Eating S.O.U.L. Food: Why I Teach Families to Choose Seasonal, Organic, Unprocessed & Local

S is for SEASONAL

When food is in season, it is fresher, tastes better, and delivers the most nutrient density — and rotating with the seasons builds natural variety into your child’s diet. Out-of-season produce is typically picked unripe, shipped long distances in gas-controlled transport, and ripened in a box; that costs the environment and costs your family nutrients.

A quick season-by-season guide:

Spring: asparagus, apricots, avocados, cabbage, garlic, kale, kiwi, lettuce, mushrooms, onions, peas, pineapple, radishes, rhubarb, spinach, strawberries, Swiss chard, turnips.

Summer: apricots, avocados, beets, bell peppers, berries, cherries, corn, cucumbers, eggplant, garlic, green beans, mango, melons, peaches, plums, summer squash, tomatoes, watermelon, zucchini.

Fall: beets, bell peppers, broccoli, Brussels sprouts, cauliflower, cranberries, garlic, ginger, grapes, green beans, kiwi, leafy greens, mangoes, mushrooms, onions, parsnips, pears, peas, pineapple, potatoes, radishes, raspberries, winter squash.

Winter: avocados, beets, Brussels sprouts, cabbage, collard greens, grapefruit, kale, kiwi, leeks, onions, oranges, parsnips, pears, pineapples, potatoes, pumpkin, rutabaga, sweet potatoes, Swiss chard, turnips, winter squash.

Apples, bananas, carrots, celery, lemons, and limes are available year-round — as are frozen, canned, and dried fruits and vegetables (frozen is picked at peak ripeness and is a wonderful budget option). For a guide tuned to your state, try the Seasonal Food Guide or Eat the Seasons.

O is for ORGANIC

With the volume of pesticides and herbicides used on conventional crops, buying organic when possible matters — pesticides pollute soil and water, harm pollinators, and several are linked to serious health concerns. This is especially true for children: three long-term U. S. birth cohort studies have associated prenatal pesticide exposure — measured in mothers’ urine during pregnancy — with lower IQ, neurobehavioral problems, and ADHD in their children, and higher prenatal organophosphate exposure has been linked to differences in children’s brain structure. For pregnant and breastfeeding mothers and young children, organic is a reasonable precaution, not a luxury.

But nobody’s budget buys everything organic — so spend where it counts. The Environmental Working Group tests produce every year and publishes exactly where pesticide residues concentrate:

EWG’s Dirty Dozen for 2026 (buy these organic): spinach; kale, collard and mustard greens; strawberries; grapes; nectarines; blackberries; potatoes; pears; apples; cherries; peaches; blueberries. This year, 96% of Dirty Dozen samples tested positive for pesticides, most carrying four or more different ones. See the current Dirty Dozen list.

EWG’s Clean Fifteen for 2026 (conventional is okay): pineapples, sweet corn, avocados, papaya, onions, frozen sweet peas, asparagus, cabbage, cauliflower, watermelon, mangoes, bananas, carrots, mushrooms, kiwi. See the current Clean Fifteen list.

Notice the pattern: thin-skinned produce you eat whole (berries, greens, stone fruit) lands on the Dirty Dozen; thick-peeled produce lands on the Clean Fifteen.

On GMOs: genetically engineered ingredients hide mostly in processed foods — corn syrup and corn oil especially — though GMO zucchini, yellow squash, sweet corn, papaya, and some apples appear in U. S. markets. Since 2022, U. S. law requires GMO foods to be labeled, but the term used — “bioengineered” — confuses most shoppers. The simpler path: certified organic and Non-GMO Project Verified products are reliably GMO-free.

U is for UNPROCESSED

Eating unprocessed means eating food in its natural state, with its full complement of nutrients: a piece of fruit rather than a fruit roll-up, brown rice instead of white, whole corn instead of corn syrup. The industrialization of our food has run in parallel with an epidemic of chronic illness in our children — and the way back is real food, not labels boasting great flavor over a mishmash of chemical additives.

L is for LOCAL

Most supermarket food is produced far away by a handful of large companies. Local farmers harvest closer to ripeness, which means flavor and nutrients at their peak — no picking green, no ripening in a box, no wax or irradiation to survive the journey. Buying local supports your local economy and shrinks your food’s carbon footprint, and farmers’ markets are one of the best free field trips a child can take: kids who meet the person who grew their carrots eat more carrots.

Organic vs. Local vs. Seasonal vs. Sustainable — What’s the Difference?

These words get used interchangeably, but they’re not the same, and knowing the difference makes you a sharper shopper:

• Organic means grown without artificial pesticides, fertilizers, GMOs, irradiation, or sewage sludge — and animals raised without hormones or antibiotics — under specific USDA rules. But organic doesn’t mean local: your organic tomatoes may have flown in from another continent, with a bigger carbon footprint and no guarantee about labor or livestock conditions.
• Local means grown within some radius — which has no standard definition, so ask. A few miles? A few hundred?
• Seasonal means eaten when naturally ripe, not preserved or shipped from where it grew.
• Sustainable means the farm replenishes what growing takes out — rotating crops so the soil isn’t depleted, and minimizing spraying that would jeopardize the land.

The best way to know your food is nutritious, eco-friendly, and safely grown? Know your farmer. And if you can’t visit the farm yourself, joining a CSA or co-op is the next best thing. A label is a starting point, not the whole story.
