Tamales, Pan Dulce, and Your A1C: Managing Diabetes Through the Holidays in the Rio Grande Valley
Most holiday diabetes advice was written by someone who has never been to a tamalada.
It assumes the challenge is one turkey dinner, that portions are negotiable, and that declining a plate is a neutral act. In a Valley family it is none of those things. The season runs from Thanksgiving through Día de Reyes, food arrives continuously, and turning down what your tía spent Saturday making communicates something you did not intend to say.
So this is not a list of foods to avoid. It is a practical guide to getting through six weeks of holidays with your blood sugar and your family relationships intact.
November is also Diabetes Awareness Month, which makes it a fitting time to look at where your numbers actually stand.
The Holidays Are Six Weeks Long, Not One Day
Here is the reassuring part, and it is grounded in how the test works.
Your A1C reflects average blood sugar over roughly the previous two to three months, weighted toward the most recent weeks. One Thanksgiving plate does not move it meaningfully. A single high reading after Christmas dinner is not a failure and is not a reason to give up on the whole season.
What does move it is the pattern, six weeks of larger portions, more sweets in the house, less walking because the days are short and busy, and a routine that slips. The risk of the holidays is not any one meal. It is the drift.
That reframing matters, because the all-or-nothing response is what causes real damage. Someone eats two tamales, decides the season is lost, and stops checking their sugar until January. The plate was not the problem. The three weeks that followed it were.
What Actually Happens at a Holiday Meal
Three things drive the blood sugar rise, and knowing which is which tells you where to intervene.
The carbohydrate load. Holiday meals stack carbohydrates that arrive together: tamales, rice, beans, tortillas, and dessert on one plate. Any single one may be manageable; the total is what produces the spike.
The timing. Eating is spread across the whole day, so blood sugar never fully returns to baseline before the next round arrives.
The alcohol. Alcohol has its own effect, discussed below, and it is the one most people get wrong.
Fat and protein also slow digestion, which can delay the rise for hours, one reason a reading at bedtime after a heavy meal sometimes surprises people more than the reading right after it.
The Valley Holiday Table, Food by Food
These are approximate values. Preparation varies enormously, every family's tamales are different, and a bakery concha is not the same size as your neighbor's. Use these as a rough map, not a rulebook.
| Food | Approximate carbohydrates | Practical approach |
|---|---|---|
| Tamal (pork or chicken, one) | About 15 to 30 g, depending on size | Two tamales and a salad is a reasonable plate. Two tamales, rice, beans, and tortillas is three meals' worth of carbohydrate at once. |
| Tamal de dulce (one) | Higher, masa plus added sugar | Treat it as dessert, not as another tamal. |
| Concha or other pan dulce (one) | About 30 to 50 g | A concha with coffee is a dessert eaten at breakfast. Pair it with eggs rather than eating it alone. |
| Buñuelo (one) | About 15 to 25 g | Smaller than it looks. One is genuinely fine for most people. |
| Champurrado (one cup) | Roughly 30 to 45 g | Masa plus piloncillo plus milk. This is a dessert in a mug, count it as one, or ask for a smaller cup. |
| Ponche (one cup) | Roughly 25 to 35 g, more if sweetened heavily | The fruit is fine; the piloncillo is what counts. Ask for more fruit and less liquid. |
| Flour tortilla (one medium) | About 25 g; large ones considerably more | Corn tortillas are smaller and higher in fiber. An easy substitution that costs nothing socially. |
| Spanish rice (half cup) | About 20 to 25 g | The easiest thing on the plate to halve without anyone noticing. |
| Frijoles (half cup) | About 15 to 20 g, with useful fiber | Among the better choices on the table. Fiber and protein slow the rise. |
Nothing here is forbidden. The question is never whether you can have a tamal. It is how many things sharing that plate are also carbohydrates.
Strategies That Work Better Than Avoidance
Eat before you go. Arriving hungry to a table of holiday food is the reliable path to a plate you did not intend. A small protein-based snack beforehand changes what happens next.
Fill the plate in order. Vegetables and protein first, carbohydrates last, on the same plate. It is a portion strategy that requires no announcement and no explanation.
Take the walk. A 10 to 15 minute walk after a large meal measurably lowers the glucose rise, because working muscle pulls glucose from the blood without needing much insulin. In a Valley December the weather is on your side. Invite someone, it reads as sobremesa, not as medical management.
Drink water between everything else. Especially at gatherings where a glass in your hand is expected.
Choose your indulgence deliberately. Decide beforehand whether tonight's is the tamales, the buñuelos, or the champurrado. Picking one is sustainable across six weeks. Having all three at every gathering is not.
Keep your normal meals normal. Skipping lunch to bank carbohydrates for dinner backfires: it drives you into the evening hungry and, if you take insulin or a sulfonylurea, risks a low before the meal even starts.
Protect your sleep and your routine. Short sleep raises insulin resistance the next day. Late nights are part of the season, but a run of them shows up in your morning numbers.
Alcohol: The Part Most People Get Wrong
Most people assume alcohol raises blood sugar. Frequently it does the opposite, and that is the more dangerous direction.
While your liver is processing alcohol, it does less of its usual job releasing stored glucose. If you take insulin or a sulfonylurea, that raises the risk of hypoglycemia, and the drop can arrive hours later, often overnight, while you are asleep.
Practical rules: never drink on an empty stomach, eat something containing carbohydrate alongside, check before bed after a night with alcohol, and know that the symptoms of a low and the effects of drinking look similar enough that people around you may not recognize what is happening. Mixers matter too, regular soda, juice, and sweetened ponche carry their own carbohydrate load.
Do Not Skip Your Medication to Make Room
This one is worth stating plainly, because it is the most common holiday mistake we see.
Skipping metformin or insulin to "make room" for a big meal reverses what your body needs at exactly the wrong moment: more carbohydrate arriving with less medication working. If you take mealtime insulin and adjust to carbohydrate counts, a heavier meal usually means more insulin, not less, but that decision belongs to you and your physician, not to a blog post.
If you genuinely expect a meal outside your usual pattern, call the office beforehand and ask. That is a two-minute conversation that prevents a bad evening.
When to Check, and What Should Prompt a Call
Check more often than usual during weeks with several gatherings, before meals, two hours after the large ones, and at bedtime after any evening involving alcohol.
Call your physician's office if you see blood sugars persistently above 250 mg/dL over a couple of days, any reading below 70 mg/dL, symptoms of a low such as shaking, sweating, confusion, or unusual weakness, or if illness has you eating and drinking far less than normal while still taking your usual medication.
Go to the emergency room for confusion, persistent vomiting, difficulty breathing, or a reading your meter will not resolve while you feel genuinely unwell.
Diabetes Awareness Month: What to Ask at Your Next Visit
November is a good moment to check that your diabetes care is complete, not just your blood sugar. The full picture includes:
- A1C, how often depends on control, typically every three to six months
- Kidney screening, a urine albumin-to-creatinine ratio and an eGFR, recommended annually
- Eye exam, a dilated retinal exam annually
- Foot exam, at least annually, and more often with any neuropathy
- Blood pressure and cholesterol, both drive the cardiovascular risk that accompanies diabetes
- Vaccines, flu, pneumococcal, and others that matter more with diabetes
If you cannot remember the last time you had the kidney or eye screening, that is the thing to schedule.
One practical note on timing: most insurance deductibles reset January 1. If you have already met yours this year, labs and diagnostic testing completed in December cost you less than identical care in January. It is a small thing that adds up, and December appointments fill quickly.

Frequently Asked Questions
Q: Can I eat tamales at all if I have diabetes?
A: Yes. A tamal is roughly 15 to 30 grams of carbohydrate depending on size, which fits within most meal plans. What causes trouble is the company it keeps, two tamales alongside rice, beans, and tortillas is a very large carbohydrate load in one sitting. Have the tamales and go lighter on everything else sharing the plate.
Q: How many carbohydrates are in one tamal?
A: Roughly 15 to 30 grams for a typical pork or chicken tamal, varying with size and how much masa is used. Homemade tamales are often larger than commercial ones. Sweet tamales run higher because of added sugar.
Q: Does one big meal ruin my A1C?
A: No. A1C reflects average blood sugar over about two to three months, so a single meal barely registers. What matters is whether one meal becomes six weeks of drift. Return to your normal routine the next day rather than writing off the season.
Q: What can I drink at a holiday party?
A: Water, unsweetened iced tea, coffee, or sparkling water with lime are all straightforward. If you drink alcohol, do it with food and be aware that it can cause a low blood sugar hours later, particularly with insulin or a sulfonylurea. Watch the mixers, regular soda and juice add carbohydrate quickly.
Q: Should I skip a meal to save up for a big dinner?
A: No. Skipping meals tends to produce overeating later, and if you take insulin or a sulfonylurea it risks hypoglycemia before dinner even arrives. Eat normally during the day and manage the portion at the gathering instead.
Q: My blood sugar has been higher all week. What should I do?
A: Return to your usual eating pattern, keep taking your medication as prescribed, add a short walk after meals, and check more often. If readings stay above 250 mg/dL for more than a couple of days, call the office. Do not adjust insulin doses on your own without guidance.
Q: Is it worth coming in before the end of the year?
A: Often, yes, for two reasons. Clinically, the end of the year is a natural point to check A1C, kidney function, and blood pressure and to catch anything overdue. Financially, if you have already met your deductible, care completed before January 1 typically costs less than the same care afterward.
Q: ¿Ofrecen orientación sobre diabetes en español?
A: Sí. Giraldo Internal Medicine is a fully bilingual practice, and diabetes education, medication instructions, and nutrition guidance are all available in Spanish. Advice about food only works when it is given in the language your family cooks in.
