5 “Healthy” Foods to Avoid for Biblical Health

QUICK SUMMARY

The top five “healthy” foods to avoid are industrial vegetable oils, artificial sweeteners, highly processed unfermented soy, conventional factory-farmed fish and meat, and store-bought fruit juice.

These foods are often sold with a health halo: “natural,” “heart healthy,” “low calorie,” “plant-based,” “high protein,” “sugar-free,” or “made with real fruit.” But when you look past the front label and read the ingredients, many of them are refined, ultra-processed, pesticide-exposed, sugar-heavy, stripped of fiber, or produced in ways that do not support Biblical health.

The better choice is simple: eat real food as close to the way God made it as possible. Choose whole fruit instead of fruit juice, traditional fermented soy instead of soy isolates, wild-caught fish and pasture-raised meats instead of factory-farmed proteins, natural sweeteners in moderation instead of artificial sweeteners, and quality fats like extra virgin olive oil, coconut oil, avocado oil, grass-fed butter, and ghee instead of cheap refined seed oils.

Americans have become too trusting in manufacturer food labels. Our grocery stores are now filled with “health foods” and “natural foods” that are anything but beneficial for us to consume. That’s why I’ve compiled this list of five healthy foods to avoid.

Most people today are absolutely confused about what to eat, what not to eat, and how to tell the difference between the two. This situation has become very serious because the front of the package is designed to sell, not to disciple your family into Biblical health.

We Have Been Misled About Healthy Food

A food label can sound healthy and still describe a product that is refined, ultra-processed, high in sugar, made with industrial oils, or stripped of the fiber and nutrients God placed in the whole food.

This is important: even the word “natural” does not mean what many families think it means. The FDA says it has not established a formal rule defining “natural” on food labels, and its longstanding policy focuses mainly on whether artificial or synthetic ingredients have been added. It does not automatically mean the food is organic, pesticide-free, non-GMO, minimally processed in the way families expect, or good for your health. (1)

Even the “healthy” claim on food packaging is a voluntary nutrient content claim with specific criteria. The FDA finalized an updated rule to better align the claim with current nutrition science, but this is still a label claim. It does not replace wisdom, discernment, or reading the ingredient list. (2)

A study in the British Journal of Nutrition suggests that one reason people are duped into believing unhealthy foods are good for them is the way foods are advertised. Researchers found that foods are often marketed in a broader “healthy” food context, which can make the advertised product look better than it really is. (3)

Put simply, marketers know how to borrow a health halo.

They put a sugary cereal beside strawberries. They put a bottle of juice beside whole fruit. They put “plant-based” on a processed soy dessert. They put “zero sugar” on a drink full of artificial sweeteners. They put “heart healthy” on oils that have been refined, deodorized, heated, and used throughout the processed-food supply.

Children are particularly misled by this faulty advertising.

The end result of this mass deception is the creation of an entire culture where each generation since the Baby Boomers has been basically eating out of a box and flocking to anything labeled “all-natural” without even a second thought.

And the research keeps confirming the concern. A 2024 umbrella review in BMJ found that greater exposure to ultra-processed foods was associated with a higher risk of adverse health outcomes, especially cardiometabolic, mental health, and mortality outcomes. (4)

Reality check: Biblical health is not about chasing labels. It’s about wisdom, stewardship, and learning to recognize food that supports the abundant life instead of stealing from it.

The Five Worst Health Foods

Americans have been convinced that countless food items are actually good for them because of false, misleading advertising. The five worst health foods and offenders are:

1. Vegetable Oils

Vegetable oils like canola, soybean, corn, cottonseed, and generic “vegetable oil” blends have been heavily marketed as the “heart healthy” solution to the rise in cardiovascular disease.

The direct answer: the worst vegetable oils to avoid are industrially refined seed oils, partially hydrogenated oils, margarine, shortening, and restaurant fryer oils. These oils are common in packaged snacks, fried foods, commercial salad dressings, mayonnaise, crackers, baked goods, and many “healthy” convenience foods.

Here’s the thing: not all fats are created equal, and not every oil that comes from a plant should be treated like a real-food staple.

For decades, partially hydrogenated oils were a major source of artificial trans fat in the food supply. The FDA has completed final administrative actions revoking uses of partially hydrogenated oils in foods because these oils are no longer considered GRAS for human food. (5)

That matters because trans fats raise LDL cholesterol, lower HDL cholesterol, and are associated with increased risk of heart disease, stroke, and type 2 diabetes. (6)

And the problem does not end with trans fats. When vegetable oils are repeatedly heated or used for high-temperature frying, research shows they can generate aldehydes and other oxidation products that raise health concerns. (7)

This is why industrial vegetable oils are one of the top “healthy” foods to avoid. They are sold as clean, modern, and heart-smart, but they are often highly refined and embedded throughout the processed-food system.

Common oils and products to limit or avoid:

• Canola oil
• Soybean oil
• Corn oil
• Cottonseed oil
• Generic “vegetable oil” blends
• Margarine
• Shortening
• Partially hydrogenated oils
• Restaurant fryer oils
• Packaged foods made with refined seed oils

Choose better fats instead:

• Extra virgin olive oil for salads, dips, dressings, and low-heat cooking
• Coconut oil for baking and medium-heat cooking
• Avocado oil for higher-heat cooking
• Grass-fed butter or ghee if tolerated
• Whole-food fats from avocados, olives, nuts, and seeds

Application: Check your pantry today. If you see canola, soybean, corn, cottonseed, “vegetable oil,” shortening, margarine, or partially hydrogenated oils on the ingredient label, start replacing those products with real-food alternatives.

2. Artificial Sweeteners

Recommended by many doctors and dietitians, artificial sweeteners are praised for being low on the glycemic index and supposedly diabetic-safe.

The direct answer: artificial sweeteners are not a free pass for health. They may reduce sugar and calories in the short term, but current research raises concerns about long-term use, gut microbiome effects, glycemic response, weight management, and cardiometabolic outcomes.

In 2023, the World Health Organization advised against using non-sugar sweeteners for weight control, stating that the evidence does not show long-term benefit for reducing body fat and that long-term use may have potential undesirable effects, including increased risk of type 2 diabetes, cardiovascular disease, and mortality in adults. (8)

A randomized human trial published in Cell found that saccharin and sucralose supplementation impaired glycemic responses in some healthy adults who did not normally consume non-nutritive sweeteners. The effects were person-specific and microbiome-dependent. (9)

Aspartame has also remained controversial. In 2023, IARC classified aspartame as “possibly carcinogenic to humans” based on limited evidence, while JECFA reaffirmed the acceptable daily intake. (10) That distinction matters, but so does the practical takeaway: these products are not the health miracle they were marketed to be.

That’s why we focus on natural sweeteners as often as possible and use them sparingly.

Artificial sweeteners to watch for:

• Aspartame
• Sucralose
• Saccharin
• Acesulfame potassium
• Neotame
• Artificially sweetened “diet” drinks
• “Sugar-free” desserts, yogurts, gums, and protein bars

Artificial sweeteners have been associated in various studies and reports with concerns such as:

• Changes in gut microbiome response
• Impaired glycemic response in some people
• Weight gain or difficulty with long-term weight control
• Cardiometabolic concerns
• Headaches or sensitivity reactions in susceptible people
• Ongoing questions about cancer risk for some sweeteners, depending on the specific compound and evidence type

Better options in moderation:

• Raw local honey
• Pure maple syrup
• Dates or date paste
• Monk fruit without unnecessary chemical additives
• Organic stevia leaf or cleaner stevia extracts
• Fruit used in whole-food recipes

Application: Don’t trade regular soda for diet soda and call it health. Start retraining your taste buds. Add berries, lemon, lime, mint, cucumber, or a tiny amount of natural sweetener to drinks and recipes while you transition away from overly sweet foods.

3. Unfermented Soy

If we were to take a survey and ask the average American citizen what the #1 health food item on the market is, tofu and soy products would most definitely be in the top 10.

You’ll find soy milk, soy ice cream, soy burgers, soy protein bars, soy shakes, soy yogurt, and soy-based dairy alternatives everywhere. This, folks, has been one of the great deceptions of the health food industry.

The direct answer: the soy foods to avoid are conventional, highly processed, unfermented soy products such as soy protein isolate, soy milk, soy desserts, soy burgers, and soy-based processed foods eaten as daily staples. Traditional fermented soy foods are a different category.

Why is soy bad for you? First of all, not all soy products are bad. That distinction is important.

For thousands of years, people in the Far East have traditionally eaten fermented soy foods like natto, miso, and tempeh. Research from Japan found that higher intake of fermented soy products was associated with lower mortality risk. (11)

But eating traditional fermented soy is not the same thing as drinking soy milk by the gallon or building your diet around processed soy protein isolate.

Reality check: our position is not that every soy food is poison. Current research on whole soy is more nuanced than the old health-food debate made it sound. For example, Mayo Clinic notes that eating soy foods does not raise breast cancer risk and may lower risk, while the safety of soy supplements is less clear. (12)

Our concern is with highly processed, unfermented, GMO, conventionally grown soy that is promoted as a daily health staple.

According to USDA ERS data, herbicide-tolerant soybean adoption reached 96 percent of U.S. soybean acreage in 2024 and remained at 96 percent in 2025. (13) That means if you are buying conventional soy products, you are very likely buying soy grown in a system built around herbicide-tolerant crops.

Soy can also be an issue for some people with thyroid concerns. A review in Thyroid found little evidence that soy foods or isoflavones adversely affect thyroid function in iodine-replete people with normal thyroid function, but soy foods may inhibit absorption of thyroid hormone medication and could increase the dose required by some hypothyroid patients. (14)

So, yes, we still recommend caution with conventional unfermented soy. But we want to be precise: the biggest concern is not a small serving of organic fermented soy; it is the processed-soy lifestyle that has been sold as a shortcut to health.

Soy products to limit or avoid:

• Conventional soy milk
• Soy protein isolate
• Soy-based protein powders
• Soy burgers and processed meat substitutes
• Soy ice cream and soy desserts
• Conventional tofu eaten as a daily staple
• Packaged foods made with soybean oil or soy protein fillers

Better choices:

• Organic fermented soy, such as natto, miso, and tempeh
• Organic tofu occasionally if tolerated
• Coconut milk, almond milk, or hemp milk as dairy alternatives
• Whole-food protein from beans, lentils, pasture-raised eggs, wild fish, grass-fed meats, nuts, and seeds

Application: If soy is a major part of your daily diet, start by swapping processed soy products for whole-food proteins. If you use soy, choose organic and fermented first. If you take thyroid medication, ask your practitioner how to time soy foods away from your medication.

4. Conventional Fish and Meat

Like soy, not all fish and meat are bad for you; it is factory farm-raised fish and non-organic meats farmed by conventional methods that raise the biggest concerns.

Even salmon, widely regarded as one of the healthiest protein and omega-3 choices, deserves a closer look when farm raised.

The direct answer: conventional factory-farmed fish and meat are “healthy” foods to avoid because sourcing affects contaminant exposure, fatty acid profile, feed quality, antibiotic use, animal welfare, and environmental burden.

Historically, the Environmental Working Group reported that farmed salmon samples from U.S. grocery stores contained far higher dioxin-like PCB levels than wild salmon. (15) Current data are more nuanced because farming practices, feed, country of origin, and contaminant monitoring vary. An updated review comparing farmed, escaped, and wild Atlantic salmon still shows meaningful differences in fat content, fatty acids, dioxins, PCBs, and selected heavy metals. (16)

In other words, the answer is not simply “fish is good” or “fish is bad.” The answer is: sourcing matters.

And we see a similar picture with factory-farmed beef, pork, and poultry. It is not just about the animal; it is about the feed, living conditions, drug exposure, waste burden, environmental contamination, and the quality of the final food.

Antibiotic resistance is one major concern. The CDC states that antimicrobial-resistant germs can spread between animals, in their environments, during transport, and during processing. (17) A 2024 American Academy of Pediatrics report states that evidence supports a link between antibiotic use in food-producing animals and antibiotic-resistant infections in humans. (18)

Conventional animal foods to limit or avoid:

• Farm-raised fish from poor-quality sources
• Factory-farmed beef, pork, and poultry
• Processed lunch meats
• Hot dogs and conventional sausages
• Meat from animals raised on GMO feed
• Cheap fish products with vague sourcing

Better choices:

• Wild-caught salmon, sardines, anchovies, and smaller fatty fish
• Grass-fed and grass-finished beef
• Pasture-raised poultry and eggs
• Organic meats when possible
• Local farms with transparent practices
• Plant-forward meals with clean protein as a supporting feature

Application: You don’t need to eat large portions of meat every day to be healthy. Build your plate around vegetables, herbs, spices, healthy fats, and clean protein. Quality matters more than quantity.

5. Fruit Juice

Most people are floored to learn that many store-bought fruit juices are not the health food they have been told they are.

The direct answer: fruit juice is not the same as whole fruit. Even 100 percent fruit juice can deliver a large sugar load without the fiber and food structure that make whole fruit so beneficial.

To be fair, fresh fruit and vegetable juice can contain vitamins, minerals, and bioactive compounds. A small amount of fresh juice, especially vegetable-heavy juice, is not the same thing as a neon-colored fruit “drink” filled with added sugar, artificial colors, and flavorings.

But here’s the problem: juice removes or dramatically reduces the fiber and food matrix that help whole fruit digest more slowly and keep you full. Without that fiber-rich structure, it is easy to drink the sugar from several pieces of fruit in just a few minutes.

A 2024 systematic review and meta-analysis published in JAMA Pediatrics found that one serving per day of 100 percent fruit juice was associated with BMI gain among children. Findings in adults suggested that excess calories may mediate the weight effect. (19)

The American Academy of Pediatrics states that fruit juice offers no nutritional benefit over whole fruit for children older than 12 months, and whole fruits provide fiber and other nutrients. (20)

Most store-bought juices are also pasteurized. Pasteurization can reduce food safety risks, but it does not make juice equivalent to whole fruit. You still lose the chewing, fiber, satiety, and slow digestion that come with eating the whole food.

Fruit juice problems to watch for:

• Large sugar load in a small serving
• Little to no fiber compared with whole fruit
• Easy overconsumption
• Blood sugar spikes, especially when consumed alone
• “Fruit drinks” and “juice cocktails” with added sugars
• Kids sipping juice throughout the day

Think of it this way: fresh, raw, whole fruit contains a considerable amount of soluble and insoluble fiber, which aids digestion and helps us feel full. That fiber also feeds the healthy bacteria in our gut.

If you skip eating the fruit and drink the juice only, you are robbing your body of the fiber. This is why excessive juice drinkers often experience blood sugar swings, hunger, diarrhea, and other GI issues.

That said, learning how to make your own juice at home can be helpful when done wisely. Keep it vegetable-heavy, use fruit sparingly for flavor, and enjoy it in moderation as part of a real-food lifestyle.

Better choices:

• Whole fruit
• Fruit smoothies that keep the fiber intact
• Vegetable-heavy green juice in small amounts
• Infused water with lemon, berries, cucumber, herbs, or mint
• Herbal tea, sparkling mineral water, or clean homemade electrolyte drinks

Application: Replace daily juice with whole fruit for two weeks and watch how your cravings, appetite, digestion, and energy respond.

How to Spot Fake Health Foods

You can’t believe everything you read on food labels or even on the Internet. The blessing of free speech has been adulterated with false, greedy advertisements, and many “health” blogs are nothing more than a way to promote product sales.

The direct answer: the fastest way to spot fake health foods is to ignore the front label and read the ingredient list first.

So what should you do?

Start with the ingredient list, not the marketing claim.

Ask these questions before you buy:

• Would my great-grandparents recognize this as food?
• Is this a whole food or a processed food product?
• Does the front label use buzzwords like “natural,” “plant-based,” “keto,” “low calorie,” “protein,” “gluten-free,” or “made with real fruit” to distract me from the ingredients?
• Does it contain industrial oils, artificial sweeteners, refined sugar, soy protein isolate, synthetic colors, or preservatives?
• Is this food nourishing my family or simply satisfying a craving?
• Could I make a cleaner version at home?

This is where Biblical health gets practical. We steward our bodies by choosing foods that support life, not foods that merely wear a healthy costume.

We do not need perfection. We need discernment.

A healthy lifestyle is not built on fear. It is built on wisdom, consistency, and a willingness to keep learning.

What to Eat Instead

The best way to avoid fake health foods is to replace them with real foods that nourish your body, support your gut, stabilize your energy, and help your family experience the abundant life.

The direct answer: eat real food as close to the way God made it as possible. Build your meals around vegetables, herbs, spices, whole fruit, clean protein, healthy fats, fermented foods, and fiber-rich plant foods.

Simple swaps for the five worst health foods:

• Instead of vegetable oils: use extra virgin olive oil, coconut oil, avocado oil, grass-fed butter, or ghee.
• Instead of artificial sweeteners: use raw honey, maple syrup, dates, monk fruit, or stevia in small amounts.
• Instead of processed soy: choose organic fermented soy occasionally, or use whole-food proteins like beans, lentils, eggs, wild fish, grass-fed meat, nuts, and seeds.
• Instead of conventional meat and fish: choose wild-caught fish, pasture-raised eggs, grass-fed beef, organic poultry, and local farms with transparent practices.
• Instead of fruit juice: eat whole fruit, make fiber-rich smoothies, or enjoy vegetable-heavy fresh juice in moderation.

Application: Do not try to overhaul your entire kitchen in one day. Start with one category. Replace your cooking oils first, then remove artificial sweeteners, then clean up your protein sources, then reduce juice and processed soy. Small obedient steps become a lifestyle.

This is Biblical health in real life: nutrition, movement, sleep, stress relief, prayer, a lower toxic burden, and wise daily habits working together. Essential oils can be a beautiful part of that lifestyle, but there’s no oil for a diet built on fake food. Food matters. Stewardship matters. Your family is worth the effort.

Healthy Foods to Avoid FAQs

What are the top healthy foods to avoid?

The top healthy foods to avoid are industrial vegetable oils, artificial sweeteners, highly processed unfermented soy, conventional factory-farmed fish and meat, and store-bought fruit juice. These foods often look healthy because of marketing claims, but many are refined, processed, sugar-heavy, stripped of fiber, or produced in ways that do not support long-term wellness.

Why are some “healthy” foods actually unhealthy?

Some “healthy” foods are unhealthy because the marketing is better than the ingredients. Labels like “natural,” “plant-based,” “low calorie,” “heart healthy,” or “made with real fruit” can distract you from refined oils, artificial sweeteners, added sugars, soy isolates, preservatives, and ultra-processed ingredients.

Is canola oil healthy?

We do not recommend canola oil as a daily staple. It is usually highly refined, commonly comes from herbicide-tolerant crops, and is used throughout the processed-food supply. The biggest concerns are refined seed oils in packaged foods, restaurant fryers, and products that contain hydrogenated or repeatedly heated oils. Choose extra virgin olive oil, coconut oil, avocado oil, grass-fed butter, or ghee instead.

Are artificial sweeteners better than sugar?

Not necessarily. Artificial sweeteners may reduce calories in the short term, but they do not teach your taste buds to enjoy real food. The World Health Organization advises against using non-sugar sweeteners for weight control because the evidence does not show long-term body-fat benefit and suggests possible undesirable long-term effects. Use natural sweeteners sparingly and focus on reducing your overall need for sweet foods.

Is soy bad for you?

Not all soy is bad. Traditional fermented soy foods like natto, miso, and tempeh are different from highly processed soy milk, soy protein isolate, soy burgers, and soy desserts. Our recommendation is to avoid conventional, GMO, highly processed, unfermented soy as a daily staple and choose organic fermented soy if you tolerate it.

Is farm-raised fish bad for you?

Some farm-raised fish may be better than others, but sourcing matters. Farmed fish can differ from wild fish in feed, fat content, omega-3 to omega-6 balance, contaminant exposure, antibiotic use, and environmental impact. When possible, choose wild-caught, low-mercury fish like salmon, sardines, and anchovies from reputable sources.

Is fruit juice healthy?

Fruit juice is not the same as whole fruit. Even 100 percent juice lacks the fiber and food structure that helps whole fruit digest more slowly and keep you full. Store-bought juice is easy to overconsume and can contribute to excess calorie and sugar intake. Choose whole fruit first, and if you juice at home, keep it vegetable-heavy and moderate.

What should I eat instead of fake health foods?

Eat real food as close to the way God made it as possible. Build your meals around vegetables, herbs, spices, whole fruit, clean protein, fermented foods, nuts, seeds, legumes if tolerated, and healthy fats. This is the foundation of Biblical health and the abundant life.
