I recently posted about getting lean and the importance of protein. I’ve been promising info on what kinds of protein affect fertility…..here it is…finally!
Protein, carbs and fats all have important uses in our bodies and are all important for our bodies to perform in tip-top shape, especially when we are asking it to create life! I recently posted on how much protein we need for fertility but, will the types of protein we choose effect fertility? According to my research…possibly.
A study as cited in The Fertility Diet showed a possible increase in ovulatory infertility by approximately 39% in women with the highest intake of animal protein than in those with the lowest. The reverse was found to be true regarding plant proteins.
Recent studies suggest replacing animal protein with plant protein because there is possibly…
- an increased risk of ovulatory infertility w/ one serving of red meat, chicken or turkey
- no influence on ovulatory infertility w/ one serving of fish or eggs
- modest protection against ovulatory infertility with plant proteins
These studies suggested that plant protein may be better for good health and fertility than animal protein. It makes sense, right? If it has been recommended to eat full fat dairy to avoid unnecessary hormones, it would make sense that the hormones in our meats may affect our own hormone balance and thus our fertility!
But, I won’t be cutting animal proteins completely out of my diet! Personally, fish and eggs are daily staples around here. Chicken is eaten often as well. I I don’t eat red meat much anymore b/c I just don’t like it and there’s really no reason to force it (it can be good for muscle growth but that’s not my main concern right now). This book and the studies in it are not scaring me away from animal protein. I know that fishes, chickens and turkeys are better for me than cows. I know that plant proteins are also good for me so I eat those too.
The book says that plant protein is best and to try to get half of your daily protein from plant sources. Next is fish and poultry (including eggs). Last, is beef, pork, and lamb (eat the leanest cuts you can find and only rarely). My nutrition studies have suggested getting at least 1/3 of your protein intake from animal sources. You decide what’s best for you!
What am I? I’M A FLEXITARIAN!! Ok, not really in the book’s definition, but I’m flexible! Be flexible! Variety is the key to proper nutrition so vary your diet! That’s a good thing!
If you do choose to cut out all animal protein, which I am in no way suggesting, be careful! Please do appropriate research on vegetarian and vegan diets to be sure you are adequately nourished. If you are not consuming complete proteins (found in meat, fish, poultry, cheese, eggs, milk and some soybean products), you must ensure that you are consuming complementary proteins or at least varying your diet enough (each meal and throughout the day) that you are getting all of the different essential amino acids. I could talk much longer about this subject but I think that if you choose to go this route you need to do more research than one paragraph on my blog. I’m am not an expert regarding vegan or vegetarian diets!
Are you a flexitarian, a vegetarian, a vegan, a meat-itarian? 🙂
