5 Foods That 'Used to' Be Bad for You … But Now Are Considered an Essential Part of a Healthy Diet
Nutritional guidelines and recommendations are constantly changing in the light of new research. It can be difficult to keep up with which foods are healthy and which aren’t. Here we look at five foods that have gone through the cycle of being the villains of nutritional science but are now, based on some old and some new science, apparently okay to eat again.
For a long time, eggs were thought to be bad for your heart. A large egg contains a hefty 185 mg of cholesterol. Dietary cholesterol was believed to contribute to high blood cholesterol levels. But for the last 20 years, nutrition and medical research has shown repeatedly that at normal intakes dietary cholesterol has very little influence on a person’s blood cholesterol levels.
Although it’s taken a while, nutrition experts are now correcting the record for eggs and other foods that contain cholesterol (such as chicken liver and shellfish) by removing it as a nutrient of concern from dietary guidelines. Eggs are an excellent source of protein, healthy fats and several vitamins and minerals.
2. Fat Spreads
The story of fat spreads, such as margarine and butter, is probably one of the most confusing stories in nutrition. The origin of margarine, which is made from vegetable fat, dates back to the mid-1800s. Since that time, margarine has replaced butter as the fat spread of choice in most developed countries. This switch was driven by the lower price of margarine compared with butter as well as recommendations from health professionals to eat less saturated fat in order to prevent coronary heart disease (CHD).
While this switch away from saturated fats began to show reduced CHD incidence in the population, researchers also identified an independent link between trans fat (a fat produced when partially hydrogenating vegetable fats to make margarines) intake and CHD. Since this link between trans fat and CHD was confirmed by multiple studies regulatory agencies around the world have sought to eliminate trans fats from the diet.
The food industry was quick to respond and has been producing trans fat-free margarine for years now. However, there is still confusion among consumers as to whether vegetable, fat-based spreads are safe to eat. The short answer is yes, as long as the food label doesn’t list “partially hydrogenated vegetable oil” as an ingredient.
Modern vegetable oil-based fat spreads are a way to replace dietary saturated fat while increasing polyunsaturated fat—a dietary change that has been shown to reduce CHD in large cohort studies.
Potatoes are one of the few vegetables considered to be unhealthy. Because they’re a high glycemic index food they tend to get lumped in with foods made from refined carbohydrates as foods to avoid. But potatoes are a rich source of carbohydrates, vitamin C, some B vitamins and trace minerals.
How you prepare potatoes also changes the aspects of those starches that get a bad rap. Cooking and cooling potatoes increases the amount of resistant starch in the potatoes. This resistant starch then acts like dietary fibre which “resists” digestion in the gut, potentially having a positive impact on your gut bacteria.
Positive aspects of dairy include the high protein and calcium content. Fat content and fat type are important when choosing dairy products as some contain high amounts of fat per serving and this fat tends to be high in saturated fat.
Although it’s best to avoid a diet high in saturated fat (a risk factor for CHD), regularly consuming dairy products doesn’t need to be a concern if your overall calorie intake and fat intake is healthy. Because there are numerous studies that point toward both the healthy and unhealthy aspects of dairy it is difficult to recommend specific intakes or types of dairy foods for improving health. The recent updates to the UK Eat Well Plate still promotes dairy foods as part of a healthy diet, as long as the dairy choices are lower in fat.
5. Raw Nuts and Nut Butters
Nuts also get a bad reputation for being high in fat and high in calories, leading some to suggest they should be avoided by anyone looking to lose weight. But there is mounting evidence to suggest that raw nuts are key to a healthy diet and maintaining healthy body weight. A recent study, published in the British Journal of Nutrition, showed that eating raw nuts reduces death from all causes, cardiovascular diseases, coronary heart disease and sudden cardiac death.
Although studies are still ongoing to determine what components of tree nuts are promoting these positive health outcomes, we already know the nutritional benefits. Raw nuts contain protein, healthy fats (low saturated fat and high monounsaturated and polyunsaturated fat), dietary fiber and micronutrients.
Nut butters, such as peanut butter, can also be part of a healthy diet. The fat in peanut butter has a healthy profile and peanut butter is also an excellent source of protein, fiber, vitamin B6 and magnesium. Some recent evidence has shown increased weight loss for people that replace less healthy proteins, such as processed meats, with peanut butter.
Nut and nut butter consumption can be a part of a healthy diet, but you need to be mindful of the calories.
Remember, when it comes to food and health: all foods fit into a healthy diet. Don’t fall into the trap of believing in “superfoods” or “food villains.” Enthusiastic consumption of one particular “superfood” can be worse than consuming a so called “food villain.”

1. Stay Informed<p>A first order of business in pet evacuation planning is to understand and be ready for the possible threats in your area. Visit <a href="https://www.ready.gov/be-informed" target="_blank">Ready.gov</a> to learn more about preparing for potential disasters such as floods, hurricanes, and wildfires. Then pay attention to related updates by tuning <a href="http://www.weather.gov/nwr/" target="_blank">NOAA Weather Radio</a> to your local emergency station or using the <a href="https://www.fema.gov/mobile-app" target="_blank">FEMA app</a> to get National Weather Service alerts.</p>
2. Ensure Your Pet is Easily Identifiable<p><span>Household pets, including indoor cats, should wear collars with ID tags that have your mobile phone number. </span><a href="https://www.avma.org/microchipping-animals-faq" target="_blank" rel="noopener noreferrer">Microchipping</a><span> your pets will also improve your chances of reunion should you become separated. Be sure to add an emergency contact for friends or relatives outside your immediate area.</span></p><p>Additionally, use <a href="https://secure.aspca.org/take-action/order-your-pet-safety-pack" target="_blank" rel="noopener noreferrer">'animals inside' door/window stickers</a> to show rescue workers how many pets live there. (If you evacuate with your pets, quickly write "Evacuated" on the sticker so first responders don't waste time searching for them.)</p>
3. Make a Pet Evacuation Plan<p> "No family disaster plan is complete without including your pets and all of your animals," says veterinarian Heather Case in <a href="https://www.youtube.com/watch?v=Q9NRJkFKAm4" target="_blank">a video</a> produced by the American Veterinary Medical Association.</p><p>It's important to determine where to take your pet in the event of an emergency.</p><p>Red Cross shelters and many other emergency shelters allow only service animals. Ask your vet, local animal shelters, and emergency management officials for information on local and regional animal sheltering options.</p><p>For those with access to the rare shelter that allows pets, CDC offers <a href="https://www.cdc.gov/healthypets/emergencies/pets-in-evacuation-centers.html" target="_blank">tips on what to expect</a> there, including potential health risks and hygiene best practices.</p><p>Beyond that, talk with family or friends outside the evacuation area about potentially hosting you and/or your pet if you're comfortable doing so. Search for pet-friendly hotel or boarding options along key evacuation routes.</p><p>If you have exotic pets or a mix of large and small animals, you may need to identify multiple locations to shelter them.</p><p>For other household pets like hamsters, snakes, and fish, the SPCA recommends that if they normally live in a cage, they should be transported in that cage. If the enclosure is too big to transport, however, transfer them to a smaller container temporarily. (More on that <a href="https://www.spcai.org/take-action/emergency-preparedness/evacuation-how-to-be-pet-prepared" target="_blank" rel="noopener noreferrer">here</a>.)</p><p>For any pet, a key step is to establish who in your household will be the point person for gathering up pets and bringing their supplies. Keep in mind that you may not be home when disaster strikes, so come up with a Plan B. For example, you might form a buddy system with neighbors with pets, or coordinate with a trusted pet sitter.</p>
4. Prepare a Pet Evacuation Kit<p>Like the emergency preparedness kit you'd prepare for humans, assemble basic survival items for your pets in a sturdy, easy-to-grab container. Items should include:</p><ul><li>Water, food, and medicine to last a week or two;</li><li>Water, food bowls, and a can opener if packing wet food;</li><li>Litter supplies for cats (a shoebox lined with a plastic bag and litter may work);</li><li>Leashes, harnesses, or vehicle restraints if applicable;</li><li>A <a href="https://www.avma.org/resources/pet-owners/emergencycare/pet-first-aid-supplies-checklist" target="_blank">pet first aid kit</a>;</li><li>A sturdy carrier or crate for each cat or dog. In addition to easing transport, these may serve as your pet's most familiar or safe space in an unfamiliar environment;</li><li>A favorite toy and/or blanket;</li><li>If your pet is prone to anxiety or stress, the American Kennel Club suggests adding <a href="https://www.akc.org/expert-advice/home-living/create-emergency-evacuation-plan-dog/" target="_blank" rel="noopener noreferrer">stress-relieving items</a> like an anxiety vest or calming sprays.</li></ul><p>In the not-unlikely event that you and your pet have to shelter in different places, your kit should also include:</p><ul><li>Detailed information including contact information for you, your vet, and other emergency contacts;</li><li>A list with phone numbers and addresses of potential destinations, including pet-friendly hotels and emergency boarding facilities near your planned evacuation routes, plus friends or relatives in other areas who might be willing to host you or your pet;</li><li>Medical information including vaccine records and a current rabies vaccination tag;</li><li>Feeding notes including portions and sizes in case you need to leave your pet in someone else's care;</li><li>A photo of you and your pet for identification purposes.</li></ul>
5. Be Ready to Evacuate at Any Time<p>It's always wise to be prepared, but stay especially vigilant in high-risk periods during fire or hurricane season. Practice evacuating at different times of day. Make sure your grab-and-go kit is up to date and in a convenient location, and keep leashes and carriers by the exit door. You might even stow a thick pillowcase under your bed for middle-of-the-night, dash-out emergencies when you don't have time to coax an anxious pet into a carrier. If forecasters warn of potential wildfire, a hurricane, or other dangerous conditions, bring outdoor pets inside so you can keep a close eye on them.</p><p>As with any emergency, the key is to be prepared. As the American Kennel Club points out, "If you panic, it will agitate your dog. Therefore, <a href="https://www.akc.org/expert-advice/home-living/create-emergency-evacuation-plan-dog/" target="_blank" rel="noopener noreferrer">pet disaster preparedness</a> will not only reduce your anxiety but will help reduce your pet's anxiety too."</p>
Evacuating Horses and Other Farm Animals<p>The same basic principles apply for evacuating horses and most other livestock. Provide each with some form of identification. Ensure that adequate food, water, and medicine are available. And develop a clear plan on where to go and how to get there.</p><p>Sheltering and transporting farm animals requires careful coordination, from identifying potential shelter space at fairgrounds, racetracks, or pastures, to ensuring enough space is available in vehicles and trailers – not to mention handlers and drivers on hand to support the effort.</p><p>For most farm animals, the Red Cross advises that you consider precautionary evacuation when a threat seems imminent but evacuation orders haven't yet been announced. The American Veterinary Medical Association has <a href="https://www.avma.org/resources/pet-owners/emergencycare/large-animals-and-livestock-disasters" target="_blank">more information</a>.</p>
Bottom Line: If You Need to Evacuate, So Do Your Pets<p>As the Humane Society warns, pets left behind in a disaster can easily be injured, lost, or killed. Plan ahead to make sure you can safely evacuate your entire household – furry members included.</p>
