Patient Resource — Quick Reference

Cancer Nutrition at a glance

Vitae Arete

A practical one-page reference for patients and caregivers navigating treatment-related nutrition. Use it during chemo cycles, in clinic visits, or pinned to the fridge. Adapted from The Cancer Treatment Nutrition Guide.

The shortest version of nutrition during treatment: Calories matter more than perfection. Protein matters more than calories. Hydration matters more than either. When eating is hard, the right strategy isn't "eat better food" — it's "eat what your body will accept, on a schedule, in small amounts." This sheet is the playbook.

Seven Practical Rules

1. Eat by the clock, not the appetite
Treatment can dull hunger signals. Set timers every 2–3 hours and eat something — even small. Waiting until you're "hungry" often means waiting too long.
2. Protein every meal, every snack
Aim for 25–35g per meal. Greek yogurt, eggs, cottage cheese, fish, tofu, protein shakes, peanut butter. Muscle preservation is the single biggest predictor of treatment tolerance.
3. Drink first. Always.
Dehydration mimics fatigue, nausea, and brain fog. Sip 6–8 oz every hour while awake. Add electrolytes (broth, sports drink, oral rehydration) on chemo days.
4. Cold over hot when food smells nauseating
Cold foods release fewer aromas. Try smoothies, yogurt parfaits, cold sandwiches, fruit, cottage cheese — when the kitchen is too much.
5. When taste changes, lean on texture and temperature
If meat tastes metallic, switch to fish, eggs, beans, or dairy. Use plastic utensils. Tart, citrus, or marinated foods often cut metal taste.
6. Soft, neutral, frequent during mucositis
Avoid acidic, spicy, crunchy, very hot. Smooth oats, scrambled eggs, mashed avocado, yogurt, smoothies, soft pasta. Cold and bland are your friends.
7. Track weight, not calories
Weigh weekly, same time of day. Losing more than 5% of body weight in a month is a flag — call your oncology team.
+ Don't fight the cravings
If the only thing you'll eat is a peanut butter sandwich for three days, eat the sandwich. Tolerance > optimization.
