The Soy Debate

What the research says ⬇️

Phytoestrogens are plant compounds in foods that mimic estrogen. They include:

✔️ Isoflavones in soy

✔️ Lignans in flax seeds

✔️ Resveratrol in wine

Research shows that eating more phytoestrogens is correlated with a lower risk of breast cancer in women before menopause and a lower risk of breast cancer recurrence in women after menopause (PMID 35241506 and 38070485).

How much?

The most risk reduction was in women who ate about 60 mg of soy isoflavones per day, or 2-3 servings of soy.

One caveat is that soy is a common allergen, often genetically engineered, and highly processed 😬

So look for organic soy products that are minimally processed—like tofu, tempeh, miso, and edamame.

Nutrients Missing from Low-Carb Diets?

💥 🗞️ New Study!!

When compared with diets not restricting carbohydrates, low-carb diets may lead to nutrient depletions—especially of some B vitamins and magnesium.

This recent study found that some of the nutrient requirements not being met by low-carb diets included thiamine (vitamin B1), iron, calcium, magnesium, and selenium.

Red blood cell levels of thiamine were lower and low levels of magnesium were more common in people following a low-carb diet.

This is not medical advice.

This is just something to be aware of if you have chosen to follow a low-carb diet.

It is always best to make dietary changes under the guidance of a practitioner who understands nutrition, metabolism, and supplementation.

This is our specialty.

Brain Nutrients: My Top 5

💥 5 nutrients for brain health ⬇️⬇️

▪️ Omega-3 Fatty Acids

Fatty acids are the building blocks for nerve cell membranes and important for cell-to-cell communication in the brain.

Food sources: fish, nuts, & seeds

▪️ B Vitamins

B vitamins act as cofactors for energy metabolism, and the brain needs a constant supply of energy to maintain function!

Food sources: eggs, meats, nuts, whole grains

▪️ Choline

Choline is a building block for acetylcholine, a key neurotransmitter related to memory and brain function.

Food sources: egg yolks & liver

▪️ Polyphenols

These colorful compounds in plant foods protect brain cells from oxidative stress and damage.

Food sources: berries, chocolate, & green leafy vegetables

▪️ Probiotics

Probiotics influence brain health through the gut-brain axis, benefiting mood and memory.

Food sources: yogurt, kefir, & kombucha

If you aren’t eating food sources of these nutrients every day, supplementation is an option. Just be sure to purchase them from trusted sources. If you have any questions, we can help!

Brain Facts You Don’t Know

Let’s break this down👇

(Brain health facts you may not know!)

1️⃣ 60% of the human brain is fat

Ever think about what happens to fats from your diet once you eat them? They become building blocks for things like cellular membranes, nerve cells, and brain matter! That means eating healthy fats is one of the best things you can do for your brain.

2️⃣Sleep removes toxins from the brain.

The brain actually has a self-cleansing mechanism that creates waves of fluid to clear metabolic waste. These waves are most active during sleep, so you can think of sleep as a form of detox for the brain.

3️⃣Gut microbes signal the brain and affect behavior.

The gut-brain axis is a two-way communication network between the gut and the brain that is largely influenced by the gut microbiome. Studies have even linked specific probiotics to stress and mood.

Is any of this making you think about the brain in a little different way?

Truth is that brain health is about so much more than memory. Brain health depends on our everyday habits and influences our overall health.
