The short answer

Build a short list around meals you actually eat: eggs, meat or fish, tolerated pasteurized dairy, whole fruit and roots such as potatoes or carrots. For packaged foods, read the ingredient list and nutrition panel together; ingredient length alone is a poor verdict. Compare two realistic options, check allergens and serving sizes, and keep convenience foods that help you eat consistently. “Simple” is a useful preference, not a purity test or proof that every additive is harmful.

Start with meals, not a blacklist

A grocery list works best when it maps to meals. Pick a few breakfasts, lunches and dinners you like, then buy components you will use: eggs; fish or meat; pasteurized dairy you tolerate; whole fruit; potatoes, carrots or sweet potatoes; and seasonings or pantry foods that make cooking practical. The aim is enough energy and protein, foods you enjoy, and variety over time—not a perfect trolley.

This reflects Optimally’s primal-inspired, micronutrient-focused direction, while leaving room for different tastes, cultures, budgets and exclusions. It is not a strict selector for Aajonus Vonderplanitz’s Primal Diet or Ray Peat’s separate writing.

A five-step package check

  • Read the product name and serving size first. A “family pack” and a single serving can make numbers look different.
  • Read ingredients from the top. In US labeling, ingredients are generally listed by descending weight; local rules may have details and exceptions.
  • Identify the practical question: added sugar, allergen, type of oil, processing marker, protein, sodium, or simply “will this work for dinner?”
  • Compare like with like. Plain yoghurt versus flavoured yoghurt is a clearer comparison than yoghurt versus a snack bar.
  • Check the package itself. A scanner record or photo can be incomplete or outdated, and an allergen warning must be verified.

Simple does not always mean better

A long list is not automatically a sign of a poor choice. A home-cooked stew can list meat, carrots, potatoes, herbs, broth and several seasonings. A short list can still describe a sweet drink or a product with little of the nutrients you hoped to find. Ingredient type, amount, food role and overall pattern all matter.

The NOVA framework classifies foods by processing and industrial formulation, but it is not a full nutrient score and its groups are broad. A product’s degree of processing can be one useful question; it does not make two products within a category nutritionally equivalent.

Three realistic trolley swaps

For breakfast, compare plain yoghurt plus berries with a sweetened dessert-style yoghurt. If you want to control sweetness, the plain tub and fruit are flexible. If the sweetened cup is what you will eat, compare its label and portion rather than skipping breakfast in pursuit of a perfect choice.

For a quick dinner, compare plain frozen fish and potatoes with a breaded fish meal. The former gives you more control over sides and seasoning; the latter may save time. Read its ingredients and sodium, then choose the convenience tradeoff consciously.

For snacks, compare a whole apple and a packaged fruit bar. The apple is a whole-fruit option; the bar may travel better. Its score should be read as an editorial summary of the available data, not a statement that the fruit bar has no place in your day.

Plan for allergies, budget and waste

Buy portions you can use, choose frozen or canned staples where they make meals affordable, and plan leftovers. When a package has a “may contain” statement or a named allergen, follow your own allergy plan; a high rating never makes it safe. If an exclusion is preference-based, Optimally can keep it in mind for suggestions, but the physical label remains authoritative.

Food quality and food safety are separate. Cook animal foods safely and choose pasteurized dairy as the default. Organic or pasture-raised marketing does not make raw meat, eggs or milk pathogen-free.

A little more clarity

Common questions

Are fewer ingredients always healthier?

No. Ingredient count alone does not show nutrient quality, portion, processing purpose or how a food fits your diet.

Can Optimally create a strict Primal or Ray Peat shopping list?

Optimally follows one primal-inspired approach and does not select between diet identities. Personal allergies, intolerances and exclusions still inform suggestions.

Can a scanner confirm a product is allergy-safe?

No. Verify the physical package and follow your personal allergy guidance; app data may be incomplete.
