牛肉干是一种高蛋白,低b Snack That’s Also Great in Recipes

Fun fact: Beef jerky originated as a food preservation technique, as it allows us to store beef for long periods of time and provides a consistent supply of a nutrient-dense,protein-rich and portable food source.

The tasty snack typically made with lean cuts of beef that are sliced into strips and then dehydrated (or dried). Jerky is often prepared using a range of spices and seasonings to add extra flavor.

But it also contains a range of essential nutrients, including protein, iron, B vitamins and zinc — deeming jerky both a convenient snack and a great way to help fuel our bodies.

1.Beef Is Linked to Bolstered Brain Health

Choline is an essential nutrient that is vital for brain health and it's naturally present in some foods, including beef jerky.

Choline is critical during the first two years of life. Higher choline intake by the mother during the third trimester is linked to improved infant processing speed and has lasting beneficial effects on the child's cognitive function, according to the January 2018 issue of theFASEB Journal.

Higher choline intake is also associated with better cognitive performance and increased brain white matter hyper-intensity in older adults, according to theNational Institutes of Health(NIH)。

And people with Alzheimer's disease have been found to have lower levels of the enzyme that convertscholine into acetylcholinein the brain.

2. Beef Jerky Can Help Build and Maintain Muscle

Beef is packed with essential nutrients that can help your body reach peak performance and preserve what you're building. Clocking in with more than nine grams per ounce, beef jerky provides a hefty boost of protein in a small amount of food.

High-quality, protein-rich foods are vital to building, maintain and repairing muscle, which helps optimize the muscle training response both during exercise and afterward, inthe recovery period, according to theNIH.

Research has found that a diet rich in high-quality protein in the form of lean red meat is safe and effective for enhancing the effects of resistance training on lean tissue mass and muscle strength in older women, according to a randomized control trial published in the April 2014 issue of theAmerican Journal of Clinical Nutrition.

Enjoying lean cuts of beef in moderation may be a healthy way to increase protein intake, preserve muscle mass and improve overall diet and nutrient quality.

Also integral to muscle metabolism is iron, which helps red blood cells deliver oxygen throughout the body, according to theNIH.

Low levels of iron may lead to iron deficiency or iron deficiency anemia, with symptoms such as fatigue, weakness, gastrointestinal distress, immunity issues and impaired cognitive function.

There are two main forms of iron: non-heme, which comes from iron-fortified foods or plant-based foods and heme, which is found in animal products such as beef. One ounce of beef jerky provides 9 percent of the DV for iron, making it a good way to reach your daily dose.

3. Beef Jerky Can Be a Healthy Part of a Weight Management Plan

Feelings of satiety can have a hugely positive effect on weight management. Research has shown that high-quality protein may make you feel more satisfied after a meal, which canhelp prevent overeating.

A higher protein diet has been shown to improve satiety, appetite control and decreased subsequent food intake, according to a study published in the September 2014 issue ofNutrition Journal.

In addition, a higher protein breakfast specifically showed lasting effects on satiety throughout the day, as shown in a small study published in the February 2013 issue of theAmerican Journal of Clinical Nutrition.

Food Allergies

Although uncommon, a meat allergy may develop at any time in life, and is sometimes caused by a bite from the Lone Star tick, found predominantly in the Southeastern states, according to theAmerican College of Allergy, Asthma & Immunology.

Speak to an allergist if you suspect you have a meat allergy. Food allergies can cause severe and life-threatening symptoms, and you may need to avoid meat and carry an EpiPen with you.

What's more, beef jerky often contains many additives such as marinades and spices that may be an allergy source.

Drug Interactions

There are no indications of interactions between beef jerky and medications.

Sodium Intake

Store-bought beef jerky typically has a high amount of sodium per one-ounce serving (approximately 500 milligrams). The2015-2020 Dietary Guidelinesrecommend that sodium is capped at 2,300 milligrams per day as part of a healthy eating pattern.

Due to jerky's high salt content, moderation is important and for people who need to limit thier sodium (such as those with high blood pressure). Just 5 ounces of jerky exceeds the daily recommendation.

Tolimit your sodium intake, choose lower-sodium brands or follow our step-by-step instructions on how to make your own, below.

Beef jerky is available nationwide in a range of flavors. Keep store-bought jerky in its original container until ready to eat and homemade jerky in a resealable bag or airtight container, both at room temperature.

If unopened, beef jerky should last up to one year while properly stored opened jerky can last one to two months.

Jerky is created via dehydrating, or removing moisture so that bacteria and enzymes cannot react with the meat and cause it to spoil. Beef jerky can be made at home fairly easily, both with and without a dehydrator. Try this basic recipe for oven-baked homemade beef jerky.

A Homemade Beef Jerky Recipe

1. Thinly slice two pounds lean beef, such as eye or top round. If you place it in the freezer for 20 minutes prior to slicing, it will be easier to cut.
2. In a resealable bag, add 1 teaspoon ground black pepper, 1 teaspoon kosher salt and optional other flavorings, such as soy sauce, garlic powder or onion powder.
3. Add the sliced beef to the bag and toss until evenly coated. Refrigerate for 30 minutes or overnight.
4. Preheat oven to 175 degrees Fahrenheit. Line two large baking sheets with aluminum foil and place wire cooling racks on each.
5. Lay out the beef strips on the racks in a single layer. Bake for two hours; then turn beef pieces over and cook two more hours.
