back on simple dishes that satisfy your tastebuds is the natural thing to do. But if you’re cooking up the same couple proteins on the regular, a new study published in the the journal Hypertension suggests that it may be time to introduce a few new varieties into your breakfasts, lunches, and dinners.

The study pulled existing data from over 12,000 participants who took part in a minimum of two rounds of the China Health and Nutrition Survey. Researchers sought to explore the relationship between hypertension—or high blood pressure—and the variety and quantity of proteins from eight major dietary sources consumed by participants. (Study participants were an average age of 41 years old.)

Researchers measured protein intake by looking at three consecutive days of eating, scoring each round based on the number of protein varieties consumed (including legumes, fish, eggs, whole grains, refined grains, processed and unprocessed red meat, and poultry).

The results? “Among ‘just the right amount’ consumers of protein, those eating the greatest variety of protein had a the lowest blood pressure,” explains John Higgins, MD, a sports cardiologist with McGovern Medical School at the UT Health Science Center at Houston. Notably, those who ate the least and the most amount of protein were at the greatest risk for developing high blood pressure, while those who ate the greatest variety of protein were 66 percent less likely to end up developing hypertension between the rounds of the survey .

“The heart health message is that consuming a balanced diet with proteins from various different sources, rather than focusing on a single source of dietary protein, may help to prevent the development of high blood pressure.” — Xianhui Qin, MD, study author

Although the survey results sound complicated—and, hey, they were—the takeaway is simple: “The heart health message is that consuming a balanced diet with proteins from various different sources, rather than focusing on a single source of dietary protein, may help to prevent the development of high blood pressure,” Xianhui Qin, MD, the study author, said in a press release. In other words: Mix it up! Spin the protein wheel of fortune and try something new.

Related Stories

If you’re not quite sure where to start with upping your protein game, Dr. Higgins recommends looking at your consumption on a daily basis. “The American Heart Association recommends eating no more than about 5.5 ounces of protein daily, about one to two servings, from healthy sources such as plants, seafood, low-fat or fat-free dairy products and some lean meats and poultry,” he says. “The best proteins are lean proteins including beans, soy or tofu, fish, skinless chicken, very lean meat, and low-fat dairy products. Avoid proteins that say ‘hydrogenated’ on label or contain high levels of trans fats or saturated fats. “

Of course, there’s always room in your eating plan for less nutritional proteins, too—just try to incorporate these lean sources when you can, and ask your doctor if you have questions about what dietary habits are right for your particular health status and family history .

Best Diet Books

    How to Choose a Diet Book

    If you’re looking to switch up your diet, the first thing you should ask yourself is why. What exactly do you want out of a diet?

Eating different kinds of protein protects against hypertension: New study



Despite all this talk that more Australians are toying with vegetarianism, and despite the endless drum-beating about red meat giving you cancer and a dodgy heart, we continue to have one of the world’s highest levels of meat consumption.

Analysis published in December found Australians eat about 95 kilograms of meat per capita every year. The global average is 35 kilograms.

The article, ‘The Evolution of Urban Australian Meat-Eating Practices’, argues our meat-eating habits are driven by a blocky culture, an association with social status, a perception that plant-based diets are inadequate and lame, and ignorance about cooking legumes and tofu.

On the other hand, the authors point to a survey that found almost 20 per cent of those sampled “identified as meat-reducers”.

Furthermore, the authors say, 87 percent “of the meat reducer segment reported consuming a meat-free dish as their main meal at least once a week”.

They point to another survey that found almost 20 per cent described themselves as “flexitarian”, which is cool.

But it may not translate to more lentils, nuts, whole grains, fish and dairy hitting the dinner table as new favorite sources of protein.

A new study found why we need variety

Chinese researchers found that “eating protein from a greater variety of sources is associated with a lower risk of developing high blood pressure”.

Good to know because blood pressure is literally out of control in Australia.

One in three adults – more than six million Australians – has high blood pressure.

Of those afflicted, only 32 per cent have their hypertension under control. That leaves about four million Australians as ticking time bombs.

In December, in the Medical Journal of Australia, Professor Alta Schutte, Professor of Cardiovascular Medicine at UNSW Sydney, called for a national taskforce to tackle the issue.

By improving the control of hypertension, the risks of coronary heart disease, dementia and cerebrovascular disease will be substantially reduced.

The Chinese study suggests changing your diet will go some way to solving the problem.

the study

“Nutrition may be an easily accessible and effective measure to fight against hypertension. Along with fat and carbohydrates, protein is one of the three basic macronutrients,” said study author Dr Xianhui Qin, of the National Clinical Research Center for Kidney Disease at Nanfang Hospital, Southern Medical University in Guangzhou, China.

The study authors analyzed health information for nearly 12,200 adults (average age 41), who had taken part in multiple rounds of the China Health and Nutrition Survey from 1997 to 2015.

Over three days in the same week, participants shared what they had eaten.

They were given a protein “variety score” based on the different sources of protein they’d eaten: whole grains, refined grains, processed red meat, unprocessed red meat, poultry, fish, egg and legumes.

One point was given for each source of protein, with a maximum variety score of 8. The researchers then evaluated the association for new onset hypertension in relation to the protein variety score.

New-onset hypertension was defined as blood pressure greater than or equal to 140 mm Hg/90 mm Hg, the use of blood pressure-lowering medicine, or self-reporting that a physician had diagnosed high blood pressure.

The average follow-up time was six years.

The results

More than 35 per cent of the participants developed new-onset high hypertension during the follow-up.

Compared to participants with the lowest variety score for protein intake (1), those with the highest variety score (4 or higher) had a 66 per cent lower risk of developing high blood pressure.

The amount of protein eaten was also a factor. Consumption was divided into five categories, from least to most intake.

The researchers found that “people who ate the least amount of total protein and those who ate most protein had the highest risk for new onset of hypertension”.

The researchers didn’t ask why a variety of proteins was more healthy. But nutritionists, doctors and health writers have banged on about it for years.

Lean red meat is high in quality protein but provides no fiber or healthy fats. Processed meats are high in saturated fats and salt and are the worst.

Fish is high in long-chain fatty acids, which are good for the brain. Lentils and whole grains are high in fibre.

Hand on heart, a bit of each during the week might stop you from carking it in the street. Which is just undignified and unmanly.
