Let’s face it, if you live in the Northern hemisphere getting enough of the “sunshine vitamin,” vitamin D, can be a challenge during the winter months.
If you ‘ve been reading my Health eTips for a while, you know that this miracle vitamin can keep bones strong through menopause as well as keep dementia at bay and improve your mood.
And new research out of Japan shows that a daily dose of vitamin D is also a simple way to keep your glucose levels out of the danger zone.
The new study, conducted on healthy adults, found that even low doses of vitamin D – about 420 IU daily for a year – can shave three points off your fasting glucose levels. The subjects in the study saw an average drop from 88.3 down to 85.3 mg/dL.
Mainstream doctors may give the “thumbs up” as long as it’s below 5.5 mmols/l (100 mg/dl), but the latest science out there indicates that it’s better to keep your blood sugar levels below 4.4 (80 mg/dl) if you can, and no higher than 90.
In fact, a 2008 study showed that people with fasting blood glucose levels in the “safe range” of 5.2 – 5.4 mmols/l (95 to 99 mg/dl) were more than TWICE as likely to develop diabetes; and those in the 5.0 – 5.2 mmols/l (90 to 94 mg/dl) range were 50 per cent more likely to progress to diabetes.
In a related study, otherwise healthy men with fasting blood glucose levels of 4.7 mmols/l (85 mg/dl) or higher had significantly higher heart disease risk than those who kept it below 4.5 mmols/l (81 mg/dl).
While a vitamin D supplement – I recommend about 2,000 IU daily – is a great addition to your daily arsenal for many reasons, it doesn’t have to work alone.
Following a natural, healthy diet that restricts carbohydrates and increases your protein and good saturated fat intake can help manage your blood sugar levels in the long run. The Paleo diet focuses on meats, veggies and fruits and omits processed foods or foods with refined sugars so you’ll keep those glucose numbers well below “normal.”
And as I shared with you recently, you can also control your blood sugar by just walking on a daily basis… and even better so if you catch a bit of direct sunlight while you’re doing it.
Wishing you the best of health,
