WHAT IS THE GLYCEMIC INDEX?

WHAT IS THE GLYCEMIC INDEX?
Carbohydrates are an essential part of our diets, but not all carbohydrate foods are equal. The Glycemic Index (GI) is a relative ranking of carbohydrate in foods according to how they affect blood glucose levels. Carbohydrates with a low GI value (55 or less) are more slowly digested, absorbed and metabolised and cause a lower and slower rise in blood glucose and insulin levels.

There are three ratings for GI:

Low = GI value 55 or less
Medium = GI value of 56 – 69 inclusive
High = GI 70 or more

So why do we need good quality Low GI carbohydrates?
You need carbs as they break down into glucose in your body providing the main fuel for our brains and nervous systems, the preferred source of fuel for most organs and our muscles during exercise.

To help make healthy low GI choices quick and easy when you’re shopping, the Glycemic Index Foundation developed the GI Symbol. It guarantees that
a food has been tested by independent experts to be low GI and meets strict nutrient criteria.

The glycemic index (GI) is a ranking of carbohydrates on a scale from 0 to 100 according to the extent to which they raise blood sugar levels after eating. Foods with a high GI are those which are rapidly digested and absorbed and result in marked fluctuations in blood sugar levels. Low-GI foods, by virtue of their slow digestion and absorption, produce gradual rises in blood sugar and insulin levels, and have proven benefits for health. Low GI diets have been shown to improve both glucose and lipid levels in people with diabetes (type 1 and type 2). They have benefits for weight control because they help control appetite and delay hunger. Low GI diets also reduce insulin levels and insulin resistance.

Recent studies from Harvard School of Public Health indicate that the risks of diseases such as type 2 diabetes and coronary heart disease are strongly related to the GI of the overall diet. In 1999, the World Health Organisation (WHO) and Food and Agriculture Organisation (FAO) recommended that people in industrialised countries base their diets on low-GI foods in order to prevent the most common diseases of affluence, such as coronary heart disease, diabetes and obesity.

10 Reasons to Eat Clean

eat clean

1. You’ll become more mindful.
Which one takes longer and really makes you slow down? Eating clean also means eating with purpose and savoring food. That means a better relationship with everything from radishes and radicchio to red velvet cupcakes (which you’ll no longer crave).

2. You’ll save money.
Kiss sick days and medical bills goodbye when you get nutrients from eating clean, real food. Plus, shopping locally and in season makes sense– and cents. Planning clean meals for the week is cost-effective if you make a list and stick to it, as there’s no chance of overspending at the store.

3. You’ll live longer.
Study after study has shown that consuming these foods can lengthen your life-span. And in a study published in the American Journal of Epidemiology, European researchers have found that increasing your produce intake to more than 569 grams per day reduces your risk of mortality by 10 %.

4. You’ll have better relationships.
Preparing clean meals takes time, just the kind of time that allows for easy, relaxed conversations with your kids, spouse and other family members and friends. If they’re too busy with screen time to share stove-top time, point them to the Johns Hopkins Bloomberg School of Public Health 2014 study, published in Public Health Nutrition, showing good health comes from home cooking.

5. You’ll be smarter.
Eating a healthy diet rich in fruits, vegetables, fish and nuts keep our minds sharper and our memories stronger by a whopping 24 %, proved a study published in spring 2015 in Neurology. Our brains also function better with nutrients such as omega-3 fatty acids, as shown in Nature Reviews Neuroscience, while they slow and sputter down when we fill them with sugar (including alcohol), fast food and the wrong kinds of fats. If that’s all too much too think about, remember one point from the Nature Reviews Neuroscience report: A balanced diet means better brain health.

6. You’ll have more energy.
Adam and Eve were onto something when they bit into that apple: Fruit is just one of many clean foods that provide an instant dose of energy. High-fiber fruits like apples take longer to digest and can instantly stave off that afternoon slump while providing critical vitamins for the evening ahead. Other pick-me-ups include quinoa, almonds, eggs, kale, citrus fruit and a good-old-fashioned glass of water.

7. You’ll be better in bed.
Mamma mia! Women with metabolic function in Italy and other regions of the Mediterranean enjoy a healthier sex life than those in the US, thanks to the components of their diet– yep, vegetables, fruits, nuts, whole grains and olive oil. That’s what researchers found in a comprehensive study published in the International Journal of Impotence Research.

8. You’ll help the planet survive.
There’s an oft-quoted statistic that food travels approximately 1,500 miles from farmer to consumer in the United States. By eating seasonal and local foods, as recommended by Clean Eating, you can help reduce your carbon footprint. As the American Journal of Clinical Nutrition reported in 2003, “The major threat to future survival and to US natural resources is rapid population growth”and “the lacto-ovo vegetarian diet is more sustainable than the average American meat-based diet.

9. You’ll be stronger.
The lean protein that comprises part of the clean-eating philosophy builds lean muscle mass and boosts metabolism, found a study presented at The Obesity Society’s annual meeting in 2014. Some mighty choices for your muscles (in addition to animal-based products like chicken, fish and lean beef) include quinoa, chickpeas, nuts, spinach and seeds.

10. You’ll be happier.
Food and mood go hand in hand. And the better the food, the better your mood. If you need to brighten your day, go for berries, bananas, coffee, lean proteins, chocolate, omega-3 and turmeric fatty acids, all proven to boost your mental state.
