Do You Need To Eat Meat To Get Protein In Your Diet

In short, no, you dont need to eat meat to get enough protein into your diet. According to the latest Dietary Guidelines for Americans , its better to vary your protein sources where you can. So even if you do already eat meat, you should try and get more protein from other sources in a varied and balanced diet.

As well as meat and poultry, protein is found in all sorts of foods, such as:

  • Soy products, such as tofu and tempeh
  • Beans, lentils, and peas
  • Seafood, such as fish and shellfish
  • Whole grains and vegetables

According to the U.S. Food & Drug Administration, most Americans get enough protein in their diet to meet their needs. However, often these sources are highly processed and high in sugar, salt and saturated fats – examples including burgers or tacos.

Varying your diet to include more whole food sources of protein can help to meet your needs, as well as raising dietary fiber and lowering cholesterol. This will help to reduce your risk of heart disease and stroke, and support weight loss too.

Does Being Cold Give You A Weak Immune System

Almost every mother has said it: “Wear a jacket or you’ll catch a cold!” Is she right? Probably not, exposure to moderate cold temperatures doesn’t increase your susceptibility to infection. There are two reasons why winter is “cold and flu season.” In the winter, people spend more time indoors, in closer contact with other people who can pass on their germs. Also the influenza virus stays airborne longer when air is cold and less humid.

But researchers remain interested in this question in different populations. Some experiments with mice suggest that cold exposure might reduce the ability to cope with infection. But what about humans? Scientists have performed experiments in which volunteers were briefly dunked in cold water or spent short periods of time naked in subfreezing temperatures. They’ve studied people who lived in Antarctica and those on expeditions in the Canadian Rockies. The results have been mixed. For example, researchers documented an increase in upper respiratory infections in competitive cross-country skiers who exercise vigorously in the cold, but whether these infections are due to the cold or other factors such as the intense exercise or the dryness of the air is not known.

Is Zinc Good For Immunity

Zinc is a nutrient which is found in cells throughout the body. It helps to support the normal functioning of the immune system, as well as supporting the production of proteins and DNA.

Holland & Barrett High Strength Zinc Tablets is a high strength, daily zinc supplement, which is a great way to boost the overall levels of zinc in your body.

The Science Behind Vitamin C And Immunity

Research shows that a high vitamin C intake is associated with decreased risk of common chronic diseases, including cardiovascular disease, cancer and certain neurological conditions. When it comes to fighting off infections, vitamin C’s immune-boosting powers are likely linked to its antioxidant properties. That is, vitamin C helps regenerate other antioxidantslike vitamin Ein the body, thereby decreasing the number of harmful free radicals that can bolster infections.

So, if you can’t help your immune system by taking an over-the-counter potion or pill, what can you do to cut down on illness this winter? Differences between people who rarely get sick and those who are sick all the time may have more to do with habits than immune function, says Starnbach. Here are some tips that might help.

Clean your hands. While some germs are airborne, more often than not, illness occurs after you touch a contaminated surface, says Starnbach. Most often germs move from your hands into your eyes, nose, or mouth, so also make an effort not to touch your face.

Keep your body in top shape. Maintaining a healthy and balanced diet, exercising regularly, and getting enough sleep can help keep your body and your immune system working well.

Manage stress. Research has shown that high stress levels may impair the immune system. So whenever possible, try to be aware of your stress levels and work to lower them when they get too high.

Get vaccinated. Getting vaccinated against the flu and other diseases stimulates the immune system to protect against illness. Vaccines teach the immune system to recognize specific pathogens and prepare them to mount a defense if they are encountered.

The bottom line is that aside from vaccines, there’s really nothing you can take to improve your immune system, so it’s probably best to avoid pills and potions that make those types of claims.

Ways To Boost Your Immune System

The human immune system is a complex network of specialized cells, organs, and metabolic processes that protect our bodies from disease and help us heal when we get sick. Researchers are still working to fully understand how immunity works and what lifestyle and genetic factors are responsible for keeping this crucial system working or allowing it to break down.

Nonetheless, clinical trials and research reveal some of the most critical considerations for boosting the immune response and achieving optimum health. Here are five of the most vital steps you can take to keep your immune system in optimum health.

Proper nutrition is essential for a healthy immune system.

1. Eat Foods Containing Nutrients Essential for the Immune System

Like all parts of our bodies, a healthy immune system requires an adequate intake of specific nutrients through diet or supplementation. These essential immune system nutrients include:

  • Vitamins A, B6, folic acid, C, D, and E
  • Minerals including zinc, copper, selenium, and iron

Vitamins C is abundant in fruits and vegetables, especially citrus fruits and red bell peppers. Unfortunately, vitamin C degrades under high heat, so eating foods rich in this nutrient raw or lightly cooked is the best way of getting the maximum amount to benefit your immune system.

Foods high in vitamin B6 include:

  • Fortified grains and cereals
  • Beef
  • Eggs

Probiotic foods, such as live culture yogurt, are good for your immune system.

How To Integrate Vitamins Into Your Daily Diet

While vitamin supplements may sound like an easy fix, the best way to ensure a sufficient intake of essential nutrients is to maintain a healthy and balanced diet. Your body tends to absorb and utilise vitamins better from food, while supplements can be of differing quality.

However, eating a balanced diet may not always be feasible, and its possible to still be deficient in a nutrient even if you eat a healthy diet. In this case, vitamin supplements can come in handy.

And while nutrition will definitely play an important role in building a strong immune system, if you want to maximise your chances of avoiding an infection, you may need to address other aspects of your lifestyle too.

Rather than thinking about boosting the immune system, it is better to think about keeping it healthy and balanced, says Jenny Tschiesche, nutritionist and consultant for Nutriburst . Ideally, this balance will be created through both nutrition and lifestyle interventions. Not only do you need to eat and drink well, but there are other important aspects of your health and wellbeing that need addressing for balance. Sleep well, digest well, reduce long term stress, stay connected to friends and eat mindfully.”

  • Yogurt that contains live, active cultures add probiotics for your gut â best when fortified with vitamin D, which is also found in salmon, sardines, and eggs
  • Most citrus fruits are high in vitamin C
  • Red bell peppers are also packed with vitamin C, plus beta carotene
  • Spinach is rich in nutrients like vitamin C, beta carotene, and antioxidants
  • Antioxidant-rich broccoli is a great source of vitamins A, C, and E
  • Almonds are a source of healthy fats your body needs to absorb fat-soluble vitamin E
