Hormonal changes are a natural part of aging—but the foods you eat every day can either support that transition or make symptoms like weight gain, fatigue, and mood swings much worse. As women over 40 enter menopause, shifts in estrogen, progesterone, and insulin sensitivity can make the body more reactive to certain ingredients, especially those that spike blood sugar, increase inflammation, or interfere with metabolism. That’s why what once felt like harmless indulgences may suddenly start working against you.

To learn more, we spoke to Dr. Michael Lahey and Taylor Stolt, RD, who told us about a few common foods and drinks are especially detrimental during perimenopause and menopause, as they can worsen hormonal imbalances and make it harder to maintain a healthy weight. From disrupting estrogen levels to triggering blood sugar crashes and inflammation, the following choices may be sabotaging your wellness goals.

1. Alcohol

Everyone knows the downsides to alcohol, even though it's one of the most popular beverages in the world. Alcohol can actually affect key hormone-regulating processes, especially as the body ages and metabolism slows down. Stolt reveals that alcohol affects almost every hormone in the body, and not in a good way. She says that this drink "impairs liver function, which plays a key role in metabolizing estrogen, leading to imbalances like estrogen dominance. Even one drink can significantly reduce melatonin production, disrupting sleep and triggering a cascade of hormonal issues. Alcohol also lowers progesterone, increases testosterone levels, and weakens adrenal function, contributing to stress hormone imbalances." As time goes by, this can worsen feelings of fatigue, mood swings, and weight gain.

2. Processed meats

Although they're tasty, processed meats like sausages, hot dogs, and deli cuts are some of the worst meats for your health—and that includes your hormonal health. Eating too much of them can increase your estrogen levels and disrupt your hormones, which means that you may want to be especially careful with consuming them during menopause. Plus, these are high in sodium and preservatives, which can lead to bloating and inflammation, among other issues. "These foods can exacerbate menopausal symptoms by increasing inflammation levels in the body," Dr. Lahey tells us. Bloating is already a common complaint during menopause, and the added sodium from these meats only makes it worse. To avoid this, Dr. Lahey recommends choosing lean proteins such as skinless chicken, fish, or plant-based options like legumes and tofu—all of which are great for weight management.

3. Sugary Snacks and Sodas

Sugary snacks like candies and sodas are undeniably delicious—and let's face it, they're oftentimes difficult to resist. Unfortunately, though, their high fructose content is likely to lead to blood sugar spikes and crashes. This rollercoaster effect can throw your hormones off balance and worsen mood swings and fatigue, two common menopausal symptoms. "Sodas and candies trigger irritable moods and undue tiredness that are so noticeable during menopause," Dr. Lahey warns. Plus, all that sugar can contribute to fat accumulation, along with a range of other health risks. Instead, Dr. Lahey recommends opting for fresh fruits or a piece of dark chocolate to satisfy your sweet tooth. If you're craving soda, reach for water infused with lemon or berries. Yum!

4. Refined Carbohydrates

White bread, pastries, and other refined carbs may be delicious indulgences and, in some cases, even kitchen staples, but the sad truth is that they do more harm than good during menopause (and in general). According to Dr. Lahey, "Refined carbs increase weight and insulin levels, making weight loss even more challenging." They can even make mood swings worse, and often leave you feeling drained. Choose whole grains such as quinoa, brown rice, and whole-wheat bread for better blood sugar and energy levels.
