Is soya bad for women's health?
Consumed in many traditional Asian populations for millennia, soya has only been a common part of the Western diet for around 60 years. Now, many of our supermarkets are full of soy milk alternatives, soy burgers and other soya-based meat replacements - not to mention traditional soy-based products like tofu, tempeh, soya milk, miso and soya sauce.

Cons of the Mediterranean Diet

  • Cost. Some consumers do worry about the cost of including fish regularly.
  • Additional Guidance May Be Necessary for Diabetes. Because there is an emphasis on grains, fruits, and vegetables (including starchy vegetables), meals may be high in carbohydrates.
  • Restrictions May Feel Challenging. This diet recommends reducing red meat and added sugar consumption.
  • Concerns About Alcohol Intake. Some experts raise concerns about regular alcohol intake (particularly wine).

Nutrients in cow's milk

Cow’s milk is a good source of:
  • Protein 
  • Calcium
  • Vitamin B12 
  • Iodine
  • Magnesium, which is essential for bone development and muscle function.

Calcium intake

  • If children between one and three consume half a pint of milk, they will consume enough calcium for healthy bone development. 
  • Calcium is crucial during our adolescence for the development of bone strength. If you don't get enough calcium in your teenage years, you run a higher risk of bone weakness.
  • For adults, research is conflicting on whether cow's milk helps to keep bones healthy.

Hormones in cow's milk

The estrogen levels of cows increase 20-fold when they are pregnant. Although one study linked estrogen levels to breast, ovarian and uterine cancers, ingesting hormones through cow's milk is no cause for concern.

Researchers found estrogen levels only affect the reproductive systems in mice when supplemented with 100 times the levels found in cow's milk.

There is no "best diet"

The “best” diet is a theme: an emphasis on vegetables, fruits, whole grains, beans, lentils, nuts, seeds, and plain water for thirst. 

That can be with or without seafood; with or without dairy; with or without eggs; with or without some meat; high or low in total fat.

The "Age" of vegetables

The best vegetables are likely to be fresh and locally sourced, but flash frozen is nearly as good (as freezing delays aging). Those “fresh” vegetables that spend a long time in storage or transit are probably the least nutritious.
