Is it OK to drink sparkling wa­ter?

The Tribune (NZ) - - YOUR HEALTH -

Is there such a thing as too much sparkling wa­ter? I typ­i­cally con­sume around a bot­tle (1.5 litre) at night as I find it a lot eas­ier to drink than still wa­ter. With thanks, Peter C.

Hi Peter. Car­bon­ated wa­ter has been in­fused with car­bon diox­ide gas un­der pres­sure, the re­sult pro­duc­ing a bub­bly drink. There are also nat­u­ral sparkling min­eral wa­ters, typ­i­cally cap­tured from min­eral springs, how­ever, these tend to con­tain min­er­als and sul­phur com­pounds.

Most of the re­search that ad­dresses the con­sump­tion of car­bon­ated drinks, is in soft drinks that also in­clude sugar and are there­fore not good for den­tal health. There’s no rea­son to give it up, but as with any­thing I would en­cour­age a mod­er­ate con­sump­tion of sparkling wa­ter. That means not con­sum­ing it for break­fast, lunch and din­ner. Hav­ing a few sparkling wa­ters at night in place of al­co­hol is ob­vi­ously go­ing to be far bet­ter for your health in the long term.

All car­bon­ated bev­er­ages with or with­out sugar con­tain phos­pho­rus. Blood cal­cium and phos­pho­rus lev­els are both reg­u­lated by the parathy­roid hor­mone. High blood phos­pho­rus lev­els pre­vent your body from stim­u­lat­ing the con­ver­sion of vi­ta­min D into its ac­tive form, and from ab­sorb­ing ad­e­quate amounts of cal­cium.

This leads to a re­duced blood cal­cium level and an in­crease in the re­lease of the parathy­roid hor­mone. High lev­els of parathy­roid hor­mone stim­u­late bone re­sorp­tion, or dem­iner­al­i­sa­tion, which can weaken bones.

How­ever, poor bone health is more of­ten seen when a high phos­pho­rus diet is cou­pled with a low cal­cium in­take. So en­joy sparkling wa­ter, but I en­cour­age you to make still wa­ter your main drink.

I’ve no­ticed this win­termy skin has gone quite dry and flaky. What are some nat­u­ral so­lu­tions to help this? Thanks, Ge­orgie

Hi Ge­orgie. Here are some ideas:


Skin loves hy­dra­tion! Your skin is your big­gest or­gan and it needs a steady sup­ply of fluid to stay hy­drated, plump and glow­ing. En­sure that you are drink­ing plenty of fil­tered wa­ter, herbal tea, or­ganic bone broth and vege juices to help keep your body and skin hy­drated. Flu­ids also help to flush out any harm­ful sub­stances from the body and pre­vent these sub­stances from need­ing to be ex­creted through the skin, where they can cause dam­age.


Start by eating real food. Real

food, as it comes in na­ture is packed with a range of nu­tri­ents, all of which pro­mote great skin. Avoid pro­cessed food, caf­feine and al­co­hol and no­tice the dif­fer­ence this makes to your skin.

Vi­ta­min C is par­tic­u­larly help­ful for skin as it helps to com­bat free rad­i­cal dam­age, which is part of the cause of ageing and wrin­kles. Vi­ta­min C rich foods in­clude cit­rus fruit, kiwi fruit, cap­sicum and broc­coli.

Skin loves fat! Fat helps the skin to main­tain its mois­ture bar­rier which helps keep skin soft and pre­vent dry­ing. Flaky and dry skin or cracked heels and cu­ti­cles can be a sign that you are lack­ing in es­sen­tial fatty acids.

Omega 3 fatty acids are par­tic­u­larly help­ful for skin, and is the type of fat that most peo­ple are de­fi­cient in.

Oily fish like sus­tain­able sar­dines or salmon, chia seeds, flax seeds, and wal­nuts are all great omega 3 rich fats to in­clude in your diet. Co­conut oil also makes a great top­i­cal mois­turiser to use on dry patches of skin.

It’s fine to en­joy a glass or two of car­bon­ated wa­ter but still is still the best.
