30 Foods High In Thiamin (Vitamin B1)

Thiamin (vitamin B1) is a member of the B-vitamin group, and it is one of the essential vitamins that we need to obtain from our diet.

This important nutrient plays a crucial role in energy production and the growth, maintenance, and function of cells (1).

According to the FDA’s published daily values, the ‘daily value’ for thiamin is 1.2 mg (2).

Some of the best sources include seafood, pork, legumes, whole grains, nuts, seeds, and vegetables.

This article provides a list of foods high in thiamin alongside the amount of the nutrient they provide per serving and per 100 grams.

1) Wheat Germ

The germ of a cereal grain is responsible for reproducing and helping to grow a new plant.

In nutritional terms, the germ is also the most nutrient-dense part of wheat.

Notably, just one ounce (28 grams) of toasted wheat germ provides 39% of thiamin’s daily value (3).

2) Flax Seeds

Flax seeds are an excellent source of nutritional value, and they provide fiber, protein, essential fatty acids, and other B vitamins such as folate.

These little seeds are a great source of thiamin, too, with an ounce serving providing 39% of the daily value (4).

3) Sunflower Seeds

Sunflower seeds are another nutrient-rich seed, and they provide 35% of the daily value for thiamin per ounce serving (5).

4) Hemp Seeds

Hemp seeds have grown in popularity over recent years as their nutritional properties have become appreciated.

As well as being high in thiamin, these seeds are one of the best sources of niacin.

Per ounce serving, hemp seeds offer 30% of the daily value for thiamin (6).

5) Pine Nuts

Although somewhat lesser-known than other nuts, pine nuts are delicious – they’re one of the major ingredients in the condiment pesto.

These nuts offer good nutritional value too, and they provide 29% of the daily value for thiamin (7).

6) Pistachio Nuts

Arguably one of the tastiest nuts, pistachios are also an excellent source of nutrients.

These nutrients include thiamin, with pistachios offering 16% of the daily value per ounce serving (8).

7) Ground Pork (Cooked)

Pork offers more thiamin than other types of meat, and ground pork provides 50% of the daily value for thiamin per three-ounce (85-gram) serving (9).

As well as providing vitamin B1, ground pork is also a good source of riboflavin (B2) and niacin (B3).

8) Ham

Since it is a form of pork, ham is also an excellent source of thiamin.

Just one thick slice (63 grams) of cooked ham supplies 33% of the vitamin’s daily value (10).

9) Lean Pork Chop

Lean pork chops are another form of pork that provides a good amount of thiamin, as well as other B vitamins like B6 and B12.

A cooked large pork chop provides 64% of the vitamin’s daily value (11).

10) Wheat Bran

The wheat kernel’s outer layer is known as ‘wheat bran,’ and it is a rich source of fiber, vitamins, and minerals.

Wheat bran is high in most B vitamins, and it offers 25% of the daily value for thiamin per cup serving (12).

11) Bratwurst

Bratwurst is a type of German sausage that features pork and a variety of seasonings.

Due to its pork content, bratwurst is relatively high in thiamin, with a 75-gram sausage providing 29% of the daily value (13).

12) Rye Bread

Bread made with rye tends to be more nutrient-dense than regular bread made with white flour.

A two-slice serving provides nearly a quarter of the daily value for thiamin with 23% (14).

13) Bagel (Whole Wheat)

Just like rye bread is more nutrient-rich, so is bread from genuine whole wheat.

For instance, a regular whole wheat bagel provides 35% of thiamin’s daily value (15).

14) Rainbow Trout

Rainbow trout is full of B vitamins, particularly vitamin B12 and niacin.

It also offers a good amount of thiamin with a three-ounce (85-gram) serving of cooked trout, offering 10% of the daily value (16).

15) Salmon

Salmon is another oily fish that contains a good source of thiamin.

A three-ounce (85-gram) serving of cooked farmed Atlantic salmon offers 24% of the daily value for the vitamin (17).

Salmon is also rich in choline, a nutrient that shares some similarities with the B vitamins.

16) Mussels

Mussels are among the most nutrient-rich seafood options.

These little shellfish are high in thiamin, too, with a cup serving providing 38% of the daily value (18).

17) Chicken Liver

Chicken liver offers significant quantities of vitamin B5, B12, and all the B vitamins.
