Transcript

  • 1. + Diet, TV & Fertility Amanda Clark, ( Adv APD) Senior Dietitian, Great Ideas in Nutrition, www.greatideas.net.au
  • 2. + The affect of diet and watching TV on fertility Research shows that the foods we eat as well as our activity level can affect fertility A recent Harvard study found that a lazy lifestyle and poor food choices can reduce fertility in men and women
  • 3. + Diet and fertility in women Women who's diets were high in processed carbohydrates and had larger serving sizes had double the risk of ovulation problems Diets containing beans, lentils, tofu, nuts and seeds were associated with more pregnancies High fat processed foods like cakes, biscuits and fried foods were associated with a higher risk of infertility (foods with trans fats) These food choices are also associated with heart disease and diabetes
  • 4. + TV and fertility in men Men who watched TV for more than 20 hours had nearly half the sperm count of men with the lowest TV watching time The most active men had 70% higher sperm counts than the couch potatoes Why? Sitting still and watching TV seems to heat up the scrotum and kill off sperm
  • 5. + Cause for concern?  The foods associated with reduced fertility are also associated with heart disease and diabetes  Diets high in saturated fats, trans fats and processed carbohydrates increase the risk of:  Overweight and obesity  High blood pressure, heart attack and stroke  Type 2 Diabetes  Reduced fertility
  • 6. + Carbs, Glycemic Index and Glycemic Load  Glycemic Index ranks foods based on their effect on blood sugar levels.  High GI foods are digested very quickly and cause your blood sugar levels to spike. Low GI foods provide a slow rise in blood sugar levels and keep you feeling fuller for longer  Glycemic load (GL) = the Glycemic Index (GI) of a food multiplied by the amount of carbs in the food  If you eat a huge bowl of a low GI food such as pasta this can still cause a big rise in blood sugar levels because the meal has a higher GL  Aim for low GI carbs in smaller portion sizes to increase your chance of falling pregnant  Low GI foods include wholegrain breads and cereals such as rolled oats, pasta, basmati rice, legumes (baked beans, lentils, chickpeas etc), sweet potato and corn
  • 7. + Increasing intake of plant proteins and reducing meat intake Sources of plant protein Why eat plant protein? Legumes (lentils, chickpeas, baked beans etc)  Plant proteins are high in fibre, low in saturated fat and full of beneficial vitamins, minerals and antioxidants Plant proteins are often a lower calorie option compared to meat  Reducing meat intake and increasing plant protein foods may improve your fertility Nuts, seeds and nut/seed spreads     Tofu, tempeh  Grains, especially amaranth and quinoa
  • 8. + Reducing intake of trans fats What are trans fats?    Trans fats are made when vegetable oils are hydrogenated (a process that turns liquid vegetable oils into solid fats). If you eat a lot of trans fat this can increase your LDL (bad) cholesterol, decrease your HDL (good) cholesterol and increase your risk of heart disease Lay off trans fats to increase your fertility Sources of Trans fats  Baked foods such as pastries, pies, biscuits and cakes  Fast-food and fried foods such as hot chips  Trans fats also occur naturally (in small amounts) in cow and sheep products such as dairy, beef and lamb. These are thought not to be as bad as the artificial trans fats in fried and baked food
  • 9. + Weight and fertility Weight  Being overweight (in both parents) or underweight can reduce fertility  Research shows that achieving a healthy body weight is associated with better fertility  Daily exercise can help you lose weight or maintain a healthy weight  Exercise can also reduce your risk of developing Gestational Diabetes during pregnancy
  • 10. + Other factors Smoking  Smoking reduces fertility in males and females  Smoking increases the risk of miscarriage, ectopic pregnancy, premature birth and still birth Alcohol  If you or your partner drink alcohol this can reduce the chances of falling pregnant  A baby’s organs begin to grow in the first few weeks of pregnancy. In these early weeks often women don't know they are pregnant.  Avoid alcohol if you are planning to fall pregnant
  • 11. + Summary Reducing your intake of high fat and processed foods, choosing low GI carbohydrates, increasing intake of plant proteins and selecting the correct portion sizes may help you fall pregnant. Following these food choices may also help you achieve and maintain a healthier weight, as well as reduced your risk of heart disease and type 2 diabetes.
