Thiamin is vitamin B1. For a regular intake, familiar foods are usually more useful than a ranking of exotic superfoods. Actual portions and the overall usual diet are what matter.
Spread sources across the week
| Food group | Practical idea |
|---|---|
| Whole grains | Plan oatmeal, wholemeal bread or a whole-grain side dish |
| Legumes | Prepare beans or lentils following safe cooking instructions |
| Seeds and nuts | Use suitable small additions to meals |
| Meat and fish | Pork and certain fish species can contribute, among other foods |
The table is not a calculated daily meal plan. Levels vary with the food and its preparation. Thiamin sources are not the same as vitamin B12 sources either: several plant foods can contribute to B1 intake.
Limit cooking losses
Thiamin is water-soluble and sensitive to heat. Prolonged soaking, unnecessarily long heating and discarding cooking water can increase losses. Suitable cooking liquid can be used in soups, for example. The cooking times needed for safe preparation of legumes remain important.
When diet alone does not answer the whole question
Severe malnutrition, alcohol dependence, persistent vomiting or certain gastrointestinal diseases and operations can change the risk. These situations need targeted medical assessment and, where appropriate, treatment that cannot be determined from an ordinary food comparison.
New confusion, marked unsteadiness when walking or eye movement disturbances are urgent warning signs, particularly with these risk factors. Do not wait for a routine appointment or first experiment with a self-chosen high dose.
Frequently asked questions
Does fatigue prove a B1 deficiency?
No. Fatigue alone is non-specific and has many possible causes.
Does everyone need an extra capsule?
No. The reason, nutritional status and any medical instructions determine that.
