Flax is a versatile plant that is used to make a range of products, from soap and paper to medicine and dye. Many different parts of the flax plant can be used in the production of consumer goods, and the seeds are prized as a rich source of nutrition. Flaxseed can be good for men, although you may not find it to be ideal based on your personal nutritional needs.

Rich in Fiber

Flaxseed is rich in fiber, as each 1 tbsp. serving provides 2.8 g of dietary fiber. Dietary fiber is important for everyone, as it promotes digestive health and provides feelings of satiety. However, consuming fiber can be more of a priority for men, as the National Academy of Sciences recommends that men consume more fiber than women. For men 50 and under, 38 grams daily is the recommended intake, and if you're over 50 and male, aim for 30 grams daily.


Flaxseed is calorie-dense, which is beneficial for men, who typically have higher calorie needs than women. Each 1 tbsp. serving of flaxseed provides 55 calories, which makes it more calorie-dense than many other types of foods, even sugar, which contains 35 calories per 1 tbsp. serving. It's calorie-dense properties come largely from its fat content -- fat contains more than twice the calories per gram than carbohydrates or protein. Flaxseed fats include omega-3 fatty aids, a type of fatty acid that promotes cardiovascular health.

Rich in Magnesium

Flaxseed is rich in magnesium, a mineral that is vital for your health because it helps regulate muscle and nerve function as well as the strength of your bones and immune system. Additionally, research from the April 2011 issue of the journal "Biological Trace Element Research" found that increased magnesium intake promoted increased levels of testosterone, the primary male hormone.

Rich in Calcium

Flaxseed is rich in calcium, a mineral that promotes bone strength, and that may also have specific benefits for men. A study published in the December 2008 issue of "Biological Trace Element Research" found that calcium could help promote increased testosterone levels.
