You do not need a large family to shop at Costco. I live alone, shop there once or twice a month, and very little goes to waste. The secret is not eating Costco-sized portions. It is buying flexible foods, using the most fragile ingredients first, preparing foods in batches, and freezing what I will not use quickly.
I recently shared a two-part Costco run showing foods I actually purchased and use. These are not random “healthy” products that looked good on a shelf. Most of them fit into recipes, quick meals, snacks, and the bulk-cooking system I already use.

The Real Strategy: Make the Next Healthy Decision Easier
A grocery haul is only valuable when the food becomes meals. A refrigerator full of good intentions will not protect your energy during a demanding week. Your environment needs to make the next decision easier when you are hungry, tired, busy, or tempted to order whatever arrives fastest.
That is why I look for foods that can play more than one role. Frozen vegetables can be a side dish, an omelet filling, a soup ingredient, or part of a stir-fry. Chickpeas can become hummus, a salad topping, a roasted snack, or part of a bowl. More realistic uses usually mean less waste and fewer last-minute food decisions.
My Two Questions Before Buying Food in Bulk
Before a large package enters my cart, I ask two practical questions:
- Can I name at least three realistic ways I will use this food?
- Can I freeze all or part of it before it spoils?
A low unit price does not make something a bargain when half of it becomes a biology experiment in the refrigerator. Bulk buying works when the food fits your real life, not your fantasy meal-prep personality.
Fresh and Frozen Plants: The Foods I Use First
Higher fruit and vegetable intake is consistently associated with lower cardiovascular and all-cause mortality in large observational studies. That does not mean one vegetable guarantees longevity. It means that a repeatable pattern rich in fruits, vegetables, legumes, nuts, and fiber is connected with better long-term outcomes. [1]
Microgreens and Arugula: Easy Ways to Increase Plant Variety
Microgreens are one of my easiest upgrades because I can add them to eggs, bowls, salads, soups, proteins, wraps, and homemade pizza. Research has found that nutrient concentrations vary widely by microgreen variety, with several varieties providing concentrated vitamins and carotenoids. [6] They do not replace full servings of vegetables, but they make it easier to add color, texture, and plant diversity to food you were already going to eat.
Once the package is open, microgreens can go bad quickly. I move them to the front of the refrigerator and use generous handfuls instead of treating them as a decorative garnish. Arugula is another flexible green. Its peppery flavor works under eggs, chicken, fish, tofu, [gluten-free] pasta, or warm vegetables, which wilt it slightly and make a larger serving easy to eat.
Arugula is also much lower in oxalates than spinach. That does not make spinach a “bad” food, but it is one reason I encourage people to rotate their greens instead of using large amounts of the same one every day, especially in smoothies and salads. Quantity, frequency, food variety, and the individual’s health history all matter.
Frozen Vegetables: Nutrition Insurance for Busy Weeks
Frozen vegetables do not wilt during back-to-back meetings. They wait patiently, which is more than I can say for some fresh produce. Studies comparing fresh and frozen fruits and vegetables have found that nutrient retention is often comparable, although results vary by food, nutrient, storage time, and processing method. [7]
I steam several servings of the Normandy vegetable blend and use it with eggs, chicken, fish, lean meat, tofu, beans, or edamame pasta. Broccoli and cauliflower are cruciferous vegetables, and higher intakes of cruciferous and leafy vegetables have been associated with lower cardiovascular and all-cause mortality in prospective research. [1]
By the way, a great way to use a bunch of fresh broccoli, especially if it’s about to go bad, is to turn into pizza dough. See my Mini Broccoli Crust Pizzas recipe. Artichoke hearts, olives, tomatoes, and a protein topping can turn them into a more complete meal.
SunGold Kiwi and Apples: Portable Foods With Different Priorities
The edible skin of SunGold kiwis boosts content of vitamin C, fiber, vitamin E, and folate (B9), isn’t it a beautiful thing? I often eat it after washing the fruit well, best is to soak it in water with soaking soda for 12-15 minutes. Apples are another staple because they travel well, last longer than many fruits, and pair easily with protein or fat when I need a more substantial snack.
The organic decision can differ between these two fruits. In EWG’s 2026 Shopper’s Guide, apples appear on the Dirty Dozen list, while kiwi appears on the Clean Fifteen list. [12] I use the guide to prioritize where buying organic matters most to me, rather than assuming everything in my cart must be organic.
Dried Figs: Nutritious, Concentrated, and Still Worth Portioning
Dried figs provide fiber and plant compounds, but removing water concentrates the carbohydrate and natural sugar. I enjoy them, but I do not treat the word “natural” as permission to ignore portions or context.
Unless I am about to train, I generally avoid eating dried fruit, sweeter tropical fruit, potatoes, tubers, and other higher-carbohydrate foods by themselves. I prefer to combine them with protein, healthy fat, and fiber, or eat them as dessert as part of a balanced meal. One or two figs after a protein-forward meal is very different from grazing through the bag while distracted.
How I Think About Carbohydrate Timing
Carbohydrates are not automatically good or bad. The amount, type, timing, activity level, metabolic health, and the rest of the meal all matter. Every case is different, which is why rigid social-media rules often create more confusion than clarity.
Morning May Be a Better Window for More Complex Carbohydrates
Human studies show that glucose tolerance and insulin sensitivity are generally better earlier in the day than in the evening. [10] That does not mean everyone needs a large carbohydrate-heavy breakfast. It means that when someone includes a larger portion of whole-food carbohydrates, earlier in the day may be a more favorable window than late at night, depending on the person’s schedule, sleep, training, medications, and glucose response.
A Small Amount of Carbohydrate Can Support Training
On demanding lifting days, 20-30g of carbs before training can support energy and training output, especially when the session is long, high-volume, or performed after several hours without food. After a substantial workout, combining protein with carbohydrate within the next couple of hours can support recovery, muscle glycogen restoration, and the overall training adaptation. [11]
This is not permission to turn every short workout into a sports-drink event. Total daily nutrition, protein intake, overall carbohydrate needs, and training demands matter more than chasing a perfect five-minute “anabolic window.”
People with diabetes, prediabetes, reactive hypoglycemia, insulin resistance, or glucose-lowering medications may need a different strategy. Carbohydrate timing should be personalized with appropriate clinical guidance when medication safety is involved.
Plant Protein and Fiber Staples
Protein gets plenty of attention, but fiber deserves a seat at the same table. Higher dietary fiber intake is associated with lower all-cause, cardiovascular, and cancer mortality in dose-response research. [4] Several foods in this haul provide both plant protein and fiber.
Beans and Chickpeas: Affordable, Flexible, and Underrated
Beans and chickpeas can become salads, bowls, soups, chili, pasta additions, roasted snacks, or homemade hummus. They provide plant protein, fiber, resistant starch, minerals, and plant compounds. Higher legume consumption has been associated with lower all-cause and stroke mortality, although this is an association across eating patterns, not proof that one can of beans prevents disease. [2]
For a simple dip idea, try my Avocado-Hummus Dip. You can also rinse chickpeas and add them to salads or roast them with herbs and spices.
Tofu and Edamame Pasta: Plant Protein With an Organic Priority
Tofu and edamame pasta give me additional plant-protein options. Higher plant-protein intake, particularly when it replaces some processed or non-lean red meat, has been associated with modest reductions in overall and cardiovascular mortality. [3]
With soy and its by-products, I have a specific buying standard: I recommend choosing certified organic products whenever possible. Soybeans are one of the most widely genetically engineered (GMO) crops. USDA reported that 96% of U.S. soybean acreage used herbicide-tolerant varieties in 2025. [15] USDA organic standards prohibit the intentional use of genetically engineered seeds and ingredients. [16]
Organic does not mean pesticide-free, but it does provide a regulated production standard and avoids the intentional use of GMOs. For tofu, tempeh, edamame, and soy milk, organic is my preference and recommendation.
Flavor Builders: The Foods That Prevent “Healthy” From Becoming Boring
People often think they dislike healthy eating when the real problem is that their meals are dry, repetitive, and painfully boring. Nobody sustains a lifestyle built around sad chicken and lonely broccoli.
Hearts of Palm
I grew up eating hearts of palm in Brazil. They have a mild flavor and satisfying texture, and they are easy to chop into salads, bowls, egg dishes, and cold vegetable plates. Because jarred and canned products can contain significant sodium, check the label and rinse when appropriate.
Artichoke Hearts
Artichoke hearts add flavor, texture, fiber, and plant variety. When they are marinated in oil, I count that oil as part of the meal’s fat. I do not automatically add another large pour of dressing because “healthy fat” still contributes energy. The marinade can be mixed with lemon, vinegar, mustard, or herbs to make a quick dressing.
I use artichokes in salads, omelets, pasta, vegetables, homemade pizza, and even a turkey-crust pizza. Their job is not only nutrition. They make the meal taste good enough that I want to eat it again.
Tomato-Basil Sauce
Processing is not automatically bad. Tomato sauce is a useful example because cooking and processing tomatoes can improve the bioavailability of lycopene, a carotenoid found in tomatoes. [9] I still check the ingredient list for added sugar, sodium, and the type of oil, but a simple tomato sauce can make tofu, beans, vegetables, eggs, edamame pasta, or homemade pizza much easier to execute.
Convenience Foods Are Backup, Not the Foundation
I keep protein bars, protein powders, and ready-to-drink shakes available because real life happens. They can help during travel, errands, long workdays, pre-workout situations, or periods when someone is working toward a higher protein target and needs help filling a gap.
But I do not recommend making them the daily foundation of nutrition. Many bars are high in total carbohydrate, include multiple gums and additives, and are heavily processed. Protein powders and shakes are processed too. Plant-based isolates often require substantial processing to concentrate the protein, while whey-based products can create problems for people who do not tolerate dairy proteins well. The right choice depends on the person, not a marketing claim on the front of the package.
I often give clients a short list of products that meet the standards we are targeting. Even then, these products are resources, backups, or gap-fillers. They do not replace the value of meals built from whole and minimally processed foods.
What I Check on a Protein Bar or Shake
- Protein amount and source
- Total carbohydrate, fiber, added sugar, and sweeteners
- Calories relative to how I plan to use it
- Gums, sugar alcohols, and additives that may affect digestion
- Dairy, soy, or other ingredients that may not fit the person’s tolerance
- Whether it is being used intentionally or simply because it is convenient
Sometimes I eat half a bar. Sometimes I eat the whole bar as part of a meal or around training. I do not pretend the calories disappear because the wrapper says “protein.”
Almond Butter: Nutritious and Extremely Easy to Overeat
Nut consumption is associated with lower total mortality in large prospective cohorts. [5] Almond and other nut butters can be a useful source of healthy fat and minerals, but it is energy-dense. A measured serving with an apple, chia bowl, smoothie, or meal is different from repeatedly visiting the jar with a spoon. I know. The spoon can be very persuasive, at least it is for me.
How I Prioritize Organic Foods Without Demanding Perfection
I do not believe every food must be purchased organic. I use the Environmental Working Group’s annual Shopper’s Guide, including the Dirty Dozen and Clean Fifteen, to decide where I want to prioritize my budget. The Dirty Dozen identifies produce with the highest pesticide-residue scores in EWG’s analysis of USDA data, while the Clean Fifteen identifies foods with lower residue scores. [12]
When a food is high on the Dirty Dozen list, I prefer to buy organic as much as possible. When it is on the Clean Fifteen list, I am generally more comfortable buying conventional. Availability, budget, how frequently I eat the food, and whether I eat the peel also influence the decision.
My Produce-Washing Approach
FDA’s standard recommendation is to rinse produce thoroughly under running water, rub or brush firm produce, and avoid soap, detergent, bleach, or commercial produce washes. [14]
For some firm conventional fruits and vegetables, I may also use a baking-soda soak: about 1 teaspoon of baking soda in 2 cups of water for approximately 12 to 15 minutes, followed by a thorough rinse under running water. A study in apples found that a baking-soda solution removed certain surface pesticide residues more effectively than tap water or bleach solution. [13]
That study does not prove that baking soda removes every pesticide, herbicide, or chemical from every food. It cannot reliably remove residues that have penetrated the peel or plant tissue, and it is not a substitute for good food-safety practices. I use it as one practical exposure-reduction step, not a magic detox bath.
The goal is not fear
Do not stop eating fruits and vegetables because organic is unavailable or outside your budget. A practical plan that increases plant intake and reduces avoidable exposure is more useful than perfection that leads to eating fewer plants.
A Simple Meal-Building Formula From a Costco Haul
A useful grocery haul gives you components, not another complicated recipe assignment. My basic formula is:
| 1 Protein | 1 to 2 Plants | 1 Flavor Builder | Optional Performance Carb |
| Eggs, chicken, fish, lean meat, tofu, beans, or edamame pasta | Frozen vegetables, mixed greens, arugula, tomatoes, microgreens, apples, kiwi | Tomato sauce, artichokes, hearts of palm, herbs, lemon, nuts and seeds | Beans, fruit, root vegetables, or another whole-food carbohydrate based on goals and timing |
Five Fast Meals Using These Foods
Tofu and vegetable skillet: Air-fry or sauté organic tofu. Add steamed Normandy vegetables and tomato-basil sauce. Finish with microgreens.
Edamame pasta with artichokes: Combine edamame pasta, tomato sauce, artichoke hearts, broccoli, and arugula. Adjust the serving and add another protein when your needs require it.
Chickpea and hearts-of-palm salad: Mix rinsed chickpeas, chopped hearts of palm, arugula, microgreens, tomatoes, lemon, herbs, and a small amount of artichoke marinade.
Vegetable omelet: Add steamed vegetables and chopped artichokes to eggs and egg whites. Finish with arugula or microgreens.
Training-day snack or recovery plate: Use a small portion of fruit or dried figs before a demanding session when appropriate. After training, combine protein with a whole-food carbohydrate based on your goals and tolerance.
How I Prevent Food Waste When Shopping in Bulk
Use fragile foods first. Microgreens and arugula move to the front of the refrigerator and into the first meals of the week.
Prepare components, not identical meals. I may steam several servings of vegetables, but I use them with different proteins, sauces, and meals.
Freeze early. I freeze portions while they are still fresh, not after they have spent a week negotiating with me from the back of the refrigerator.
Choose ingredients with multiple uses. The more meals an ingredient can support, the less likely it is to be wasted.
Label and date frozen portions. A mystery container is not a meal plan. A date and a simple label make the food more likely to be used.
When “Healthy Food” Still Does Not Feel Healthy for You
Two people can eat the same food and have very different experiences. A bean-heavy meal may feel fantastic for one person and create significant bloating for another. A protein powder may be convenient for one client and aggravate symptoms for someone who reacts to dairy proteins, sweeteners, gums, or another ingredient.
My role is not to hand everyone the same menu. I guide clients in organizing nutrition and lifestyle strategies around their goals, preferences, symptoms, schedule, training, and available data. When appropriate, food-sensitivity testing, microbiome testing, bloodwork, or glucose tracking may give us additional context. These tools do not replace good judgment, but they can help us stop guessing.

Your Action Steps
You do not need to recreate my entire Costco cart. Start with a small system you can actually use this week:
- Choose one fresh green you will use within several days, then rotate to another green the next time you shop.
- Choose one frozen vegetable for diversity and more fiber and micronutrients.
- Choose one protein and fiber staple, such as beans, chickpeas, organic tofu, or edamame pasta.
- Choose one flavor builder, such as artichokes, hearts of palm, or tomato sauce.
- Choose one healthy fat for additional flavor and complement the diet such as chia, hemp, and pumpkin seeds, and nuts like walnuts and cashews.
- Choose one intentional convenience food for demanding days.
- Before buying in bulk, ask: Can I use it three ways, and can I freeze it?
Progress does not require a perfect refrigerator. It requires foods you enjoy, a plan you can execute, and enough flexibility to keep going when the week gets messy.
Frequently Asked Questions
Are dried figs too high in sugar?
Dried figs are a concentrated source of natural carbohydrate because much of the water has been removed. They also provide fiber and plant compounds. I generally keep the portion small and prefer eating them after a protein-forward meal or around training rather than grazing on them by themselves. Individual glucose response and goals matter.
Is tofu healthy, and why do you recommend organic soy?
Tofu can be a useful source of plant protein. I recommend certified organic tofu and other soy foods because most U.S. soybean acreage uses genetically engineered, herbicide-tolerant varieties. USDA organic standards prohibit the intentional use of GMO seeds and ingredients. Organic does not mean pesticide-free, but it is the standard I prefer for soy and its by-products.
Are frozen vegetables as nutritious as fresh vegetables?
They can be nutritionally comparable. Nutrient retention varies by food, nutrient, processing method, and storage time. Frozen vegetables are valuable because they reduce waste and make consistent vegetable intake easier.
Should I eat fruit, potatoes, or other carbohydrate-rich foods by themselves?
There is no universal rule, but I generally prefer pairing higher-sugar fruit, dried fruit, potatoes, tubers, and other higher-carbohydrate foods with protein, fat, and fiber unless I am intentionally using a small amount around training. The best choice depends on your activity, metabolic health, goals, and individual response.
Are protein bars and protein shakes healthy?
I recommend using them as backups. They are processed foods and ingredient quality varies widely. Check the protein source, carbohydrates, sweeteners, gums, additives, calories, and your digestive response. I use them to fill a gap, not as the daily foundation of nutrition.
Do I need to buy everything organic?
No. I use EWG’s Dirty Dozen and Clean Fifteen as a practical guide. I prioritize organic versions of foods with higher residue scores when possible, especially foods I eat frequently or with the peel. Conventional produce still has value, and eating fewer fruits and vegetables because organic is unavailable is not the goal.
