Foods Women Should Avoid After 30 (And What to Eat Instead)

It is not only a birthday moment, but the start of a biological transition when one reaches 30. Most women start wondering about the changes they did not even care about before:

• Weight gets attached on suddenly.
• Breakouts happen more often
• PMS becomes more intense
• Sleep gets lighter
• The digestion is also sensitive.
• Energy dips
• The stress has new effects on the body.
• Skin gradually becomes unelastic.

All this does not imply that your body has been aging poorly.

Certain foods that were good in your teens and twenties begin to cause more serious issues, particularly with the changes to the hormones, slower metabolism, and increased inflammation.

Why Diet Matters More After 30

Those women over age 30 begin to experience:

Slower Metabolism

The calorie burn rate in rest begins to drop, that is, some foods can cause weight gain at a much higher rate.

Hormonal Fluctuations

The levels of estrogen, progesterone, and testosterone start to vary – even at the age before perimenopause.
Food turns out to be a significant balancing agent.

Drop in Muscle Mass

Slows down the fat burning process and influences the insulin sensitivity.

Decline in Collagen

Causing apparent skin aging, pain in joints and weaker hair.

Hypersensitivity of Cortisol Response

Women are worse hit by stress beyond 30 years.

Gut Sensitivity

Females are predisposed to bloating, IBS, constipation, and inflammation.

This implies that the foods you consume today contribute enormously to the extent to which you are healthy, energetic and youthful in 30s, 40s, 50s and others.
