Starve a fever?

There is an old wives saying, feed a cold and starve a fever, but what does the latest science say?

Although eating less when we are ill can sometimes help us to recover faster.  The loss of appetite when we have an infection is a biological “trick” that simply allows bacteria to spread.  Eating nutritious food when we have an infection can reduce its severity and recover time say researchers.

Researchers have tracked the health of laboratory mice infected with the Salmonella bacteria and found that natural loss of appetite helped the bacteria spread from the intestines to other tissues.  By comparison, mice fed extra calories lived longer.

This discovery could lead to new ways to tackle bacterial infections that don’t rely on antibiotics.

    • raw chicory root
    • raw Jerusalem artichoke
    • raw garlic
    • raw leeks

  • How to test if you have good posture

    We all know that we need good posture.  So today I wanted to share with you how to test if you have good posture.

    The Wall Test - Stand with the back of your head touching the wall and your heels six inches from the baseboard. With your buttocks touching the wall, check the distance with your hand between your lower back and the wall, and your neck and the wall. If you can get within an inch or two at the low back and two inches at the neck, you are close to having excellent posture. If not, your posture may need professional attention to restore the normal curves of your spine.

    The 'Jump' Test - Feel the muscles of your neck and shoulders. Do you find areas that are tender and sensitive? Are the buttock muscles sore when you apply pressure? What about the chest muscles?

    If any of your muscles feel tight, sore or achy then why not book in for a massage.

Maintaing a healthy small intestine is all about controlling your bacteria levels and mucus build-up on your intestinal walls which can cause havoc and deplete your energy levels.  If you have bloating, gas and loose bowel movements you may have a small intestine issues such as:

    • Candida
